6.4. Changing the default storage class
If you are using AWS, use the following process to change the default storage class. This process assumes you have two storage classes defined, gp2 and standard, and you want to change the default storage class from gp2 to standard.
List the storage class:
$ oc get storageclass
Example output
NAME TYPE gp2 (default) kubernetes.io/aws-ebs 1 standard kubernetes.io/aws-ebs- 1
(default)denotes the default storage class.
Change the value of the annotation
storageclass.kubernetes.io/is-default-classtofalsefor the default storage class:$ oc patch storageclass gp2 -p '{"metadata": {"annotations": {"storageclass.kubernetes.io/is-default-class": "false"}}}'Make another storage class the default by adding or modifying the annotation as
storageclass.kubernetes.io/is-default-class=true.$ oc patch storageclass standard -p '{"metadata": {"annotations": {"storageclass.kubernetes.io/is-default-class": "true"}}}'Verify the changes:
$ oc get storageclass
Example output
