背景

我们可以像使用github一样使用阿里云远程镜像库，进行镜像的推送、拉取等操作

使用方法

把本地镜像推送到阿里云

1）、登录阿里云开发者平台 http://dev.aliyun.com，然后点击控制台，搜索容器镜像服务

2）、创建镜像仓库，输入命名空间(没有自动创建)、仓库名、摘要，点击下一步指定代码源为本地仓库即可

3）、然后按照弹出来的操作指南进行推送即可(命令前面不用加sudo)，以下为实例

$ docker images

$ docker tag 2ad0dab56fc5 registry.cn-beijing.aliyuncs.com/songzeceng/mycentos:1.2

$ docker push registry.cn-beijing.aliyuncs.com/songzeceng/mycentos:1.2
The push refers to repository [registry.cn-beijing.aliyuncs.com/songzeceng/mycentos]
fe6076440ddc: Pushed 
c5cfb0f8a420: Pushed

然后就可以在镜像搜索栏里搜索我们的镜像songzeceng.mycentos了

 也可以在我们的仓库里看到这个镜像

从阿里云上拉取镜像

从上面两种查找镜像的结果界面里，点击我们的镜像，都可以看到镜像的公网地址

 复制公网地址，然后docker pull即可

$ docker pull registry.cn-beijing.aliyuncs.com/songzeceng/mycentos:1.2
