postgresql - 在Google云平台上的Kubernetes中创建持久卷

我正在尝试将Postgres服务部署到具有持久卷和持久卷声明的Google Cloud kubernetes，以为我的应用程序提供存储。

部署时， pods 卡在CrashLoopBackOff中。

广告连播的事件之一失败，并显示以下消息:
Error: failed to start container "postgres": Error response from daemon: error while creating mount source path '/data/postgres-pv': mkdir /data: read-only file system
这是我尝试使用kubectl部署的Yaml:

kind: PersistentVolume
apiVersion: v1
metadata:
  name: postgres-pv
  labels:
    type: local
    app: postgres
spec:
  capacity:
    storage: 5Gi
  storageClassName: standard
  accessModes:
    - ReadWriteOnce
  hostPath:
    path: /data/postgres-pv
---
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: postgres-pvc
  labels:
    type: local
    app: postgres
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 5Gi

          image: postgres:9.6.6
          env:
            - name: POSTGRES_USER
              valueFrom:
                secretKeyRef:
                  name: postgres-credentials
                  key: user
            - name: POSTGRES_PASSWORD
              valueFrom:
                secretKeyRef:
                  name: postgres-credentials
                  key: password
            - name: POSTGRES_DB
              value: kubernetes_django
          ports:
            - containerPort: 5432
          volumeMounts:
            - mountPath: /var/lib/postgresql/data
              name: postgres-volume-mount
      volumes:
        - name: postgres-volume-mount
          persistentVolumeClaim:
            claimName: postgres-pvc
---
apiVersion: v1
kind: Service
metadata:
  name: postgres
  labels:
    app: postgres
spec:
  ports:
    - protocol: TCP
      port: 5432
      targetPort: 5432
  selector:
   app: postgres

没有部署失败，但是 pods 卡在了CrashLoopBackOff中。

谢谢您的帮助!

问题是您的持久卷。您正在使用不支持的主机路径，并且永远不会支持according to the doc
