# 使用多阶段构建来分离构建环境和运行环境

# 1. 先只复制依赖文件
COPY requirements.txt .

# 换源和安装构建依赖
RUN sed -i 's/deb.debian.org/mirrors.ustc.edu.cn/g' /etc/apt/sources.list.d/debian.sources \
    && sed -i 's|security.debian.org/debian-security|mirrors.ustc.edu.cn/debian-security|g' /etc/apt/sources.list.d/debian.sources

# 安装构建依赖
RUN apt-get update \
    && apt-get install -y --no-install-recommends gcc python3-dev \
    && rm -rf /var/lib/apt/lists/*

# 安装Python依赖
RUN pip install --upgrade pip -i https://mirrors.aliyun.com/pypi/simple \
    && pip install --user -r requirements.txt -i https://mirrors.aliyun.com/pypi/simple

# 第二阶段：运行环境
FROM python:3.10-slim

WORKDIR /app

# 换源
RUN sed -i 's/deb.debian.org/mirrors.ustc.edu.cn/g' /etc/apt/sources.list.d/debian.sources \

# 安装运行时的系统依赖（只安装必要的）
RUN apt-get update \

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

# 设置PATH让Python可以找到用户安装的包
ENV PATH=/root/.local/bin:$PATH
ENV PYTHONPATH=/app

# 设置时区
ENV TZ="Asia/Shanghai"

# 创建目录结构
RUN mkdir -p /var/log/app_server \
    && mkdir -p /var/log/supervisor \
    && mkdir -p /etc/supervisor/conf.d

# 复制配置文件
COPY deploy/supervisor.conf /etc/supervisor/supervisord.conf
COPY deploy/app_server.conf /etc/supervisor/conf.d/

# 最后复制应用代码（利用Docker缓存层）
COPY backend/ ./backend
