下载和安装gitlab

1. 去docker hub下载指定版本的itlab ce镜像

2. 创建GITLAB_HOME的环境变量.

   sudo vim .bashrc
   export GITLAB_HOME=/srv/gitlab
   source .bashrc
   
   root@DESKTOP-1T50PP8:~# cat .bashrc| grep GITLAB
   export GITLAB_HOME=/srv/gitlab
   
   root@DESKTOP-1T50PP8:~# echo $GITLAB_HOME
   /srv/gitlab
   

3. 照着gitlab官网准备一个docker-compose.yml

   version: '1.0'
   services:
     web:
   	image: 'gitlab/gitlab-ce:12.0.2-ce.0'
   	restart: always
      # hostname: 'gitlab.example.com'
      # environment:
      #   GITLAB_OMNIBUS_CONFIG: |
   	   # external_url 'https://gitlab.example.com'
   		# Add any other gitlab.rb configuration here, each on its own line
   	ports:
   	  - '80:80'
   	  - '443:443'
   	  - '22:22'
   	volumes:
   	  - '$GITLAB_HOME/config:/etc/gitlab'
   	  - '$GITLAB_HOME/logs:/var/log/gitlab'
   	  - '$GITLAB_HOME/data:/var/opt/gitlab'
   	shm_size: '256m'
   

4. 在docker-compose.yml目录执行 docker compose up -d启动gitlab

restore gitlab

1. 进入gitlab容器，查看备份文件需在的位置

   docker exec -it gitlab-web-1 /bin/sh
   # cat /etc/gitlab/gitlab.rb | grep backup_path
   # gitlab_rails['manage_backup_path'] = true
   # gitlab_rails['backup_path'] = "/var/opt/gitlab/backups"
   # exit
   

2. 把备份文件拷贝到 $GITLAB_HOME/data/backup后，执行 docker exec -it gitlab-web-1 gitlab-rake gitlab:backup:restore BACKUP=1619799951_2021_04_30_12.0.2,由于gitlab版本太低只能用这个命令。
