CVE-2022-4450, CVE-2022-2097, CVE-2023-0286, CVE-2023-0215, and CVE-2022-4304 have been patched in all minor versions for all existing and new clusters using the Compute Engine persistent disk CSI driver.

For VPC peering-based private clusters running version 1.27 or later, traffic from kube-apiserver to nodes routes through the Konnectivity service. If your cluster was created before 2020-09-17, this traffic from does not route through Konnectivity unless you have rotated the control plane IP address after 2020-09-17.

May 23, 2023

CVE-2023-26604 has been fixed in clusters running version 1.25 using the Filestore CSI driver. The fix is transparent, but to mitigate instability, it is available by manually upgrading the cluster to the newest 1.25 patch version. The CVE is not present in clusters running version 1.26 or later.

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.

If containerd restarts on a node that has existing running Pods that use Workload Identity, those specific Pods might fail to access Google Cloud APIs and might return POD_FINDER_IP_MISMATCH errors. This affects nodes with the following GKE versions:

• 1.22.16-gke.2100 and later
• 1.23.14-gke.1900 and later
• 1.24.7-gke.700 and later
• 1.25.0 and later
• 1.26.0 and later

This issue will be fixed in a future release

Starting from GKE control plane versions 1.26.0-gke.2200, 1.25.5-gke.2200, 1.24.9-gke.2200 or later, SingleStack IPv6 and DualStack (IPv4/IPv6) services, stub domains, and upstream nameservers are supported with Cloud DNS for GKE.

A known issue with kube-dns receiving a DNS response from an upstream DNS resolver with a large TTL has been fixed. For more information, see Large TTL from DNS upstream servers

Public zonal clusters upgraded to GKE versions 1.24 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.

• Control planes and nodes with auto-upgrade enabled in the Rapid channel will be upgraded from version 1.23 to version 1.23.13-gke.900 with this release.
• Control planes and nodes with auto-upgrade enabled in the Rapid channel will be upgraded from version 1.25 to version 1.25.4-gke.1600 with this release.

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.

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.

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.
