Feature Gates (removed)

This page contains list of feature gates that have been removed. The information on this page is for reference. A removed feature gate is different from a GA'ed or deprecated one in that a removed one is no longer recognized as a valid feature gate. However, a GA'ed or a deprecated feature gate is still recognized by the corresponding Kubernetes components although they are unable to cause any behavior differences in a cluster.

For feature gates that are still recognized by the Kubernetes components, please refer to the Alpha/Beta feature gate table or the Graduated/Deprecated feature gate table

Feature gates that are removed

In the following table:

The "From" column contains the Kubernetes release when a feature is introduced or its release stage is changed.
The "To" column, if not empty, contains the last Kubernetes release in which you can still use a feature gate. If the feature stage is either "Deprecated" or "GA", the "To" column is the Kubernetes release when the feature is removed.

SecurityContextDeny: This gate signals that the SecurityContextDeny admission controller is deprecated.
SelectorIndex: Allows label and field based indexes in API server watch cache to accelerate list operations.
ServiceAccountIssuerDiscovery: Enable OIDC discovery endpoints (issuer and JWKS URLs) for the service account issuer in the API server. See Configure Service Accounts for Pods for more details.
ServiceAppProtocol: Enables the appProtocol field on Services and Endpoints.
ServiceInternalTrafficPolicy: Enables the internalTrafficPolicy field on Services
ServiceIPStaticSubrange: Enables a strategy for Services ClusterIP allocations, whereby the ClusterIP range is subdivided. Dynamic allocated ClusterIP addresses will be allocated preferently from the upper range allowing users to assign static ClusterIPs from the lower range with a low risk of collision. See Avoiding collisions for more details.
ServiceLBNodePortControl: Enables the allocateLoadBalancerNodePorts field on Services.
ServiceLoadBalancerClass: Enables the loadBalancerClass field on Services. See Specifying class of load balancer implementation for more details.
ServiceLoadBalancerFinalizer: Enable finalizer protection for Service load balancers.
ServiceNodeExclusion: Enable the exclusion of nodes from load balancers created by a cloud provider. A node is eligible for exclusion if labelled with "node.kubernetes.io/exclude-from-external-load-balancers".
ServiceNodePortStaticSubrange: Enables the use of different port allocation strategies for NodePort Services. For more details, see reserve NodePort ranges to avoid collisions.
ServiceTopology: Enable service to route traffic based upon the Node topology of the cluster.
SetHostnameAsFQDN: Enable the ability of setting Fully Qualified Domain Name(FQDN) as the hostname of a pod. See Pod's setHostnameAsFQDN field.
SkipReadOnlyValidationGCE: Skip validation that GCE PersistentDisk volumes are in read-only mode.
StartupProbe: Enable the startup probe in the kubelet.
StatefulSetMinReadySeconds: Allows minReadySeconds to be respected by the StatefulSet controller.
StorageObjectInUseProtection: Postpone the deletion of PersistentVolume or PersistentVolumeClaim objects if they are still being used.
StreamingProxyRedirects: Instructs the API server to intercept (and follow) redirects from the backend (kubelet) for streaming requests. Examples of streaming requests include the exec, attach and port-forward requests.
SupportIPVSProxyMode: Enable providing in-cluster service load balancing using IPVS. See service proxies for more details.
SupportNodePidsLimit: Enable the support to limiting PIDs on the Node. The parameter pid=<number> in the --system-reserved and --kube-reserved options can be specified to ensure that the specified number of process IDs will be reserved for the system as a whole and for Kubernetes system daemons respectively.
SupportPodPidsLimit: Enable the support to limiting PIDs in Pods.
SuspendJob: Enable support to suspend and resume Jobs. For more details, see the Jobs docs.
Sysctls: Enable support for namespaced kernel parameters (sysctls) that can be set for each pod. See sysctls for more details.
TaintBasedEvictions: Enable evicting pods from nodes based on taints on Nodes and tolerations on Pods. See taints and tolerations for more details.
TaintNodesByCondition: Enable automatic tainting nodes based on node conditions.
TokenRequest: Enable the TokenRequest endpoint on service account resources.
TokenRequestProjection: Enable the injection of service account tokens into a Pod through a projected volume.
TopologyManager: Enable a mechanism to coordinate fine-grained hardware resource assignments for different components in Kubernetes. See Control Topology Management Policies on a node.
TTLAfterFinished: Allow a TTL controller to clean up resources after they finish execution.
UserNamespacesStatelessPodsSupport: Enable user namespace support for stateless Pods. This feature gate was superseded by the UserNamespacesSupport feature gate in the Kubernetes v1.28 release.
ValidateProxyRedirects: This flag controls whether the API server should validate that redirects are only followed to the same host. Only used if the StreamingProxyRedirects flag is enabled.
VolumePVCDataSource: Enable support for specifying an existing PVC as a DataSource.
VolumeScheduling: Enable volume topology aware scheduling and make the PersistentVolumeClaim (PVC) binding aware of scheduling decisions. It also enables the usage of local volume type when used together with the PersistentLocalVolumes feature gate.
VolumeSnapshotDataSource: Enable volume snapshot data source support.
VolumeSubpath: Allow mounting a subpath of a volume in a container.
VolumeSubpathEnvExpansion: Enable subPathExpr field for expanding environment variables into a subPath.
WarningHeaders: Allow sending warning headers in API responses.
WindowsEndpointSliceProxying: When enabled, kube-proxy running on Windows will use EndpointSlices as the primary data source instead of Endpoints, enabling scalability and performance improvements. See Enabling Endpoint Slices.
WindowsGMSA: Enables passing of GMSA credential specs from pods to container runtimes.
WindowsHostProcessContainers: Enables support for Windows HostProcess containers.
WindowsRunAsUserName: Enable support for running applications in Windows containers with as a non-default user. See Configuring RunAsUserName for more details.
