Deprecated in-tree volume support

• The Ceph CephFS (kubernetes.io/cephfs) and RBD (kubernetes.io/rbd) volume plugins aredeprecated 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 athttps://github.com/ceph/ceph-csi/), or a Google Cloud-managed solution likeFilestore.

• For more information, refer to theOSS Kubernetes announcement andhttps://github.com/ceph/ceph-csi/

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, useflowcontrol.apiserver.k8s.io/v1, which is available since Kubernetes 1.29
• Thestatus.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, seeKEP-4004.

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.

1.30 is now available in the Rapid channel

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

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 theCeph CSI driver project), or a Google Cloud-managed solution likeFilestore. For more information, refer to the OSS Kubernetes announcement and to theCeph CSI driver project.

New APIs in 1.30

The following APIs are new in Kubernetes 1.30:

• admissionregistration.k8s.io/v1ValidatingAdmissionPolicyBinding andValidatingAdmissionPolicy

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 theKubernetes 1.29 Release Notes.

Removed APIs

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

• flowcontrol.apiserver.k8s.io/v1beta2 FlowSchema,PriorityLevelConfiguration
  • Deprecated since 1.26
  • Instead, useflowcontrol.apiserver.k8s.io/v1beta3 available since 1.26, orflowcontrol.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 ofwebhook servers andextension 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 toEnsure compatibility of TLS certificates before upgrading to GKE 1.29.

Deprecated APIs

• The following Beta versions of graduated APIs aredeprecated in 1.29 in favor of newer versions:
  • flowcontrol.apiserver.k8s.io/v1beta3 FlowSchema,PriorityLevelConfiguration
    • Deprecated since 1.29
    • Instead, useflowcontrol.apiserver.k8s.io/v1, available since 1.29
• Thestatus.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, seeKEP-4004.

New Features

• The betaValidatingAdmissionPolicy feature can be opted into byenabling the beta APIs.
• initContainers can now be configured assidecar 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.

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 theCeph CSI GitHub repo, or use a Google-managed solution such asFilestore.
• For more information, refer to theOSS Kubernetes announcement and theCeph CSI GitHub repo.

New APIs

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

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, seemigrating 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 andavoiding 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 theTokenRequest API to obtain time-bound tokens that are not readable by other API clients. Thekubectl 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 bycreating 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 thesecrets[*].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 typekubernetes.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 1.24deprecates 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 withremoval 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, seePodSecurityPolicy deprecation.

• The following Beta versions of graduated APIs will beremoved 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 beremoved 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 beremoved 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.

Notable features

Beta: PodSecurity admission

PodSecurity replaces the deprecatedPodSecurityPolicy admission controller(which will be removed in 1.25).PodSecurity is an admission controller thatenforcesPod Security Standardson Pods in a Namespace based on specific namespace labels that set theenforcement level. In 1.23, the PodSecurity feature is enabled by default, andapplies to namespaces that opt into enforcement. Refer to thePodSecurity documentationandPodSecurityPolicy migration guidefor more information.

1.23 is now available in the Rapid channel

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

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 TLScertificates 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 clusterare served using valid TLS certificates.

• At cluster version 1.22.3-gke.700 or higher, GKE provides a Cloud Audit log tocheck if your cluster contains an affected service. You can use the followingfilter 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 auditlog, it will include the name of the service (whether webhook or aggregatedAPI).

Notable changes and bug fixes in 1.22

• TheterminationGracePeriodSeconds field on pod specs and container probesshould not be negative. Negative values ofterminationGracePeriodSecondswill be treated as the value1 on the delete path. Immutable fieldvalidation will be relaxed in order to update negative values. In a futurerelease, negative values will not be permitted. (#98866)

• As a mitigation forCVE-2021-25740,newly created Kubernetes 1.22 clusters no longer include write access to theEndpoints API in theedit andadmin roles by default. Existing clustersupgraded to Kubernetes 1.22 retain previous permissions in those roles. Forinstructions to re-add Endpoints write access to theedit andadminroles in newly created 1.22 clusters, refer to theRBAC documentation.

