April 24, 2025

Saxml on GKE is de-prioritized beginning April 24, 2025. This means the project won't get further updates. Existing Saxml deployments will continue to function as is without disruption. We strongly suggest that you migrate to JetStream, Google's up to date open source inference framework for high-performance LLM serving on TPUs and GPUs. JetStream offers continuous batching and quantization for better throughput and memory efficiency. For a migration example, see Serve Gemma using TPUs on GKE with JetStream.

March 21, 2025

In GKE version 1.32.2-gke.1652000 and later, new external LoadBalancer Services use zonal Network Endpoint Group (NEG) backends by default. This applies only to new backend service-based external LoadBalancer Services. Existing LoadBalancer Services are not affected. To learn more, see Create a backend service-based external load balancer.

All GKE clusters now export four new rollup metrics by default at no additional charge. These new metrics are for monitoring GKE TPU NodePools and JobSets:

• kubernetes.io/node_pool/accelerator/times_to_recover: Distribution of recovery period durations. Each sample indicates a single recovery operation for the NodePool to recover from a downtime period. The data is sampled within 60s after the completion of NodePool recovery, and emitted within 24h. This metric does not include a sample for downtime period longer than 7 days. This metric is only applicable for GKE multi-host TPU node pools.

• kubernetes.io/jobset/times_between_interruptions: Distribution of times between the end of last interruption and beginning of current interruption for a JobSet. Each sample indicates a single duration between last and current interruption. The data is sampled within 60s after the current interruption starts, and emitted within 24h. The metric does not include a sample for duration between interruptions longer than 7 days. This metric is only applicable for JobSets running on nodes with GPU/TPU and having a single replicated job.

• kubernetes.io/jobset/times_to_recover: Distribution of recovery period durations. Each sample indicates a single recovery operation for the JobSet to recover from a downtime period. The data is sampled within 60s after the completion of JobSet recovery, and emitted within 24h. This metric does not include samples for downtime periods longer than 7 days. This metric is only applicable for JobSets running on nodes with GPU/TPU and having a single replicated job.

• kubernetes.io/jobset/uptime: Total time the JobSet has been available. The data is sampled every 60s and emitted within 24h after sampling. This metric is only applicable for JobSets running on nodes with GPU/TPU and having a single replicated job.

Starting in GKE version 1.32.1-gke.1729000, Autopilot clusters will automatically use the new Performance HPA Profile. This new profile enables faster autoscaling on CPU and Memory metrics for up to 1,000 HorizontalPodAutoscaler objects by routing autoscaling metrics through the gke-metrics-agent Daemonset. If desired, users can revert to the old autoscaling profile by disabling the Peformance HPA Profile.

GKE now allows you to enable logging of Horizontal Pod Autoscaler decisions starting from GKE version 1.31.5-gke.1090000 or later, or version 1.32.1-gke.1260000 or later. These logs include atomic recommendations (based on individual metrics) and final recommendations (consolidated HPA decisions). The logs are stored in Cloud Logging and offer insights into the decision-making process of the Horizontal Pod Autoscaler.

You can now monitor startup latency of Kubernetes workloads and nodes using the new Startup Latency dashboard available in the Observability tab on the Deployment details and Cluster details pages in the GKE Console. The dashboard is useful for tracking, troubleshooting and optimizing startup latency of your GKE workloads.

New recommendations of NODE_SA_MISSING_PERMISSIONS subtype are added to the portfolio of GKE Recommendations. Use the new recommendations to identify clusters with node service accounts missing IAM permissions that are critical for normal cluster operations.

If your organization has a policy to disable automatic role grants to default service accounts, the created default GKE node service account will not get the necessary permissions. Missing critical permissions can degrade your essential cluster operations, such as logging and monitoring.

Three new metrics are added for checking node and node pool status:

• kubernetes.io/node/status_condition: The condition of a node from the node status condition field. The Ready field has Unknown status if the node controller has not heard from the node in the last node-monitor-grace-period period. This metric is available for clusters with GKE version 1.32.1-gke.1260000 and later.

• kubernetes.io/node_pool/multi_host/available: The multi-host NodePool availability. When all the nodes in the node pool are available, the value is True. If any of the nodes in the node pool are unavailable, the value is False. This metric is available for Multi-host TPU node pools only.

• kubernetes.io/node_pool/status: The current status of the node pool from the NodePool instance. Status updates happen after GKE API operations complete. This metric is available for Multi-host TPU node pools only.

February 21, 2025

In GKE version 1.33 and later, if you omit the whenUnsatisfiable field in a new GKE compute class specification, the default value is DoNotScaleUp.

In GKE versions earlier than 1.33, the default value is ScaleUpAnyway. Ensure that your compute class specifications explicitly set a value in the whenUnsatisfiable field after you upgrade to version 1.33. This change only affects new ComputeClass objects that you create that omit the whenUnsatisfiable field. Any existing compute classes that omit the field continue to use ScaleUpAnyway as the default value even after you upgrade the cluster to version 1.33 or later.

To learn more about the whenUnsatisfiable field, see Define scaling behavior when no priority rules apply.

GKE Managed NVIDIA Data Center GPU Manager (DCGM) Metrics Package is now generally available for both GKE Standard and Autopilot clusters running version 1.32.0-gke.1764000 and later. You can enable the feature via the Console, gcloud, or Terraform. Starting with cluster version 1.32.1-gke.1357000, GKE Managed NVIDIA DCGM will be default-on for new clusters.

GKE Managed DCGM provides a curated set of metrics for monitoring the utilization, performance, and health of NVIDIA GPUs. These metrics are collected by Google Cloud Managed Service for Prometheus and you can view the metric charts in the Observability Tab on the Kubernetes Clusters page or in Cloud Monitoring. For more information, see Collect and view DCGM metrics.

To learn more, see Collect and view DCGM metrics.

New GKE 1.27 patch versions starting with version 1.27.16-gke.2440000 are built with COS 109, because COS 105 is near the end of support. GKE makes new 1.27 patch versions available using COS 109. However, GKE won't auto-upgrade nodes across the COS milestone boundary, from a patch version using COS 105 to a patch version using COS 109.

If you manually upgrade your nodes to 1.27.16-gke.2440000 or later, GKE continues node auto-upgrades as normal. Control plane upgrades are unaffected, and cluster auto-upgrades to the next minor version towards the end of extended support proceed as normal.

To learn more, see Container-Optimized OS updates during the extended support period.

GKE automatically adds the following resource labels to node pools:

• goog-gke-accelerator-type: The accelerator type used in the node pool.
• goog-gke-tpu-node-pool-type: The TPU node pool type, which can be single-host or multi-host.
• goog-gke-node-pool-provisioning-model: The provisioning model of the node pool. The nodes can be on demand, by reservation, or Spot VMs.

To learn more, see Automatically applied labels.

Starting on July 1, 2025, new organizations will no longer be able to create GKE clusters with Identity Service for GKE. You can continue to use Identity Service for GKE in existing organizations, but we encourage you to migrate to Workforce Identity Federation.

Workforce Identity Federation is the recommended method for configuring access to your GKE clusters from external identity providers. Workforce Identity Federation provides a single hosted solution for managing external IdPs across Google Cloud products. Unlike Identity Service for GKE, Workforce Identity Federation doesn't install components in your cluster.

For details and migration instructions, see Use external identity providers to authenticate to GKE.

Starting on February 3, 2025, GKE will create a new service agent named service-{PROJECT_ NUMBER}@gcp-sa-gkenode.iam.gserviceaccount.com that the GKE system workloads that run on your worker nodes can use. This service agent will only have the minimum permissions that GKE needs to operate these nodes by default, and will help to isolate the requirements of GKE-managed workloads from the requirements of your workloads. GKE-managed system workloads will begin using this service agent in an upcoming GKE version, which we'll announce in a separate release note.

1.32 is now available in the Rapid channel

Kubernetes 1.32 is now available in the Rapid channel. For more information about the content of Kubernetes 1.32, read the Kubernetes 1.32 Release Notes.

New features

• Dynamic Resource Allocation graduated to beta, and enables efficient scheduling of advanced device driver resources (because this is a beta API, using it in GKE clusters requires opt-in).
• Support for more efficient API streaming graduated to beta and is enabled by default in the API server. Clients can opt into use of this more efficient mechanism.
• Support for recovery from volume expansion failure graduated to beta and is enabled by default.
• Support in the Job API for management by external controllers graduated to beta and is enabled by default. This enables integrations with external controllers like MultiKueue.

Deprecated in Kubernetes 1.32

• The following Beta versions of graduated APIs were deprecated in 1.29 and removed in 1.32 in favor of newer versions:

  • flowcontrol.apiserver.k8s.io/v1beta3 FlowSchema, PriorityLevelConfiguration
    • deprecated since 1.29, will no longer be served in 1.32,
    • instead, use flowcontrol.apiserver.k8s.io/v1, available since 1.29.

• The status.nodeInfo.kubeProxyVersion field in the Node API is deprecated and will not be populated starting in v1.33. The field is currently populated with the kubelet version, not the kube-proxy version, and might not accurately reflect the kube-proxy version in use. For more information, see KEP-4004.

December 16, 2024

Cloud DNS additive VPC scope is now generally available on GKE clusters running version 1.28.3-gke.1430000 or later. You can now configure your GKE clusters to add GKE headless service entries to your Cloud DNS private zone visible from your VPC networks, on top of using Cloud DNS (cluster scope) as your GKE DNS provider.

To learn more, read Cloud DNS scopes for GKE.

Trillium, our sixth-generation TPU, is now generally available. Support is available for GKE Standard clusters in version 1.31.1-gke.1846000 or later, and Autopilot clusters in version 1.31.2-gke.1384000 or later. You can use TPU Trillium in the us-east5-b, europe-west4-a, us-east1-d, asia-northeast1-b, and us-south1-a zones.

To learn more, see Benefits of using TPU Trillium.

GKE now provides insights and recommendations that help you identify and amend clusters running a minor version that reached end of standard support, clusters with nodes in violation of version skew policy, and clusters without a maintenance window to achieve reliable operations, up-to-date security posture and supportability.

The C4A machine family is generally available in the following versions:

• Standard clusters in version 1.28.13-gke.1024000, 1.29.8-gke.1057000, 1.30.4-gke.1213000 or later. To use this family in GKE Standard, you can use the --machine-type flag when creating a cluster or node pool.

• Autopilot clusters in 1.28.15-gke.1344000, 1.29.11-gke.1012000, 1.30.7-gke.1136000, 1.31.3-gke.1056000 or later. To use this family in GKE Autopilot, schedule your workloads along with the kubernetes.io/machine-family: c4a node selector. In versions 1.31 or above, the kubernetes.io/arch: arm64 node selector would default to C4A machine family.

Cluster autoscaler and node auto-provisioning are supported in 1.28.15-gke.1344000, 1.29.11-gke.1012000, 1.30.7-gke.1136000, 1.31.3-gke.1056000 or later.

Local SSD support is available for Public Preview from 1.31.1-gke.2008000. Contact your Account Team to participate in the preview.

Clusters now have unified and flexible configuration, allowing you to modify control plane access and cluster node settings at any time, without the need to recreate the cluster. This eliminates the previous distinction between private and public clusters. All clusters support this flexibility and utilize DNS-based endpoints for secure and direct control plane access from any network, removing the need for bastion hosts or proxies. You can still enhance security with measures like VPC Service Controls.

To learn more, see About network isolation in GKE.

DNS-based access for GKE clusters control plane is now generally available. This capability provides each cluster with a unique domain name system (DNS) name or fully-qualified domain name (FQDN). Access to clusters is controlled through IAM policies, eliminating the need for bastion hosts or proxy nodes. Authorized users can connect to the control plane from different cloud networks, on-prem deployments, or from remote locations, without relying on proxies.

To learn more, see About network isolation in GKE.

November 08, 2024

The machine family of N1 custom machine types (like custom-1-1024) is now accurately labeled as "N1" for all node versions later than 1.31.2-gke.1115000.

GKE clusters running version 1.28 or later now support automatic application monitoring in public preview. Enabling this feature automatically deploys PodMonitoring configurations to capture key metrics for supported workloads like Apache Airflow, Istio, and RabbitMQ. These metrics are integrated with Cloud Monitoring dashboards for observability. To learn more, see Configure automatic application monitoring for workloads.

November 06, 2024

The GKE Volume Populator is generally available on GKE clusters running version 1.31.1-gke.1729000 or later. This feature provides a way to automate data transfer from a Google Cloud Storage bucket source storage to a destination PersistentVolumeClaim backed by a Parallelstore instance.

• a3-highgpu-1g (1 GPU)
• a3-highgpu-2g (2 GPUs)
• a3-highgpu-4g (4 GPUs)

These machine types are available through Dynamic Workload Scheduler Flex Start mode, Spot VMs in GKE Standard mode clusters, or Spot Pods in GKE Autopilot mode clusters. You can only provision these machine types if there's available capacity in your region.

GKE continues to support the 8 GPU H100 80GB machine types: a3-highgpu-8g and a3-megagpu-8g.

The new release of the GKE Gateway controller (2024-R2) is now generally available. With this release, the GKE Gateway controller provides the following new capabilities:

• ReferenceGrant support
• Cloud Armor backend security policy support for internal Gateways
• Regional selection for regional multi-cluster Gateways
• Traffic-based autoscaling for single cluster Gateways

Conformance:

• GKE Gateway is now conformant to Gateway APIs v1.1.0

To learn more about our GKE Gateway controller capabilities, see the supported capabilities per GatewayClass.

In GKE clusters with the control plane running version 1.29.1-gke.1425000 or later, TPU slice nodes support SIGTERM signals that alert the node of an imminent shutdown. The imminent shutdown notification is configurable up to five minutes in TPU nodes. To configure GKE to terminate your workloads gracefully within this notification timeframe, see Manage GKE node disruption for GPUs and TPUs.

October 16, 2024

In GKE version 1.31.1-gke.1621000 and later, the kube_pod_resource_request metric and the kube_pod_resource_limit metric are exported as part of the the scheduler metrics package.

October 15, 2024

On GKE Autopilot clusters running version 1.30 and later, partner workloads that set AppArmor profiles might unexpectedly be rejected at admission. This might include installations of Prisma Defender, Wiz Runtime Sensor, Sentinel One Agent, Checkpoint CloudGuard, Aqua Security Enforcer and Splunk OTEL Collector.

The following GKE versions contain a fix for this issue:

• 1.30.5-gke.1355000 and later
• 1.31.1-gke.1621000 and later

Clusters in any release channel can be created on or upgraded to these versions. For details, see Manually upgrading the control plane.

You can now create workloads with multiple network interfaces in GKE Autopilot clusters running version 1.29.5-gke.1091000 and later or version 1.30.1-gke.1280000 and later. For more information, see Setup multi-network support for Pods.

For newly-created VPC Peering-based clusters running version 1.27 or later, traffic from the kube-apiserver to nodes routes through the Konnectivity service. For existing VPC Peering-based clusters, GKE gradually migrates your cluster to use the Konnectivity service.

CVE-2024-45016 was discovered in the Linux kernel, which can lead to a privilege escalation on Container-Optimized OS and Ubuntu nodes.

For more details, see the GCP-2024-057 security bulletin.

The following beta APIs were added in Kubernetes 1.31 and are available in GKE version 1.31.1-gke.1361000 and later:

• networking.k8s.io/v1beta1/ipaddresses
• networking.k8s.io/v1beta1/servicecidrs

Enabling both APIs at the same time enables the Multiple Service CIDRs Kubernetes feature in a GKE cluster. For more information, see the following resources:

• KEP-1880 - Multiple Service CIDRs
• Extended Service IP ranges

During the beta phase, you can only create Service CIDRs in the 34.118.224.0/20 reserved IP address range to avoid possible issues with overlapping IP address ranges.

GKE now supports the Parallelstore CSI driver in allowlisted general availability (GA), which means that you can reach out to your Google support team to use the service under GA terms.

Parallelstore accelerates AI/ML training and excels at saturating individual compute clients, ensuring that expensive compute resources are efficiently used. The product demonstrated a 3.9x training time improvement and 3.7x better throughput improvement compared to native ML framework data loaders and saturates single clients NIC bandwidth at 90%+.

For details, see About the GKE Parallelstore CSI driver.

In GKE version 1.30.3-gke.1639000 and later and 1.31.0-gke.1058000 and later, GKE can handle GPU and TPU node disruptions by notifying you in advance of a shutdown and by gracefully terminating your workloads. This feature is generally available. For details, see Manage GKE node disruption for GPUs and TPUs.

GKE clusters using the Network Policy feature and Pods specifying a hostPort might have experienced networking connectivity issues after control plane upgrades. As a precaution, GKE disabled auto-upgrades for potentially impacted clusters.

The following GKE versions contain a fix for this issue and are safe to manually upgrade to:

• 1.27.16-gke.1342000 or later
• 1.28.13-gke.1078000 or later
• 1.29.8-gke.1157000 or later
• 1.30.4-gke.1282000 or later
• 1.31 or later

GKE control plane upgrades are now resumed and clusters will be auto-upgraded when the patch version becomes an auto-upgrade target for your clusters, honoring maintenance windows and exclusions.

