容器之上傳鏡像到Docker hub

    Docker hub在國內能夠訪問，首先要建立一個帳號，這個後面會用到，我是用126郵箱註冊的。

1. docker login

    List-1 Username不能使用你註冊的郵箱，要用使用註冊時用的username；要輸入密碼

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
6ed1a81ba5b6: Pushed
a3483ce177ce: Pushed
ce6c8756685b: Pushed
30339f20ced0: Pushed
0eb22bfb707d: Pushed
a2ae92ffcd29: Pushed

    注意，要注意鏡像名稱的格式，格式要是{username}/imageNamge:1.0，這個username是你註冊時的那個username，如List-2中所示，這樣才能push到docker hub，否則會報以下List-3中所示的錯誤，這個地方我是google/bing.cn搜索以後解決的。

    List-3 鏡像名稱格式緣由致使報錯

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

3.查看Docker hub的變化，以下

4.docker logout

    List-4 退出

mjduan@mjduandeMacBook-Pro:/tmp % docker logout