Deprecated API versions

These APIs are still served in version 1.22 but are in a deprecation period, andwill be removed in 1.25:

• PodSecurityPolicy
  • policy/v1beta1 PodSecurityPolicy
  • Deprecated in 1.21 withremoval targeted for version 1.25.
• The following Beta versions of graduated APIs will beremoved in 1.25 in favor of their GA versions:

  • policy/v1beta1 PodDisruptionBudget, deprecated since 1.21
  • batch/v1beta1 CronJob, deprecated since 1.21

New API versions in 1.22

Thepods/eviction subresource now acceptspolicy/v1 eviction requests inaddition topolicy/v1beta1 eviction requests(#100724)

Notable features in 1.22

GA: Server-side Apply

Server-side Apply is a new object merge algorithm, as well as tracking of fieldownership, running on the Kubernetes API server. Server-side Apply helps usersand controllers create and modify their resources via declarative configurationsby sending their fully specified intent. Refer toserver-side applydocumentation for more information. Improvements in 1.22 include:

• scale subresource ownership is tracked correctly (#98377)
• label selector fields are applied atomically (#97989)

Beta: DaemonSet maxSurge

DaemonSet objects now support amaxSurge rollout parameter, which allowsrunning updated pods for the DaemonSet on nodes before removing old pods. Referto theDaemonSet API documentation for more information.

Beta: Suspended jobs

Job objects can now be created or placed in a suspended state, to allowhigher-level control over ordering and scheduling of batch workloads. Refer totheJob documentation for more information.

Beta: podAffinity namespace selection

Pod affinity rules can now specify namespaced using a label selector, inaddition to a fixed list of namespace names. Refer to thepod affinity documentation for more information.

Removed API versions in 1.22

The following Beta versions of previously graduated APIs are removed in 1.22 infavor of the GA versions. All existing objects can be interacted with via thestable APIs. Update API clients and manifests to use the GA APIs beforeupgrading. For more information, see theKubernetes 1.22 deprecated APIsguide.

1.21 available in the Rapid channel

Kubernetes version 1.21 is now available in the Rapid channel. Before upgrading,read theKubernetes 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 performanceimprovements and allowing scheduled jobs to be run using a stable API.

• This resource is now available in thebatch/v1 group/version.
• Thebatch/v1beta1 group/version is deprecated, and will be removed inversion 1.25. See themigration guide for details.

PodDisruptionBudget (GA)

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

• This resource is now available in thepolicy/v1 group/version.
• Thepolicy/v1beta1 group/version is deprecated, and will be removed inversion 1.25. See themigration guide for details.

EndpointSlice (GA)

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

• This more scalable API for service discovery is now enabled on all clustersand is promoted todiscovery.k8s.io/v1.
• Thediscovery.k8s.io/v1beta1 group/version is deprecated, and will beremoved in version 1.25. See themigration guide for details.

Default namespace label (Beta)

Namespace API objects now have akubernetes.io/metadata.name label matchingtheirmetadata.name field to allow selecting any namespace by its name using alabel selector. This can be used for objects which select namespaces by label,such asadmission webhooks andnetwork policies.

Bound service account token volumes (Beta)

• The API credentials injected into containers at/var/run/secrets/kubernetes.io/serviceaccount/tokenare now time-limited, auto-refreshed, and invalidated when the containingpod is deleted.
• By default, injected tokens are given an extended lifetime so they remainvalid even after a new refreshed token is provided. The metricserviceaccount_stale_tokens_total and the audit annotationauthentication.k8s.io/stale-token can be used to monitor for workloadsthat depend on the extended lifetime and are continuing to use tokens evenafter a refreshed token is provided to the container.
• Clients should reload the token from disk periodically (once per minute isrecommended) to ensure they use the refreshed token.k8s.io/client-goversion 11.0.0+ and 0.15.0+ reload tokens automatically.

1.21 New Beta and Stable APIs

The following Stable APIs are new in 1.21:

• batch/v1 CronJob
