以debian/ubuntu为例，修改Dockerfile使用deiban和pip镜像。
RUN sed -i 's/deb.debian.org/mirrors.ustc.edu.cn/g' /etc/apt/sources.list
RUN sed -i 's|security.debian.org/debian-security|mirrors.ustc.edu.cn/debian-security|g' /etc/apt/sources.list
RUN pip config set global.index-url https://mirrors.aliyun.com/pypi/simple \
&& pip config set install.trusted-host mirrors.aliyun.com使用npm镜像
RUN npm config set registry https://registry.npm.taobao.org
