# 设置工作目录
WORKDIR /app

# 复制requirements并安装Python依赖
COPY requirements_fastapi.txt .
RUN pip install --upgrade pip setuptools wheel && \
    pip install --no-cache-dir --user -r requirements_fastapi.txt

# 第二阶段：运行时镜像
FROM python:3.9-alpine

# 安装运行时依赖
RUN apk update && \
    apk add --no-cache \
        curl \
        bash && \
    rm -rf /var/cache/apk/*

# 从构建阶段复制Python包
COPY --from=builder /root/.local /root/.local

# 设置工作目录
WORKDIR /app

# 复制应用代码

# 创建必要目录
RUN mkdir -p /app/logs /app/test_reports /app/uploads

# 设置环境变量
ENV PATH=/root/.local/bin:$PATH
ENV PYTHONPATH=/app
ENV PYTHONUNBUFFERED=1

# 暴露端口
EXPOSE 5050

# 健康检查
