$ kubectl create -f delete-domain-job.yaml

* Execute `kubectl get all --all-namespaces` to find the name of the `create-weblogic-sample-domain-job`.
* Execute  `kubectl describe pod <name-of-create-weblogic-sample-domain-job>` to see if there is an event that has text similar to `persistentvolumeclaim "domain1-weblogic-sample-pvc" not found`.
* Find the name of the PVC that was created by executing [create-pv-pvc.sh](https://github.com/oracle/weblogic-kubernetes-operator/blob/release/4.0/kubernetes/samples/scripts/create-weblogic-domain-pv-pvc/create-pv-pvc.sh), using `kubectl describe pvc`. It is likely to be `weblogic-sample-pvc`.
* Change the value of `persistentVolumeClaimName` to match the name created when you executed [create-pv-pvc.sh](https://github.com/oracle/weblogic-kubernetes-operator/blob/release/4.0/kubernetes/samples/scripts/create-weblogic-domain-pv-pvc/create-pv-pvc.sh).
* Rerun the `create-domain.sh` script with the same arguments as you did before.
* Verify that the operator is deployed. Use the command:

$ kubectl  get all --all-namespaces

weblogic-operator1   pod/weblogic-operator-

$ create-pv-pvc.sh

$ create-domain.sh
