Feature Gates

This page contains an overview of the various feature gates an administrator can specify on different Kubernetes components.

See feature stages for an explanation of the stages for a feature.

Overview

Feature gates are a set of key=value pairs that describe Kubernetes features. You can turn these features on or off using the --feature-gates command line flag on each Kubernetes component.

Each Kubernetes component lets you enable or disable a set of feature gates that are relevant to that component. Use -h flag to see a full set of feature gates for all components. To set feature gates for a component, such as kubelet, use the --feature-gates flag assigned to a list of feature pairs:

--feature-gates=...,GracefulNodeShutdown=true

The following tables are a summary of the feature gates that you can set on different Kubernetes components.

The "Since" column contains the Kubernetes release when a feature is introduced or its release stage is changed.
The "Until" column, if not empty, contains the last Kubernetes release in which you can still use a feature gate.
If a feature is in the Alpha or Beta state, you can find the feature listed in the Alpha/Beta feature gate table.
If a feature is stable you can find all stages for that feature listed in the Graduated/Deprecated feature gate table.
The Graduated/Deprecated feature gate table also lists deprecated and withdrawn features.

Note:

For a reference to old feature gates that are removed, please refer to feature gates removed.

Using a feature

Feature stages

A feature can be in Alpha, Beta or GA stage. An Alpha feature means:

Disabled by default.
Might be buggy. Enabling the feature may expose bugs.
Support for feature may be dropped at any time without notice.
The API may change in incompatible ways in a later software release without notice.
Recommended for use only in short-lived testing clusters, due to increased risk of bugs and lack of long-term support.

A Beta feature means:

Usually enabled by default. Beta API groups are disabled by default.
The feature is well tested. Enabling the feature is considered safe.
Support for the overall feature will not be dropped, though details may change.
The schema and/or semantics of objects may change in incompatible ways in a subsequent beta or stable release. When this happens, we will provide instructions for migrating to the next version. This may require deleting, editing, and re-creating API objects. The editing process may require some thought. This may require downtime for applications that rely on the feature.
Recommended for only non-business-critical uses because of potential for incompatible changes in subsequent releases. If you have multiple clusters that can be upgraded independently, you may be able to relax this restriction.

Note:

Please do try Beta features and give feedback on them! After they exit beta, it may not be practical for us to make more changes.

A General Availability (GA) feature is also referred to as a stable feature. It means:

The feature is always enabled; you cannot disable it.
The corresponding feature gate is no longer needed.
Stable versions of features will appear in released software for many subsequent versions.

List of feature gates

Each feature gate is designed for enabling/disabling a specific feature.

AdmissionWebhookMatchConditions: Enable match conditions on mutating & validating admission webhooks.
AggregatedDiscoveryEndpoint: Enable a single HTTP endpoint /discovery/<version> which supports native HTTP caching with ETags containing all APIResources known to the API server.
AllowDNSOnlyNodeCSR: Allow kubelet to request a certificate without any Node IP available, only with DNS names.
AllowInsecureKubeletCertificateSigningRequests: Disable node admission validation of CertificateSigningRequests for kubelet signers. Unless you disable this feature gate, Kubernetes enforces that new kubelet certificates have a commonName matching system:node:$nodeName.
AllowServiceLBStatusOnNonLB: Enables .status.ingress.loadBalancer to be set on Services of types other than LoadBalancer.
AllowUnsafeMalformedObjectDeletion: Enables the cluster operator to identify corrupt resource(s) using the list operation, and introduces an option ignoreStoreReadErrorWithClusterBreakingPotential that the operator can set to perform unsafe and force delete operation of such corrupt resource(s) using the Kubernetes API.
AnonymousAuthConfigurableEndpoints: Enable configurable endpoints for anonymous auth for the API server.
AnyVolumeDataSource: Enable use of any custom resource as the DataSource of a PVC.
APIListChunking: Enable the API clients to retrieve (LIST or GET) resources from API server in chunks.
APIResponseCompression: Compress the API responses for LIST or GET requests.
APIServerIdentity: Assign each API server an ID in a cluster, using a Lease.
APIServerTracing: Add support for distributed tracing in the API server. See Traces for Kubernetes System Components for more details.
AppArmor: Enable use of AppArmor mandatory access control for Pods running on Linux nodes. See AppArmor Tutorial for more details.
AppArmorFields:
Enable AppArmor related security context settings.

