echo ========================================
echo 部署步骤:
echo ========================================
echo.
echo 1. 将镜像文件传输到目标服务器
echo.
echo 2. 加载Docker镜像:
echo    docker load -i %SERV_IMAGE_FILE%
echo    docker load -i %WEB_IMAGE_FILE%
echo.
echo 3. 验证镜像:
echo    docker images ^| findstr school-news
echo.
echo 4. 启动服务:
echo    cd docker\schoolNews
echo    docker-compose up -d
echo.
echo 5. 查看服务状态:
echo    docker-compose ps
echo    docker-compose logs -f

echo ========================================
echo 注意事项:
echo ========================================
echo 1. 确保目标服务器已安装Docker和Docker Compose
echo 2. 确保端口8080、8081、3306、6379未被占用
echo 3. 首次部署需要准备数据库初始化脚本
echo 4. 生产环境请修改默认密码（.env文件）
