@ -303,11 +305,13 @@ Each feature gate is designed for enabling/disabling a specific feature:
to discover plugins such as [CSI volume drivers](/docs/concepts/storage/volumes/#csi).
- `KubeletPodResources`: Enable the kubelet's pod resources grpc endpoint.
See [Support Device Monitoring](https://git.k8s.io/community/keps/sig-node/compute-device-assignment.md) for more details.
- `LegacyNodeRoleBehavior`: When disabled, legacy behavior in service load balancers and node disruption will ignore the `node-role.kubernetes.io/master` label in favor of the feature-specific labels.
- `LocalStorageCapacityIsolation`: Enable the consumption of [local ephemeral storage](/docs/concepts/configuration/manage-compute-resources-container/) and also the `sizeLimit` property of an [emptyDir volume](/docs/concepts/storage/volumes/#emptydir).
- `LocalStorageCapacityIsolationFSQuotaMonitoring`: When `LocalStorageCapacityIsolation` is enabled for [local ephemeral storage](/docs/concepts/configuration/manage-compute-resources-container/) and the backing filesystem for [emptyDir volumes](/docs/concepts/storage/volumes/#emptydir) supports project quotas and they are enabled, use project quotas to monitor [emptyDir volume](/docs/concepts/storage/volumes/#emptydir) storage consumption rather than filesystem walk for better performance and accuracy.
- `MountContainers`: Enable using utility containers on host as the volume mounter.
- `MountPropagation`: Enable sharing volume mounted by one container to other containers or pods.
For more details, please see [mount propagation](/docs/concepts/storage/volumes/#mount-propagation).
- `NodeDisruptionExclusion`: Enable use of the node label `node.kubernetes.io/exclude-disruption` which prevents nodes from being evacuated during zone failures.
- `NodeLease`: Enable the new Lease API to report node heartbeats, which could be used as a node health signal.
- `NonPreemptingPriority`: Enable NonPreempting option for PriorityClass and Pod.
- `PersistentLocalVolumes`: Enable the usage of `local` volume type in Pods.

- `ServerSideApply`: Enables the [Sever Side Apply (SSA)](/docs/reference/using-api/api-concepts/#server-side-apply) path at the API Server.
- `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 annotated with "`alpha.service-controller.kubernetes.io/exclude-balancer`" key.
A node is eligible for exclusion if labelled with "`alpha.service-controller.kubernetes.io/exclude-balancer`" key (when `LegacyNodeRoleBehavior` is on) or `node.kubernetes.io/exclude-from-external-load-balancers`.
- `StorageObjectInUseProtection`: Postpone the deletion of PersistentVolume or
PersistentVolumeClaim objects if they are still being used.
- `StorageVersionHash`: Allow apiservers to expose the storage version hash in the discovery.
