我有以下部署：

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: postgres-persistent-volume-claim
      containers:
        - name: postgres
          image: prikshet/postgres
          ports:
            - containerPort: 5432
          volumeMounts:
            - name: postgres-storage
              mountPath: /var/lib/postgresql/data
              subPath: postgres

当我包含第23-26行并执行kubectl apply时，pod会出现错误并且不会运行，但当我删除第23-36行时，pod会运行。我想使用第23-26行创建卷挂载。检查此pod的日志时出现的错误是：

postgres: could not access the server configuration file "/var/lib/postgresql/data/postgresql.conf": No such file or directory

postgres持久卷声明是：

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: postgres-persistent-volume-claim
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi

如何解决这个问题？
