既存のrails6アプリでdocker環境上にyarn

前提・実現したいこと

既存のRails6アプリケーションでdockerを使った環境構築をする際にyarnをインストールしたい。

発生している問題・エラーメッセージ

docker compose up 実行時にyarnがインストールされていないためrails sが実行できないと言われるのでDockerfileにyarnインストールのためのあらゆる記述をしてdocker compose buildを試したのですが~~not foundなどのエラーが出てしまい、実行できません。

エラーメッセージ

/bin/sh: 1: sudo: not found

/bin/sh: 1: brew: not found

Yarn was installed, but doesn't seem to be working :(.
