如何push一个docker镜像到DockerHub上

 

在DockerHub上创建账号：https://hub.docker.com/

这里我的账号是firewarm

本地下载镜像（这里拿alpine做示例）,并为镜像打tag

[root@host-30 ~]# docker pull alpine:3.4

[root@host-30 ~]# docker tag alpine:3.4 firewarm/alpine:3.4

登录到DockerHub上

[root@host-30 ~]# docker login

# 输入用户名和密码

push镜像到DockerHub上

[root@host-30 ~]# docker push firewarm/alpine:3.4

The push refers to a repository [docker.io/firewarm/alpine]
