docker很多鏡像都用debian, 都是簡配, 連個vim也沒安裝.
所以需要自己配置debian源.
docker cp xxxx:/etc/apt/sources.list ./ vim sources.list ------------------------------ deb http://mirrors.xxxxx/debian stretch main deb http://mirrors.xxxxx/debian-security stretch/updates main deb http://mirrors.xxxxx/debian stretch-updates main ------------------------------ docker cp sources.list xxxx:/etc/apt/sources.list docker exec -it xxxx bash apt update apt install vim
