# 实验室预约与资源管理平台 - 一键部署编排
#
# 启动：docker compose up -d --build
# 访问：前端 http://localhost:${WEB_PORT:-80}
#       后端 http://localhost:${BACKEND_PORT:-8080}
# 停止：docker compose down          （保留数据库数据卷）
#        docker compose down -v       （同时删除数据库数据，首次初始化会重建演示数据）
#
# 可通过环境变量覆盖：DB_NAME / DB_USER / DB_PASSWORD / DB_ROOT_PASSWORD /
#                    LAB_JWT_SECRET / WEB_PORT / BACKEND_PORT
