pod.yaml

kind: Pod
apiVersion: v1
metadata:
  name: jiangbo
spec:
  containers:
    - name: jiangbo
      image: busybox:stable
      command:
        - "/bin/sh"
      args:
        - "-c"
        - "echo 'jiangbo' > /mnt/name.txt"
      volumeMounts:
        - name: nfs-pvc
          mountPath: "/mnt"
  restartPolicy: "Never"
  volumes:
    - name: nfs-pvc

[root@master nfs]# kubectl get pod
NAME      READY   STATUS      RESTARTS   AGE
jiangbo   0/1     Completed   0          90s

查看 nfs

[root@master nfs]# ll

-rw-r--r-- 1 nfsnobody nfsnobody 8 May 30 20:42 name.txt
[root@master nfs]# cat name.txt
jiangbo
[root@master nfs]#
