＞ローカルディレクトリにappフォルダが生成されません。
フォルダ名「app」をどこで指定しているのですか？
公式ドキュメント通りに作っていったのですが、
docker-compose run web rails new . --force --no-deps --database=postgresqlを入力しても
ローカルディレクトリにappフォルダが生成されません。
docker-compose run web lsでコンテナ内にあるのか調べたのですが、生成されていませんでした。
考えられる原因はなんでしょうか？

フォルダの名前を「myapp」以外にすると、このようなログが出力されます。
myappの部分をすべて任意の名前のフォルダ名に変更したのですが、なぜこのような現象が起きるのでしょうか。

参照している公式ドキュメントのすぐ下に書いてあるように、
フォルダは生成されません
ファイルは docker-compose.yml などと同階層に作成されます

どこかで書き換えを誤っているものと思われます
