@@ -675,6 +676,9 @@ Each feature gate is designed for enabling/disabling a specific feature:
- `KubeletPodResources`: Enable the kubelet's pod resources gRPC endpoint. See
[Support Device Monitoring](https://github.com/kubernetes/enhancements/blob/master/keps/sig-node/606-compute-device-assignment/README.md)
for more details.
- `KubeletPodResourcesGetAllocatable`: Enable the kubelet's pod resources `GetAllocatableResources` functionality.
This API augments the [resource allocation reporting](https://kubernetes.io/docs/concepts/extend-kubernetes/compute-storage-net/device-plugins/#monitoring-device-plugin-resources)
with informations about the allocatable resources, enabling clients to properly track the free compute resources on a node.
- `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 provided by `NodeDisruptionExclusion` and `ServiceNodeExclusion`.
