Dockerでのrails環境構築について

Question

こちらの記事を参考にして、　Dockerでrailsの環境構築を行いました。
https://qiita.com/azul915/items/5b7063cbc80192343fc0

先週行った時は、エラーも出ず無事成功しましたが
今回改めて行ったところ、

   No connection pool with 'primary' found.

というエラーに遭遇しました。

ターミナル上では、エラーになる瞬間に以下文章が追加されます。

先週からDockerを学び始めましたが、よくわかっておりません。
もしよろしければ、アドバイスいただければ恐縮です。

Answer 1

もう一度作り直したら解決しました。おそらくgemのversionの問題ですが、再度rails環境構築を行った際は
database.ymlのところでエラーが出たので、developmentを追加したところ無事解決しました！
