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/

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.

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.

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.

1.24 is now available in the Rapid channel

Kubernetes 1.24 is now available in the Rapid channel. Before upgrading, read the Kubernetes 1.24 Release Notes, especially the action required and deprecation sections.

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

1.23 is now available in the Rapid channel

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

Notable features

Beta: PodSecurity admission

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

Notable changes and bug fixes

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

Before upgrading to 1.23, ensure any non-local aggregated API servers, admission webhooks, and custom resource conversion webhooks in your cluster are served using valid TLS certificates.
At cluster version 1.22.3-gke.700 or higher, GKE provides a Cloud Audit log to check if your cluster contains an affected service. You can use the following filter to search for the logs:
```
logName: "projects/$PROJECT/logs/cloudaudit.googleapis.com%2Factivity"
resource.type = "k8s_cluster"
operation.producer = "k8s.io"
"invalid-cert.webhook.gke.io"
```
If you are not affected you won't see any logs. If you do see such an audit log, it will include the name of the service (whether webhook or aggregated API).

New API versions

flowcontrol.apiserver.k8s.io/v1beta2 FlowSchema, PriorityLevelConfiguration

New API versions in 1.22

The pods/eviction subresource now accepts policy/v1 eviction requests in addition to policy/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 field ownership, running on the Kubernetes API server. Server-side Apply helps users and controllers create and modify their resources via declarative configurations by sending their fully specified intent. Refer to server-side apply documentation 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 a maxSurge rollout parameter, which allows running updated pods for the DaemonSet on nodes before removing old pods. Refer to the DaemonSet API documentation for more information.

Beta: Suspended jobs

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

Beta: podAffinity namespace selection

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

Notable changes and bug fixes in 1.22

The terminationGracePeriodSeconds field on pod specs and container probes should not be negative. Negative values of terminationGracePeriodSeconds will be treated as the value 1 on the delete path. Immutable field validation will be relaxed in order to update negative values. In a future release, negative values will not be permitted. (#98866)
As a mitigation for CVE-2021-25740, newly created Kubernetes 1.22 clusters no longer include write access to the Endpoints API in the edit and admin roles by default. Existing clusters upgraded to Kubernetes 1.22 retain previous permissions in those roles. For instructions to re-add Endpoints write access to the edit and admin roles in newly created 1.22 clusters, refer to the RBAC documentation.

1.21 available in the Rapid channel

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

1.21 Features

The following features are introduced in version 1.21:

CronJob (GA)

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

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

PodDisruptionBudget (GA)

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

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

EndpointSlice (GA)

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

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

Default namespace label (Beta)

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

Bound service account token volumes (Beta)

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

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

1.21 New Beta and Stable APIs

The following Stable APIs are new in 1.21:

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

The following Beta APIs are new in 1.21:

storage.k8s.io/v1beta1 CSIStorageCapacity

1.21 Deprecated APIs

The following APIs are deprecated in the 1.21 release:

PodSecurityPolicy
- policy/v1beta1 PodSecurityPolicy

1.20 available in the Rapid channel

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

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

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

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

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

A namespaced object with an ownerReference to another namespaced object which does not exist in the same namespace is now consistently treated as having a missing owner and is deleted.
A cluster-scoped object with an ownerReference to a namespaced object is now consistently treated as having an unresolvable owner, and is ignored by the garbage collector.
Starting in version 1.20, when a namespace mismatch between a child and owner object is detected, an event with a reason code of OwnerRefInvalidNamespace is recorded.

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

1.19 available in the Rapid channel

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

v1beta1 manifest

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

v1 manifest

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

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

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

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

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

Differences between the v1beta1 and v1 API are as follows:

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