使用DockerHub管理Docker镜像

访问https://hub.docker.com/申请一个自己的账号

注册后选择免费的社区版即可

经过邮箱验证后，即可创建自己的镜像库了

 这里我们选择创建一个私有镜像库

在创建镜像库时，我们可以选择关联GitHub，并设置自定义构建规则：此时每当我们向GitHub中gittesting库的master分支push代码后，都会自动构建docker镜像并将该镜像上传至DockerHub

这样DockerHub上的镜像库就创建好了 

 

然后我在GitHub中gittesting库的master分支下新增了一个DockerFile文件，文件内容为

from java

提交后果然触发了DockerHub的自动构建

可以发现私有库已经成功启动了，上传一个镜像尝试一下

需要注意的是，默认会push到DockerHub，所以一定要用Docker Tag命令重新打Tag将push地址修改为localhost:5000

$ docker tag seanzou6688/sean_images:1.0 localhost:5000/seanzou6688/sean_images:1.0

$ docker images
