1.创建私有docker registry：
docker run -d -p 5000:5000 -v /opt/data/registry:/tmp/registry --name registry registry:2
清理过期容器的shell脚本：
#!/bin/bash
docker stop $(docker ps -a -q)
docker rm $(docker ps -a -q)
2.创建docker registry，假如不使用默认的https格式，那么所有的客户端和服务端必须设置--insecure-registry的标志，才可以成功的使用push和pull命令。
注意：windows docker machine目前没有解决方案，可谷歌解决方案，在创建virtual machine时候传入-insecure-registry参数。
linux系统下具体错误信息：
[[email protected] ~]# docker pull 42.62.101.83:5000/busybox
Using default tag: latest
Error response from daemon: Get https://42.62.101.83:5000/v1/_ping: tls: oversized record received with length 20527
下面为Centos的设置步骤：
备份原有的服务：cp /usr/lib/systemd/system/docker.service /usr/lib/systemd/system/docker.service.bak
更改服务内容配置： vi /usr/lib/systemd/system/docker.service
