docker 查询或获取私有仓库(registry)中的镜像，使用

    docker search 192.168.1.8:5000

命令经测试不好使。

解决：

1、获取仓库类的镜像：

[root@shanghai docker]# curl -XGEThttp://192.168.1.8:5000/v2/_catalog

{"repositories":["nginx"]}

2、获取某个镜像的标签列表：

[root@shanghai docker]# curl -XGEThttp://192.168.1.8:5000/v2/image_name/tags/list

{"errors":[{"code":"NAME_UNKNOWN","message":"repositoryname not known toregistry","detail":{"name":"image_name"}}]}

[root@shanghai docker]# curl -XGEThttp://192.168.1.8:5000/v2/nginx/tags/list

{"name":"nginx","tags":["latest"]}

[root@shanghai docker]#
