简单记录：
1.拉原始镜像
docker pull regsitry
docker pull centos
2.启动registry仓库
docker run -t -i -d -p 5000:5000 -v /root/my_registry:/tmp/registry registry [你懂的]
3.给进行打标签
docker tag 9dbcac75201e docker10.sklinux.com:5000/centos:7 [tag为仓库地址+端口+名称+版本]
4.推送镜像至私有仓库
docker push docker10.sklinux.com:5000/centos:7[你懂的]
