docker-compose快速搭建docker私有仓库

1. 创建docker-compose.yml并填入如下内容

   version: '3'
   services:
    registry:
     restart: always
     image: registry:2
     ports:
       - 5000:5000
     environment:
       REGISTRY_HTTP_TLS_CERTIFICATE: /certs/registry.crt
       REGISTRY_HTTP_TLS_KEY: /certs/registry.key
       REGISTRY_AUTH: htpasswd
       REGISTRY_AUTH_HTPASSWD_PATH: /auth/htpasswd
       REGISTRY_AUTH_HTPASSWD_REALM: Registry Realm
     volumes:
       - /home/docker/registry:/var/lib/registry
       - /home/registry/cert:/certs
       - /home/registry/auth:/auth
    registry-ui:
      image: konradkleine/docker-registry-frontend:v2
      restart: always
      environment:
        - ENV_DOCKER_REGISTRY_HOST=registry
        - ENV_DOCKER_REGISTRY_PORT=5000
        - ENV_DOCKER_REGISTRY_USE_SSL=1
      ports:
        - "5001:80"
   

   其中REGISTRY_HTTP_TLS_CERTIFICATE为ssl证书，此证书可以自己生成也可以去阿里云等网站申请，由于是私有仓库，笔者建议采用私有证书

2. 复制此文件，并执行docker-compose up命令

3. 创建登录用户和密码

   docker run --entrypoint htpasswd registry:2 -Bbn username password >> /home/registry/auth/htpasswd
   

4. 打开浏览器，输入http://本机ip:5001看到如下页面即代表访问成功

5. 点击btowse repositories会弹出用户名密码输入框，输入上面创建的用户名密码即可查看仓库中所有的镜像