September 23, 2024

September 10, 2024

We previously identified a potential issue that could cause downtime for traffic directed to your GKE-managed internal passthrough Network Load Balancers after certain cluster operations, like node upgrades. This issue specifically affected clusters with GKE subsetting and Services configured with externalTrafficPolicy=Cluster. See the Aug 14, 2024 release note for details.

A fix for this issue is now available. We recommend upgrading your GKE cluster's control plane to the following patch versions or later:

• 1.27.16-gke.1258000
• 1.28.13-gke.1024000
• 1.29.8-gke.1057000

For GKE versions 1.29 and later, the gke-metrics-agent Pod runs with the prometheus-metrics-collector container in addition to the existing gke-metrics-agent and core-metrics-exporter containers. This change might result in an increase in the Service time series ingestion requests per minute quota; however, there is no additional cost.

1.31 is now available in the Rapid channel

Kubernetes 1.31 is now available in the Rapid channel. For more information about the content of Kubernetes 1.31, read the Kubernetes 1.31 Release Notes.

New features

The following features are new in Kubernetes 1.31:

• Field selectors for custom resources is beta and enabled by default.
• matchLabelKeys and mismatchLabelKeys for Pod Affinity and Pod Anti Affinity are beta and enabled by default.
• Traffic distribution for Services is beta and enabled by default.
• Transition kubectl from SPDY to WebSockets is beta and enabled by default.
• Recursive Read-only (RRO) mounts is beta and enabled by default.
• Job success/completion policy is beta and enabled by default.
• Always Honor PersistentVolume Reclaim Policy is beta and enabled by default.
• procMount security context option is beta and enabled by default.

Deprecated APIs in 1.31

• The following Beta versions of graduated APIs were deprecated in 1.29 in favor of newer versions:
  • flowcontrol.apiserver.k8s.io/v1beta3 FlowSchema, PriorityLevelConfiguration
    • deprecated since 1.29, will no longer be served in 1.32
    • instead, use flowcontrol.apiserver.k8s.io/v1, available since 1.29
• The status.nodeInfo.kubeProxyVersion field in the Node API is deprecated and will not be populated starting in v1.33. The field is currently populated with the kubelet version, not the kube-proxy version, and might not accurately reflect the kube-proxy version in use. For more information, see KEP-4004.

Deprecated in-tree volume support

• The Ceph CephFS (kubernetes.io/cephfs) and RBD (kubernetes.io/rbd) volume plugins are deprecated since 1.28 and are removed in 1.31.

• To determine if you have volumes/pods using RBD or Ceph volumes, run the following commands. If either of them print output, then you are using a deprecated volume type.

  • kubectl describe pv | egrep \-i 'Type: \*(RBD|CephFS)'
  • kubectl describe pod \-A | egrep \-i 'Type: \*(RBD|CephFS)'

• Switch to use an RBD or CephFS CSI driver (like the CSI drivers provided at https://github.com/ceph/ceph-csi/), or a Google Cloud-managed solution like Filestore.

• For more information, refer to the OSS Kubernetes announcement and https://github.com/ceph/ceph-csi/

The C4 machine family is generally available in the following versions:

• Standard clusters in version 1.29.2-gke.1521000 and later. To use this family in GKE Standard, you can use the --machine-type flag when creating a cluster or node pool.
• Autopilot clusters in 1.30.3-gke.1225000 and later. To use this family in GKE Autopilot, you can use the Performance compute class when scheduling your workloads.
• Cluster autoscaler and node auto-provisioning are supported in 1.30.3-gke.1225000 and later.

The following vulnerabilities were discovered in the Linux kernel that can lead to a privilege escalation on Container-Optimized OS and Ubuntu nodes:

• CVE-2024-39503

For more details, see the GCP-2024-047 security bulletin.

August 16, 2024

In GKE version 1.29.7-gke.1238000-1.30, and 1.30.3-gke.1571000 or later, node pools use regional instance templates instead of global instance templates. To learn more, see Regional and global instance templates.

We've identified a potential issue that may cause downtime for traffic coming to your GKE managed Internal passthrough Network Load Balancers, after certain cluster operations like node upgrades. This issue specifically affects clusters with GKE Subsetting and Services with externalTrafficPolicy=Cluster.

This issue is more likely to occur in clusters with more than 25 nodes. To prevent this issue altogether, we recommend updating your Service configuration to use externalTrafficPolicy=Local. If you're already experiencing downtime, scale up the number of pods backing your LoadBalancer to provide immediate relief. A fix for this issue will be available in upcoming GKE releases.

In GKE version 1.30 and later, there is a workaround in the PDCSI driver for privileged workloads that access container namespaces with hostpath. The workaround delays NodeUnstage until attached filesystems are no longer in use. Under certain conditions, the privileged hostpath workloads may cause a container's mount namespace to be retained longer than the container's lifecycle. The workaround addresses an issue where the driver could proceed with detaching a GCE persistent disk even if the block device filesystem is still in use.

With this fix, the PDCSI driver will validate that an attached block device is no longer in use prior to unmounting it from a GKE node.

Custom compute classes are a new set of capabilities in GKE that provide an API for fine-grained control over fallback compute priorities, autoscaling configuration, obtainability and node consolidation. Custom compute classes offer enhanced flexibility and control over your GKE compute infrastructure so that you can ensure optimal resource allocation for your workloads. You can use custom compute classes in GKE version 1.30.3-gke.1451000 and later. To learn more, see About custom compute classes.

GKE Autopilot versions 1.28.6-gke.1317000 and later fixes a known issue for ephemeral storage requests. If the combined ephemeral storage requests across all containers in your workload exceed 10 GiB, your workload will be rejected with an error message. This differs from earlier versions, which admitted the workload if it requested more than 10 GiB while only actually provisioning 10 GiB, which would result in workload eviction when the workload used more than 10 GiB.

To ensure uninterrupted operation with GKE Autopilot versions 1.28.6-gke.1317000 and later, do the following:

• Verify that containers injected by webhooks don't cause Pods to exceed the maximum Autopilot resource limits.
• Adjust workload resource requests to account for any containers that may be injected by webhooks.
• If any Pods are rejected after updating, reduce their ephemeral storage requests to meet the limit for your workload configuration.

To learn more, see Automatic resource management in Autopilot.

With GKE patch version 1.30.1-gke.115600 and later, if you don't specify the gpu-driver-version flag when creating new GPU node pools, then GKE automatically installs the default GPU driver version that corresponds to the GKE version. If you prefer to manually install the GPU driver, set gpu-driver-version=disabled. To learn more, see Create a GPU node pool.

In GKE version 1.30.2-gke.1100 and later, the _CMDLINE field is removed from kubelet log entries to reduce log volumes.

If you need to access _CMDLINE information, you have two options:

1. SSH into the node:

   • SSH into the relevant node.
   • Run the following command: ps aux | grep kubelet.

2. Search cloud logging:

   • Use the Cloud Logging interface or API.

   • Apply the following filter to search kubelet startup logs:

     resource.type="k8s_node"
     log_name="projects/{PROJECT_ID}/logs/kubelet"
     resource.labels.cluster_name="{CLUSTER_NAME}"
     SEARCH("`FLAG:`")
     

   Remember to replace {PROJECT_ID} and {CLUSTER_NAME} with the appropriate values for your environment.

In GKE versions starting from 1.29.4-gke.1542000 and earlier than 1.29.7-gke.1008000, while Anthos Service Mesh is enabled, Pods that utilize Google Cloud Storage FUSE CSI driver volumes might encounter scheduling issues, with this error message:

Pod "your-pod-name" is invalid: [spec.volumes[x].name: Duplicate value: "gke-gcsfuse-tmp", spec.initContainers[x].name: Duplicate value: "gke-gcsfuse-sidecar"]

This issue has been resolved in GKE version 1.29.7-gke.1008000.

This feature is Generally Available and production-ready, with support for Autopilot and Terraform. To learn more, see Use secondary boot disks to preload data or container images.

GKE Managed DCGM Metrics Package is now available in Preview for both GKE Standard and Autopilot clusters running version 1.30.1-gke.1204000 and later.

You can now configure Autopilot and Standard clusters to export a predefined list of DCGM metrics emitted by GKE Managed DCGM exporter including metrics for GPU performance, utilization, and I/Os in the GPU node pools with GKE-managed NVIDIA drivers. These metrics are collected by Google Cloud Managed Service for Prometheus. You can view the curated DCGM metrics in the Observability Tab on the Kubernetes Clusters page or in Cloud Monitoring.

For more information, see Collect and view DCGM metrics.

A faulty component in the Persistent Disk CSI (PDCSI) driver may cause mount failures for NVMe block devices on specific GKE clusters. This issue affects machine types that exclusively use the NVMe interface for attached Persistent Disks, such as third-generation machine types, T2A instances, and Confidential VMs. For more details, see About persistent disks.

Impacted GKE versions include:

• 1.30.2-gke.1023000
• 1.27.15-gke.1012000
• 1.27.14-gke.1100000

Mount failures will log errors indicating difficulties verifying and re-linking the GCE Persistent Disk. You will see log errors like this:

"Error when getting device path: rpc error: code = Internal desc = error verifying GCE PD ("$PVC") is attached: failed to find and re-link disk $PVC with udevadm after retrying for 3s: couldn't get serial number for disk $PVC at device path /dev/$NVME_PATH: google_nvme_id failed for device "/dev/$NVME_PATH" with output [**numbers**]: exit status 1"

This issue will be resolved in the next GKE releases. In the meantime, if you are experiencing mount failures, upgrade your cluster to the default version 1.30.1-gke.1329000 for the 1.30 release channel or 1.27.14-gke.1059000 for the 1.27 release channel.

Resource requests for anetd Pods have been increased from 200mil CPU and 110m memory to 205mil CPU and 230m memory. In some cases, if the CPU and memory budgets on the nodes are limited, GKE might evict workloads to facilitate anetd during control plane upgrades. This can occur if your clusters are being upgraded from earlier versions to one of the following versions:

• 1.28.5-gke.1217000 and later
• 1.29 and later
• 1.30 and later

The C4 machine family is available in Public Preview for Standard clusters running GKE version 1.29.2-gke.1521000 and later. You can select this family by using the --machine-type flag when creating a cluster or node pool. The following limitations apply:

• GKE versions prior to 1.29.2-gke.1521000 might encounter a volume device path mounting error which can cause Pods to be stuck in a Pending state. If you encounter this issue, try deleting and re-creating the Pod, to trigger re-processing of the volume mount.
• Confidential GKE nodes are not supported in Public Preview.
• Local SSD is not supported.
• Nested virtualization is not supported in Public Preview.

The GKE Container Security API is now enabled automatically when GKE Enterprise is enabled on a project. This change ensures the security and compliance features are ready for use as part of GKE Enterprise activation.

New features in 1.30

The following features are new in Kubernetes 1.30:

• ValidatingAdmissionPolicy is GA and now enabled by default.
• Validation Ratcheting is beta and enabled by default, and makes CustomResourceDefinitions even safer and easier to manage.

New APIs in 1.30

The following APIs are new in Kubernetes 1.30:

• admissionregistration.k8s.io/v1 ValidatingAdmissionPolicyBinding and ValidatingAdmissionPolicy

Deprecated APIs in 1.30

The following Beta versions of graduated APIs were previously deprecated in 1.29 in favor of newer versions:

• flowcontrol.apiserver.k8s.io/v1beta3 FlowSchema, PriorityLevelConfiguration: Deprecated since 1.29, will no longer be served in 1.32. Instead, use flowcontrol.apiserver.k8s.io/v1, which is available since Kubernetes 1.29
• The status.nodeInfo.kubeProxyVersion field in the Node API is deprecated and will not be populated starting in v1.33. The field is currently populated with the kubelet version, not the kube-proxy version, and might not accurately reflect the kube-proxy version in use. For more information, see KEP-4004.

Deprecated features in 1.30

The Ceph CephFS (kubernetes.io/cephfs) and RBD (kubernetes.io/rbd) volume plugins are deprecated since 1.28 and will be removed in a future release.

To determine if you have volumes/pods using RBD or Ceph volumes, run the following commands. If either of them print output, then you are using a deprecated volume type:

• kubectl describe pv | egrep -i 'Type: *(RBD|CephFS)'
• kubectl describe pod -A | egrep -i 'Type: *(RBD|CephFS)'

Switch to use an RBD or CephFS CSI driver (like the CSI drivers provided in the Ceph CSI driver project), or a Google Cloud-managed solution like Filestore. For more information, refer to the OSS Kubernetes announcement and to the Ceph CSI driver project.

• CVE-2024-1085

For more information, see the GCP-2024-018 security bulletin.

March 14, 2024

A previous version of the GKE logging agent that rolled out in GKE version 1.28.7-gke.1100000 contained a security vulnerability. This version has been immediately removed.

March 11, 2024

Private clusters created on GKE versions 1.29.0-gke.1384000 and later use Private Service Connect (PSC) for nodes to privately communicate with the control plane. There is no price increase for using GKE private clusters running on PSC.

For private clusters created with a different GKE version, the clusters continue to use VPC Peering for node-to-control plane communication.

Secret Manager add-on for GKE is now available. With the add-on, you can access the secrets stored in Secret Manager as volumes mounted in Kubernetes Pods. The add-on is supported on Standard and Autopilot clusters versioned 1.29 and later. For more info, see Use Secret Manager add-on with GKE.

Opportunistic bursting and lower Pod minimums are now available on newly created GKE Autopilot clusters at version 1.29.2-gke.1060000 or later, and on existing clusters created at 1.26 or later that have been fully upgraded (including all nodes) to 1.29.2-gke.1060000 or later. To learn more, see Configure Pod bursting on GKE.

March 08, 2024

For GKE versions later than 1.29.1-gke.1760000, the NEG, Ingress, L4 internal load balancer with subsetting, and L4 RBS controllers will skip processing the nodes missing the topology.kubernetes.io/zone label until the zone information is ready. The load balancer controllers will no longer block sync operations when a node is introduced without the label.

Managed ASM installation and node scaling fails on GKE Autopilot clusters on versions between 1.28.6-gke.1095000 and 1.28.7-gke.1025000 and on versions between 1.29.1-gke.1016000 and 1.29.1-gke.1781000. To mitigate this issue, upgrade the cluster to version 1.28.7-gke.1026000 or later, or 1.29.2-gke.1060000 or later.

With 2024-R07, clusters created in the Rapid channel are defaulting to an affected version. To avoid creating a cluster on an affected version, manually specify version 1.28.7-gke.1026000 or later, or 1.29.2-gke.1060000 or later when creating clusters in the Rapid channel.

March 07, 2024

You can now preload data or container images in new nodes to get fast workload deployment and auto scaling. This feature is available in Preview starting from GKE version 1.28.3-gke.1067000.

A bug in the image streaming feature might cause containers to fail because of a missing file or files.

Containers running on a node with image streaming enabled on the following versions might fail to start or run with errors informing that certain files don't exist. The following are examples of such errors:

• No such file or directory
• Executable file not found in $PATH

The following GKE versions are impacted:

• For 1.27: 1.27.10-gke.1077000 and later
• For 1.28: All 1.28 versions
• For 1.29: All 1.29 versions

GKE is working on fixing the issue. In the meantime, if you are impacted by this issue, please disable image streaming.

You can now use the GKE API to apply Resource Manager tags to your GKE nodes. GKE attaches these tags to the underlying Compute Engine VMs. You can use these tags to selectively enforce Cloud Firewall network firewall policies. This feature is generally available in GKE version 1.28 and later.

Kubernetes Engine best practice observability packages, including control plane logs, control plane metrics, and kube state metrics are now enabled by default for new managed GKE Enterprise clusters to ensure availability of necessary data when it's needed for troubleshooting or optimization. Control plane metrics and kube state metrics are included in GKE Enterprise Edition at no additional charge.

GKE now delivers insights and recommendations if your cluster's Certificate Authority (CA) is expired or will expire in the next 180 days. To learn more, see Find clusters with expiring or expired credentials.

• 1.25.16-gke.1497000
• 1.26.13-gke.1189000

The following vulnerabilities were discovered in the Linux kernel that can lead to a privilege escalation on Container-Optimized OS and Ubuntu nodes:

• CVE-2023-6932

For more information, see the GCP-2024-011 security bulletin.

February 15, 2024

HorizontalPodAutoscaler (HPA) and VerticalPodAutoscaler (VPA) may stop autoscaling all workloads in a cluster if it contains misconfigured autoscaling/v2 HPA objects. The issue impacts clusters running earlier patch versions of GKE version 1.27 and 1.28 (for example, 1.27.3-gke.100).

The fix is available in following cluster versions:

• 1.27.5-gke.1300 and later
• 1.28.1-gke.1400 and later
• 1.29 and later

We recommend that affected customers upgrade clusters to these versions to prevent HPA and VPA from misbehaving when there is at least one misconfigured HPA object.

We recommend that affected customers correct misconfigured autoscaling/v2 HPA objects by making sure the fields in spec.metrics.resource.target match, for example:

• When spec.metrics.resource.target.type is Utilization then target should be averageUtilization;
• When spec.metrics.resource.target.type is AverageValue then target should be averageValue.

