注意：提前安装docker和docker-compose）

1. 首先编辑docker-compose.yml文件，内容如下：

   version: '3'
   
   services:
     gitlab:
       image: gitlab/gitlab-ce:latest
       container_name: gitlab
       restart: always
       hostname: 'gitlab.mydomain.com'
       environment:
         TZ: 'Asia/Shanghai'
         GITLAB_OMNIBUS_CONFIG: |
           external_url 'https://gitlab.mydomain.com'
       ports:
         - '8880:8880'
         - '4443:443'
         - '222:22'
       volumes:
         - ./gitlab/config:/etc/gitlab
         - ./gitlab/data:/var/opt/gitlab
         - ./gitlab/logs:/var/log/gitlab
       logging:
         driver: 'json-file'
         options:
           max-size: '2g'
   
   

2. nginx配置

   sub_filter_once off; ### <--- 字符串进行多次替换
   sub_filter_types *; ### <--- 字符串替换生效的文件类型
   
   location / {
       proxy_set_header    X-Real-IP               $remote_addr;
       proxy_set_header    X-Forwarded-For         $proxy_add_x_forwarded_for;
       proxy_set_header    HTTP_X_FORWARDED_FOR    $remote_addr;
   
       proxy_pass https://127.0.0.1:4443; ### <--- 转发请求到 gitlab
   
       sub_filter '127.0.0.1:4443' 'gitlab.mydomain.com'; ### <--- 字符串替换
       sub_filter 'gitlab.mydomain.com:4443' 'gitlab.mydomain.com'; ### <--- 字符串替换
       sub_filter '[email protected]:' 'ssh://[email protected]:222/'; ### <--- 字符串替换
   }
   

3. 默认登录账号

   用户名: root (注意不是 admin 哈)
   密码需要使用下面命令来匹配（该密码文件会在重装后的24小时后删除），也可以进入 docker 查看

   docker exec -it gitlab grep 'Password:' /etc/gitlab/initial_root_password
