ENTRYPOINT를 한 줄로 수정한 것은 좋지만, 몇 가지 개선할 점이 보입니다.
egd속성: Java 21을 사용하시므로-Djava.security.egd=file:/dev/./urandom옵션은 더 이상 필요하지 않습니다. Java 9부터는/dev/urandom이 기본 엔트로피 소스로 사용됩니다.-Xms2g -Xmx2g와 같이 JVM 힙 크기가 하드코딩되어 있어 유연성이 떨어집니다.이 문제들을 해결하기 위해, 환경 변수를 사용하여 메모리 설정을 동적으로 주입하고
exec를 사용하는 것을 권장합니다. 아래 제안과 같이ENTRYPOINT를 변경하고, 이 줄 앞에ENV JAVA_OPTS="-Xms2g -Xmx2g"를 추가해주세요.exec를 사용하면 Java 프로세스가 컨테이너의 PID 1로 실행되어 Docker 시그널을 올바르게 처리할 수 있습니다.또한, 파일 끝에 개행 문자를 추가하는 것이 좋은 컨벤션입니다.
