1：进入某个docker容器中：
docker exec -it pgsql12 /bin/bash
2添加：
mv /etc/apt/sources.list /etc/apt/sources.list.bak
    echo "deb http://mirrors.163.com/debian/ jessie main non-free contrib" >> /etc/apt/sources.list
    echo "deb http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/sources.list
    echo "deb-src http://mirrors.163.com/debian/ jessie main non-free contrib" >>/etc/apt/sources.list
    echo "deb-src http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/sources.list

    可以每步分开操作
:/#  mv /etc/apt/sources.list /etc/apt/sources.list.bak
:/#  echo "deb http://mirrors.163.com/debian/ jessie main non-free contrib" >/etc/apt/sources.list
/#  echo "deb http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/sources.list
/#  echo "deb-src http://mirrors.163.com/debian/ jessie main non-free contrib" >>/etc/apt/sources.list
/#  echo "deb-src http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/sources.list
 
4.更新：
apt update
