Question

我是新来的kubernetes和东西。我正在阅读教程，在使用pstgres数据库和持久卷声明时遇到错误。我很确定所有权限都已授予用户，但错误仍然表明该文件夹拥有错误的所有权。

这是我的配置文件

这是永久性批量声明文件

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: database-persistent-volume-claim
spec:
  accessModes: 
    - ReadWriteOnce
  resources:
    requests:
      storage: 2Gi

这是我的postgres部署文件

apiVersion: apps/v1
kind: Deployment
metadata: 
  name: postgres-deployment
spec:
  replicas: 1
  selector:
    matchLabels: 
      component: postgres
  template: 
     metadata:
       labels:
         component: postgres
     spec:
       volumes:
        - name: postgres-storage
          persistentVolumeClaim:
            claimName: database-persistent-volume-claim
       containers:
         - name: postgres
           image: postgres
           ports:
             - containerPort: 5432
           volumeMounts:
             - name: postgres-storage
               mountPath: /var/lib/postgresql/data
               subPath: postgres
           env:
             - name: POSTGRES_HOST_AUTH_METHOD
               value: "trust"
             - name: PGPASSWORD
               valueFrom:
                 secretKeyRef:
                   name: pgpassword
                   key: PGPASSWORD

Here is the error message 
2020-04-12 01:57:11.986 UTC [82] FATAL:  data directory "/var/lib/postgresql/data" has wrong ownership
2020-04-12 01:57:11.986 UTC [82] HINT:  The server must be started by the user that owns the data directory.
child process exited with exit code 1
initdb: removing contents of data directory "/var/lib/postgresql/data"

有什么帮助吗？

这对我来说很有用，请检查卷安装中的子路径

apiVersion: apps/v1
    kind: StatefulSet
    metadata:
