3.在我们服务器上提交；

[root@liustudy tomcat]# docker login --help

Usage:  docker login [OPTIONS] [SERVER]

#push镜像问题？
[root@liustudy tomcat]# docker push liusirstudy/diytomcat:1.0
The push refers to repository [docker.io/liusirstudy/diytomcat]
An image does not exist locally with the tag: liusirstudy/diytomcat

解决：增加一个 tag

提交的时候也是按照镜像的层级来提交的。

ps:这里需要注意，docker push 仓库名/镜像：tag；仓库名为账号名，才可以成功上传。
