修改容器后重新打包镜像并上传至镜像仓库

下载了Docker镜像，安装后发现与自己需要的功能有差距，尝试修改容器后重新打包镜像，上传至镜像仓库备份

1.查看运行中的容器ID

root@UGREEN-958B:~# docker ps
CONTAINER ID   IMAGE                     COMMAND                  CREATED         STATUS         PORTS     NAMES
81132b889109   oldiy/npc-client:latest   "/bin/sh -c '/npc/np…"   4 minutes ago   Up 4 minutes             npc-client

2.这个容器已经修复了，打包镜像

root@UGREEN-958B:~# docker commit 81132b889109 npc:latest
sha256:e867d10d56895b67afa036cdfd69d75df85012e14524d3043bf22b1f70f1b158

3.查看刚刚打包的镜像，镜像名npc:laster

root@UGREEN-958B:~# docker images
REPOSITORY         TAG       IMAGE ID       CREATED          SIZE
npc                latest    e867d10d5689   45 seconds ago   20.6MB
nginx              latest    92b11f67642b   7 weeks ago      187MB
oldiy/npc-client   latest    2c516b9444b5   5 years ago      8.57MB

4.登陆docker账户

root@UGREEN-958B:/# docker login
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded

5.将打包的镜像标记为新名字qxz5617/npc:latest

1
root@UGREEN-958B:/# docker tag npc:latest qxz5617/npc:latest

6.查看镜像列表，新打包的镜像已经标记好了

root@UGREEN-958B:/# docker images
REPOSITORY    TAG       IMAGE ID       CREATED             SIZE
qxz5617/npc   latest    e867d10d5689   About an hour ago   20.6MB
nginx         latest    92b11f67642b   7 weeks ago         187MB
root@UGREEN-958B:/#

7.上传镜像到自己的docker镜像库

root@UGREEN-958B:/# docker push qxz5617/npc:latest
The push refers to repository [docker.io/qxz5617/npc]
f2fcdaf5a2ef: Pushed 
f496aba251ba: Pushed

8.现在可以到自己的docker账户中查看备份的镜像了，收工！
