参考说明

https://kubernetes.io/zh/docs/tasks/configure-pod-container/configure-persistent-volume-storage/#create-a-persistentvolume

PV是全局的概念，创建时不需要指定namespae

题目解答

创建文件pv.yaml，文件内容

apiVersion: v1
kind: PersistentVolume
metadata:
  name: app-config
spec:
  capacity:
    storage: 1Gi
  accessModes:
    - ReadWriteMany
  hostPath:
    path: "/srv/app-config"

student@master01:~$ kubectl apply -f pv.yaml 
persistentvolume/app-config created
