# 1. 设置环境变量，指定浏览器安装和查找的路径
ENV PLAYWRIGHT_BROWSERS_PATH=/home/user/.cache/ms-playwright

# 2. 创建一个非 root 用户 'user' (UID 1000)，与 Hugging Face 运行时用户一致[reference:8]
RUN useradd -m -u 1000 user

# 3. 切换到 'user' 用户来安装浏览器，确保文件拥有正确的权限[reference:9]
USER user

# 4. 现在以 'user' 身份安装 Chromium 浏览器到指定路径[reference:10]
RUN python -m playwright install chromium && python -m playwright install-deps
