Changing the default StorageClass

If you are using AWS, use the following process to change the default StorageClass. This process assumes you have two StorageClasses defined, gp2 and standard, and you want to change the default StorageClass from gp2 to standard.

1. List the StorageClass:

   $ oc get storageclass
   
   NAME                 TYPE
   gp2 (default)        kubernetes.io/aws-ebs (1)
   standard             kubernetes.io/aws-ebs

   1. (default) denotes the default StorageClass.

2. Change the value of the annotation storageclass.kubernetes.io/is-default-class to false for the default StorageClass:

   $ oc patch storageclass gp2 -p '{"metadata": {"annotations": {"storageclass.kubernetes.io/is-default-class": "false"}}}'

3. Make another StorageClass 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"}}}'

4. Verify the changes:

   $ oc get storageclass
   
   NAME                 TYPE
   gp2                  kubernetes.io/aws-ebs
   standard (default)   kubernetes.io/aws-ebs