For more details on how to configure autoscaling/v2 HPA objects, see the HorizontalPodAutoscaler Kubernetes documentation.

February 14, 2024

The following vulnerabilities were discovered in the Linux kernel that can lead to a privilege escalation on Container-Optimized OS and Ubuntu nodes.

Clusters that are running GPUs and are upgraded from 1.26 to a 1.27 patch version earlier than 1.27.8 might experience issues with their nodes' GPU device plugins (nvidia-gpu-device-plugin). Do the following steps depending on the state of your cluster:

• If your cluster is running version 1.26 and has GPUs, don't manually upgrade your cluster until version 1.27.8 is available in your cluster's release channel. As of the publishing date of this release note, 1.27.8 patch versions are available in the Rapid and Regular channels.
• If your cluster is running an earlier 1.27 patch version and the nodes are affected, restart the nodes or manually delete the nvidia-gpu-device-plugin Pod on the nodes (the add-on manager will create a new working plugin).
• If your cluster is using auto-upgrades, this doesn't affect you as automatic upgrades will only move clusters to patch versions with the fix.

The following vulnerability was discovered in the Linux kernel that can lead to a privilege escalation on Container-Optimized OS and Ubuntu nodes:

• CVE-2023-6817

For instructions and more details, see the GCP-2024-004 security bulletin.

January 22, 2024

We have identified several clusters where users have granted Kubernetes privileges to the system:authenticated group, which includes all users with a Google account. These types of bindings are not recommended, as they violate the principle of least privilege and grant access to very large groups of users. See guidance under 'What should I do' for instructions on how to find these types of bindings.

For more information, see the GCP-2024-003 security bulletin.

1.29 is now available in the Rapid channel

Kubernetes 1.29 is now available in the Rapid channel. For more information about the content of Kubernetes 1.29, read the Kubernetes 1.29 Release Notes.

New Features

• The beta ValidatingAdmissionPolicy feature can be opted into by enabling the beta APIs.
• initContainers can now be configured as sidecar containers and kept running alongside normal containers in a Pod. This is only supported by nodes running version 1.29 or later, so avoid using this feature in Pods if there are nodes running earlier versions in the cluster.

New APIs

• flowcontrol.apiserver.k8s.io/v1 FlowSchema, PriorityLevelConfiguration
  • Notable changes in flowcontrol.apiserver.k8s.io/v1:
    • The PriorityLevelConfiguration spec.limited.nominalConcurrencyShares field only defaults to 30 when unspecified, and an explicit value of 0 is not changed to 30.

Deprecated APIs

• The following Beta versions of graduated APIs are deprecated in 1.29 in favor of newer versions:
  • flowcontrol.apiserver.k8s.io/v1beta3 FlowSchema, PriorityLevelConfiguration
    • Deprecated since 1.29
    • Instead, use flowcontrol.apiserver.k8s.io/v1, available since 1.29
• The status.nodeInfo.kubeProxyVersion field in the Node API is deprecated and will not be populated starting in version 1.33. The field is currently populated with the kubelet version, not the kube-proxy version, and might not accurately reflect the kube-proxy version in use. For more information, see KEP-4004.

Removed APIs

The following Beta versions of graduated APIs are removed in 1.29 in favor of newer versions:

• flowcontrol.apiserver.k8s.io/v1beta2 FlowSchema, PriorityLevelConfiguration
  • Deprecated since 1.26
  • Instead, use flowcontrol.apiserver.k8s.io/v1beta3 available since 1.26, or flowcontrol.apiserver.k8s.io/v1, available since 1.29

Removed SHA-1 certificate support

• Starting from version 1.29, GKE no longer supports webhook backends that use TLS certificates signed with the insecure SHA-1 algorithm. To prevent impact on your clusters, you must replace incompatible certificates of webhook servers and extension API servers before upgrading your clusters to version 1.29.
• GKE will not auto-upgrade clusters with webhook backends using incompatible certificates to 1.29 until you replace the certificates or until version 1.28 reaches end of life. For more information, refer to Ensure compatibility of TLS certificates before upgrading to GKE 1.29.

Deprecated in-tree volume support

• The Ceph CephFS (kubernetes.io/cephfs) and RBD (kubernetes.io/rbd) volume plugins are deprecated in 1.28 and will be removed in a future release.
• To determine if you have volumes or Pods using RBD or Ceph volumes, run the following commands. If either of them print output, then you are using a deprecated volume type.
  • kubectl describe pv | egrep -i 'Type: *(RBD|CephFS)'
  • kubectl describe pod -A | egrep -i 'Type: *(RBD|CephFS)'
• Switch to use an RBD or CephFS CSI driver, such as the drivers provided in the Ceph CSI GitHub repo, or use a Google-managed solution such as Filestore.
• For more information, refer to the OSS Kubernetes announcement and the Ceph CSI GitHub repo.

January 08, 2024

GKE clusters in Autopilot mode no longer require workload-level logging to be enabled. Pass --logging=SYSTEM to create-auto or update to disable workload logs.

December 19, 2023

You can now modify the vm.max_map_count Linux kernel attribute for nodes in a GKE Standard cluster node pool using the node system configuration. To learn more, see Sysctl configuration options.

December 18, 2023

The GKE NEG controller now supports IPv6 endpoints with GKE version 1.28.4-gke.1083000 and later.

With this new capability, when you create a dual stack Service in a dual stack GKE cluster, any NEGs associated with the Service will now contain both IPv4 and IPv6 endpoints. Existing dual stack Services utilizing NEGs (i.e. Ingress, Services using Standalone NEGs) will be migrated from "IPv4 only" endpoints to "IPv4 + IPv6" endpoints.

The migration will be completed in approximately one hour. In the event that a NEG contains a single endpoint, you might experience brief downtime of approximately 1-2 minutes during the migration of that endpoint.

Note that Having IPv6 endpoints in NEGs doesn't necessarily mean that the load balancer uses IPv6 for communication. How the load balancer communicates with your Pod depends on how the BackendService is configured, such as fields like IpAddressSelectionPolicy.

All newly created Google Kubernetes Engine (GKE) Autopilot clusters starting with 1.27.4-gke.900 will automatically collect and send metrics from the kube-state-metrics package to Managed Service for Prometheus.

December 15, 2023

An attacker who has compromised the Fluent Bit logging container could combine that access with high privileges required by Anthos Service Mesh (on clusters that have enabled it) to escalate privileges in the cluster.

For more information, see the GCP-2023-047 security bulletin.

We've identified an issue with configuring TLS for Gateways in clusters running GKE version 1.28.4-gke.1083000. This affects TLS configurations using either an SSLCertificate or a CertificateMap. If you're upgrading a cluster with existing Gateways, updates made to the Gateway will fail. For brand new Gateways, the load balancers won't be provisioned. This issue will be fixed in an upcoming GKE 1.28 patch version.

New inference-focused Cloud Tensor Processing Unit (TPU) v5e machine types are available in GKE. These single-host TPU VMs are designed for inference workloads and contain one, four, or eight TPU v5e chips. These three new TPU v5e machine types (ct5l-hightpu-1t, ct5l-hightpu-4t, and ct5l-hightpu-8t) are currently available in the us-central1-a and europe-west4-b zones.

Cloud Tensor Processing Unit (TPU) v5e is generally available in clusters running GKE version 1.27.2-gke.2100 and later.

TPU v5e is purpose-built to bring the cost-efficiency and performance required for medium- and large-scale training and inference. TPU v5e delivers up to 2x higher training performance per dollar and up to 2.5x inference performance per dollar for LLMs and gen AI models compared to Cloud TPU v4. At less than half the cost of TPU v4, TPU v5e makes it possible for more organizations to train and deploy larger, more complex AI models.

GKE begins automatically upgrading clusters still running version 1.24 to version 1.25 after 1.24 reaches end of life on January 8, 2024. We extended this date from October 31, 2023 to minimize disruptions around the end-of-year holiday period, and will provide patches only for critical vulnerabilities during this extended period. To learn more about the GKE minor version lifecycle, see GKE versioning and support. GKE continues to pause automatic upgrades until January 8, 2024 for clusters still using deprecated APIs removed in version 1.25, including beta APIs and PodSecurityPolicy. We recommend that you upgrade your clusters to version 1.25 as soon as possible as GKE minor versions that have reached end of life will no longer receive security patches and bug fixes.

November 02, 2023

A bug that caused failures when many concurrent operations were run on the same cluster (such as when creating multiple node pools) has been fixed.

October 31, 2023

GKE multi-cluster Gateway is now generally available in GKE versions 1.24 and later for GKE Standard clusters, and versions 1.26 and later for GKE Autopilot clusters. Use the Gateway API to express the intent of your inbound HTTP(S) traffic into your fleet of GKE clusters. The multi-cluster Gateway controller deploys and manages the Application Load Balancers that forward traffic to your applications. To learn more, see Enable multi-cluster Gateways. For the list of supported Cloud Load Balancers and their features, refer to GatewayClass capabilities.

The Cloud Storage FUSE CSI driver now enforces injected sidecar containers to follow the Restricted Pod security standard. This change is available in v0.1.6 of the driver, and in GKE clusters with control planes running the following versions: 1.24.17-gke.2146000, 1.25.14-gke.1466000, 1.26.9-gke.1494000, 1.27.6-gke.1506000, and 1.28.2-gke.1157000 or later.

October 20, 2023

New Autopilot clusters created with versions 1.24.17-gke.2146000, 1.25.14-gke.1466000, and 1.26.9-gke.1494000 or later are now provisioned with e2-small default nodes, which are removed immediately after cluster creation. With this change, DaemonSets are guaranteed to schedule on all candidate nodes if you follow best practices for DaemonSets on Autopilot.

You can now use the GKE API to apply Resource Manager tags to your GKE resources. GKE attaches these tags to the underlying Compute Engine VMs. You can use these tags to selectively enforce Cloud Firewall network firewall policies. This feature is available in Public Preview in GKE version 1.28 and later.

October 19, 2023

Compute resources can now be reserved in advance for use with GKE. Create a future reservation to request assurance of important or difficult-to-obtain capacity in advance. There are no additional costs for creating future reservation requests. You only start to pay when Compute Engine provisions the reserved resources, and you're charged at the same cost as on-demand reservations.

October 10, 2023

A Denial-of-Service (DoS) vulnerability was recently discovered in multiple implementations of the HTTP/2 protocol (CVE-2023-44487), including the golang HTTP server used by Kubernetes. The vulnerability could lead to a DoS of the Google Kubernetes Engine (GKE) control plane. GKE clusters with authorized networks configured are protected by limiting network access, but all other clusters are affected. For more information, see the GCP-2023-030 security bulletin.

October 09, 2023

If you are using a third generation machine series (for example, C3), GKE configures Local SSD volumes as the local ephemeral storage by default. You no longer need to specify the --ephemeral-storage-local-ssd flag when provisioning clusters or node pools. When you configure Local SSD volumes as raw block storage with the --local-nvme-ssd-block flag, specifying the count value is now optional.

October 06, 2023

A previously published release note on December 14, 2022 has been updated. Support for migration of GKE Autopilot clusters' datapath provider to Dataplane V2 has been paused. We will update this release note when migration support resumes.

October 04, 2023

Log rotation is misconfigured on nodes running a COS-based image type (cos_containerd). This affects all COS-based nodes running version 1.28 or higher. As a result of this issue, your logs may fill up the disk and cause your nodes to be marked as 'Not Ready' and to be auto-repaired. As a workaround, use a privileged DaemonSet to change the logrotate path to /usr/bin/ instead of /usr/sbin/ in Systemd unit kube-logrotate.service.

October 02, 2023

GKE now delivers insights and recommendations if users have installed webhooks that intercept system resources or webhooks that have no available endpoints. To learn more, see Ensure control plane stability when using webhooks.

September 29, 2023

This is a follow-up message to the release note regarding blue-green upgrades from September 18, 2023. You can now resume upgrading clusters with the blue-green upgrade strategy as the issue with rollback functionality has been fixed. GKE is no longer blocking automatic upgrades due to this issue.

September 21, 2023

Note: This is a correction of the November 07, 2022 release note, which omitted the applicable version numbers for this feature.

When you create a LoadBalancer service in GKE, the Google Cloud controllers automatically create the following firewall rules and apply them to the GKE nodes to allow inbound connections on the Service port:

• Internal load balancer with GKE subsetting or external load balancer with regional backend services (RBS): k8s2-[cluster-id]-[namespace]-[service-name]-[suffixhash]
• Internal load balancer without GKE subsetting or external load balancer with target pool: k8s-fw-[loadbalancer-hash]

For clusters running version 1.25 or later, these rules now include the load balancer IP address in the destination ranges field to further control the inbound connections to the nodes. You can use the gcloud compute firewall-rules describe command to check a relevant firewall. The new field in the output is similar to the following:

destinationRanges:
- [LOADBALANCER_VIRTUAL_IP_ADDRESS]

For services that use externalIP, ensure you have firewall rules that allow traffic to the specified IP addresses.

The Observability dashboards on the GKE Clusters List, Cluster Details, and Workload List pages are now customizable. Additionally, the Cluster Details dashboards can be customized across the entire project, or per-cluster for specific use cases.

September 19, 2023

The me-central2 region in Dammam, Saudi Arabia is now available.

September 18, 2023

GKE clusters running version 1.28 or later block new bindings of ClusterRole cluster-admin to User system:anonymous, Group system:authenticated, or Group system:unauthenticated due to the security risks of these bindings. GKE does not block existing bindings.

GKE has temporarily paused all automatic node upgrades due to an issue with blue-green upgrades rollback functionality. You can still manually upgrade node pools with the surge upgrade strategy. Do not manually upgrade node pools with blue-green upgrades. GKE is working on a fix for this issue and will post a follow-up note here when the issue is fixed and automatic upgrades resume.

September 12, 2023

You can now use node auto-provisioning for TPU slices. With this feature, Standard clusters with GKE version 1.28 and later provision TPU node pools and multi-host TPU accelerators automatically to ensure the capacity required to schedule AI/ML workloads. To learn more, see Configuring TPU node auto-provisioning.

September 11, 2023

Compute Engine persistent disk CSI Drivers deployed on clusters running version 1.26 and later now support filesystem size expansion during restoration from a snapshot or a clone when the PVC data source is larger than the original volume. For more information, see the GitHub pull request.

September 07, 2023

Three vulnerabilities (CVE-2023-3676, CVE-2023-3955, CVE-2023-3893) have been discovered in Kubernetes where a user that can create Pods on Windows nodes may be able to escalate to admin privileges on those nodes. These vulnerabilities affect the Windows versions of Kubelet and the Kubernetes CSI proxy.

GKE clusters are only affected if they include Windows nodes.

For more information, see the GCP-2023-026 security bulletin.

With the recently released version of GKE, version 1.28, you cannot yet use the SidecarContainer feature with alpha clusters. Pods defining restartable Init containers will not start. This is a known issue that will be resolved in a future release.

For GKE clusters using Dataplane V2, upgrades to GKE version 1.26 might cause GKE to temporarily be unable to configure workloads. In some cases, this might cause existing workloads to temporarily lose networking access. This issue does not impact new clusters and GKE clusters not using Dataplane V2. For clusters running version 1.25 with Dataplane V2 enabled, GKE has temporarily disabled auto-upgrades to version 1.26. We recommend that customers not manually upgrade their Dataplane V2-enabled cluster to GKE version 1.26. This is a known issue for GKE version 1.26 and will be fixed in a future patch version of 1.26.

September 05, 2023

1.28 is now available in the Rapid channel

Kubernetes 1.28 is now available in the Rapid channel. For more information about the content of Kubernetes 1.28, read the Kubernetes 1.28 Release Notes.

New APIs

• The kubectl auth whoami command and the authentication.k8s.io/v1 SelfSubjectReview API enables checking the authenticated user information as seen by the server.

Deprecated API versions

These APIs are still served in version 1.28 but are in a deprecation period:

• The following Beta versions of graduated APIs will be removed in 1.29 in favor of newer versions:
  • flowcontrol.apiserver.k8s.io/v1beta2 FlowSchema, PriorityLevelConfiguration
    • deprecated since 1.26
    • use flowcontrol.apiserver.k8s.io/v1beta3 instead, available since 1.26.

Deprecated in-tree volume support

• The Ceph CephFS (kubernetes.io/cephfs) and RBD (kubernetes.io/rbd) volume plugins are deprecated in 1.28 and will be removed in a future release.
• To determine if you have volumes or Pods using RBD or Ceph volumes, run the following commands. If either of them print output, then you are using a deprecated volume type.
  • kubectl describe pv | egrep -i 'Type: *(RBD|CephFS)'
  • kubectl describe pod -A | egrep -i 'Type: *(RBD|CephFS)'
• Switch to use an RBD or CephFS CSI driver, such as the drivers provided in the Ceph CSI GitHub repo, or use a Google-managed solution such as Filestore. For more information, refer to the OSS Kubernetes announcement and the Ceph CSI GitHub repo.

