服务端（私有仓库：centos7_64位），使用端：centos6_64位
1、仓库的搭建：
安装docker：
yum -y install epel-release yum -y install docker-io
systemctl start docker
将本地的仓库换成阿里云的镜像仓库：
vim /etc/docker/daemon.json # 内容如下： { "registry-mirrors": ["https://cvv5tle1.mirror.aliyuncs.com"] # 这里的镜像源是我专属的, 其他人用可能起不到加速效果 } systemctl daemon-reload systemctl restart docker 在本地注册阿里云的镜像: docker login --username=woccb registry.cn-hangzhou.aliyuncs.com/woccb2/chen 输入设置的密码
运行一个生成本地仓库的脚本：
sh registry-install.sh
[root@localhost ~]# cat registry-install.sh #!/bin/bash # Description: create a private registry v2.2 # Version: 0.2 # Author: headsen chen
set -o xtrace if [[ $UID -ne 0 ]]; then echo "Not root user. Please run as root." exit 0 fi # Install Docker if not docker -v if [[ $? -ne 0 ]]; then echo "Please install Docker first." exit 0 fi REGISTRY_VERSION=2.2 # Download registry image v2.2 docker pull registry:${REGISTRY_VERSION}
# Start registry container mkdir /opt/registry docker run -d -p 5000:5000 --restart=always -v /opt/registry:/var/lib/registry --name hummer_registry registry:${REGISTRY_VERSION}
检测生成的docker仓库：
[root@localhost ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES eaa972942548 registry:2.2 "/bin/registry /et..." 35 minutes ago Up 35 minutes 0.0.0.0:5000->5000/tcp hummer_registry [root@localhost ~]#
查询开放的端口：
[root@localhost ~]# lsof -i:5000 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME docker-pr 18119 root 4u IPv6 50113 0t0 TCP *:commplex-main (LISTEN)
2、客户端配置：
安装
yum -y install epel-release yum -y install device-mapper-event-libs yum -y install docker-io
修改配置文件（不修改无法和本地仓库进行认证连接）
vim /etc/sysconfig/docker # 加上黄色标注的部分就可以了
[root@localhost ~]# cat /etc/sysconfig/docker # /etc/sysconfig/docker # # Other arguments to pass to the docker daemon process # These will be parsed by the sysv initscript and appended # to the arguments list passed to docker -d other_args="--insecure-registry 192.168.159.131:5000" DOCKER_CERT_PATH=/etc/docker # Resolves: rhbz#1176302 (docker issue #407) DOCKER_NOWARN_KERNEL_VERSION=1
service docker restart
测试：下载一个镜像并上传到本地仓库
docker pull webdevops/nginx docker images docker tag webdevops/nginx 192.168.159.131:5000/nginx-chen # 注意这个固定的格式，否则报错 docker push 192.168.159.131:5000/nginx-chen #出现以下提示表示push成功，
# 如果是加上tag： docker push 192.168.159.131:5000/chen:latest
[root@localhost ~]# docker push 192.168.159.131:5000/nginx-chen The push refers to a repository [192.168.159.131:5000/nginx-chen] (len: 1) ca89ae17bc84: Image already exists 2eed794b7b9a: Image successfully pushed 15a4031b10d3: Image successfully pushed 15a4031b10d3: Buffering to Disk 6c4863f14961: Image already exists aa02f81f314b: Image already exists 0893fa3a44c9: Image successfully pushed 6565352c3a2b: Image successfully pushed 6565352c3a2b: Buffering to Disk e86584bf870d: Image successfully pushed 928d4898ab17: Image successfully pushed 928d4898ab17: Buffering to Disk 073806b60691: Image already exists 7eb5c12881e1: Image already exists 63474e4f2842: Image successfully pushed f7fdafe228d3: Image successfully pushed 8475d7efa2f0: Image successfully pushed 565220263a7c: Image successfully pushed 7d614f18edc3: Image successfully pushed Digest: sha256:417cfafb30d330f5de3c9cef12ee935a321d16593bdd903de3d1017ad3eaa3f3 [root@localhost ~]#
删除下载的镜像，并从本地的仓库进行下载，看速度是否提高：
docker rmi webdevops/nginx docker rmi 192.168.159.131:5000/nginx-chen
docker images
docker pull 192.168.159.131:5000/nginx-chen # 此时从本地的仓库进行下载，发现是极速的秒传
查询私有仓库中有哪些镜像：
[root@localhost ~]# curl -XGET http://192.168.159.131:5000/v2/_catalog {"repositories":["busybox"]} [root@localhost ~]# curl -XGET http://192.168.159.131:5000/v2/busybox/tags/list {"name":"busybox","tags":["latest"]}
