dockerでwebサーバー立ち上げて、ポスグレのDBから取ってこれるようにしようとしていて

サーバー内にファイルを新規で作ろうとして

docker-compose exec -it web bash

root@ed6e1fe3bbf8:/var/www/html# vim index.php
bash: vim: command not found
root@ed6e1fe3bbf8:/var/www/html# apt-get install -y vim
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package vim

とこのエラーが出た

vim使えないの？？

ネットで調べると、まずｕｐｄａｔｅが必要だそうで

root@ed6e1fe3bbf8:/var/www/html# apt update

してみると
