Summary of Changes

Hello @wlgns12370, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request modifies the Dockerfile to configure the garbage collection (GC) settings for the Java application. Specifically, it sets the maximum GC pause time to 100ms and includes other JVM arguments to optimize memory usage and GC behavior.

Highlights

• GC Max Pause Time: The GC max pause time is set to 100ms.
• JVM Arguments: JVM arguments such as -XX:+UseG1GC, -Xms2g, and -Xmx2g are added to the Dockerfile.

Code Review

이번 PR은 Dockerfile의 ENTRYPOINT에 JVM 옵션을 추가하여 GC 최대 일시 중지 시간을 100ms로 설정하고 힙 메모리를 2GB로 고정하는 변경 사항을 담고 있습니다. G1GC를 사용하고 최대 일시 중지 시간을 설정하는 것은 서비스 응답 시간을 개선하기 위한 좋은 시도입니다. 다만, 힙 크기를 하드코딩하는 대신 환경 변수로 설정하여 유연성을 높이는 방안과, Java 21에서 기본값인 G1GC 설정 옵션의 중복성에 대해 몇 가지 개선 의견을 제안합니다.

[gemini-code-assist]

힙 크기를 2g로 하드코딩하면 다른 메모리 사양을 가진 환경(예: 개발, 스테이징, 프로덕션)에서 애플리케이션을 실행할 때 유연성이 떨어집니다. 이미지를 재빌드하지 않고도 각 환경에 맞게 메모리 설정을 동적으로 변경할 수 있도록, Docker 컨테이너 실행 시점에 환경 변수를 통해 힙 크기를 주입하는 것을 권장합니다. 예를 들어, ENTRYPOINT를 쉘 스크립트로 감싸고, 스크립트 내에서 환경 변수를 읽어 JVM 옵션으로 전달하는 방식을 사용할 수 있습니다.
