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.

Descriptions for removed feature gates

Accelerators

Provided an early form of plugin to enable Nvidia GPU support when using Docker Engine; no longer available. See Device Plugins for an alternative.

AdmissionWebhookMatchConditions

Enable match conditions on mutating & validating admission webhooks.

AdvancedAuditing

Enable advanced auditing

AffinityInAnnotations

Enable setting Pod affinity or anti-affinity.

AggregatedDiscoveryEndpoint

Enable a single HTTP endpoint /discovery/<version> which supports native HTTP caching with ETags containing all APIResources known to the API server.

AllowExtTrafficLocalEndpoints

Enable a service to route external requests to node local endpoints.

AllowInsecureBackendProxy

Enable the users to skip TLS verification of kubelets on Pod log requests.

AllowServiceLBStatusOnNonLB

Enables .status.ingress.loadBalancer to be set on Services of types other than LoadBalancer.

APIListChunking

Enable the API clients to retrieve (LIST or GET) resources from API server in chunks.

APIPriorityAndFairness

Enable managing request concurrency with prioritization and fairness at each server. (Renamed from RequestManagement)

APISelfSubjectReview

Activate the SelfSubjectReview API which allows users to see the requesting subject's authentication information. See API access to authentication information for a client 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.

AttachVolumeLimit

Enable volume plugins to report limits on number of volumes that can be attached to a node. See dynamic volume limits for more details.

BalanceAttachedNodeVolumes

Include volume count on node to be considered for balanced resource allocation while scheduling. A node which has closer CPU, memory utilization, and volume count is favored by the scheduler while making decisions.

BlockVolume

Enable the definition and consumption of raw block devices in Pods. See Raw Block Volume Support for more details.

BoundServiceAccountTokenVolume

Migrate ServiceAccount volumes to use a projected volume consisting of a ServiceAccountTokenVolumeProjection. Cluster admins can use metric serviceaccount_stale_tokens_total to monitor workloads that are depending on the extended tokens. If there are no such workloads, turn off extended tokens by starting kube-apiserver with flag --service-account-extend-token-expiration=false.

Check Bound Service Account Tokens for more details.

CloudDualStackNodeIPs

Enables dual-stack kubelet --node-ip with external cloud providers. See Configure IPv4/IPv6 dual-stack for more details.

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.

ConfigurableFSGroupPolicy

Allows user to configure volume permission change policy for fsGroups when mounting a volume in a Pod. See Configure volume permission and ownership change policy for Pods for more details.

ConsistentHTTPGetHandlers

Normalize HTTP get URL and Header passing for lifecycle handlers with probers.

ControllerManagerLeaderMigration

Enables Leader Migration for kube-controller-manager and cloud-controller-manager which allows a cluster operator to live migrate controllers from the kube-controller-manager into an external controller-manager (e.g. the cloud-controller-manager) in an HA cluster without downtime.

CPUManager

Enable container level CPU affinity support, see CPU Management Policies.

CRIContainerLogRotation

Enable container log rotation for CRI container runtime. The default max size of a log file is 10MB and the default max number of log files allowed for a container is 5. These values can be configured in the kubelet config. See logging at node level for more details.

CronJobControllerV2

Use an alternative implementation of the CronJob controller. Otherwise, version 1 of the same controller is selected.

CronJobTimeZone

Allow the use of the timeZone optional field in CronJobs

CSIBlockVolume

Enable external CSI volume drivers to support block storage. See csi raw block volume support for more details.

CSIDriverRegistry

Enable all logic related to the CSIDriver API object in csi.storage.k8s.io.

CSIInlineVolume

Enable CSI Inline volumes support for pods.

CSIMigration

Enables shims and translation logic to route volume operations from in-tree plugins to corresponding pre-installed CSI plugins

CSIMigrationAWS

Enables shims and translation logic to route volume operations from the AWS-EBS in-tree plugin to EBS CSI plugin. Supports falling back to in-tree EBS plugin for mount operations to nodes that have the feature disabled or that do not have EBS CSI plugin installed and configured. Does not support falling back for provision operations, for those the CSI plugin must be installed and configured.

CSIMigrationAWSComplete

Stops registering the EBS in-tree plugin in kubelet and volume controllers and enables shims and translation logic to route volume operations from the AWS-EBS in-tree plugin to EBS CSI plugin. Requires CSIMigration and CSIMigrationAWS feature flags enabled and EBS CSI plugin installed and configured on all nodes in the cluster. This flag has been deprecated in favor of the InTreePluginAWSUnregister feature flag which prevents the registration of in-tree EBS plugin.

CSIMigrationAzureDisk

Enables shims and translation logic to route volume operations from the Azure-Disk in-tree plugin to AzureDisk CSI plugin. Supports falling back to in-tree AzureDisk plugin for mount operations to nodes that have the feature disabled or that do not have AzureDisk CSI plugin installed and configured. Does not support falling back for provision operations, for those the CSI plugin must be installed and configured. Requires CSIMigration feature flag enabled.

CSIMigrationAzureDiskComplete

Stops registering the Azure-Disk in-tree plugin in kubelet and volume controllers and enables shims and translation logic to route volume operations from the Azure-Disk in-tree plugin to AzureDisk CSI plugin. Requires CSIMigration and CSIMigrationAzureDisk feature flags enabled and AzureDisk CSI plugin installed and configured on all nodes in the cluster. This flag has been deprecated in favor of the InTreePluginAzureDiskUnregister feature flag which prevents the registration of in-tree AzureDisk plugin.

CSIMigrationAzureFile

Enables shims and translation logic to route volume operations from the Azure-File in-tree plugin to AzureFile CSI plugin. Supports falling back to in-tree AzureFile plugin for mount operations to nodes that have the feature disabled or that do not have AzureFile CSI plugin installed and configured.
