一、下载 registry 压缩包

wget https://github.com/distribution/distribution/releases/download/v2.8.1/registry_2.8.1_linux_amd64.tar.gz

二、解压 registry 压缩包，并复制到 /usr/bin/ 目录下

[root@qijing0 workspace_registry]# tar -zxvf registry_2.8.1_linux_amd64.tar.gz 
LICENSE
README.md
registry

mv registry /usr/bin/

三、创建配置文件

[root@qijing0 workspace_registry]# mkdir -p /etc/docker/registry

[root@qijing0 workspace_registry]# cat> /etc/docker/registry/config.yml <<EOF
version: 0.1
log:
  fields:
    service: registry
storage:
  cache:
    blobdescriptor: inmemory
  filesystem:
    rootdirectory: /var/lib/registry
http:
  addr: :5000
  headers:
    X-Content-Type-Options: [nosniff]
health:
  storagedriver:
    enabled: true
    interval: 10s
    threshold: 3
EOF

四、设置开机自启动

[root@qijing0 /]# cat > /usr/lib/systemd/system/registryd.service <<EOF
[Unit]
Description=private registry 
Documentation=https://github.com/distribution/distribution#readme

[Service]
ExecStart=/usr/bin/registry serve /etc/docker/registry/config.yml
User=root
Restart=on-failure
RestartSec=1500ms

[Install]
WantedBy=multi-user.target
EOF

• 写入 /usr/lib/systemd/system/registryd.service 文件

[root@qijing0 workspace_registry]# systemctl restart registryd && systemctl enable registryd

• 开机自动启动

[root@qijing0 workspace_registry]# systemctl status registryd

• 验证服务状态

五、安装用户界面

用户界面比较无所谓，自我感觉不用仔细配置（毕竟不关心界面的技术栈），二进制装还比较麻烦。直接使用docker 启动了：

[root@qijing0 ~]# docker run -d -p 5001:80 --env REGISTRY_TITLE='QIJING Private Docker Registry' --env REGISTRY_URL=http://192.168.3.1:5000 --env SINGLE_REGISTRY=true --name docker-registry-ui joxit/docker-registry-ui:latest          
bb8636f234642068b9e24ee4a92538f1639692d7739994b04ffe06768da7cbb0

浏览器访问ip地址，验证安装：

推送镜像，验证安装：

nerdctl push 192.168.3.1:5000/test-server:0.0.3 --insecure-registry

• 可以看到，现在已经推送成功了。

拉取镜像，验证安装：