For more information about AppArmor and Kubernetes, read the AppArmor section within security features in the Linux kernel.
AuthorizeNodeWithSelectors: Make the Node authorizer use fine-grained selector authorization. Requires AuthorizeWithSelectors to be enabled.
AuthorizeWithSelectors: Allows authorization to use field and label selectors. Enables fieldSelector and labelSelector fields in the SubjectAccessReview API, passes field and label selector information to authorization webhooks, enables fieldSelector and labelSelector functions in the authorizer CEL library, and enables checking fieldSelector and labelSelector fields in authorization webhook matchConditions.
CBORServingAndStorage: Enables CBOR as a supported encoding for requests and responses, and as the preferred storage encoding for custom resources.
CloudControllerManagerWebhook: Enable webhooks in cloud controller manager.
ClusterTrustBundle: Enable ClusterTrustBundle objects and kubelet integration.
ClusterTrustBundleProjection: clusterTrustBundle projected volume sources.
ComponentFlagz: Enables the component's flagz endpoint. See zpages for more information.
ComponentSLIs: Enable the /metrics/slis endpoint on Kubernetes components like kubelet, kube-scheduler, kube-proxy, kube-controller-manager, cloud-controller-manager allowing you to scrape health check metrics.
ComponentStatusz: Enables the component's statusz endpoint. See zpages for more information.
ConcurrentWatchObjectDecode: Enable concurrent watch object decoding. This is to avoid starving the API server's watch cache when a conversion webhook is installed.
ConsistentListFromCache:
Enhance Kubernetes API server performance by serving consistent list requests directly from its watch cache, improving scalability and response times. To consistent list from cache Kubernetes requires a newer etcd version (v3.4.31+ or v3.5.13+), that includes fixes to watch progress request feature. If older etcd version is provided Kubernetes will automatically detect it and fallback to serving consistent reads from etcd. Progress notifications ensure watch cache is consistent with etcd while reducing the need for resource-intensive quorum reads from etcd.

See the Kubernetes documentation on Semantics for get and list for more details.
ContainerCheckpoint: Enables the kubelet checkpoint API. See Kubelet Checkpoint API for more details.
ContextualLogging: Enables extra details in log output of Kubernetes components that support contextual logging.

DefaultHostNetworkHostPortsInPodTemplates:
This feature gate controls the point at which a default value for .spec.containers[*].ports[*].hostPort is assigned, for Pods using hostNetwork: true. The default since Kubernetes v1.28 is to only set a default value in Pods.

Enabling this means a default will be assigned even to the .spec of an embedded PodTemplate (for example, in a Deployment), which is the way that older releases of Kubernetes worked. You should migrate your code so that it does not rely on the legacy behavior.
DevicePluginCDIDevices: Enable support to CDI device IDs in the Device Plugin API.
DisableAllocatorDualWrite:
You can enable the MultiCIDRServiceAllocator feature gate. The API server supports migration from the old bitmap ClusterIP allocators to the new IPAddress allocators.

The API server performs a dual-write on both allocators. This feature gate disables the dual write on the new Cluster IP allocators; you can enable this feature gate if you have completed the relevant stage of the migration.
DisableCloudProviders:
Enabling this feature gate deactivated functionality in kube-apiserver, kube-controller-manager and kubelet that related to the --cloud-provider command line argument.

In Kubernetes v1.31 and later, the only valid values for --cloud-provider are the empty string (no cloud provider integration), or "external" (integration via a separate cloud-controller-manager).
DisableKubeletCloudCredentialProviders: Enabling the feature gate deactivated the legacy in-tree functionality within the kubelet, that allowed the kubelet to to authenticate to a cloud provider container registry for container image pulls.
DisableNodeKubeProxyVersion: Disable setting the kubeProxyVersion field of the Node.
DRAAdminAccess:
Enables support for requesting admin access in a ResourceClaim. A ResourceClaim with admin access grants access to devices which are in use and may enable additional access permissions when making the device available in a container.