The recently released version of GKE, version 1.28, has a known regression in behavior. After node restart, Pods that have started initialization before the restart will run Init containers in-parallel with regular containers instead of waiting for Init containers to complete.

To deliver a better default price-performance for applications, all GKE Autopilot clusters with control plane version 1.27.5 and later will use an SSD-based persistent disk for ephemeral storage. This change will only affect newly created clusters and new node pools created in clusters upgraded to version 1.27.5 and later.

It is not yet possible to enable Gateway API support in GKE 1.28 (Standard or Autopilot), this will be fixed in an upcoming patch release to GKE 1.28. Clusters that already have Gateway API enabled before upgrading to GKE 1.28 will continue to be supported. This will not affect existing Gateways.

September 01, 2023

Starting on September 1, 2023, a new automation policy is in effect where GKE automatically starts a credential rotation within 30 days of your cluster's certificate authority expiry date to ensure that your cluster doesn't have a complete outage. For example, if your cluster's CA expires on 2024-01-05, an automatic rotation starts on or after 2023-12-06. Automatic credential rotation is a critical update that ignores any configured maintenance windows.

This automatic rotation might cause API clients outside the cluster, such as kubectl in a local environment, to stop working unless you update those clients to use the new credentials.

You should plan for and perform credential rotations well in advance of your cluster CA expiring to ensure a smooth transition to new credentials and minimal workload disruptions. Don't rely on automatic rotation; it is intended to be a last resort to prevent complete outages. To learn more about the stages of credential rotation, see Rotate your cluster's credentials.

August 31, 2023

For GKE nodes running version 1.25 and later, when Image streaming is enabled, the mv command and renameat2 system call might fail on symlink files in container images with the error message "No such device or address". The issue is caused by a regression on recent Linux kernels. GKE does not currently have a fix for the issue. To learn more, see the troubleshooting section for this issue.

August 30, 2023

GKE now supports the ability to create nodes and workloads with multiple network interfaces. You can create new clusters with version 1.27 and later with multi networking enabled. The additional network interfaces on the Pods can be regular interfaces or high performance interfaces where the network interface is directly attached to the Pod. For more information, see Setup multi-network support for Pods.

Your clusters can now perform operations, such as node auto-provisioning or version upgrades, on multiple node pools in parallel. You no longer have to wait for an operation to complete before you initiate another operation. This feature is enabled for all GKE versions. This change provides you with benefits like the following:

• More efficient scaling, which results in improved savings and faster workload deployment
• Faster, less disruptive node pool upgrades
• Fewer "operation already in progress" messages that could delay subsequent planned operations
• More reliable rollback behavior to fix upgrade-related disruptions in production
• Automatic control plane resize operations won't block other operations on the cluster

The Google Cloud Platform Terraform provider has also been updated to take advantage of this change.

August 29, 2023

You can now create Cloud Tensor Processing Unit (TPU) nodes in GKE to run AI workloads, from training to inference models. GKE manages your cluster by automating TPU resource provisioning, scaling, scheduling, repairing, and upgrading. GKE provides TPU infrastructure metrics in Cloud Monitoring, TPU logs, and error reports for better visibility and monitoring of TPU node pools in GKE clusters. TPUs are available with GKE Standard clusters. GKE supports TPU v4 in version 1.26.1.gke-1500 and later, and supports TPU v5e in version 1.27.2-gke.1500 and later. To learn more, see About TPUs in GKE.

You can now sequence the rollout of cluster upgrades across fleets or across scopes. To learn more, see About cluster upgrades with rollout sequencing.

August 28, 2023

Version 4.80.0 of the Terraform provider for Google Cloud fixes an issue observed when deploying new GKE Autopilot clusters that would destroy and re-create the cluster due to a change in the dns_config state. This version of the provider ensures that customers can deploy GKE Autopilot clusters using Cloud DNS as the default in-cluster DNS provider. For more information, see Terraform plans to re-create Autopilot cluster due to dns_config change.

August 25, 2023

GKE now delivers insights and recommendations to ensure your workloads are ready for disruption using features such as Pod Disruption Budgets. To learn more, see Ensure stateful workloads are disruption-ready.

You can now easily identify clusters that use deprecated Kubernetes APIs removed in versions 1.25, 1.26, and 1.27. Kubernetes deprecation insights are now available for these versions.

August 16, 2023

GKE Infrastructure Dashboards and Metrics Packages are now available for both GKE Autopilot and Standard clusters with control plane version 1.27.2-gke.1200 and later. You can now configure Autopilot or Standard clusters to export a predefined list of metrics emitted by GKE managed KSM (kube-state-metrics) for workloads state and Persistent Storage. These metrics are collected by Google Cloud Managed Service for Prometheus and are sent to Cloud Monitoring. You can also view new dashboards (Persistent and Workloads state) rendering those metrics in the Observability tab. For more information, see View observability metrics.

You can now troubleshoot issues with CPU limit utilization and Memory limit utilization of containers running in GKE by using the new "interactive playbook" dashboards in Cloud Monitoring.

August 10, 2023

Public clusters upgraded to GKE versions 1.24 and later will eventually be migrated to use Private Service Connect (PSC) for private control plane communication. After the control plane has been reconfigured, GKE schedules an update for your cluster's nodes to use the new private IP address to communicate with control plane. Each node pool is marked for recreation. You can use maintenance windows to control when your nodes are recreated. There is no price increase for using GKE public clusters running on PSC. For more information, see Public clusters with Private Service Connect.

August 09, 2023

The Filestore CSI driver now supports smaller share sizes (10Gi) for Filestore multishares for GKE for enterprise instances starting in version 1.27.

CVE-2023-0464, CVE-2023-0465, CVE-2023-0466, and CVE-2023-2650 have been patched in Filestore CSI driver in GKE versions 1.23 and 1.24, for newly created clusters.

Kubernetes control plane logs and Kubernetes control plane metrics are now available for GKE Autopilot clusters with control plane version 1.22.0 and later and 1.22.13 and later, respectively. You can now configure Autopilot cluster to export logs and certain metrics emitted by the Kubernetes API server, scheduler, and controller manager to Cloud Logging and Cloud Monitoring.

July 24, 2023

In new Autopilot clusters running GKE version 1.27 and later, GKE assigns IP addresses for GKE Services from a Google-managed range: 34.118.224.0/20 by default. With this feature, you don't need to specify your own IP address range for Services. For more information, see Subnet secondary IP address range for Services.

GKE Autopilot supports extended duration Pods from 1.27 or later with the cluster-autoscaler.kubernetes.io/safe-to-evict=false annotation. To learn more, see how to extend the run time of Autopilot Pods.

July 21, 2023

Update to the Issue release note published on July 19, 2023

We investigated this issue and are rolling back the --no-enable-insecure-kubelet-readonly-port flag in the gcloud CLI. New or existing clusters where the port is still enabled aren't affected. If you already disabled the port, your cluster will continue to work, but you may notice inconsistency in whether the port is fully disabled on every node of the cluster. We'll publish a release note if we have new updates related to the kubelet read-only port.

July 20, 2023

In GKE version 1.25 and later, there is a bug fix in the Ingress Controller to unset the Cloud Armor Ingress Security Policy when removed from the BackendConfig.

Users who have manually attached the Security Policy to a backend service should no longer use this method and should use the BackendConfig to continue using Cloud Armor Security Policies prior to cluster upgrades to GKE version 1.25 and later.

With this fix, the Ingress Controller will reconcile using the configuration in the BackendConfig, thus unsetting any Security Policies added manually to a backend service.

July 19, 2023

There's a known issue causing the gcloud CLI to crash when you run the command to disable the insecure kubelet read-only port, as described in Stop using the insecure kubelet read-only port in GKE clusters. We're investigating this issue and will publish an update when it's fixed.

Starting in GKE version 1.27 and gke-metrics-agent version 2.0.0, the memory request and limit of gke-metrics-agent will increase by an extra 60MiB. This change makes the system metrics collection more stable and reliable.

July 14, 2023

New Autopilot clusters created with version 1.27.3-gke.100 or later are now provisioned with e2-small default nodes, which are removed immediately after cluster creation. With this change, DaemonSets are guaranteed to schedule on all candidate nodes, as long as you follow best practices for DaemonSets on Autopilot.

July 13, 2023

The managed Cloud Storage FUSE CSI driver for GKE is now GA in versions 1.26.5 and later. You can use this driver to consume Cloud Storage buckets for GKE workloads.

July 12, 2023

GKE Dataplane V2 observability is now available in Public Preview starting in GKE versions 1.26.4-gke.500 or later, or 1.27.1-gke.400 or later. You can now enable Dataplane V2 metrics and observability tools on your cluster. Dataplane V2 metrics are included in new Autopilot clusters and opt-in for new Standard clusters. You can opt-in to enable Dataplane V2 observability tools for Autopilot and Standard clusters. Existing clusters can also be updated to enable metrics and observability tooling.

For more information, check out GKE Dataplane V2 observability.

Revision for the release note announced on June 26, 2023

Starting August 2023, Cloud DNS will become the default DNS provider for new GKE Autopilot clusters created with version 1.25.9-gke.400 or later, or version 1.26.4-gke.500 or later (effectively replacing kube-dns). The rollout will be gradual and expected to be completed by August 11, 2023. To learn more, see Cloud DNS for GKE.

In GKE version 1.24 and later, new beta APIs are, by default, disabled in new clusters. Starting in version 1.27, which is the first new minor version since 1.24 where new beta APIs are introduced, you can enable new APIs on cluster creation or for an existing cluster.

For more information, see how to Use Kubernetes beta APIs with GKE clusters.

July 11, 2023

You can now troubleshoot common GKE issues by using the new "interactive playbook" dashboards in Cloud Monitoring: unschedulable pods and crashlooping containers. You can also access the interactive playbooks from GKE UI insights and set alerts that will allow you to know once those issues occurs.

For information about using these dashboards, see the GKE troubleshooting documentation for unschedulable pods and crashlooping.

Starting in GKE version 1.27, cluster autoscaler always considers Compute Engine Reservations when making the scale-up decisions. The node pools with matching unused reservations are prioritized when choosing the node pool to scale up, even when the node pool is not the most efficient one. Additionally, unused reservations are always prioritized when balancing multi-zonal scale-ups.

For more information, see how to use cluster autoscaler.

July 10, 2023

The new release of the GKE Gateway controller (2023-R2) is now generally available. With this release, the GKE Gateway controller will provide the following new capabilities:

• New GatewayClasses supporting the regional external Application Load Balancer
• Identity-aware Proxy (IAP) Integration
• Custom request and response headers
• URL Rewrites and Path Redirects

To learn more, see the supported capabilities per GatewayClass.

GKE Autopilot now supports the ability to deploy your own service mesh. Many service meshes, such as Istio or LinkerD, require CAP_NET_ADMIN Linux capability to function, which is disabled on Autopilot clusters by default to reduce the size of the security attack surface. You can now optionally enable NET_ADMIN on your Autopilot clusters if you need this capability for your service meshes or other opt-in use cases. See Autopilot Security for more information for how to enable NET_ADMIN.

June 21, 2023

A new vulnerability, CVE-2023-0468, has been discovered in the Linux kernel that could allow an unprivileged user to escalate privileges to root when io_poll_get_ownership will keep increasing req->poll_refs on every io_poll_wake then overflow to 0 which will fput req->file twice and cause a struct file refcount issue. GKE clusters, including Autopilot clusters, with Container-Optimized OS using Linux Kernel version 5.15 are affected. GKE clusters using Ubuntu images or using GKE Sandbox are unaffected.

For instructions and more details, see the GKE security bulletin.

GKE support for Hyperdisk Throughput and Hyperdisk Extreme as an attached persistent disk option is now generally available. Support is available for both Autopilot and Standard clusters running GKE versions 1.26 and later.

You can now configure GKE clusters with control plane version 1.24 or later in Rapid channel to use a global external HTTP(S) load balancer to expose web services to the Internet, in a single cluster or multi-cluster architecture. You can benefit from many advanced traffic management capabilities offered by the new generation of Google Cloud global external HTTP(S) load balancers natively in GKE by using the Kubernetes Gateway API and specifying a new Gateway class. To see the difference between Gateway classes compatible with our GKE Gateway controller, see here.

Cloud DNS for GKE (cluster scope) is now Generally Available. You can now configure GKE clusters with control plane version 1.24.7-gke.800, 1.25.3-gke.700 or later to use Cloud DNS as the DNS provider for in-cluster name resolution, and replace the existing DNS service based on kube-dns.

10/06/2023 update: This migration is currently paused.

GKE Autopilot clusters may now migrate the cluster's datapath provider to Dataplane V2. Migration is triggered during a control plane upgrade (see version requirements below). The migration is complete once all nodes running the legacy datapath have been recreated. Node pools created after the control plane upgrade will be created using Dataplane V2.

• For clusters running 1.24 without Dataplane V2, upgrading to 1.24.7-gke.300 or a higher 1.24 version will begin the migration to Dataplane V2.

• For clusters running 1.25 without Dataplane V2, upgrading to 1.25.3-gke.200 or a higher 1.25 version will begin the migration to Dataplane V2.

To determine whether you are in the process of migrating the datapath, run:

gcloud container clusters describe <CLUSTER> --region <REGION> --project <PROJECT> --format="value(networkConfig.datapathProvider)"

Clusters migrating to Dataplane V2 will have the datapath provider field of the cluster set to MIGRATE_TO_ADVANCED_DATAPATH.

Clusters that have migrated to Dataplane V2 will have the datapath provider field of the cluster set to ADVANCED_DATAPATH.

December 13, 2022

Compact placement policy is now generally available. Set up a compact placement policy to specify that nodes within the node pool should be placed in closer physical proximity to each other within a zone. Having nodes closer to each other can reduce network latency between nodes, which can be useful for tightly-coupled batch workloads.

December 12, 2022

Public clusters upgraded to GKE versions 1.25 and later will eventually be migrated to use Private Service Connect (PSC) for private control plane communication. There is no price increase for using GKE public clusters running on PSC.

Kubernetes control plane logs are now Generally Available. You can now configure GKE clusters with control plane version 1.22.0 or later to export to Cloud Logging logs emitted by the Kubernetes API server, Scheduler, and Controller Manager.

These logs are stored in Cloud Logging and can be queried in the Cloud Logging Log Explorer or Cloud Logging API. These logs can also be sent to Google Cloud Storage, BigQuery, or Pub/Sub using the Log Router.

You can now use deprecation insights to identify clusters on versions 1.23 and earlier that use Docker-based node images, which are unsupported on GKE version 1.24 and later.

November 22, 2022

GKE version 1.21.14-gke.9500 has an issue where Pods in certain conditions might get stuck terminating indefinitely, due to a Linux kernel bug. The version has been removed and is no longer available for new clusters. If your node pools are running 1.21.14-gke.9500 and experience the issue, we recommend downgrading the node pool to 1.21.14-gke.8500.

November 21, 2022

The Logs tab available for each cluster on the Kubernetes Engine > Clusters page now includes suggested queries for your logs. For more information about using your GKE logs, see Viewing your GKE logs.

GKE Gateway for Single Cluster is now generally available in GKE version 1.24 and later. Use the Gateway API to express the intent of your inbound HTTP(S) traffic into your GKE cluster and the Gateway controller will instrument and fully manage the external and/or internal HTTP(S) load balancer(s) that forwards traffic to your applications. For complete details about the GKE Gateway controller, refer to the following documentation.

November 08, 2022

A security vulnerability, CVE-2022-39278, has been discovered in Istio, which is used in Anthos Service Mesh, that allows a malicious attacker to crash the control plane. GKE doesn't ship with Istio and isn't affected by this vulnerability. However, if you separately installed Anthos Service Mesh or Istio in your GKE cluster, refer to the Anthos Service Mesh security bulletin for more information.

November 07, 2022

When you create a LoadBalancer service in GKE, the Google Cloud controllers automatically create the following firewall rules and apply them to the GKE nodes to allow inbound connections on the Service port:

• Internal load balancer with GKE subsetting or external load balancer with regional backend services (RBS): k8s2-[cluster-id]-[namespace]-[service-name]-[suffixhash]
• Internal load balancer without GKE subsetting or external load balancer with target pool: k8s-fw-[loadbalancer-hash]

These rules now include the load balancer IP address in the destination ranges field to further control the inbound connections to the nodes. You can use the gcloud compute firewall-rules describe command to check a relevant firewall. The new field in the output is similar to the following:

destinationRanges:
- [LOADBALANCER_VIRTUAL_IP_ADDRESS]

On GKE Standard clusters using control plane version 1.24.2-gke.300 or later, you can configure the cluster and node pools to deploy an alternative version of the Logging agent designed to maximize logging throughput. The default Logging agent running in each GKE cluster guarantees at least 100 KB per second log throughput per node for system and workload logs. This Logging agent variant provides a 100x improvement, allowing for throughput as high as 10 MB per second on nodes that have at least 2 unused CPU cores.

Additionally, all GKE clusters with system metrics enabled now export a new metric (kubernetes.io/node/logs/input_bytes), which indicates the number of log bytes generated on a node. Using this metric can help you decide which variant of the logging agent makes sense to deploy in your cluster or node pools.

