国内访问不了docker源，不会”科学上网“的同学可以把官方源改变成国内源

#更新apt-get源 使用163的源

RUN mv /etc/apt/sources.list /etc/apt/sources.list.bak && \
    echo "deb http://mirrors.163.com/debian/ stretch main non-free contrib" >/etc/apt/sources.list && \
    echo "deb http://mirrors.163.com/debian/ stretch-updates main non-free contrib" >>/etc/apt/sources.list && \
