Docker registry 搭建私有仓库

一、实验环境

准备两台装有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 上传镜像到私有仓库 虚拟机02用作 拉取镜像

二、搭建私有仓库 1、虚拟机01下载registry

[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.

[root@localhost ~]# 

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

要注意要在同一{}内，不要忘记加,号

[root@localhost ~]# vi /etc/docker/daemon.json
{
  "insecure-registries":["192.168.111.131:5000"],   //注意把我的ip换成你自己的
  "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、上传至私有仓库

[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 ~]# 

查看仓库镜像 ， 上传成功

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

三、虚拟机02 拉取私有仓库镜像 1、同样修改daemon配置文件 /etc/docker/daemon.json (没有的自动创建)

[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

3、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"]
}
