k8-dashboard从docker私服拉取镜像部署应用

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

[root@localhost tmp]# docker rmi localhost:7501/nginx
Untagged: localhost:7501/nginx:latest
Untagged: localhost:7501/nginx@sha256:416d511ffa63777489af47f250b70d1570e428b67666567085f2bece3571ad83
[root@localhost tmp]# docker images

nginx                                   latest              992e3b7be046        2 days ago          133MB
jenkinsci/blueocean                     1.24.0              8bc6e31b0d6a        6 days ago          755MB

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
