Deploying the StatefulSet Workload

helm install \ --set statefulset.enabled=true \ lb-csi-workload-sts \ lightbits-helm-repo/lb-csi-workload-examples

Will output:

NAME: lb-csi-workload-sts LAST DEPLOYED: Sun Feb 21 16:09:02 2021 NAMESPACE: default STATUS: deployed REVISION: 1 TEST SUITE: None

Verifying the StatefulSet Workload

Verify that the following conditions are met:

  • PV and PVC is Bound

  • PODs status is Running

  • StatefulSet has 3/3 Ready

Uninstalling the StatefulSet Workload

helm uninstall lb-csi-workload-sts

Verify that StatefulSet and PODs resources are gone:

kubectl get pv,pvc,pods,sts NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE persistentvolume/pvc-1a16e8da-427a-47a1-9974-c7f18b9d8abb 10Gi RWO Delete Bound default/test-mnt-example-sts-0 example-sc 5m31s persistentvolume/pvc-57e6e555-43e3-4f39-9433-c287d3ab53d6 10Gi RWO Delete Bound default/test-mnt-example-sts-1 example-sc 5m21s persistentvolume/pvc-945f0393-e711-4c75-b2f9-b80222d346ab 10Gi RWO Delete Bound default/test-mnt-example-sts-2 example-sc 5m10s NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE persistentvolumeclaim/test-mnt-example-sts-0 Bound pvc-1a16e8da-427a-47a1-9974-c7f18b9d8abb 10Gi RWO example-sc 5m32s persistentvolumeclaim/test-mnt-example-sts-1 Bound pvc-57e6e555-43e3-4f39-9433-c287d3ab53d6 10Gi RWO example-sc 5m23s persistentvolumeclaim/test-mnt-example-sts-2 Bound pvc-945f0393-e711-4c75-b2f9-b80222d346ab 10Gi RWO example-sc 5m11s

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.
