发布自己的镜像

DockerHub

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

3、在我们服务器上提交自己的镜像

[root@dockertest tomcat]# 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

# 登录dockerhub
[root@localhost tomcat]# docker login -u 账号
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

4、登录完毕后就可以提交镜像了，就是一步 docker push

# push自己的镜像到服务器上！
[root@localhost tomcat]# docker push diytomcat
The push refers to repository [docker.io/library/diytomcat]

# push镜像的问题？
[root@localhost tomcat]# docker push xxxxxx/diytomcat:1.0
The posh refers to repository [docker.io/xxxxx/diytomcat2]
An image dose not exist locally with the tag: xxxxxx/diytomcat2

# 解决：增加一个tag docker tag 指定镜像的id dockerhub的用户名/镜像重命名:[tag]
[root@localhost tomcat]# docker tag bb64ab96b432 账号/tomcat:1.0

# docker push上去即可！自己发布的镜像，尽量带上版本号
[root@localhost tomcat]# docker push xxxxxx/tomcat:1.0
The push refers to repository [docker.io/library/tomcat]
