 $ docker images
 > REPOSITORY               TAG       IMAGE ID       CREATED         SIZE
 > mysql                    latest    bdfb0ec4d54a   2 months ago    599MB

 $ docker tag mysql:latest 10.58.14.96:5000/mysql:latest
 $ docker images
 > REPOSITORY               TAG       IMAGE ID       CREATED         SIZE
 > mysql                    latest    bdfb0ec4d54a   2 months ago    599MB
 > 10.58.14.96:5000/mysql   latest    bdfb0ec4d54a   2 months ago    599MB

 $ docker push 10.58.14.96:5000/mysql:latest
 $ curl -XGET  http://10.58.14.96:5000/v2/_catalog
 > {"repositories":["mysql"]}

镜像管理​

管理私有仓库镜像

 $ curl -XGET  http://10.58.14.96:5000/v2/_catalog
 > {"repositories":["mysql"]}

 $ curl -XGET  http://10.58.14.96:5000/v2/mysql/tags/list
 > {"name":"mysql","tags":["latest"]}

删除私有仓库镜像, 官方删除方式只删除元数据, 镜像未删除
可以直接删除镜像文件方式删除仓库镜像

  # 直接进入映射路径删除镜像文件或进入容器路径删除镜像
  $ rm -rf {map_path}/docker/registry/v2/repositories/{image}
  $ docker exec registry rm -rf /var/lib/registry/docker/registry/v2/repositories/{images}

  $ rm -rf /var/lib/registry/docker/registry/v2/repositories/mysql

 $ curl -XGET  http://10.58.14.96:5000/v2/_catalog
 > {"repositories":[]}
