docker容器内配置apt-get软件源镜像源

查看：

cat /etc/apt/sources.list

执行tee(用于显示程序的输出并将其复制到一个文件中)（或者用vim把以下除了EOF之外的代码粘贴进去，貌似粘贴不了内容奇怪）:

tee /etc/apt/sources.list << EOF
deb http://mirrors.aliyun.com/debian/ stretch main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ stretch main non-free contrib
deb http://mirrors.aliyun.com/debian-security stretch/updates main
deb-src http://mirrors.aliyun.com/debian-security stretch/updates main
deb http://mirrors.aliyun.com/debian/ stretch-updates main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ stretch-updates main non-free contrib
deb http://mirrors.aliyun.com/debian/ stretch-backports main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ stretch-backports main non-free contrib
EOF

更新：

apt-get update