Newly created GKE Clusters on version 1.24 or later using Services without .spec.ports field defined will cause a crash-loop of the ingress-gce controller (l7lbcontroller pod). This will result in not being able to provide L7 Ingress, L4 Internal LoadBalancer Service with Subsetting turned on, and L4 Network LoadBalancer based on Regional Backend Services in the cluster.

To recover from this situation, delete the Service without a port specified or recreate the cluster without any Service with .spec.ports undefined.

A new vulnerability (CVE-2022-1786) has been discovered in the Linux kernel versions 5.10 and 5.11. This vulnerability allows an unprivileged user with local access to the cluster to achieve a full container breakout to root on the node. Only clusters that run Container-Optimized OS are affected. GKE Ubuntu versions use either version 5.4 or 5.15 of the kernel and are not affected. For more information, refer to the GCP-2022-017 security bulletin.

GKE Cost Allocation has been released for public preview. With GKE Cost Allocation public preview, you will be able to see cost breakdowns in clusters for namespaces, and pod labels for utilized CPU and MEM. For complete details, refer to View detailed breakdown of cluster costs.

To deliver a better default price-performance for applications, all GKE clusters created with control plane version 1.24 and later have the Balanced Persistent Disk (PD) by default for attached volumes. Additionally, the node boot disk default has also been changed to Balanced Persistent Disk (PD).

The new default for attached volumes is applied to all clusters running control plane version 1.24 and later. The new default node boot disk is applied to all new node pools of any node pool version created in a cluster with control plane version 1.24 and later. Existing preferences will not be changed.

For more information on boot disks, see Configuring a custom boot disk.

For more information on attached volumes see Persistent volumes and dynamic provisioning.

New API versions

• storage.k8s.io/v1 CSIStorageCapacity

Notable changes

• GKE does not support node images that use Docker as the runtime in GKE version 1.24 and later. For more information, see migrating from Docker to containerd.
• Secret API objects containing service account tokens are not automatically created in 1.24.
  • This change improves security by reducing readable, permanent, Secret-based tokens to ones that have been explicitly requested, and improves performance by reducing the amount of persisted Secret data and avoiding unnecessary utilization of application-layer secrets encryption.
  • Existing Secret-based tokens from previous versions remain valid on upgrade.
  • Secret-based tokens are not used by nodes or pods on version 1.21 and later.
  • Only node versions 1.22 and later are supported running against 1.24 clusters.
  • Clients retrieving tokens directly from the API can still obtain a token using these methods supported in all available GKE versions:
    • Preferred: Use the TokenRequest API to obtain time-bound tokens that are not readable by other API clients. The kubectl create token command is available in kubectl 1.24+ to simplify use of this API from the command line.
    • Secret-based tokens can still be obtained by creating a Secret object and waiting for it to be populated with a token.
  • Examples of incorrect ways to obtain Secret-based tokens from the API include:
    • Scanning the secrets[*].name field of a ServiceAccount object; this field lists secrets usable by pods running as that service account, not for other purposes, and secrets in that list have never been guaranteed to be service account token secrets.
    • Looking for existing Secret objects of type kubernetes.io/service-account-token created by other clients; a Secret created by another client is owned by that client, and cannot be assumed to be stable for use by other clients.

• Kubernetes 1.24 deprecates support for insecure serving certificates signed with a SHA-1 hash. Aggregated API servers, admission webhooks, and custom resource conversion webhooks using TLS certificates that are signed by SHA-1 should replace the serving certificates as soon as possible.

  • At cluster version 1.24.0 and later, GKE provides a Cloud Audit log to check if your cluster contains an affected service. You can use the following filter to search for the logs of a 1.24+ cluster:

    logName: "projects/$PROJECT/logs/cloudaudit.googleapis.com%2Factivity"
    resource.type = "k8s_cluster"
    operation.producer = "k8s.io"
    "invalid-cert.kubernetes.io"
    ```
    

  • If you are not affected you won't see any logs. If you do see such an audit log, it will include the name of the service (whether webhook or aggregated API).

Deprecated API versions

These APIs are still served in version 1.24 but are in a deprecation period:

• PodSecurityPolicy

  • policy/v1beta1 PodSecurityPolicy
  • Deprecated in 1.21 with removal targeted for version 1.25.
  • 1.24 is the last version supporting the beta PodSecurityPolicy feature. Use of this feature must be discontinued before clusters will upgrade to 1.25. For more information, see PodSecurityPolicy deprecation.

• The following Beta versions of graduated APIs will be removed in 1.25 in favor of their newer versions:

  • discovery.k8s.io/v1beta1 EndpointSlice, deprecated since 1.21
  • policy/v1beta1 PodDisruptionBudget, deprecated since 1.21
  • batch/v1beta1 CronJob, deprecated since 1.21
  • node.k8s.io/v1beta1 RuntimeClass
  • autoscaling/v2beta1 HorizontalPodAutoscaler

• The following Beta versions of graduated APIs will be removed in 1.26 in favor of newer versions:

  • flowcontrol.apiserver.k8s.io/v1beta1 FlowSchema, PriorityLevelConfiguration
    • deprecated since 1.23
    • use flowcontrol.apiserver.k8s.io/v1beta2 instead, available since 1.23
  • autoscaling/v2beta2 HorizontalPodAutoscaler
    • deprecated since 1.23
    • use autoscaling/v2 instead, available since 1.23 (or autoscaling/v1)

• The following Beta versions of graduated APIs will be removed in 1.27 in favor of new versions:

  • storage.k8s.io/v1beta1 CSIStorageCapacity, deprecated since 1.24

Nodes on version 1.24.0-gke.1000 with more than 80GB of memory will fail to start successfully due to a known bug, which will be resolved in future 1.24 versions.

May 25, 2022

You can now easily assess the running cost implications at cluster creation time. The GKE cluster cost widget lets you get an estimated cost range when you are creating a cluster.

This information can help you get a better understanding of the upper and lower monthly cost to expect based on your cluster autoscaling setup. This feature is now available in Preview.

For more information, see Introducing GKE cost estimator, built right into the Google Cloud console.

GKE clusters that run control plane versions 1.21 or later and node versions 1.16 or earlier might experience:

• Readiness check failures.
• Network endpoint groups (NEGs) and load balancers (LBs) not created or synced.

This occurs because the Ingress controllers running in GKE cluster control plane versions 1.21 or later are not compatible with node versions 1.16 and earlier. To resolve this issue, upgrade your node pools.

For more information, see Node version not compatible with control plane version.

May 24, 2022

The us-east5 region in Columbus, Ohio is now available.

May 20, 2022

You can now quickly identify which of your workloads are underutilized in the Cost Optimization tab. You can also quickly apply suggested values for resource requests and limits (or your own preferred values).

This feature is now available in Preview. For more information, see GKE workload rightsizing.

April 13, 2022

A security vulnerability, CVE-2022-23648, has been discovered in containerd's handling of path traversal in the OCI image volume specification. Containers launched through containerd's CRI implementation with a specially-crafted image configuration could gain full read access to arbitrary files and directories on the host. This vulnerability may bypass any policy-based enforcement on container setup (including a Kubernetes Pod Security Policy). This vulnerability affects all GKE node operating systems (Container-Optimized OS and Ubuntu) which use containerd by default. All GKE, Autopilot, and GKE Sandbox nodes are affected.

For more information, see the GCP-2022-013 security bulletin.

Egress NAT policy to configure IP masquerade is now generally available on GKE Autopilot clusters with Dataplane v2 in versions 1.22.7-gke.1500+ or 1.23.4-gke.1600+. For configuration examples of Egress NAT policy, see Egress NAT Policy documentation.

Versions 1.21.9-gke.300, 1.22.6-gke.300, and 1.23.2-gke.300 contain a fix for a race condition which could result in erroneously detaching all endpoints from network endpoint groups for a short period.

February 04, 2022

A security vulnerability, CVE-2021-4034, has been discovered in pkexec, a part of the Linux policy kit package (polkit), that allows an authenticated user to perform a privilege escalation attack. PolicyKit is generally used only on Linux desktop systems to allow non-root users to perform actions such as rebooting the system, installing packages, restarting services etc, as governed by a policy. GKE clusters are not affected.

For instructions and more details, see the GCP-2022-004 security bulletin.

You will not be able to create new node pools that use a Docker node image starting with GKE v1.23 when:

• Creating a new cluster,
• Adding a node pool to an existing cluster, or
• Using Node Auto-provisioning (NAP) with --autoprovisioning-image-type set to Docker node images.
• For existing clusters, you will also not be able to change the value of --autoprovisioning-image-type to Docker node images.

If you are upgrading your GKE clusters from GKE v1.22 to v1.23, then you will be able to continue using:

• Docker node pools that were configured before the upgrade.
• Cluster Autoscaler on Docker node pools.
• Node Auto-provisioning (NAP) with --autoprovisioning-image-type set to Docker node images if it was configured before upgrading to v1.23. However, we highly recommend you to migrate to GKE node images that use the Containerd container runtime.

For your reference, below are the GKE node images for the Containerd and Docker container runtimes:

• Containerd container runtime (recommended): cos_containerd, ubuntu_containerd, windows_ltsc_containerd, windows_sac_containerd
• Docker container runtime (unsupported starting with v1.24): cos, ubuntu, windows_ltsc, windows_sac

Containerd is the default runtime on GKE. Most user workloads do not have dependencies on the container runtime. Support for Docker as a container runtime on Kubernetes nodes will be removed from OSS Kubernetes and GKE starting with v1.24. If you use a node image based on Docker container runtime, please migrate your GKE workloads to a Containerd node image as soon as possible. For more details, see Containerd node images.

Three security vulnerabilities, CVE-2021-4154, CVE-2021-22600, and CVE-2022-0185 have been discovered in the Linux kernel, each of which can lead to either a container breakout, privilege escalation on the host, or both. These vulnerabilities affect all GKE node operating systems and Anthos clusters on VMware node operating systems (COS and Ubuntu).

Pods using GKE Sandbox are not vulnerable to these vulnerabilities. For more information, see the GCP-2022-002 security bulletin.

January 31, 2022

In GKE, you can now filter Pub/Sub cluster notifications by notification type. For more information, see Receive cluster notifications.

When creating a maintenance exclusion window, you can restrict the exclusion to specify types of maintenance. For example, during a specific time period you can exclude minor upgrades from occurring on your cluster. For more information, see Maintenance exclusions documentation.

January 27, 2022

Starting with GKE version 1.23.0, if a Kubernetes event is created using k8s.io/api/core/v1, the LastTimestamp field is used as the timestamp of the corresponding event log if the field is non-empty. Otherwise, the timestamp field will be unset and will be determined by Cloud Logging.

If a Kubernetes event is created using k8s.io/api/events/v1, the Series.LastObservedTime field is used as the timestamp of the corresponding event log if the field is non-empty. Otherwise, the timestamp field will be unset and will be determined by Cloud Logging. An event created with k8s.io/api/events/v1 will be converted to k8s.io/api/core/v1 before exporting to Cloud Logging.

Log payload of an event log will contain the LastTimestamp field from k8s.io/api/core/v1 Event API. If an event is created using k8s.io/api/events/v1, the value of this field will be null. Instead, use the Series.LastObservedTime field in the log payload.

1.23 is now available in the Rapid channel

Kubernetes 1.23 is now available in the Rapid channel. Before upgrading, read the Kubernetes 1.23 Release Notes, especially the action required and deprecation sections.

Notable features

Beta: PodSecurity admission

PodSecurity replaces the deprecated PodSecurityPolicy admission controller (which will be removed in 1.25). PodSecurity is an admission controller that enforces Pod Security Standards on Pods in a Namespace based on specific namespace labels that set the enforcement level. In 1.23, the PodSecurity feature is enabled by default, and applies to namespaces that opt into enforcement. Refer to the PodSecurity documentation and PodSecurityPolicy migration guide for more information.

Notable changes and bug fixes

Kubernetes 1.23 is built with go1.17, which requires aggregated API servers, admission webhooks, and custom resource conversion webhooks to use TLS certificates that include the service DNS name as a subjectAltName.

• Before upgrading to 1.23, ensure any non-local aggregated API servers, admission webhooks, and custom resource conversion webhooks in your cluster are served using valid TLS certificates.

• At cluster version 1.22.3-gke.700 or higher, GKE provides a Cloud Audit log to check if your cluster contains an affected service. You can use the following filter to search for the logs:

  logName: "projects/$PROJECT/logs/cloudaudit.googleapis.com%2Factivity"
  resource.type = "k8s_cluster"
  operation.producer = "k8s.io"
  "invalid-cert.webhook.gke.io"
  

• If you are not affected you won't see any logs. If you do see such an audit log, it will include the name of the service (whether webhook or aggregated API).

New API versions

• flowcontrol.apiserver.k8s.io/v1beta2 FlowSchema, PriorityLevelConfiguration
• autoscaling/v2 HorizontalPodAutoscaler

Deprecated API versions

These APIs are still served in version 1.23 but are in a deprecation period:

• PodSecurityPolicy
  • policy/v1beta1 PodSecurityPolicy
  • Deprecated in 1.21 with removal targeted for version 1.25.
• The following Beta versions of graduated APIs will be removed in 1.25 in favor of their GA versions:
  • discovery.k8s.io/v1beta1 EndpointSlice, deprecated since 1.21
  • policy/v1beta1 PodDisruptionBudget, deprecated since 1.21
  • batch/v1beta1 CronJob, deprecated since 1.21
  • node.k8s.io/v1beta RuntimeClass
  • autoscaling/v2beta1 HorizontalPodAutoscaler
• The following Beta versions of graduated APIs will be removed in 1.26 in favor of newer versions:
  • flowcontrol.apiserver.k8s.io/v1beta1 FlowSchema, PriorityLevelConfiguration
    • deprecated since 1.23
    • use flowcontrol.apiserver.k8s.io/v1beta2 instead, available since 1.23
  • autoscaling/v2beta2 HorizontalPodAutoscaler
    • deprecated since 1.23
  • use autoscaling/v2 instead, available since 1.23 (or autoscaling/v1)

Clusters running GKE node versions 1.19.16-gke.1500 and 1.19.16-gke.3600 will be unstable if Container Threat Detection (KTD) is enabled. To use KTD, create the cluster with the most recent 1.19.15 version or any GKE version 1.20 or later. If you require GKE version 1.19.16-gke.1500 or 1.19.16-gke.3600, you should disable KTD on the cluster using the Cloud Security Command Center Advanced Settings before creating or upgrading nodes to these versions

January 20, 2022

VPC-scoped DNS for GKE using Cloud DNS is now generally available for GKE versions 1.21 and later. This allows for seamless VPC-wide DNS resolution of GKE Services. Note that cluster-scoped DNS using Cloud DNS is still in public preview.

A new kubernetes metric, Network policy event count (kubernetes.io/pod/network/policy_event_count), is available (beta) for GKE Dataplane V2 clusters in GKE versions 1.22.3-gke.700 and later.

This metric can be viewed in the Metrics Explorer in Cloud Monitoring for resource type, Kubernetes Pod.

This metric provides visibility into network policy events and shows the Change in the number of network policy events seen in the dataplane, each event has the following metric labels:

• verdict: Policy verdict, possible values: [allow, deny].
• workload_kind: Kind of the workload, policy-enforced-pod belongs to, for example, "Deployment", "Replicaset", "StatefulSet", "DaemonSet", "Job", or "CronJob".
• workload_name: Name of the workload, policy-enforced-pod belongs to.
• direction: Direction of the traffic from the point of view of policy-enforced-pod, possible values: [ingress, egress].

In addition to these metric labels, customers can also see usual resource labels for resource type, Kubernetes Pod: project_id, location, cluster_name, namespace_name, and pod_name.

This metric can be used for setting up automated alerts for specific behaviors (denials higher than a threshold), identifying security issues, gaining better understanding of traffic flow, and troubleshooting.

January 17, 2022

Now available in Preview: Use a compact placement policy to specify that nodes within the node pool should be placed in closer physical proximity to each other within a zone. Having nodes closer to each other can reduce network latency between nodes, which can be useful for tightly-coupled batch workloads.

December 20, 2021

For GKE versions 1.21 and later, newly created clusters will have the DenyServiceExternalIPs admission controller enabled by default, disabling the use of ExternalIPs Services.

For existing clusters, when you upgrade the cluster to GKE version 1.21 or later, the DenyServiceExternalIPs admission controller will not be enabled. Since ExternalIPs Services are not widely used, we recommend manually auditing any external IP usage. You can choose to block ExternalIPs by using the following command:

gcloud container clusters update --no-enable-service-externalips

For more information, refer to Hardening your cluster's security.

A bug was found in containerd where container root directories and some plugins had insufficiently restricted permissions, allowing otherwise unprivileged Linux users to traverse directory contents and execute programs.

This issue is fixed in the following GKE versions:

• 1.22.3-gke.1100 or above
• 1.21.6-gke.700 or above
• 1.20.12-gke.700 or above
• 1.19.16-gke.700 or above

For more information about the CVE, refer to CVE-2021-41103.