This feature gate has no effect unless you also enable the DynamicResourceAllocation feature gate.
DRAResourceClaimDeviceStatus: Enables support the ResourceClaim.status.devices field and for setting this status from DRA drivers.
DynamicResourceAllocation: Enables support for resources with custom parameters and a lifecycle that is independent of a Pod. Allocation of resources is handled by the Kubernetes scheduler based on "structured parameters".
EfficientWatchResumption: Allows for storage-originated bookmark (progress notify) events to be delivered to the users. This is only applied to watch operations.
ElasticIndexedJob: Enables Indexed Jobs to be scaled up or down by mutating both spec.completions and spec.parallelism together such that spec.completions == spec.parallelism. See docs on elastic Indexed Jobs for more details.
EventedPLEG: Enable support for the kubelet to receive container life cycle events from the container runtime via an extension to CRI. (PLEG is an abbreviation for “Pod lifecycle event generator”). For this feature to be useful, you also need to enable support for container lifecycle events in each container runtime running in your cluster. If the container runtime does not announce support for container lifecycle events then the kubelet automatically switches to the legacy generic PLEG mechanism, even if you have this feature gate enabled.
ExecProbeTimeout: Ensure kubelet respects exec probe timeouts. This feature gate exists in case any of your existing workloads depend on a now-corrected fault where Kubernetes ignored exec probe timeouts. See readiness probes.
ExternalServiceAccountTokenSigner: Enable setting --service-account-signing-endpoint to make the kube-apiserver use external signer for token signing and token verifying key management.
GracefulNodeShutdown: Enables support for graceful shutdown in kubelet. During a system shutdown, kubelet will attempt to detect the shutdown event and gracefully terminate pods running on the node. See Graceful Node Shutdown for more details.
GracefulNodeShutdownBasedOnPodPriority: Enables the kubelet to check Pod priorities when shutting down a node gracefully.
HonorPVReclaimPolicy: Honor persistent volume reclaim policy when it is Delete irrespective of PV-PVC deletion ordering. For more details, check the PersistentVolume deletion protection finalizer documentation.

JobPodFailurePolicy: Allow users to specify handling of pod failures based on container exit codes and pod conditions.
JobPodReplacementPolicy: Allows you to specify pod replacement for terminating pods in a Job
JobSuccessPolicy: Allow users to specify when a Job can be declared as succeeded based on the set of succeeded pods.
KMSv1: Enables KMS v1 API for encryption at rest. See Using a KMS Provider for data encryption for more details.
KubeletCgroupDriverFromCRI: Enable detection of the kubelet cgroup driver configuration option from the CRI. You can use this feature gate on nodes with a kubelet that supports the feature gate and where there is a CRI container runtime that supports the RuntimeConfig CRI call. If both CRI and kubelet support this feature, the kubelet ignores the cgroupDriver configuration setting (or deprecated --cgroup-driver command line argument). If you enable this feature gate and the container runtime doesn't support it, the kubelet falls back to using the driver configured using the cgroupDriver configuration setting. See Configuring a cgroup driver for more details.
KubeletCrashLoopBackOffMax: Enables support for configurable per-node backoff maximums for restarting containers in the CrashLoopBackOff state.
KubeletFineGrainedAuthz: Enable fine-grained authorization for the kubelet's HTTP(s) API.

See resource allocation reporting for more details. with information about the allocatable resources, enabling clients to properly track the free compute resources on a node.
KubeletPodResourcesGet: Enable the Get gRPC endpoint on kubelet's for Pod resources. This API augments the resource allocation reporting.
KubeletSeparateDiskGC: The split image filesystem feature enables kubelet to perform garbage collection of images (read-only layers) and/or containers (writeable layers) deployed on separate filesystems.
KubeletTracing: Add support for distributed tracing in the kubelet. When enabled, kubelet CRI interface and authenticated http servers are instrumented to generate OpenTelemetry trace spans. See Traces for Kubernetes System Components for more details.
KubeProxyDrainingTerminatingNodes: Implement connection draining for terminating nodes for externalTrafficPolicy: Cluster services.
LoadBalancerIPMode: Allows setting ipMode for Services where type is set to LoadBalancer. See Specifying IPMode of load balancer status for more information.
LocalStorageCapacityIsolationFSQuotaMonitoring: When LocalStorageCapacityIsolation is enabled for local ephemeral storage, the backing filesystem for emptyDir volumes supports project quotas, and UserNamespacesSupport is enabled, project quotas are used to monitor emptyDir volume storage consumption rather than using filesystem walk, ensuring better performance and accuracy.

OpenAPIEnums: Enables populating "enum" fields of OpenAPI schemas in the spec returned from the API server.
PDBUnhealthyPodEvictionPolicy: Enables the unhealthyPodEvictionPolicy field of a PodDisruptionBudget. This specifies when unhealthy pods should be considered for eviction. Please see Unhealthy Pod Eviction Policy for more details.
PersistentVolumeLastPhaseTransitionTime: Adds a new field to PersistentVolume which holds a timestamp of when the volume last transitioned its phase.
PodAndContainerStatsFromCRI: Configure the kubelet to gather container and pod stats from the CRI container runtime rather than gathering them from cAdvisor. As of 1.26, this also includes gathering metrics from CRI and emitting them over /metrics/cadvisor (rather than having cAdvisor emit them directly).
PodDeletionCost: Enable the Pod Deletion Cost feature which allows users to influence ReplicaSet downscaling order.
PodDisruptionConditions: Enables support for appending a dedicated pod condition indicating that the pod is being deleted due to a disruption.
PodIndexLabel: Enables the Job controller and StatefulSet controller to add the pod index as a label when creating new pods. See Job completion mode docs and StatefulSet pod index label docs for more details.
PodLevelResources: Enable Pod level resources: the ability to specify resource requests and limits at the Pod level, rather than only for specific containers.
PodLifecycleSleepAction: Enables the sleep action in Container lifecycle hooks.
PodLifecycleSleepActionAllowZero: Enables setting zero value for the sleep action in container lifecycle hooks.
PodLogsQuerySplitStreams: Enable fetching specific log streams (either stdout or stderr) from a container's log streams, using the Pod API.
PodReadyToStartContainersCondition:
Enable the kubelet to mark the PodReadyToStartContainers condition on pods.

