如何搭建私有Registry

# docker run -d -p 5000:5000 -v /registry:/tmp/registry --name=docker_registry registry
[root@localhost ~]# docker run -d -p 5000:5000 -v /opt/data/registry:/tmp/registry docker.io/registry
如何启动：
[root@localhost ~]# docker run -d -p 5000:5000 registry
进入registry：
[root@localhost ~]# docker exec -it a19b39b5cd25  bash
访问仓库：
[root@localhost ~]# curl 127.0.0.1:5000
打标签centos--centos-server
[root@localhost ~]# docker tag centos 127.0.0.1:5000/centos-server
上传至registry
[root@localhost ~]# docker push 127.0.0.1:5000/centos-server
The push refers to a repository [127.0.0.1:5000/centos-server] (len: 1)
