Docker registry cli 私有仓库镜像查询、删除、上传、下载 shell

 

#Docker官方私有仓库registry
#官方只提供了API接口,不方便使用,就写了个shell
#docker-registry安装配置http://www.cnblogs.com/elvi/p/8384604.html

#使用:
#复制代码保存为 img_registry.sh
 sh img_registry.sh  -h   #查看帮助

HUB=hub.test.com:5000 改为自己的地址

 

#shell代码 git地址https://gitee.com/almi/docker/blob/master/0.Shell/img_registry.sh
