1.使用Docker exec -it **** /bin/bash进入容器
2.使用echo -e 'nameserver 8.8.8.9' > /etc/resolv.conf 添加到/etc/resolv.conf文件
继续添加使用echo -e 'nameserver 6.6.6.6' >> /etc/resolv.conf
3.使用mv命令进行迁移，在使用echo命令添加到sources.list文件
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 && \
echo "deb http://mirrors.163.com/debian/ stretch-backports main non-free contrib" >>/etc/apt/sources.list && \
echo "deb-src http://mirrors.163.com/debian/ stretch main non-free contrib" >>/etc/apt/sources.list && \
echo "deb-src http://mirrors.163.com/debian/ stretch-updates main non-free contrib" >>/etc/apt/sources.list && \
echo "deb-src http://mirrors.163.com/debian/ stretch-backports main non-free contrib" >>/etc/apt/sources.list && \
echo "deb http://mirrors.163.com/debian-security/ stretch/updates main non-free contrib" >>/etc/apt/sources.list && \
echo "deb-src http://mirrors.163.com/debian-security/ stretch/updates main non-free contrib" >>/etc/apt/sources.list
如果要使用aliyun的镜像，改成如下方式：
deb http://mirrors.aliyun.com/debian wheezy main contrib non-free
deb-src http://mirrors.aliyun.com/debian wheezy main contrib non-free
deb http://mirrors.aliyun.com/debian wheezy-updates main contrib non-free
deb-src http://mirrors.aliyun.com/debian wheezy-updates main contrib non-free
deb http://mirrors.aliyun.com/debian-security wheezy/updates main contrib non-free
deb-src http://mirrors.aliyun.com/debian-security wheezy/updates main contrib non-free
