我正在跟随LesJackson的tutorial到微服务，在为ms sql服务器创建部署时，我在05：30：00卡住了。我已经编写了部署文件，正如yt视频中所示：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: mssql-depl
spec:
  replicas: 1
  selector:
    matchLabels:
      app: mssql
  template:

    spec:

          ports:
            - containerPort: 1433
          env:
          - name: MSSQL_PID
            value: "Express"
          - name: ACCEPT_EULA
            value: "Y"
          - name: SA_PASSWORD
            valueFrom:
              secretKeyRef:
                name: mssql
                key: SA_PASSWORD
          volumeMounts:
            - mountPath: /var/opt/mssql/data
              name: mssqldb
      volumes:
      - name: mssqldb
        persistentVolumeClaim:
          claimName: mssql-claim

---
apiVersion: v1
kind: Service
metadata:
  name: mssql-clusterip-srv
spec:
  type: ClusterIP
  selector:
    app: mssql
  ports:
  - name: mssql
    protocol: TCP
    port: 1433 # this is default port for mssql
    targetPort: 1433 

---
apiVersion: v1
kind: Service
metadata:
  name: mssql-loadbalancer
spec:
  type: LoadBalancer
  selector:
    app: mssql
  ports:
  - protocol: TCP
    port: 1433 # this is default port for mssql
   targetPort: 1433

《持久卷》宣称：

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: mssql-claim
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 200Mi

但是，当我应用此部署时，Pod以ImagePullBackOff状态结束：

在事件中它显示
“rpc错误：code =未知desc =超过上下文截止时间”
但它并没有告诉我任何东西，有关解决此错误的资源也不包括此类错误。
我在本地使用docker上的kubernetes。我已经研究过这个问题，当从一个私人注册表中拉图像时会发生，但这是一个公共的，正确的here。我复制粘贴图像路径以确保，我尝试了不同的ms sql版本，但没有效果。
有没有人能这么好心，告诉我我应该走的正确方向/我应该尝试什么才能让这个工作？它在视频中工作得很好：（
