Persistent Volumes (PV) & Storage In Tanzu Community Edition Part 2

In the previous post, we created a PVC. Lets proceed with the next steps.

1.) Create a Pod

The next step is to create a k8s pod which we will attach to our PVC. Use VI to create the pod.yaml file:

ice@tanzu-jumpsrvr01:~$ cat pv-pod.yaml
apiVersion: v1
kind: Pod
metadata:
  name: test-pv-pod
spec:
  volumes:
    - name: task-pv-storage
      persistentVolumeClaim:
        claimName: database-pvc
  containers:
    - name: task-pv-container
      image: nginx
      ports:
        - containerPort: 80
          name: "http-server"
      volumeMounts:
        - mountPath: "/usr/share/nginx/html"
          name: task-pv-storage

Then apply the file to our test namespace:

kubectl apply -f pv-pod.yaml -n storage-test

You will see the ContainerCreating message:

Use the following command to view the pod details:

kubectl describe pod test-pv-pod -n storage-test

Use the following command to connect to our pod:

kubectl exec -it -n storage-test test-pv-pod -- /bin/bash

Our pod is now connected to the PV:

1.) Delete the pod and PVC

To delete the pod that we just made, run this command:

kubectl delete pod test-pv-pod -n storage-test

And then run the following commands to delete the PV and PVC. (Deleting the PVC will automatically delete the PV).

kubectl delete pvc -n storage-test database-pvc

Deleting the PVC automatically deletes the objects in vCenter.