This feature gate was previously known as PodHasNetworkCondition, and the associated condition was named PodHasNetwork.
PodSchedulingReadiness: Enable setting schedulingGates field to control a Pod's scheduling readiness.
PortForwardWebsockets: Allow WebSocket streaming of the portforward sub-protocol (port-forward) from clients requesting version v2 (v2.portforward.k8s.io) of the sub-protocol.
PreferAlignCpusByUncoreCache: When PreferAlignCpusByUncoreCache is enabled while the CPU Manager Policy is set to static, containers within a Guaranteed pod will individually be aligned to an uncore cache group at a best-effort policy. This feature can optimize performance for certain cache-sensitive workloads by minimizing the cpu allocation across uncore caches.
ProcMountType: Enables control over the type proc mounts for containers by setting the procMount field of a Pod's securityContext.
QOSReserved: Allows resource reservations at the QoS level preventing pods at lower QoS levels from bursting into resources requested at higher QoS levels (memory only for now).
RecoverVolumeExpansionFailure: Enables users to edit their PVCs to smaller sizes so as they can recover from previously issued volume expansion failures. See Recovering from Failure when Expanding Volumes for more details.
RecursiveReadOnlyMounts: Enables support for recursive read-only mounts. For more details, see read-only mounts.
RelaxedEnvironmentVariableValidation: Allow almost all printable ASCII characters in environment variables.
ReloadKubeletServerCertificateFile:
Enable the kubelet TLS server to update its certificate if the specified certificate file are changed.

This feature is useful when specifying tlsCertFile and tlsPrivateKeyFile in kubelet configuration. The feature gate has no effect for other cases such as using TLS boostrap.
RemainingItemCount: Allow the API servers to show a count of remaining items in the response to a chunking list request.
ResilientWatchCacheInitialization: Enables resilient watchcache initialization to avoid controlplane overload.
ResourceHealthStatus: Enable the allocatedResourcesStatus field within the .status for a Pod. The field reports additional details for each container in the Pod, with the health information for each device assigned to the Pod. See Device plugin and unhealthy devices for more details.
RetryGenerateName:
Enables retrying of object creation when the API server is expected to generate a name.

When this feature is enabled, requests using generateName are retried automatically in case the control plane detects a name conflict with an existing object, up to a limit of 8 total attempts.
RotateKubeletServerCertificate: Enable the rotation of the server TLS certificate on the kubelet. See kubelet configuration for more details.
RuntimeClassInImageCriApi: Enables images to be pulled based on the runtime class of the pods that reference them.
SchedulerAsyncPreemption: Enable running some expensive operations within the scheduler, associated with preemption, asynchronously. Asynchronous processing of preemption improves overall Pod scheduling latency.
SchedulerQueueingHints: Enables the scheduler's queueing hints feature, which benefits to reduce the useless requeueing. The scheduler retries scheduling pods if something changes in the cluster that could make the pod scheduled. Queueing hints are internal signals that allow the scheduler to filter the changes in the cluster that are relevant to the unscheduled pod, based on previous scheduling attempts.
SELinuxChangePolicy:
Enables spec.securityContext.seLinuxChangePolicy field. This field can be used to opt-out from applying the SELinux label to the pod volumes using mount options. This is required when a single volume that supports mounting with SELinux mount option is shared between Pods that have different SELinux labels, such as a privileged and unprivileged Pods.

Enabling the SELinuxChangePolicy feature gate requires the feature gate SELinuxMountReadWriteOncePod to be enabled.
SELinuxMount:
Speeds up container startup by allowing kubelet to mount volumes for a Pod directly with the correct SELinux label instead of changing each file on the volumes recursively. It widens the performance improvements behind the SELinuxMountReadWriteOncePod feature gate by extending the implementation to all volumes.

