容器之上传镜像到Docker hub

    Docker hub在国内能够访问，首先要建立一个帐号，这个后面会用到，我是用126邮箱注册的。

1. docker login

    List-1 Username不能使用你注册的邮箱，要用使用注册时用的username；要输入密码

mjduan@mjduandeMacBook-Pro:/tmp % docker login
Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one.
Username: mjduan
Password:
Login Succeeded

2.docker push

    List-2 docker push

mjduan@mjduandeMacBook-Pro:/tmp % docker push mjduan/helloworld:1.0
The push refers to repository [docker.io/mjduan/helloworld]
be49a4cca8c8: Pushed
35c20f26d188: Pushed
c3fe59dd9556: Pushed

    注意，要注意镜像名称的格式，格式要是{username}/imageNamge:1.0，这个username是你注册时的那个username，如List-2中所示，这样才能push到docker hub，否则会报以下List-3中所示的错误，这个地方我是google/bing.cn搜索以后解决的。

    List-3 镜像名称格式缘由致使报错

mjduan@mjduandeMacBook-Pro:/tmp % docker push helloworld:1.0
The push refers to repository [docker.io/library/helloworld]

3.查看Docker hub的变化，以下

4.docker logout

    List-4 退出

mjduan@mjduandeMacBook-Pro:/tmp % docker logout
