Uninstalling the StatefulSet Workload

Bash
    
 
helm uninstall lb-csi-workload-sts
Copy

Verify that StatefulSet and PODs resources are gone:

Bash

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:

Bash
    
 
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" deletedpersistentvolumeclaim "test-mnt-example-sts-1" deletedpersistentvolumeclaim "test-mnt-example-sts-2" deleted
Copy

Verify that all resources are gone:

Bash
    
 
kubectl get pv,pvc,podsNo resources found in default namespace.
Copy
