参考：https://core815.blog.csdn.net/article/details/119535868中，步骤1-3完成镜像构建。

docker login
# 配置tag，DockerHub账号/镜像名称
docker tag sentinel:1.6.3 core815/sentinel:1.6.3
# push
docker push core815/sentinel:1.6.3

apiVersion: apps/v1
kind: Deployment
metadata: 
 name: sentinel-deployment
 labels:
  app: sentinel
spec:
 replicas: 1
 selector:
  matchLabels:
   app: sentinel
 template:
  metadata:
   labels:
    app: sentinel
  spec:
   containers:
    - name: sentinel
      imagePullPolicy: Always # 如果没有此设置，会导致一直不拉取DockerHub最新镜像
      image: core815/sentinel:1.6.3
      ports:
       - containerPort: 9999

apiVersion: v1
kind: Service
metadata: 
 name: sentinel-service
spec:
 type: NodePort
 selector:
  app: sentinel
 ports:
  - name: http
    protocol: TCP
    port: 9999
    targetPort: 9999

执行如下命令创建商品服务的service：

kubectl apply -f sentinel-service.yaml

查看对外暴露端口：

kubectl get svc|grep sentinel
