Since the default StorageClass.reclaimPolicy is Retain, the PVCs and PVs will remain and will not be deleted.

In order to delete them, run the following:

kubectl delete \

persistentvolumeclaim/test-mnt-example-sts-0 \

persistentvolumeclaim/test-mnt-example-sts-1 \

persistentvolumeclaim/test-mnt-example-sts-2

persistentvolumeclaim "test-mnt-example-sts-0" deleted

persistentvolumeclaim "test-mnt-example-sts-1" deleted

persistentvolumeclaim "test-mnt-example-sts-2" deleted

Verify that all resources are gone:

kubectl get pv,pvc,pods

No resources found in default namespace.
