feat(deps): Docker Compose 部署——PostgreSQL + Redis + Backend - #162
Merged
Conversation
- Add backend/Dockerfile with multi-stage build (uv + Python 3.12) - Add docker-compose.yml with backend and PostgreSQL services - Add db/init.sql for automatic database table initialization - Add .env.example with configuration template - PostgreSQL configured with port 7856 and secure password
…browser 三处让部署跑不起来的问题，都在这台服务器上实测定位： 1. 构建阶段 uv sync 超时。宿主机访问 pypi.org 需 8s，构建容器内默认超时会在 下载大包（uvloop）时 "operation timed out" 直接失败。改走国内镜像源并把 UV_HTTP_TIMEOUT 拉到 180s。 2. 容器起来即反复重启，报 "exec /app/.venv/bin/uvicorn: no such file or directory"。 文件其实存在，报的是它 shebang 指向的解释器——uv 装出来的 venv 里 shebang 与 .pth 都是绝对路径，builder 在 /build、runtime 在 /app，跨路径拷贝后解释器与 workspace 包全部失效。把 builder 的 WORKDIR 也改成 /app 即可。 3. 七牛上传 TLS 握手超时、媒体上传请求挂死。宿主机网卡 MTU 1480，而 compose 自建网络不继承 daemon 的 mtu 设置、默认仍是 1500，大包被丢。显式给网络设 1450 后，up-z0.qiniup.com 从握手超时 14s 变为 1.0s，上传恢复正常。 4. 浏览器跨域被全部拦下：OPTIONS 预检返回 405、响应无 access-control-* 头， 后端日志里连请求都看不到。挂上 CORSMiddleware，允许来源用 WINDUP_CORS_ORIGINS 覆盖，并放行 Vercel 预览域名。 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
后端验证码/refresh_token 依赖 Redis，原 compose 只有 Postgres。 新增 redis:7-alpine 服务（含健康检查），backend depends_on 等待就绪， 环境变量 REDIS_URL=redis://redis:6379/0。
ORM 声明了 UniqueConstraint(user_id, project_name)，但 init.sql 建表时遗漏。 生产 Postgres 并发创建同名项目不会触发 IntegrityError，API 兜底失效。 补上 CONSTRAINT uq_windup_project_user_name UNIQUE (user_id, project_name)。
