1、发布到DockerHub上

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.在服务器上提交自己的镜像

[root@wq test]# docker login --help

Login Succeeded

4.登录完毕后就可以提交镜像了，docker push

[root@wq test]# docker images
REPOSITORY   TAG       IMAGE ID       CREATED        SIZE
diytomcat    latest    dfa3156617fc   40 hours ago   893MB

#出现问题如下
#直接push出现拒绝
[root@wq test]# docker push diytomcat
