WORKDIR /app

# 先装依赖，利用缓存
COPY requirements.txt /app/requirements.txt
RUN pip install --no-cache-dir -r requirements.txt

# 安装 Chromium（缓存可复用）
RUN python -m playwright install chromium

# 拷贝应用代码
COPY app.py /app/app.py
# 如果你确实需要 postBuild 中的内容，直接删除下一行注释并确保仓库里有 postBuild 文件：
# COPY postBuild /app/postBuild
