When you request storage with a
PersistentVolumeClaim
(PVC), you can specify a StorageClass. If you do not specify a StorageClass, the
default StorageClass is used if one is configured in the cluster.
Google Distributed Cloud does not configure a default StorageClass. For example,
suppose you create a PVC that does not specify a StorageClass. The volume
controller will fulfill the claim according to the default StorageClass.
Changing the default StorageClass
As a cluster administrator, you might want to change the default storage class.
Then all requests for storage that do not specify a StorageClass will be
fulfilled according to the StorageClass of your choice. This section gives the
steps for changing the default.
Deploy a new storage system
Deploy a new storage system and any software components for integrating the new
storage mechanism with a Kubernetes cluster. For example, you might need to
install a CSI driver
in the cluster.
Mark any existing default StorageClass as non-default
Search your cluster for any existing default StorageClass if one already exists
and mark it as non-default. For details, see
Change the default StorageClass.
