接前一篇《CICD搭建之 kubernetes-dashboard》，验证一下从registry拉取镜像部署应用。
还是用nginx进行部署，先重命名
[root@localhost tmp]# docker tag nginx:latest localhost:7501/nginx
推送到私服，并查看一下本地镜像
[root@localhost tmp]# docker push localhost:7501/nginx
The push refers to repository [localhost:7501/nginx]

删除本地镜像

修改部署配置，如下图，修改为我们私服的镜像名。

点击更新，pod会进行滚动更新。
图1.查看pod
如图1和2，查看pod，选择其中一个点击如下图，可以看到更新日志，拉取的镜像为"localhost:7501/nginx"
图2.更新日志