Enabling the SELinuxMount feature gate requires the feature gates SELinuxMountReadWriteOncePod and SELinuxChangePolicy to be enabled.
SELinuxMountReadWriteOncePod: Speeds up container startup by allowing kubelet to mount volumes for a Pod directly with the correct SELinux label instead of changing each file on the volumes recursively. The initial implementation focused on ReadWriteOncePod volumes.
SeparateTaintEvictionController: Enables running TaintEvictionController, that performs Taint-based Evictions, in a controller separated from NodeLifecycleController. When this feature is enabled, users can optionally disable Taint-based Eviction setting the --controllers=-taint-eviction-controller flag on the kube-controller-manager.
ServiceAccountTokenJTI: Controls whether JTIs (UUIDs) are embedded into generated service account tokens, and whether these JTIs are recorded into the Kubernetes audit log for future requests made by these tokens.
ServiceAccountTokenNodeBinding: Controls whether the API server allows binding service account tokens to Node objects.
ServiceAccountTokenNodeBindingValidation: Controls whether the apiserver will validate a Node reference in service account tokens.
ServiceAccountTokenPodNodeInfo: Controls whether the apiserver embeds the node name and uid for the associated node when issuing service account tokens bound to Pod objects.
ServiceTrafficDistribution: Allows usage of the optional spec.trafficDistribution field in Services. The field offers a way to express preferences for how traffic is distributed to Service endpoints.
SidecarContainers: Allow setting the restartPolicy of an init container to Always so that the container becomes a sidecar container (restartable init containers). See Sidecar containers and restartPolicy for more details.
SizeMemoryBackedVolumes: Enable kubelets to determine the size limit for memory-backed volumes (mainly emptyDir volumes).
StatefulSetAutoDeletePVC: Allows the use of the optional .spec.persistentVolumeClaimRetentionPolicy field, providing control over the deletion of PVCs in a StatefulSet's lifecycle. See PersistentVolumeClaim retention for more details.

TopologyManagerPolicyBetaOptions: Allow fine-tuning of topology manager policies, experimental, Beta-quality options. This feature gate guards a group of topology manager options whose quality level is beta. This feature gate will never graduate to stable.
TopologyManagerPolicyOptions: Enable fine-tuning of topology manager policies.
TranslateStreamCloseWebsocketRequests: Allow WebSocket streaming of the remote command sub-protocol (exec, cp, attach) from clients requesting version 5 (v5) of the sub-protocol.
UnauthenticatedHTTP2DOSMitigation: Enables HTTP/2 Denial of Service (DoS) mitigations for unauthenticated clients. Kubernetes v1.28.0 through v1.28.2 do not include this feature gate.
UnknownVersionInteroperabilityProxy: Proxy resource requests to the correct peer kube-apiserver when multiple kube-apiservers exist at varied versions. See Mixed version proxy for more information.
UserNamespacesPodSecurityStandards: Enable Pod Security Standards policies relaxation for pods that run with namespaces. You must set the value of this feature gate consistently across all nodes in your cluster, and you must also enable UserNamespacesSupport to use this feature.
UserNamespacesSupport: Enable user namespace support for Pods.
ValidatingAdmissionPolicy: Enable ValidatingAdmissionPolicy support for CEL validations be used in Admission Control.

WatchFromStorageWithoutResourceVersion: Enables watches without resourceVersion to be served from storage.
WatchList: Enable support for streaming initial state of objects in watch requests.
WatchListClient: Allows an API client to request a stream of data rather than fetching a full list. This functionality is available in client-go and requires the WatchList feature to be enabled on the server. If the WatchList is not supported on the server, the client will seamlessly fall back to a standard list request.
WindowsCPUAndMemoryAffinity: Add CPU and Memory Affinity support to Windows nodes with CPUManager, MemoryManager and topology manager.
WindowsGracefulNodeShutdown: Enables support for windows node graceful shutdown in kubelet. During a system shutdown, kubelet will attempt to detect the shutdown event and gracefully terminate pods running on the node. See Graceful Node Shutdown for more details.
WindowsHostNetwork: Enables support for joining Windows containers to a hosts' network namespace.
WinDSR: Allows kube-proxy to create DSR loadbalancers for Windows.
WinOverlay: Allows kube-proxy to run in overlay mode for Windows.

What's next

The deprecation policy for Kubernetes explains the project's approach to removing features and components.
Since Kubernetes 1.24, new beta APIs are not enabled by default. When enabling a beta feature, you will also need to enable any associated API resources. For example, to enable a particular resource like storage.k8s.io/v1beta1/csistoragecapacities, set --runtime-config=storage.k8s.io/v1beta1/csistoragecapacities. See API Versioning for more details on the command line flags.
