Docker registry 搭建私有仓库

一、实验环境

准备两台装备docker的虚拟机

虚拟机01：192.168.111.131

虚拟机02：192.168.111.128

虚拟机01用作 将镜像上传到私人仓库 虚拟机02用作 拉取镜像

二、搭建私有仓库

下载虚拟机01registry

[root@localhost ~]# docker pull registry Using default tag: latest latest: Pulling from library/registry 79e9f2f55bf5: Pull complete  0d96da54f60b: Pull complete  5b27040df4a2: Pull complete  e2ead8259a04: Pull complete  3790aef225b9: Pull complete  Digest: sha256:169211e20e2f2d5d115674681eb79d21a217b296b43374b8e39f97fcf866b375 Status: Downloaded newer image for registry:latest docker.io/library/registry:latest [root@localhost ~]# 

2.创建仓库容器并运行

[root@localhost ~]# docker run -d -v /home/registory:/var/lib/registry -p 5000:5000 --restart=always --privileged=true --name registry registry:latest WARNING: IPv4 forwarding is disabled. Networking will not work. 1e9a65b8d6cbdeb12f0dccb0133d83ebf298bc9173f002c21bf0cb76065167f3 [root@localhost ~]# 

3、修改daemon配置文件 /etc/docker/daemon.json (无自动创建)

注意同一{}，不要忘记加号码

[root@localhost ~]# vi /etc/docker/daemon.json {   "insecure-registries":["192.168.111.131:5000"],   //注意我的ip换成自己的   "registry-mirrors": ["https://r1lazpp7.mirror.aliyuncs.com"] }

4、重启服务

[root@localhost ~]# systemctl daemon-reload [root@localhost ~]# systemctl restart docker

5、给nginx 打上 tag 标签

[root@localhost ~]# docker tag nginx:latest 192.168.111.131:5000/nginx:latest

6.上传到私人仓库

[root@localhost ~]# docker push 192.168.111.131:5000/nginx Using default tag: latest The push refers to repository [192.168.111.131:5000/nginx] b6812e8d56d6: Pushed  7046505147d7: Pushed  c876aa251c80: Pushed  f5ab86d69014: Pushed  4b7fffa0f0a4: Pushed  9c1b6dd6c1e6: Pushed  latest: digest: sha256:61face6bf030edce7ef6d7dd66fe452298d6f5f7ce032afdd01683ef02b2b841 size: 1570 [root@localhost ~]# 

检查仓库镜像 ， 上传成功

[root@localhost ~]# curl http://192.168.111.131:5000/v2/_catalog {"repositories":["nginx"]} [root@localhost ~]#  

三、虚拟机02 拉私人仓库镜像

1、同样修改daemon配置文件 /etc/docker/daemon.json (无自动创建)

[root@localhost ~]# vim /etc/docker/daemon.json  {    "insecure-registries":["192.168.111.131:5000"] }

2.同样重启服务

[root@localhost ~]# systemctl daemon-reload [root@localhost ~]# systemctl restart docker

同样拉取镜像

[root@localhost ~]# docker pull 192.168.111.131:5000/nginx Using default tag: latest latest: Pulling from nginx 1fe172e4850f: Pull complete  35c195f487df: Pull complete  213b9b16f495: Pull complete  a8172d9e19b9: Pull complete  f5eee2cb2150: Pull complete  93e404ba8667: Pull complete  Digest: sha256:61face6bf030edce7ef6d7dd66fe452298d6f5f7ce032afdd01683ef02b2b841 Status: Downloaded newer image for 192.168.111.131:5000/nginx:latest 192.168.111.131:5000/nginx:latest [root@localhost ~]# 

查看是否有 192.168.111.131:5000/nginx

[root@localhost ~]# docker images REPOSITORY                   TAG       IMAGE ID       CREATED      SIZE 192.168.111.131:5000/nginx   latest    fa5269854a5e   9 days ago   142MB [root@localhost ~]# 

拉取成功

四、创建多个库

[root@localhost ~]# vim /etc/docker/daemon.json  {   "insecure-registries":["192.168.111.131:5000","ip地址:port2","ip地址:port3"],   "registry-mirrors": ["https://r1lazpp7.mirror.aliyuncs.com"] }
