이 파일이 **자주 바뀌지 않기 때문에**, 도커는 파일을 탐지하여 이 단계의 **캐시**를 사용하여 다음 단계에서도 캐시를 사용할 수 있도록 합니다.

4. 요구 조건 파일에 있는 패키지 종속성을 설치합니다.

    `--no-cache-dir` 옵션은 `pip`에게 다운로드한 패키지들을 로컬 환경에 저장하지 않도록 전달합니다. 이는 마치 같은 패키지를 설치하기 위해 오직 `pip`만 다시 실행하면 될 것 같지만, 컨테이너로 작업하는 경우 그렇지는 않습니다.

    /// note | 노트

    `--no-cache-dir` 는 오직 `pip`와 관련되어 있으며, 도커나 컨테이너와는 무관합니다.

    ///

    `--upgrade` 옵션은 `pip`에게 설치된 패키지들을 업데이트하도록 합니다.
