If you would like to see the feature in action and verify it works fine in your cluster here's what you can try:
1. Define a basic PersistentVolumeClaim:
```yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: pvc-1
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 1Gi
```
```yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: pvc-1
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 1Gi
```
2. Create the PersistentVolumeClaim when there is no default StorageClass. The PVC won't provision or bind (unless there is an existing, suitable PV already present) and will remain in <code>Pending</code> state.
```
$ kc get pvc
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
pvc-1 Pending
```
```
$ kc get pvc
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
pvc-1 Pending
```
3. Configure one StorageClass as default.
```
$ kc patch sc -p '{"metadata":{"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
storageclass.storage.k8s.io/my-storageclass patched
```
```
$ kc patch sc -p '{"metadata":{"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
storageclass.storage.k8s.io/my-storageclass patched
```
4. Verify that PersistentVolumeClaims is now provisioned correctly and was updated retroactively with new default StorageClass.
```
$ kc get pvc
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
pvc-1 Bound pvc-06a964ca-f997-4780-8627-b5c3bf5a87d8 1Gi RWO my-storageclass 87m
```
```
$ kc get pvc
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
pvc-1 Bound pvc-06a964ca-f997-4780-8627-b5c3bf5a87d8 1Gi RWO my-storageclass 87m
```
