迁移docker部署的gitlab过程(经实战)

df -h  # 确认新硬盘挂载点
mkdir -p /mnt/new_disk/gitlab/{config,logs,data}

docker inspect gitlab | grep Mounts -A 20
# 或者如果是 docker-compose
docker-compose ps

# 如果是 docker-compose 部署
cd /path/to/your/gitlab-compose
docker-compose down

# 如果是 docker run 部署
docker stop gitlab
docker rm gitlab  # 迁移通常建议删除旧容器重新创建，数据在卷里不会丢

# 语法：rsync -av [源路径/] [目标路径/]
# 注意：源路径末尾加 / 表示复制目录内容，不加表示复制目录本身

sudo rsync -av /opt/gitlab/config/ /mnt/new_disk/gitlab/config/
sudo rsync -av /opt/gitlab/logs/ /mnt/new_disk/gitlab/logs/
sudo rsync -av /opt/gitlab/data/ /mnt/new_disk/gitlab/data/

version: '3'
services:
  web:
    image: 'gitlab/gitlab-ce:latest'
    # ... 其他配置 ...
    volumes:
      # 修改为新的硬盘路径
      - '/mnt/new_disk/gitlab/config:/etc/gitlab'
      - '/mnt/new_disk/gitlab/logs:/var/log/gitlab'
      - '/mnt/new_disk/gitlab/data:/var/opt/gitlab'

docker run -d \
    --hostname gitlab.example.com \
    -p 443:443 -p 80:80 -p 2222:22 \
    --name gitlab \
    --restart always \
    # 下面三行修改为新路径
    -v /mnt/new_disk/gitlab/config:/etc/gitlab \
    -v /mnt/new_disk/gitlab/logs:/var/log/gitlab \
    -v /mnt/new_disk/gitlab//var/opt/gitlab \
    gitlab/gitlab-ce:latest

# 将新目录的所有者递归修改为 998:998
sudo chown -R 998:998 /mnt/new_disk/gitlab/

# 确保目录权限正确
sudo chmod -R 755 /mnt/new_disk/gitlab/

# docker-compose
docker-compose up -d

# docker run
# (执行上面的 docker run 命令)

docker logs -f gitlab

# 备份旧数据以防万一
mv /opt/gitlab /opt/gitlab.bak

# 确认一切正常后再删除
# rm -rf /opt/gitlab.bak
