常规后台项目
# 基于镜像基础
FROM python:3.8
# 设置代码文件夹工作目录 /app
WORKDIR /app
# 复制当前代码文件到容器中 /app
ADD . /app
# 安装所需的包
RUN pip install -r requirements.txt
# Run app.py when the container launches
CMD ["python", "app.py"]

COPY o_domain.py .
COPY order_center.py .

RUN pip install --upgrade pip
RUN pip install flask

CMD ["python","ip_light.py"]
