建立一個使用 pv/pvc 的範例工作負載​

apiVersion: v1
kind: Pod
metadata:
  name: my-cinder-pv-pod-1
spec:
  volumes:
    - name: my-cinder-pv-storage-1
      persistentVolumeClaim:
        claimName: pv
  containers:
    - name: task-pv-container-1
      image: nginx
      ports:
        - containerPort: 80
          name: "http-server"
      volumeMounts:
        - mountPath: "/usr/share/nginx/html"
          name: my-cinder-pv-storage-1

進入您的工作負載 shell 並檢查​
