[Rails]'docker-compose ps'で、すべてのコンテナが一覧に表示されない

Rails + Nginx + MySQL構成のアプリケーションをDockerを用いて構築しています。
docker-composeを使用してビルドと起動をしたのですが、docker-compose psで一部のコンテナしか一覧に表示されません。
ご助言をいただけると幸いです。

bash
1% docker ps

開発環境

macOS Monterey v12.1
ruby 3.0.1
Rails 6.1.4.4
docker 20.10.12
docker-compos 1.29.2

試したこと

コンテナとイメージの再作成（キャッシュ不使用およびボリュームの再作成含む）
curlで通信確認、ポート300に接続できない

bash
1% curl localhost:3000
2curl: (7) Failed to connect to localhost port 3000: Connection refused

MySQLのコンテナには入れる。またユーザーやパスワード、Host類の設定はdatabase.ymlでの指定と合っている

心当たり

一度gitのローカルリポジトリをめちゃくちゃにしてしまってリモートで上書きをした際に.envなどのファイルが消えてしまいました。その後のコンテナ再作成で不具合が発生していますので、このあたりに原因があると思って調査していました。

「docker ps」コマンドは稼動中のコンテナしか表示されません。
非活性を含むすべてのコンテナを表示させたい場合は「-a」オプションを付けてください。

docker ps -a

ありがとうございます。やはりアクティブなコンテナが、`docker-compose ps -a`では認識されていない様です。 ``` % docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 6fb3efccbbdd myapp_app_app "entrypoint.sh /bin/…" About an hour ago Up About an hour myapp_app_development 088f8230010d mysql:8.0.28 "docker-entrypoint.s…" About an hour ago Up About an hour 0.0.0.0:3306->3306/tcp, 33060/tcp myapp_db_development 79f5c9f9238f myapp_nginx "/docker-entrypoint.…" About an hour ago Up About an hour 0.0.0.0:80->80/tcp myapp_nginx_development % docker-compose ps -a Name Command State Ports ------------------------------------------------------------------------------------------ myapp_app_development entrypoint.sh /bin/sh -c b ...
