把项目打包成可部署的数据同步服务： - Dockerfile (multi-stage builder/runtime, slim base, 含 healthcheck) - docker-compose.yml (postgres:16-alpine + market_sync, 持久化 pgdata + logs) - .dockerignore (减 build context) - bin/service_run.sh (单进程跑 uvicorn + scheduler 线程) - app/entrypoints/worker.py 抽 start_scheduler_thread() (幂等) 部署: docker compose up -d # 然后访问 http://localhost:8100/docs 看 FastAPI 设计选择: - 单容器一服务（uvicorn 主 + scheduler daemon thread），不用 supervisord - 原 systemd timer 由进程内 scheduler 取代（配置已存在于 config 表） - PG 用 docker volume 持久化；同步日志单独 volume
