[root@docker01 mysql]# docker tag workpress/nginx:1.0 192.168.159.159:5000/nginx:1.1
[root@docker01 mysql]# docker images

直接上传到仓库

docker push 192.168.159.159:5000/nginx:1.1

查看挂载目录是否有镜像

[root@docker01 mysql]# ls /registry/
docker

关于本地镜像的查看

[root@docker01 mysql]# curl  http://192.168.159.159:5000/v2/_catalog
{"repositories":["nginx"]}

有1个镜像，可以获取他的标签信息以便下载

[root@docker01 mysql]# curl  http://192.168.159.159:5000/v2/nginx/tags/list
{"name":"nginx","tags":["1.1"]}

直接下载镜像

docker pull 192.168.159.159:5000/nginx:1.1

192.168.159.159:5000是仓库地址
docker -rmi 只能删除本地的，不能删除仓库里面的
