==========================================================
运行一个测试示例--在master节点先安装docker服务
创建一个Nginx Web，判断集群是否正常工
# /opt/kubernetes/bin/kubectl run nginx --image=daocloud.io/nginx --replicas=3
# /opt/kubernetes/bin/kubectl expose deployment nginx --port=88 --target-port=80 --type=NodePort
​
在master上面查看：
查看Pod，Service：
# /opt/kubernetes/bin/kubectl get pods  #需要等一会
NAME                                 READY     STATUS    RESTARTS   AGE

​
查看pod详细信息：
# /opt/kubernetes/bin/kubectl describe pod nginx-64f497f8fd-fjgt2
​
# /opt/kubernetes/bin/kubectl get svc

​
访问nodeip加端口
打开浏览器输入：http://192.168.246.164:38696•
​
恭喜你，集群部署成功！