December 14, 2021

File capability CAP_NET_BIND_SERVICE required by metrics-server to bind privileged port 443 is dropped in clusters that enable PodSecurityPolicy and use the Ubuntu with Docker container runtime in node pools. As a result, metrics-server fails to bootstrap and autoscaling functionality fails to function. All 1.21 and 1.22 node versions are impacted. This issue will be fixed in a future release. Automatic node upgrades from GKE version 1.20 to 1.21 will be halted until this issue is fixed.

December 09, 2021

GKE version 1.22.3-gke.1500 and later support user impersonation for all user-defined users and groups. System users and groups such as the kube-apiserver user and the system:masters group cannot be impersonated.

GKE public clusters versions 1.22 and later created on or after October 28, 2021, will move to using Private Service Connect (PSC) for private control plane communication. There is no price increase for using GKE public clusters running on PSC, however, there will be a SKU change. This change does not apply to public clusters using legacy networks.

In clusters running GKE version 1.21.0-gke.1000 and later, the destination IP address and port of the GKE metadata server has changed. If you have a cluster network policy and you use Workload Identity, you should update your network policy to allow access to the following destination IP addresses and ports. To avoid disruptions during auto-upgrades, allow access to all these destination address and destination port combinations in your network policy. For more information, see Understanding the GKE metadata server.

GKE version	GKE metadata server address
Prior to 1.21.0-gke.1000	127.0.0.1:987 and 127.0.0.1:988
1.21.0-gke.1000 and later	169.254.169.252:987 and 169.254.169.252:988

October 27, 2021

In GKE version 1.22 and later, GKE cluster autoscaler and node auto-provisioning will support working on empty (zero node) clusters, and will support scaling down nodes with pods requesting local storage.

October 21, 2021

1.21 is now generally available

Kubernetes version 1.21 is now generally available. Before upgrading, read the Kubernetes 1.21 Release Notes, especially the action required and deprecation sections.

The following features are introduced in version 1.21:

CronJob (GA)

The CronJob API has graduated to General Availability (GA), bringing performance improvements and allowing scheduled jobs to be run using a stable API.

• This resource is now available in the batch/v1 group/version.
• The batch/v1beta1 group/version is deprecated, and will be removed in version 1.25. See the migration guide for details.

PodDisruptionBudget (GA)

The PodDisruptionBudget has graduated to GA, allowing Pod evictions to be controlled using a stable API.

• This resource is now available in the policy/v1 group/version.
• The policy/v1beta1 group/version is deprecated, and will be removed in version 1.25. See the migration guide for details.

EndpointSlice (GA)

The EndpointSlice API has graduated to GA, bringing performance improvements over the v1 Endpoints API.

• This more scalable API for service discovery is now enabled on all clusters and is promoted to discovery.k8s.io/v1.
• The discovery.k8s.io/v1beta1 group/version is deprecated, and will be removed in version 1.25. See the migration guide for details.

Default namespace label (Beta)

Namespace API objects now have a kubernetes.io/metadata.name label matching their metadata.name field to allow selecting any namespace by its name using a label selector. This can be used for objects which select namespaces by label, such as admission webhooks and network policies.

Bound service account token volumes (Beta)

• The API credentials injected into containers at /var/run/secrets/kubernetes.io/serviceaccount/token are now time-limited, auto-refreshed, and invalidated when the containing pod is deleted.
• By default, injected tokens are given an extended lifetime so they remain valid even after a new refreshed token is provided. The metric serviceaccount_stale_tokens_total and the audit annotation authentication.k8s.io/stale-token can be used to monitor for workloads that depend on the extended lifetime and are continuing to use tokens even after a refreshed token is provided to the container.
• Clients should reload the token from disk periodically (once per minute is recommended) to ensure they use the refreshed token. k8s.io/client-go version 11.0.0+ and 0.15.0+ reload tokens automatically.

In Kubernetes 1.21, newly provisioned PersistentVolumes by gce-pd will use the topology.kubernetes.io/zone GA label instead of the failure-domain.beta.kubernetes.io/zone beta label.

Notable changes and bug fixes in 1.22

• The terminationGracePeriodSeconds field on pod specs and container probes should not be negative. Negative values of terminationGracePeriodSeconds will be treated as the value 1 on the delete path. Immutable field validation will be relaxed in order to update negative values. In a future release, negative values will not be permitted. (#98866)

• As a mitigation for CVE-2021-25740, newly created Kubernetes 1.22 clusters no longer include write access to the Endpoints API in the edit and admin roles by default. Existing clusters upgraded to Kubernetes 1.22 retain previous permissions in those roles. For instructions to re-add Endpoints write access to the edit and admin roles in newly created 1.22 clusters, refer to the RBAC documentation.

If you manually upgrade your cluster from 1.18 to 1.19 and the network tier configuration on an existing external network load balancer does not match the network tier annotation in the service spec (if unspecified, defaults to Premium), the load balancer will be deleted and recreated, and the network tier configuration will be enforced.

A domain-scoped project is not supported in GKE version 1.20. The cluster's CertificateSigningRequest will be denied when validating the DNS name and the nodes cannot join the cluster.

1.20 is now generally available

Kubernetes 1.20 is now generally available (GA). Before upgrading, read the Kubernetes 1.20 Release Notes especially the Urgent upgrade notes and Deprecations sections.

The node.k8s.io/v1beta1 RuntimeClass API has graduated to node.k8s.io/v1 with no changes. API clients and manifests should switch to using the node.k8s.io/v1 API after version 1.20. The node.k8s.io/v1beta1 API is deprecated and will no longer be served starting in version 1.25.

As of version 1.20, the kubelet no longer creates the target_path for NodePublishVolume in accordance with the CSI spec. If you have self-managed CSI drivers deployed in your cluster, ensure that they are idempotent and do any necessary mount creation or verification. For more information, see Kubernetes issue #88759.

Starting in version 1.20, timeouts on exec probes are honored, and default to 1 second if unspecified. If you have Pods using exec probes, ensure that they can easily complete in 1 second or explicitly set an appropriate timeout. For more information, see ConfigureProbes.

Non-deterministic treatment of objects with invalid ownerReferences was fixed in version 1.20. Run the kubectl-check-ownerreferences tool prior to upgrade to locate existing objects with invalid ownerReferences.

• A namespaced object with an ownerReference to another namespaced object which does not exist in the same namespace is now consistently treated as having a missing owner and is deleted.

• A cluster-scoped object with an ownerReference to a namespaced object is now consistently treated as having an unresolvable owner, and is ignored by the garbage collector.

• Starting in version 1.20, when a namespace mismatch between a child and owner object is detected, an event with a reason code of OwnerRefInvalidNamespace is recorded.

The metadata.selfLink field, deprecated since version 1.16, is no longer populated in version 1.20. See Kubernetes issue #1164 for details. A related bug in the k8s.io/client-golibrary in the GetReference function was fixed in versions 0.15.9 or later, 0.16.4 or later, and 0.17.0 or later. Clients using the GetReference function should upgrade to one of those versions of client-go or newer in order to work correctly against an API Server running version 1.20 or later.

Reminder: Future beta API removals in versions 1.22 and 1.25

Kubernetes versions 1.22 and 1.25 will stop serving several deprecated beta APIs. It is recommended to begin migrating your clients and manifests to the stable replacement APIs now. More information is available in the OSS Kubernetes documentation.

June 07, 2021

You can now specify the default image type to use for new auto-provisioning node pools. See Using node auto-provisioning for more details.

1.21 available in the Rapid channel

Kubernetes version 1.21 is now available in the Rapid channel. Before upgrading, read the Kubernetes 1.21 Release Notes, especially the action required and deprecation sections.

1.21 Features

The following features are introduced in version 1.21:

CronJob (GA)

The CronJob API has graduated to General Availability (GA), bringing performance improvements and allowing scheduled jobs to be run using a stable API.

• This resource is now available in the batch/v1 group/version.
• The batch/v1beta1 group/version is deprecated, and will be removed in version 1.25. See the migration guide for details.

PodDisruptionBudget (GA)

The PodDisruptionBudget has graduated to GA, allowing pod evictions to be controlled using a stable API.

• This resource is now available in the policy/v1 group/version.
• The policy/v1beta1 group/version is deprecated, and will be removed in version 1.25. See the migration guide for details.

EndpointSlice (GA)

The EndpointSlice API has graduated to GA, bringing performance improvements over the v1 Endpoints API.

• This more scalable API for service discovery is now enabled on all clusters and is promoted to discovery.k8s.io/v1.
• The discovery.k8s.io/v1beta1 group/version is deprecated, and will be removed in version 1.25. See the migration guide for details.

Default namespace label (Beta)

Namespace API objects now have a kubernetes.io/metadata.name label matching their metadata.name field to allow selecting any namespace by its name using a label selector. This can be used for objects which select namespaces by label, such as admission webhooks and network policies.

Bound service account token volumes (Beta)

• The API credentials injected into containers at /var/run/secrets/kubernetes.io/serviceaccount/token are now time-limited, auto-refreshed, and invalidated when the containing pod is deleted.
• By default, injected tokens are given an extended lifetime so they remain valid even after a new refreshed token is provided. The metric serviceaccount_stale_tokens_total and the audit annotation authentication.k8s.io/stale-token can be used to monitor for workloads that depend on the extended lifetime and are continuing to use tokens even after a refreshed token is provided to the container.
• Clients should reload the token from disk periodically (once per minute is recommended) to ensure they use the refreshed token. k8s.io/client-go version 11.0.0+ and 0.15.0+ reload tokens automatically.

In Kubernetes 1.21, newly provisioned PersistentVolumes by gce-pd will use the topology.kubernetes.io/zone GA label instead of the failure-domain.beta.kubernetes.io/zone beta label.

1.21 New Beta and Stable APIs

The following Stable APIs are new in 1.21:

• batch/v1 CronJob
• policy/v1 PodDisruptionBudget
• discovery.k8s.io/v1 EndpointSlice

The following Beta APIs are new in 1.21:

• storage.k8s.io/v1beta1 CSIStorageCapacity

1.21 Deprecated APIs

The following APIs are deprecated in the 1.21 release:

• PodSecurityPolicy
  • policy/v1beta1 PodSecurityPolicy
  • Deprecated in 1.21 with removal targeted for version 1.25.

  • policy/v1beta1 PodDisruptionBudget
  • batch/v1beta1 CronJob
• The following Beta versions of previously graduated APIs will be removed in 1.22 in favor of GA versions:

1.19 GA

GKE version 1.19 is now generally available (GA).

Before upgrading to 1.19, read the Kubernetes 1.19 Release Notes especially the Urgent upgrade notes.

See below for notable changes and features in version 1.19.

The basic authentication method is no longer available starting with Kubernetes version 1.19. GKE clusters also no longer support basic authentication as they gradually upgrade to Kubernetes version 1.19. Basic authentication has been disabled by default for new GKE clusters since GKE version 1.12 and its usage has been discouraged in the Hardening your cluster's security guide. Migrate away from basic authentication before your cluster control planes are upgraded to Kubernetes version 1.19 to ensure your API clients can continue accessing the API server. To learn more about recommended authentication methods in GKE, see Authenticating to the Kubernetes API Server.

Admission webhooks and custom resource conversion webhooks must use serving certificates that contain the server name in a subjectAltName extension. Server names in the certificate CommonName will not be honored in future versions.

kube-proxy now uses EndpointSlices by default.

With the release of GKE node version 1.19, the Container-Optimized OS with Docker (cos) variant is deprecated. Please migrate to the Container-Optimized OS with Containerd (cos_containerd) variant, which is now the default GKE node image. For instructions, see Containerd images.

Seccomp General Availability (GA)

Seccomp (secure computing mode) support for Kubernetes has graduated to General Availability (GA). This feature can be used to increase the workload security by restricting the system calls for a Pod (applies to all containers) or individual containers.

A new seccompProfile field is added to Pod and Container securityContext objects, starting in Kubernetes version 1.19.

securityContext:
  seccompProfile:
    # "Unconfined", "RuntimeDefault", or "Localhost"
    type: Localhost
    # only necessary if type == Localhost
    localhostProfile: my-profiles/profile-allow.json

The alpha seccomp annotations seccomp.security.alpha.kubernetes.io/pod and container.seccomp.security.alpha.kubernetes.io/... are deprecated in favor of the GA API field. The alpha annotations will not be honored in Kubernetes versions 1.22 and later.

Prepare for transition

If you are currently using Seccomp annotations on Pods or Containers, you should identify and transition workloads using the annotations to set the API fields before version 1.21 is released on GKE (approximately in June 2021). No change on PodSecurityPolicy is required, as it supports both annotation and field seccomp profiles. You can perform the following recommended steps:

Locate Seccomp annotation usages

In your Kubernetes manifest files, search for "seccomp.security.alpha.kubernetes.io/pod" and "container.seccomp.security.alpha.kubernetes.io/".

Add or update securityContext fields

Based on your annotation usage, add or update (if securityContext already exists) the securityContext field in the Pod or Container spec. The annotations can be left in place, but must match the securityContext API field.

Current annotation usage	Add or update securityContext
seccomp.security.alpha.kubernetes.io/pod	In the Pod's securityContext, add the seccompProfile field.
container.seccomp.security.alpha.kubernetes.io/container-name	In the container-name container's securityContext, add the seccompProfile field.

Set values for seccompProfile

The type field of seccompProfile corresponds to the annotation value, and localhostProfile field corresponds to the path following localhost annotation value.

Current annotation value	seccompProfile value
unconfined	seccompProfile: type: Unconfined
runtime/default or docker/default	seccompProfile: type: RuntimeDefault
localhost/path/to/profile.json	seccompProfile: type: Localhost localhostProfile: path/to/profile.json

The widely used Ingress API has graduated to general availability in Kubernetes 1.19. The v1beta1 Ingress API is deprecated, and will no longer be served in versions 1.22 and later. Before version 1.21, identify and transition clients and manifests using the v1beta1 Ingress API to use networking.k8s.io/v1.

Clusters with Google Cloud's operations suite enabled can use the following query to identify clients that access the Ingress v1beta1 APIs:

resource.type="k8s_cluster"
resource.labels.cluster_name="$CLUSTER_NAME"
protoPayload.authenticationInfo.principalEmail:("system:serviceaccount" OR "@")
protoPayload.request.apiVersion=("extensions/v1beta1" OR "networking.k8s.io/v1beta1")
protoPayload.request.kind="Ingress"
NOT ("kube-system")

Identify and transition clients and manifests using the v1beta1 Ingress APIs to use networking.k8s.io/v1 before version 1.21 is released on GKE (approximately in June 2021), then verify no clients are using the v1beta1 API during the version 1.21 timeframe. Workloads using the v1beta1 APIs need to be upgraded before your cluster is upgraded to GKE 1.22.

To migrate manifests to networking.k8s.io/v1, perform the following:

1. Rename the spec.backend field (if specified) to spec.defaultBackend.
2. Rename each backend.serviceName field to backend.service.name.
3. Rename each numeric backend.servicePort field to backend.service.port.number.
4. Rename each string backend.servicePort field to backend.service.port.name.
5. Specify a pathType field for each defined path. Options are Prefix, Exact, and ImplementationSpecific. To match the undefined v1beta1 behavior, use ImplementationSpecific.

As an example, to migrate this v1beta1 manifest to v1:

Original v1beta1 manifest	Equivalent networking.k8s.io/v1 manifest
apiVersion: networking.k8s.io/v1beta1 kind: Ingress metadata: name: example spec: backend: serviceName: default-backend servicePort: 80 rules: - http: paths: - path: /testpath backend: serviceName: test servicePort: 80	apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: example spec: defaultBackend: service: name: default-backend port: number: 80 rules: - http: paths: - path: /testpath pathType: ImplementationSpecific backend: service: name: test port: number: 80

CertificateSigningRequest v1 API

The CertificateSigningRequest API has graduated to certificates.k8s.io/v1 in Kubernetes 1.19. The v1beta1 CertificateSigningRequest API is deprecated and will no longer be served in version 1.22 and later.

Clusters with Google Cloud's operations suite enabled can use the following query to identify clients that access the CertificateSigningRequest v1beta1 APIs:

resource.type="k8s_cluster"
resource.labels.cluster_name="$CLUSTER_NAME"
protoPayload.authenticationInfo.principalEmail:("system:serviceaccount" OR "@")
protoPayload.request.apiVersion="certificates.k8s.io/v1beta1"
NOT ("kube-system")

Identify and transition clients and manifests using the v1beta1 CertificateSigningRequest API to use certificates.k8s.io/v1 before version 1.21 is released on GKE (approximately in June 2021), then verify no clients are using the v1beta1 API during the version 1.21 timeframe. Workloads using the v1beta1 API need to be upgraded before your cluster is upgraded to GKE version 1.22.

Differences between the v1beta1 and v1 API are as follows:

• For API clients requesting certificates:
  • spec.signerName is now required, and requests for kubernetes.io/legacy-unknown are not allowed to be created via the certificates.k8s.io/v1 API.
  • spec.usages is now required, may not contain duplicate values, and must only contain known usages.
• For API clients approving or signing certificates:
  • status.conditions may not contain duplicate types.
  • status.conditions[*].status is now required.
  • status.certificate must be PEM-encoded, and must contain only CERTIFICATE blocks.

