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).
- `NamespaceDefaultLabelName`: Enable the API Server to create a default label `kubernetes.io/metadata.name` in all namespaces containing the namespace name.
- `NetworkPolicyEndPort`: Enable use of the field `endPort` in NetworkPolicy objects, allowing the selection of a port range instead of a single port.
- `NodeDisruptionExclusion`: Enable use of the Node label `node.kubernetes.io/exclude-disruption`
which prevents nodes from being evacuated during zone failures.

The Kubelet populates this with `runtime.GOOS` as defined by Go. This can be handy if you are mixing operating systems in your cluster (for example: mixing Linux and Windows nodes).
## kubernetes.io/metadata.name
Example: `kubernetes.io/metadata.name=mynamespace`
Used on: Namespaces
Kubernetes API Server defaults this label to the namespace name during admission. This label can be used with any namespace selector, as an example with NetworkPolicy objects.
## beta.kubernetes.io/arch (deprecated)
This label has been deprecated. Please use `kubernetes.io/arch` instead.
