运行一个ubuntu容器
docker run -i -t ubuntu /bin/bash
备份apt源
cp /etc/apt/sources.list /etc/apt/sources.list.bak
修改apt源
vi /etc/apt/sources.list
替换所有源为sohu源
deb http://mirrors.sohu.com/ubuntu/ trusty main restricted universe multiverse deb http://mirrors.sohu.com/ubuntu/ trusty-security main restricted universe multiverse deb http://mirrors.sohu.com/ubuntu/ trusty-updates main restricted universe multiverse deb http://mirrors.sohu.com/ubuntu/ trusty-proposed main restricted universe multiverse deb http://mirrors.sohu.com/ubuntu/ trusty-backports main restricted universe multiverse deb-src http://mirrors.sohu.com/ubuntu/ trusty main restricted universe multiverse deb-src http://mirrors.sohu.com/ubuntu/ trusty-security main restricted universe multiverse deb-src http://mirrors.sohu.com/ubuntu/ trusty-updates main restricted universe multiverse deb-src http://mirrors.sohu.com/ubuntu/ trusty-proposed main restricted universe multiverse deb-src http://mirrors.sohu.com/ubuntu/ trusty-backports main restricted universe multiverse
或网易源

修改保存后退出运行的容器
exit
查看最后一个运行的容器
docker ps -l
提交本次修改的镜像为 ubuntu/sohu
docker commit 698 ubuntu/sohu
使用修改后源的镜像做Dockerfile
