11 发布自己的镜像

发布到docker hub

1、地址https://hub.docker.com/注册账号
2、确定账号正常登陆
3、在我们服务器上提交自己的镜像

# 查看login命令
[hekai@localhost ~]$ docker login --help

Usage:  docker login [OPTIONS] [SERVER]

Log in to a Docker registry.
If no server is specified, the default is defined by the daemon.

Options:
  -p, --password string   Password
      --password-stdin    Take the password from stdin
  -u, --username string   Username

4、登陆完成后就可以提交镜像了

[hekai@localhost ~]$ docker login -u cyano01
Password:
WARNING! Your password will be stored unencrypted in /home/hekai/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded
[hekai@localhost ~]$ 

一步docker push

# 直接push会被拒绝
[hekai@localhost ~]$ docker push diytomcat
Using default tag: latest
The push refers to repository [docker.io/library/diytomcat]

# push镜像的问题？
[hekai@localhost ~]$ docker push cyano01/diytomcat:1.0
The push refers to repository [docker.io/cyano01/diytomcat]
An image does not exist locally with the tag: cyano01/diytomcat
[hekai@localhost ~]$ 

# 解决：增加一个tag
[hekai@localhost ~]$ docker tag 5f53b8346cfd cyano01/tomcat:1.0
[hekai@localhost ~]$ docker images
REPOSITORY            TAG       IMAGE ID       CREATED         SIZE
diytomcat             latest    5f53b8346cfd   10 hours ago    665MB
cyano01/tomcat        1.0       5f53b8346cfd   10 hours ago    665MB

# 尽量带上版本号
[hekai@localhost ~]$ docker push cyano01/tomcat:1.0
The push refers to repository [docker.io/cyano01/tomcat]
e167e05de1b5: Pushing [===================>                               ]  22.18MB/58.2MB

8a26f9bbd84d: Pushing [=>                                                 ]  9.308MB/381.7MB
62e4a193e44f: Pushed

可以发现，提交的时候也是按照镜像的层级来进行提交的
