1 登录阿里云

登录阿里云 >> 进入控制台 >> 搜索容器镜像服务

https://cr.console.aliyun.com/cn-hangzhou/instances

创建个人实例（上图已创建）>> 进入个人实例

创建命名空间

使用命名空间创建仓库（一个仓库对应一个docker镜像）>> 提交时选择本地仓库 >> 在镜像仓库列表点击管理操作（操作指南）

 

 

2 创建测试镜像

以redis:3.2拉取镜像，创建并启动容器，根据容器commit新的镜像myredis:1.0.0，对这个新镜像进行测试。

拉取镜像：

[root@localhost ~]# docker pull redis:3.2
3.2: Pulling from library/redis

运行容器：

[root@localhost ~]# docker images

3 推送测试镜像

根据根据第一步的操作指南，先登录阿里云，再对镜像myredis标记tag，再push；

登录阿里云

[root@localhost ~]# docker login --username=你的阿里云账号 registry.cn-hangzhou.aliyuncs.com
Password:
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
