One of those distributed container management systems like Kubernetes normally has some integrated way of handling...

내부적으로 `open("./somefile.txt")` 는 "컨텍스트 관리자(Context Manager)"라고 불리는 객체를 생성합니다.

`with` 블록이 끝나면, 예외가 발생했더라도 파일을 닫도록 보장합니다.

`yield`가 있는 의존성을 생성하면 **FastAPI**는 내부적으로 이를 위한 컨텍스트 매니저를 생성하고 다른 관련 도구들과 결합합니다.
