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
• 1.30.4-gke.1129000

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 spamming logs.

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.

You can now preload data or container images in new nodes on GKE, enabling faster workload deployment and autoscaling. 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.

Kubernetes 1.30 is now available in the Rapid channel. For more information about the content of Kubernetes 1.30, read the Kubernetes 1.30 Release Notes.

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.

A known issue causes a subset of Pods in GKE Autopilot clusters to occasionally become stuck during termination or creation. As a result, we temporarily disabled bursting in Autopilot clusters that were created or upgraded to version 1.29.2-gke.1060000 and later on or after April 24, 2024. Clusters that enabled bursting prior to April 24, 2024 continue to support bursting. For information and troubleshooting steps, see Pods stuck during termination or creation.

Cilium cluster-wide network policies are now generally available with the following GKE versions:

• 1.28.6-gke.1095000 or later
• 1.29.1-gke.1016000 or later

You can now control your GKE workloads' ingress and egress traffic cluster-wide, without being bound to a namespace for your network policies. This new capability is intended to streamline network policies for GKE platform administrators looking for a uniform way to apply policies across namespaces or application teams.

Cilium cluster-wide network policy is available in all GKE editions.

To learn more, read Control cluster-wide communication using network policies.

Workloads running on GKE clusters with COS-based nodes may experience DNS resolution issues. The likelihood of impact is low and not all clusters are impacted. The issue is resolved on the following minimal GKE node versions:

• For 1.27: 1.27.11-gke.1118000
• For 1.28: 1.28.7-gke.1100000
• For 1.29: 1.29.2-gke.1217000

Clusters with a node version that is lower than 1.27.3-gke.1200 are not affected.

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

• CVE-2024-1085

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.

January 19, 2024

Note: This is a correction of the Aug 29, 2023 release note, which incorrectly stated the qualifying patch versions for TPUs. See the availability chart for version qualification information.

You can 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. To learn more, see About TPUs in GKE. See TPU availability in GKE to find the TPU availability depending on the machine type and version.

January 18, 2024

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

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

The Observability tab in the cluster details page for each cluster and in the GKE cluster list page now shows GPU metrics if the cluster has GPU nodes. For more information, see View observability metrics.

December 14, 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.

October 30, 2023

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.

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.

August 22, 2023

The europe-west10 region in Berlin, Germany is now available.

August 17, 2023

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.

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.

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.

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.

In GKE version 1.26, for VPC peering-based private clusters that were created after 2020-08, the Konnectivity service will be initialized but not used. Traffic from kube-apiserver to nodes continues to route directly.

May 02, 2023

The managed Cloud Storage FUSE CSI driver for GKE is now available in Preview in GKE versions 1.26.3 and later. You can use this driver to consume Cloud Storage buckets for GKE workloads.

We're working on automatically enabling the PD CSI Driver on upgrades to 1.25, for clusters with the add-on disabled. There are no cost implications for enabling the driver, and it requests only a small amount of node resources. This upgrade enables gce-pd volumes to continue working on Kubernetes clusters version 1.25 and greater. You can still disable the driver manually after upgrade. For more details, please read here.

Two new vulnerabilities, CVE-2023-0240 and CVE-2023-23586, have been discovered in the Linux kernel that could allow an unprivileged user to escalate privileges. For more information, see the GCP-2023-003 security bulletin.

In GKE 1.27 and later, GKE nodes will not keep compressed image layers in containerd's content store once they have been unpacked, by setting discard_unpacked_layers=true in containerd configuration. This change will not impact workloads running as Kubernetes Pods and Containers. However, if your workload relies on the image layers in containerd's content store, please make sure your workload can handle the case where image layers are missing.

The new release of the GKE Gateway controller (2023-R01) is now generally available. With this release, the GKE Gateway controller will provide the following new capabilities:

• Gateway API on Autopilot clusters by default (GKE 1.26+)
• The Global External HTTP(S) Load Balancer GatewayClass graduates to GA
• Global Access for the gke-l7-rilb GatewayClass
• SSL Policies
• HTTP-to-HTTPS redirect
• Cloud Armor integration

You can check all the supported capabilities per GatewayClass in this page.

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.

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.

CVE-2022-24675 CVE-2022-2068 CVE-2022-28327 have been patched in the PD CSI driver in 1.23 for newly created clusters.

For VPC-native clusters, the user-managed secondary range for Services can now be shared among clusters in the same subnet. The Services range no longer needs to be unique for clusters on the same subnet. Shared Services ranges are backwards-compatible with all GKE versions.

It also provides visibility into ingestion into Google Cloud Managed Service for Prometheus and Cloud Logging. For more information, see View observability metrics.

August 08, 2022

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.

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.