Admission webhooks and custom resource conversion webhooks using invalid serving certificates that do not contain the server name in a subjectAltName extension cannot be contacted by the Kubernetes API server in 1.19 prior to version 1.19.9-gke.400. This will be resolved in version 1.19.9-gke.400, and automatic upgrades from 1.18 to 1.19 will not begin until this issue is resolved. However, affected webhooks should work to correct their serving certificates in order to work correctly with Kubernetes version 1.22 and later.

Service API objects with more than 100 ports do not work correctly with EndpointSlices (https://issue.k8s.io/99382). This will be resolved in version 1.19.9-gke.600, and automatic upgrades from 1.18 to 1.19 will not begin until this issue is resolved.

1.20 available in the Rapid channel

Kubernetes 1.20 is now available in the Rapid channel. Before upgrading to 1.20.2-gke.2500, read the Kubernetes 1.20 ReleaseNotes especially the Urgent upgrade notes and Deprecations sections.

RuntimeClass graduated to GA in version 1.20: The node.k8s.io/v1beta1 RuntimeClass API has graduated to node.k8s.io/v1 with no changes. API clients and manifests should switch to using the node.k8s.io/v1 API after version 1.20. The node.k8s.io/v1beta1 API is deprecated and will no longer be served starting in version 1.25.

As of version 1.20, the kubelet no longer creates the target_path for NodePublishVolume in accordance with the CSI spec. If you have self-managed CSI drivers deployed in your cluster, ensure that they are idempotent and do any necessary mount creation or verification. For more information, see Kubernetes issue #88759.

Starting in version 1.20, timeouts on exec probes are honored, and default to 1 second if unspecified. If you have Pods using exec probes, ensure that they can easily complete in 1 second or explicitly set an appropriate timeout. For more information, see ConfigureProbes.

Non-deterministic treatment of objects with invalid ownerReferences was fixed in version 1.20. Run the kubectl-check-ownerreferences tool prior to upgrade to locate existing objects with invalid ownerReferences.

• A namespaced object with an ownerReference to another namespaced object which does not exist in the same namespace is now consistently treated as having a missing owner and is deleted.

• A cluster-scoped object with an ownerReference to a namespaced object is now consistently treated as having an unresolvable owner, and is ignored by the garbage collector.

• Starting in version 1.20, when a namespace mismatch between a child and owner object is detected, an event with a reason code of OwnerRefInvalidNamespace is recorded.

The metadata.selfLink field, deprecated since version 1.16, is no longer populated in version 1.20. See Kubernetes issue #1164 for details. A related bug in the k8s.io/client-golibrary in the GetReference function was fixed in versions 0.15.9 or later, 0.16.4 or later, and 0.17.0 or later. Clients using the GetReference function should upgrade to one of those versions of client-go or newer in order to work correctly against an API Server running version 1.20 or later.

You can now create clusters using the Autopilot mode. Autopilot is a new mode of operation in GKE that is designed to reduce the operational cost of managing clusters, optimize your clusters for production, and yield higher workload availability. For more information, see the Autopilot overview and blog post.

February 22, 2021

This note was updated on March 2, 2021. The issue with the Config Connector add-on with private clusters is a known issue, not a fixed issue.

GKE Node System Config is now GA.

GKE version 1.19.7-gke.1500 contains a fix for a performance issue in NodeLocal DNSCache. For more information, see NodeLocalDNS timeout errors.

Customers using the Config Connector add-on with private clusters might see an issue with all resource requests timing out. Affected customers must manually create a firewall rule that allows your cluster control plane to initiate TCP connections to your nodes on port 9443. For more information, see Adding firewall rules for specific use cases. This issue will be fixed in a future release.

February 05, 2021

Cluster Autoscaler now scales from 0 node pools, if Pods require ephemeral storage. However, scaling from 0 node pools remains unsupported for node pools that use ephemeral storage on local SSDs, as opposed to the boot disk. Node auto-provisioning scales up for Pods that explicitly require ephemeral storage. This change applies to clusters using a 1.19 version.

By default, newly created clusters are enrolled in the Regular release channel when the following flags are not specified: --cluster-version, --release-channel, --no-enable-autoupgrade, and --no-enable-autorepair.

Node auto-provisioning supports the machine-family toleration by choosing the custom machine family for creating the node pool. This change applies to clusters using a 1.19 version.

E2 is now the default machine type for node auto-provisioning. To continue using the N1 machine type, use the cloud.google.com/machine-family node selector. This change applies to clusters using a 1.19 version.

February 02, 2021

This note was updated on February 10, 2021. The node auto-upgrade from 1.15 to version 1.16.15-gke.6000 was removed from the No channel and Stable channel.

2021-04-07 update: Added a previously reported security bulletin to this releases note.

For clusters using a 1.19 version, with the Container-Optimized OS with Containerd (cos_containerd) node image, dockerd (the Docker Daemon) is not running at boot. It needs to be started manually. This issue will be fixed in a future release.

A vulnerability was recently discovered in the Linux utility sudo, described in CVE-2021-3156, that may allow an attacker with unprivileged local shell access on a system with with sudoinstalled to escalate their privileges to root on the system. GKE clusters are not affected by this vulnerability. For more information, see the GCP-2021-001 security bulletin.

Multidimensional Pod autoscaling is now available in beta in the Rapid release channel. With this feature, you can use horizontal scaling based on CPU and vertical scaling based on memory at the same time. To learn more, see Configuring multidimensional Pod autoscaling.

Support for Legacy Logging and Legacy Monitoring for GKE is extended to GKE versions 1.16 and 1.17. Cloud Operations for GKE remains the default configuration for GKE 1.16 and 1.17. Both existing and new 1.16 and 1.17 clusters can use either of the two logging options.

GKE will gradually begin using the Konnectivity service for versions 1.19.4-gke.200 and later. Konnectivity replaces SSH tunnels between the control plane and nodes with a more secure TCP proxy. The change will first be introduced for non-private clusters.

The Ubuntu image for GKE 1.16 clusters is now ubuntu-gke-1804-1-16-v20201116.

1.19 available in the Rapid channel

Kubernetes 1.19 is now available in Rapid channel. Before upgrading to 1.19.6-gke.600, read Kubernetes 1.19 Release Notes especially the Urgent upgrade notes section.

Basic authentication with a password has been removed in Kubernetes 1.19. Clusters upgraded to 1.19 can no longer use basic authentication to authenticate users to the control plane.

Seccomp (secure computing mode) support for Kubernetes has graduated to General Availability (GA). This feature can be used to increase the workload security by restricting the system calls for a Pod (applies to all containers) or individual containers.

A new seccompProfile field is added to Pod and Container securityContext objects, starting in Kubernetes 1.19.

securityContext:
  seccompProfile:
    # "Unconfined", "RuntimeDefault", or "Localhost"
    type: Localhost
    # only necessary if type == Localhost
    localhostProfile: my-profiles/profile-allow.json

The alpha seccomp annotations seccomp.security.alpha.kubernetes.io/pod and container.seccomp.security.alpha.kubernetes.io/…are deprecated in favor of the GA API field. The alpha annotations will not be honored in Kubernetes 1.22+.

If you are currently using Seccomp annotations on Pods or Containers, you should identify and transition workloads using the annotations to set the API fields before 1.21 is released on GKE (approximately in June 2021). No change on PodSecurityPolicy is required, as it supports both annotation and field seccomp profiles. You can follow the recommended steps below:

1. Locate Seccomp annotation usages. In your Kubernetes manifest files, search for "seccomp.security.alpha.kubernetes.io/pod" and "container.seccomp.security.alpha.kubernetes.io/"".

2. Add or update securityContext fields. Based on your annotation usage, add or update (if securityContext already exists) the securityContext field in Pod or Container spec. The annotations can be left in place, but must match the securityContext API field.

   Current annotation usage	Add or update securityContext
   seccomp.security.alpha.kubernetes.io/pod	In Pod's securityContext, add seccompProfile field.
   container.seccomp.security.alpha.kubernetes.io/CONTAINER_NAME	In CONTAINER_NAME's securityContext, add seccompProfile field.

3. Set values for seccompProfile. The type field of seccompProfile corresponds to the annotation value, and localhostProfile field corresponds to the path following localhost annotation value.

   Current annotation value	seccompProfile value
   unconfined	seccompProfile: type: Unconfined
   runtime/default or docker/default	seccompProfile: type: RuntimeDefault
   localhost/path/to/profile.json	seccompProfile: type: Localhost localhostProfile: path/to/profile.json

For more details, see the following pages:

• Restrict a Container's Syscalls with Seccomp
• Seccomp to GA

The widely used Ingress API has graduated to general availability in Kubernetes 1.19. The v1beta1 Ingress API is deprecated, and will no longer be served in 1.22+. Before 1.21, identify and transition clients and manifests using the v1beta1 Ingress API to use networking.k8s.io/v1.

Clusters with Google Cloud's operations suite enabled can use the following query to identify clients that access the Ingress v1beta1 APIs:

resource.type="k8s_cluster"
resource.labels.cluster_name="$CLUSTER_NAME"
protoPayload.authenticationInfo.principalEmail:("system:serviceaccount" OR "@")
protoPayload.request.apiVersion=("extensions/v1beta1" OR "networking.k8s.io/v1beta1")
protoPayload.request.kind="Ingress"
NOT ("kube-system")

Identify and transition clients and manifests using the v1beta1 Ingress APIs to use networking.k8s.io/v1 before 1.21 is released on GKE (approximately in June 2021), then verify no clients are using the v1beta1 API during the 1.21 timeframe. Workloads using the v1beta1 APIs need to be upgraded before your cluster is upgraded to GKE 1.22.

To migrate manifests to networking.k8s.io/v1:

1. Rename the spec.backend field (if specified) to spec.defaultBackend
2. Rename each backend.serviceName field to backend.service.name
3. Rename each numeric backend.servicePort field to backend.service.port.number
4. Rename each string backend.servicePort field to backend.service.port.name
5. Specify a pathType field for each defined path. Options are Prefix, Exact, and ImplementationSpecific. To match the undefined v1beta1 behavior, use ImplementationSpecific.

As an example, to migrate this v1beta1 manifest to v1:

v1beta1 manifest

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: example
spec:
  backend:
    serviceName: default-backend
    servicePort: 80
  rules:
  - http:
      paths:
      - path: /testpath
        backend:
          serviceName: test
          servicePort: 80

v1 manifest

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: example
spec:
  defaultBackend:
    service:
      name: default-backend
      port:
        number: 80
  rules:
  - http:
      paths:
      - path: /testpath
        pathType: ImplementationSpecific
        backend:
          service:
            name: test
            port:
              number: 80

The CertificateSigningRequest API has graduated to certificates.k8s.io/v1 in Kubernetes 1.19. The v1beta1 CertificateSigningRequest API is deprecated and will no longer be served in 1.22+.

Clusters with Google Cloud's operations suite enabled can use the following query to identify clients that access the CertificateSigningRequest v1beta1 APIs:

resource.type="k8s_cluster"
resource.labels.cluster_name="$CLUSTER_NAME"
protoPayload.authenticationInfo.principalEmail:("system:serviceaccount" OR "@")
protoPayload.request.apiVersion="certificates.k8s.io/v1beta1"
NOT ("kube-system")

Identify and transition clients and manifests using the v1beta1 CertificateSigningRequest API to use certificates.k8s.io/v1 before 1.21 is released on GKE (approximately in June 2021), then verifying no clients are using the v1beta1 API during the 1.21 timeframe. Workloads using the v1beta1 API need to be upgraded before your cluster is upgraded to GKE 1.22.

Differences between the v1beta1 and v1 API are as follows:

• For API clients requesting certificates:

  • spec.signerName is now required, and requests for kubernetes.io/legacy-unknown are not allowed to be created using the certificates.k8s.io/v1 API
  • spec.usages is now required, cannot contain duplicate values, and must only contain known usages

• For API clients approving or signing certificates:

  • status.conditions cannot contain duplicate types
  • status.conditions[*].status is now required
  • status.certificate must be PEM-encoded, and must contain only CERTIFICATE blocks

The Compute Engine persistent disk Container Storage Interface (CSI) Driver is now generally available in GKE. It allows you to take advantage of the latest persistent disk features without having to manually manage the CSI driver lifecycle.

For newly created clusters, the Compute Engine persistent disk CSI Driver is installed by default for the following cluster versions:

• 1.18.10-gke.2101 and later
• 1.19.3-gke.2100 and later

For all clusters, PersistentVolumeClaims created without specifying a StorageClass will continue to trigger volume provisioning using the in-tree gcePersistentDisk volume plugin. Only StorageClasses that reference the provisioner name pd.csi.storage.gke.io will provision using the CSI driver. For details, refer to Using the Compute Engine persistent disk CSI Driver.

In all GKE versions 1.14 or later, Google Cloud's operations suite for GKE adds two new options for configuring which logs and metrics are collected:

1. System and workload logging only (Monitoring disabled).
2. System monitoring only (Logging disabled).

We have discovered an issue with Internal Ingress on GKE that may require your action if you have HTTPS enabled (either through pre-shared certificates or Kubernetes Secrets). This issue does not affect External Ingress resources or MultiClusterIngress resources.

What do I need to know?

For internal Ingress on GKE versions 1.17.x and earlier, there is a known issue concerning SSL Certificate Updates on internal Ingress resources. Updating the certificate is not possible for pre-shared or Secrets-based certificates (which includes Kubernetes certificate managers). Updates to existing certificates on internal Ingress resources will not complete if attempting to update the Ingress resource.

In order to replace the certificate on an existing Ingress, the Ingress must be deleted and re-deployed. Manual updates using the gcloud compute target-https-proxies update allow a certificate to be updated on an existing Ingress without recreation, but any manual updates are overwritten by the Ingress controller if the Ingress is updated again.

What do I need to do?

If you intend to update your TLS Spec or Pre-shared Cert Spec on your Internal Ingress, you must do so by deleting your Ingress and recreating it as soon as possible, until you are able to upgrade to a patched version. Versions 1.16 are expected to be patched this month.

December 17, 2020

Internal Ingress for Internal HTTP(S) Load Balancing is now GA for 1.17.13-gke.2600+ and 1.18.10-gke.800+. Note that the certificate update issue is now patched in these GA versions. Internal Ingress for GKE 1.16 will be patched in an upcoming release.

October 19, 2020

A fix for the issue reported on September 16, 2020 where custom resources in the istio-system namespace were deleted when upgrading from GKE 1.16 to 1.17 and 1.18 is now available.

Upgrade to one of the following unaffected versions to avoid having to manually recreate these resources:

• 1.17.12-gke.1501 and higher
• 1.18.9-gke.1501 and higher

The issue only occurs during upgrades, so new clusters created in earlier versions are unaffected.

October 16, 2020

There is a known issue impacting both LTSC and SAC Windows Server images on GKE versions 1.17.x and 1.18.x. New Windows nodes take longer to join the cluster which may cause node pool creation, auto-scaling, and auto-repair operations to time out.

We recommend not upgrading clusters with Windows Server nodes pools to the following versions:

• 1.17.12-gke.1501
• 1.18.9-gke.1501

GKE versions beyond the affected versions will not have the startup time regression. Upgrade to versions greater than 1.17.12-gke.1501 and 1.18.9- gke.1501 when they become available.

For clusters not using Legacy Logging and Monitoring, upgrades from 1.14 to 1.15 are now scheduled to start in mid October. This is a change from the details announced in R29.

Node Auto-Provisioning now lets you set default values for the following features:

• Customer-managed encryption keys (CMEK)
• Secure Boot and Integrity Monitoring
• Boot disk type and size

The default value will be used by all newly created node pools.

We expect the following changes in the coming weeks. This information is not a guarantee, but is provided to help you plan for upcoming changes.

GKE will gradually upgrade clusters' control planes only to Kubernetes 1.16, beginning on or after October 6, 2020.

Node pools will not be auto-upgraded to 1.16 at this time, but can be manually upgraded completing the following instructions.

Once rolled out, 1.16 will become the most mature control plane version in the Kubernetes fleet, with newer versions available on the Rapid and Regular channels. In turn, older control plane versions will be deprecated and eventually removed from the fleet. Periodically deprecating and eventually removing beta APIs is part of a standard process to ensure that all Kubernetes fleets evolve and all APIs continue to be up-to-date.

More information is available in the GKE documentation and from the Kubernetes project.

What do I need to do?

1. Test and qualify 1.16 in a pre-production environment. We highly recommend testing upgrades in a staging or testing environment before rolling them out to production.
2. Migrate to use the current API versions before your clusters are upgraded to Kubernetes 1.16 to ensure your API clients and resource manifests can access and update API resources without interruption.

You can manually upgrade node pools to 1.16:

• The same method is available for auto-upgrade enabled clusters as GKE will not automatically upgrade node pools to 1.16 at this time.

If you are concerned about disruption, use maintenance windows and exclusions to control when the upgrade will occur.

