Docker之发布镜像到DockerHub

如何发布自己的镜像
1、地址https://hub.docker.com/注册自己的账号
2、确定这个账号可以登录

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

Login Succeeded
[root@liuyang ~]#

3、在我们服务器上提交自己的镜像

[root@liuyang dockerfile]# docker tag 67b2d498c93c zhuangbiliuyang/diyliuyang_centos:1.0
[root@liuyang dockerfile]# docker images
REPOSITORY                          TAG       IMAGE ID       CREATED             SIZE
centos_liuyang                      1.6       2c0580c11880   44 minutes ago      
zhuangbiliuyang/diyliuyang_centos   1.0       67b2d498c93c   50 minutes ago      209MB
[root@liuyang dockerfile]# docker push zhuangbiliuyang/diyliuyang_centos:1.0
The push refers to repository [docker.io/zhuangbiliuyang/diyliuyang_centos]

push的时候注意的事项：
1、本地tag没有1.0版本的自己的镜像，重新修改TAG标签：

docker tag 镜像ID 用户名/镜像名:1.0

2、push的时候一定带上版本号
