= StorageClass annotations

To set a StorageClass as the cluster-wide default, add
the following annotation to your StorageClass's metadata:

[source,yaml]
----
storageclass.kubernetes.io/is-default-class: "true"
----

For example:

[source,yaml]
----
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  annotations:
    storageclass.kubernetes.io/is-default-class: "true"
...
----

This enables any Persistent Volume Claim (PVC) that does not specify a
specific StorageClass to automatically be provisioned through the
default StorageClass.

[NOTE]
====
The beta annotation `storageclass.beta.kubernetes.io/is-default-class` is
still working; however, it will be removed in a future release.
====

To set a StorageClass description, add the following annotation
to your StorageClass's metadata:

[source,yaml]
----
kubernetes.io/description: My StorageClass Description
----

For example:

[source,yaml]
----
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  annotations:
    kubernetes.io/description: My StorageClass Description
...
----