If you have the Istio on GKE add-on enabled on a cluster, there is a known issue with the upgrade from GKE 1.16 to 1.17 versions lower than 1.17.9-gke.6300 (R30 or earlier). Any custom resources you created in the istio-system namespace are deleted during an upgrade to 1.17 (R30 or earlier). These resources must be manually recreated. We recommend that Istio on GKE users upgrade only to R31 or a later version that doesn't have the issue. The issue only occurs during upgrades, so new clusters are not affected.

September 16, 2020

If you have the Istio on GKE add-on enabled on a cluster, there is a known issue with the upgrade from GKE 1.16 to 1.17. Any custom resources you created in the istio-system namespace are deleted during an upgrade to 1.17 (R30 or earlier). These resources must be manually recreated. We recommend that Istio on GKE users do not upgrade to GKE 1.17 until a patch release fixes the issue. The fix will be rolled out in GKE release R31.

There is a known issue that prevents creating Rapid channel clusters on 1.18. To create a cluster on the Rapid channel, create a Rapid channel cluster on 1.17, and then manually upgrade to 1.18.

A vulnerability was recently discovered in the Linux kernel, described in CVE-2020-14386, that may allow container escape to obtain root privileges on the host node. All GKE nodes are affected. For more information, see the GCP-2020-012 security bulletin.

A fix is available in all versions included in this release.

September 08, 2020

Note: This release note has been updated since it was originally published. The update adds additional information about changes to Shielded Nodes.

GKE clusters in the ERROR state will be automatically deleted.

This change applies to all GKE versions.

Kubernetes 1.18 available on GKE

Kubernetes 1.18 is now available in the Rapid channel. See the Kubernetes 1.18 release notes. In particular, see the Urgent Upgrade Notes before upgrading to 1.18.

TaintBasedEvictions are generally available in GKE in 1.18 clusters.

Consumers of the certificatesigningrequests/approval API must now have permission to approve certificate signing requests (CSRs) for the specific signer requested by the CSR. More information on the new signerName field and the required authorization can be found in the CSR documentation.

GKE now allows clusters of up to 15,000 nodes when using GKE 1.18. To scale a cluster beyond 5,000 nodes, you must contact support to raise your quota.

In GKE 1.18, Shielded Nodes are enabled by default for newly created clusters. Clusters upgrading to 1.18 are unaffected by this change.

Shielded Nodes are only compatible with Container-Optimized OS and Ubuntu images. If you are using a custom image or Windows images you should disable Shielded Nodes.

While the Kubernetes API does support the use of the ingressClassName and ingressClass resources, the Compute Engine ingress controller does not.

Cluster Autoscaler for GKE 1.18 could have problems with very large clusters or scale ups where there are over 5,000 nodes in the cluster or over 1,000 nodes being added at the same time. A fix is coming soon.

Change default machine type to E2

GKE is changing the default machine type for new clusters and node pools from n1-standard-1 to e2-medium. This change impacts new node pools created using versions 1.17.6 and higher. If you do not specify a machine type during your cluster or node pool creation workflow from node pool version 1.17.6 onwards, the newly provisioned clusters and node pools will default to e2-medium VMs. Note that this change does not impact your existing node pools that are auto-upgraded or manually upgraded to version 1.17.6 or higher.

E2 machine types do not support GPUs, local SSDs or sole tenancy. As such, you will receive an error message advising you to specify a compatible machine type for your workloads if you:

• Use node pool version 1.17.6+ to provision new worker nodes using the default machine type with either GPUs, local SSDs or Sole tenancy enabled (for example, gcloud container clusters create mycluster --accelerator type=nvidia-tesla-v100, count=2), or
• Use scripts that provision GPUs or local SSDs and do not specify a specific machine type. Furthermore, these scripts will not work until you specify your desired compatible machine type.

What do I need to do?

Use the following interface(s) of your choice to explicitly configure your machine type setting for newly provisioned machines to be anything other than the new e2-medium default:

• gcloud
  • Specify --machine-type
• API
  • Specify machineType in NodeConfig
• Cloud Console
  • Specify machine type in for node pools

• Terraform

  • Specify machine_type in node_config

  • Specify machine_type for node_pools in the module "gke" section of your Terraform configuration code.

    We strongly recommend explicitly setting the machine type to n1-standard-1 or any other suitable VM type if one or more of these situations apply to you: You are concerned about your single threaded application's performance on the new shared-core e2-medium default machine type. You use GPUs or local SSDs or sole tenancy, all of which are unsupported by the new default machine type e2-medium.

Starting September 1, 2020, we will automatically delete Google Kubernetes Engine (GKE) clusters that have ERROR status.

What do I need to know?

GKE clusters might end up with ERROR status (red exclamation mark in the cluster status page) in rare cases when cluster creation or deletion operation encounters an unexpected error. Previously, such clusters remained in your accounts and could have been partially usable. ERROR status clusters are excluded from the GKE cluster management fee.

Starting September 1, 2020, we will begin blocking access to such ERROR status clusters and deleting them automatically.

What do I need to do?

If you are relying on any of the clusters with ERROR status in your projects, stop using them by September 1, 2020.

July 17, 2020

Up to 50 TCP/UDP ports are supported per internal TCP/UDP load balancer IP when deploying through GKE Services with shared IP addresses. This also permits multi-protocol TCP and UDP support for the same Service IP. Shared IP is now available in Beta for all existing GKE versions.

SSL Policies which allow policy-enforced TLS and cipher settings are available in Beta for external Ingress and multi-cluster Ingress. Custom health checks, which allow users to declaratively customize parameters of the load balancer health check, are also now available for external, internal, and multi-cluster Ingress. For feature support status and version compatibility see Ingress Features.

The BackendConfig CRD is now GA in GKE 1.16-gke.3+ clusters which promotes most BackendConfig features (IAP, timeouts, affinity, user-defined request headers, and so on) to GA across internal, external, and multi-cluster Ingress. See Ingress Features for detail on explicit version support.

Container-native Ingress using Network Endpoint Groups (NEGs) is now default (with some exceptions) for new Services deployed in GKE 1.17.6-gke.7+ clusters. The cloud.google.com/neg: '{"ingress": true}' annotation will be automatically applied to any Services deployed in these clusters without any explicit action from users to enable container-native Ingress.

Customer Managed Encryption Keys (CMEK) are now generally available for GKE. CMEK for GKE lets you secure your node boot disks as well as attached persistent storage by encrypting the data encryption keys that encrypt your data. To learn more, see Using customer-managed encryption keys.

The Kubernetes Engine Monitoring feature has been renamed in the Google Cloud Console and documentation to Cloud Operations for GKE. No functional changes were made with this change. Enabling Cloud Operations for GKE continues to collect logs and metrics for your cluster and workloads as it did before.

If you have node pools with kubernetes.io or k8s.io labels and want to upgrade to 1.16, you must remove the labels before upgrading.

For more information on this change, see the Kubernetes Node Restriction enhancement.

There is a known that may cause multiple Pods on the same node to be allocated with the same IPv4 address leading to possible service disruption. We will automatically upgrade your cluster master to the next available patch version which will include a fix to the issue.

What do I need to know?

• Ensure your cluster(s) are subscribed to a release channel, or you have node auto-upgrade enabled. If so, your cluster(s) will be automatically upgraded as described below.
• If you are experiencing any issues or do not want to use auto-upgrade you can manually initiate an upgrade at your earliest convenience.

What do I need to do?

If you are experiencing issues and wish to update proactively:

• Follow the steps in the Manually upgrading a cluster page to upgrade the cluster master.
• Upgrade your node pool by applying the latest patch available for your node version.

June 02, 2020

Note: This release note has been updated since it was originally published. The update adds affected versions of 1.14 and 1.15.

As part of ensuring better representation of available resources on the node for e2 burstable node types, GKE has decided to reduce the allocatable CPU resources available to schedule user workloads (known as the node allocatable resources) on e2-micro, e2-small, and e2-medium machine types.

What do I need to know?

Today, e2-micro, e2-small, and e2-medium have 1930 mCPU of allocatable resources for Kubernetes to schedule Pods on per node, and following this change it will be 940m CPU. Kubernetes uses the node allocatable resources during scheduling to decide how many Pods it should place on the node. If your workloads are currently requesting more CPU resources than what will be available after upgrading, they may become unscheduled after upgrade.

We are making this change in order to more accurately represent the resources available in these machine types. These machine types can temporarily burst to 2 vCPUs, but this is not sustained. The underlying compute capabilities and resources are not changing, the machines retain the ability to temporarily burst to 2 vCPU, this change only affects how many resources the Kubernetes scheduler considers when allocating Pods to nodes.

When your cluster is upgraded to 1.14.10-gke.42, 1.15.11-gke.18, 1.16.8- gke.17, or 1.17.5-gke.5 (whether you perform this manually or you are automatically upgraded), your workloads may become unscheduled if there are not enough allocatable resources in the cluster.

What do I need to do?

Prior to upgrading your nodes to version 1.16.8-gke.17 and 1.17.5-gke.5 or later

Take a moment to review your Pod resource requests. To see the allocated resources on your node, you can open Kubernetes Engine in the Google Cloud Console and select your cluster. On the Nodes tab for your cluster, the column CPU requested shows the total CPU requests on the node.

Alternatively, from the command line:

1. Run kubectl get nodes to get a list of node names.
2. Run kubectl describe node node-name and look at the Allocated resources section. Under the column Requests, find the row for cpu.

If you have nodes of type e2-micro, e2-small, and e2-medium where more than 940mCPU is requested, Pods will be rescheduled onto other nodes after upgrade. You must have enough allocatable capacity on other nodes.

To ensure you have enough allocatable capacity, you can:

• Enable auto-scaling on your node pool. Auto-scaling will automatically provision the right number of nodes automatically, provided the Pod requests do not exceed that of the entire node
• Increase the number of nodes in the cluster, or add larger node types if you have Pods that make CPU requests which exceed the capacity of existing nodes
• Decrease the resource requests made by your workloads on these nodes so that they will still fit after the upgrade, by modifying the CPU resource requests of the PodSpec. Pods will be able to burst to the original CPU capacity for short periods as long as resource limits are not changed.

After you have upgraded your nodes to versions 1.14.10-gke.42, 1.15.11-gke.18, 1.16.8-gke.17, or 1.17.5-gke.5 or later:

Review the status of your Pods by running kubectl get pods.

If any are indicated as Pending, it may indicate that there were not enough resources available to schedule them. Follow the steps above to either add more nodes, or reduce the CPU resource requests in the PodSpec.

Version updates

GKE cluster versions have been updated.

Note: Your clusters might not have these versions available. Rollouts begin on the day of the note and take four or more business days to be completed across all Google Cloud zones.

New versions available for upgrades and new clusters

The following Kubernetes versions are now available for new clusters and for opt-in control plane upgrades and node upgrades for existing clusters. For more information on the Kubernetes versioning scheme, see Versioning.

No channel

• 1.14.10-gke.36 is now available.
• 1.15.11-gke.9 is now available. This version updates Calico to 3.8.7. This version fixes an issue where Calico Pods would fail to initialize after restarting. The issue occurred because the Calico CNI script tried to overwrite a file which was referenced by Kubelet at the same time. For more information on the fix, see the open source documentation.
• 1.17.4-gke.6 is now available in alpha clusters.

Stable channel

April 10, 2020

Note: This release note has been updated since it was originally published. The Coming soon section below was added.

Ingress access logging is now a configurable feature called logging in versions 1.16.8-gke.10 and later. This allows Ingress access logging to be toggled on or off through the BackendConfig resource.

HTTP access logging for newly created Ingress resources is being deprecated across various GKE versions on May 12th, 2020. Any new Ingress resources created with the following versions after May 12th will have access logging disabled for that Ingress resource and will not record Ingress HTTP requests in Cloud Logging. Note that existing Ingress resources will continue to log HTTP requests unless the Ingress resource is redeployed. The following GKE versions are affected:

• 1.12
• 1.13
• 1.14 clusters less than 1.14.10-gke.30
• 1.15 clusters less than 1.15.9-gke.22
• 1.16 clusters less than 1.16.6-gke.12

Clusters whose masters are on 1.14.10-gke.30, 1.15.9-gke.22, 1.16.6-gke.12 or later versions are not impacted and HTTP access logging remains defaulted to "on" for all new and existing Ingress resources. If you're currently using access logging for GKE Ingress, we highly recommend upgrading to these versions or higher before May 12th to avoid loss of HTTP access logs for new Ingress resources.

In GKE 1.18, access logging will be changed to default to "off" for the GKE Ingress. Enabling access logging through the logging parameter is required to enable it for Ingress resources.

Google Kubernetes Engine will gradually upgrade clusters in the regular channel to GKE 1.16 beginning on or after April 13, 2020.

April 07, 2020

Version updates

GKE cluster versions have been updated.

Note: Your clusters might not have these versions available. Rollouts begin on the day of the note and take four or more business days to be completed across all Google Cloud zones.

New versions available for upgrades and new clusters

The following Kubernetes versions are now available for new clusters and for opt-in control plane upgrades and node upgrades for existing clusters. For more information on the Kubernetes versioning scheme, see Versioning.

No channel

• 1.15.11-gke.5 is now available.

Stable channel

There are no new releases in the Stable release channel.

Regular channel

There are no new releases in the Regular release channel.

Rapid channel

• 1.16.8-gke.8 is now available in the Rapid release channel. The node image for Container-Optimized OS is updated to cos-77-12371-208-0.

Due to the recent Windows Server security update provided by Microsoft in February 2020, a container incompatibility issue was introduced. To avoid disruption to your workloads, we have turned off Google Kubernetes Engine (GKE) auto-upgrade for the impacted clusters.

What do I need to know?

As a consequence of Microsoft's security update, your workloads may end up in a failed state due to broken compatibility if the host Windows Server image has the security update and the container base image does not have the update.

We have turned off auto-upgrade on the impacted GKE clusters to prevent this compatibility issue from affecting your workloads.

The security update will be available in the rapid channel in GKE starting April 6, 2020. Beginning April 20, 2020, Windows Server container support in GKE, along with the security update will be available on the regular channel.

What do I need to do?

We strongly recommend you to rebuild your container images with the base Windows images that include Windows Updates from March 2020, then manually upgrade your node pool to the latest GKE version. Please follow the following steps:

1. Disable auto-upgrade on the Windows node pool(s).
2. When the first step is complete, Google will restart the cluster auto-upgrade. Please note that this could take a few days. The cluster's master and the Linux node pool(s) will be upgraded. The Windows node pool will not get upgraded as auto-upgrade is disabled in step number one.
3. After the cluster master upgrade is complete and you have rebuilt your container images, manually upgrade your Windows node pool.
4. After completing step number three, you can turn back on the auto-upgrade option. If you choose to turn the auto-upgrade option back on, please use multi-arch (or multi-platform) images to take advantage of the auto-upgrade feature.

Incompatibility issues such as this one are a rare occurrence as it is against Microsoft's typical guidance for the security updates. Rest assured that if such issues occur again, we will keep you posted. Please stay up to date with GKE's release notes for the latest info.

If you have any questions or require assistance, please email us or contact Google Cloud Support.

The ability to create clusters with node pools running Microsoft Windows Server is now in Beta. This feature is currently only available in the Rapid release channel.

January 24, 2020

This issue was resolved January 27, 2020.

Do not create a cluster with versions 1.15.7-gke.23, 1.14.10-gke.17, or 1.14.9-gke.23 if you depend on Workload Identity. Workload Identity is not working for newly created clusters in these versions due to a recently-discovered issue. Clusters upgraded to one of these versions are not affected. A fix will be released in the next GKE release. As workaround, you can create a cluster at a lower version, then upgrade.

The region asia-northeast3 in Seoul is now available.

Node image changes

The COS kernel previously reported on November 22nd, 2019, was discovered to cause kernel panics in certain workloads. The 1.13 and 1.14 versions available in this release were rolled back to a known stable version of COS. GKE 1.13 and 1.14 will continue to use cos-u-73-11647-293-0 while our team works to develop a permanent fix.

Application Delivery is now in Beta. This feature manages configurations for your GKE workloads declaratively with Git. For more information, see Application Delivery.

NodeLocal DNSCache is now in Beta for GKE clusters 1.15 and above. NodeLocal DNS is an optional feature for local DNS resolution to every GKE node for enhanced DNS scale and capacity.

Object Browser is now available to inspect resources on GKE clusters in Google Cloud Console. For more information, go to Dashboards.

All private clusters you create now reuse VPC Network Peering connections.

You can now use Customer-managed encryption keys (beta) to control the encryption used for node boot disks as well as attached persistent disks in your clusters.

Consuming reservations in GKE is now generally available. Reservations allow you to reserve resources in a specific zone to ensure sufficient capacity is available for your workloads.

New clusters and node-pools created with the GKE API will have node auto-upgrade enabled by default. This change ensures that your clusters have the most recent default Kubernetes version, bug fixes, and security patches. Existing scripts running against the gcloud CLI or integrating with the GKE API will follow this new default behavior.

Node autoupgrades keep the nodes in your cluster up to date with the cluster master version when your master is updated on your behalf. To disable it explicitly, set autoUpgrade to false in the NodeManagement object.
