私たち人間は常に**間違い**を犯します。ソフトウェアには、ほとんど常に**バグ**があらゆる箇所に隠されています。🐛

### 小さなエラーは自動的に処理される

FastAPIでWeb APIを構築する際に、コードにエラーがある場合、FastAPIは通常、エラーを引き起こした単一のリクエストにエラーを含めます。🛡

クライアントはそのリクエストに対して**500 Internal Server Error**を受け取りますが、アプリケーションは完全にクラッシュするのではなく、次のリクエストのために動作を続けます。

### 重大なエラー - クラッシュ

しかしながら、**アプリケーション全体をクラッシュさせるようなコードを書いて**UvicornとPythonをクラッシュさせるようなケースもあるかもしれません。💥

## Gunicorn과 함께하는 공식 도커 이미지 - Uvicorn

앞 챕터에서 자세하게 설명된 것 처럼, Uvicorn 워커와 같이 실행되는 Gunicorn을 포함하는 공식 도커 이미지가 있습니다: [서버 워커 - Uvicorn과 함께하는 Gunicorn](server-workers.md){.internal-link target=_blank}.

이 이미지는 주로 위에서 설명된 상황에서 유용할 것입니다: [다중 프로세스를 가지는 컨테이너와 특수한 경우들](#containers-with-multiple-processes-and-special-cases).
