# 使用多阶段构建
# 阶段 1：构建前端
FROM node:16 AS frontend-build
WORKDIR /app/frontend
COPY frontend/package*.json ./
RUN npm install
COPY frontend/ .
RUN npm run build

# 阶段 2：运行后端 + 提供前端静态资源
FROM python:3.9-slim
WORKDIR /app

# 后端依赖
COPY backend/requirements.txt ./backend/requirements.txt
RUN pip install --no-cache-dir -r backend/requirements.txt

# 拷贝后端代码
COPY backend/ ./backend/

# 拷贝前端打包好的静态资源
COPY --from=frontend-build /app/frontend/dist ./frontend_dist

# 启动命令：运行后端，同时提供静态文件
CMD ["gunicorn", "-b", "0.0.0.0:7860", "backend.app:app"]
