一.登录Docker Hub

1>.访问Docker Hub官网(https://hub.docker.com/)

2>.点击“Create Repository”(自行注册一下docker hub官网的id，大约不到2分钟就能搞定）

3>.填写创建仓库的相关信息后，并点击"Create"

4>.镜像仓库创建成功

 

二.上传镜像到Docker Hub

1>.在命令中中登录Docker Hub

[root@docker101.yinzhengjie.org.cn ~]# docker login -u yinzhengjie2019
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@docker101.yinzhengjie.org.cn ~]# 

　　如下图所示，登录成功可以看到docker的镜像仓库地址。

2>.对本地镜像打tag编号

[root@docker101.yinzhengjie.org.cn ~]# docker image ls

 3>.将镜像推送到Docker Hub的Registry

[root@docker101.yinzhengjie.org.cn ~]# docker image ls
