本例在debian:buster-slim docker鏡像中實驗通過
1、啟動docker實例
docker run -it --name debian debian:buster-slim bash
2、進入容器備份原始軟件源配置文件
mv /etc/apt/sources.list /etc/apt/sources.list.bak
3、寫入網易軟件源地址或中科大軟件源地址到source.list文件
cat > /etc/apt/sources.list << EOF deb http://mirrors.163.com/debian/ buster main contrib non-free # deb-src http://mirrors.163.com/debian/ buster main contrib non-free deb http://mirrors.163.com/debian/ buster-updates main contrib non-free # deb-src http://mirrors.163.com/debian/ buster-updates main contrib non-free deb http://mirrors.163.com/debian/ buster-backports main contrib non-free # deb-src http://mirrors.163.com/debian/ buster-backports main contrib non-free deb http://mirrors.163.com/debian-security buster/updates main contrib non-free # deb-src http://mirrors.163.com/debian-security buster/updates main contrib non-free EOF
或
cat > /etc/apt/sources.list << EOF deb http://mirrors.ustc.edu.cn/debian/ buster main contrib non-free # deb-src http://mirrors.ustc.edu.cn/debian/ buster main contrib non-free deb http://mirrors.ustc.edu.cn/debian/ buster-updates main contrib non-free # deb-src http://mirrors.ustc.edu.cn/debian/ buster-updates main contrib non-free deb http://mirrors.ustc.edu.cn/debian/ buster-backports main contrib non-free # deb-src http://mirrors.ustc.edu.cn/debian/ buster-backports main contrib non-free deb http://mirrors.ustc.edu.cn/debian-security buster/updates main contrib non-free # deb-src http://mirrors.ustc.edu.cn/debian-security buster/updates main contrib non-free EOF
4、執行apt-get update命令更新軟件包索引
apt-get update
5、安裝vim、unzip等軟件包
apt-get install vim unzip
