搭建docker私有库的具体方法

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)

#export TMPDIR="/mnt/bigdrive/docker-tmp"

2、下载

1

docker pull server1:5000/redis

3、提交推送
