准备
server1，server2 （其中server1作为私有库服务器，server2作为普通客户端）
（相关推荐：docker教程）
在server1上
1、下载 registry
1
docker pull registry:latest
2、配置 /etc/default/docker 因为https需要证书密码等比较复杂，直接加 insecure-registry即可

# Docker Upstart and SysVinit configuration file
# Customize location of Docker binary (especially for development testing).
#DOCKER="/usr/local/bin/docker"
# Use DOCKER_OPTS to modify the daemon startup options.
#DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4"
DOCKER_OPTS="--insecure-registry 127.0.0.1:5000"
# If you need Docker to use an HTTP proxy, it can also be specified here.
#export http_proxy="http://127.0.0.1:3128/"
# This is also a handy place to tweak where Docker's temporary files go.
#export TMPDIR="/mnt/bigdrive/docker-tmp"
3、启动registry
1
sudo docker run --name registry -d -p 5000:5000 -v /home/docker_registry:/var/lib/registry --restart=always registry:latest
4、tag镜像
1
docker tag redis server1:5000/redis
5、推送保存私有镜像
1
docker push server1:5000/redis
5.1、查看推送到私有仓库的镜像

$ docker search 10.10.105.71:5000/tonybai/busyBox/
Error response from daemon: Unexpected status code 404
但通过v2版本的API，我们可以实现相同目的：
$curl http://10.10.105.71:5000/v2/_catalog
{"repositories":["tonybai/busyBox"]}
在server2（client）上
因为docker Registry中讲到， 如果采用insecure registry的模式，那么所有与Registry交互的主机上的Docker Daemon都要配置：–insecure-registry选项。除了这个模式还可以配置证书，在此不作说明
1、配置 -insecure-registry(centos:/etc/sysconfig/docker ubuntu:/etc/default/docker)
