k8s 배포 정의에 데이터베이스 계정 관련 환경변수가 잘못 설정되어 있는 문제

버그

(선택) 에픽

(필수) 요약

현재 배포된 k8s 리소스에 환경변수 키값이 정확히 매칭되지 않아서 애플리케이션에서 DB 커넥션이 붙지 않음
(필수) 재현 단계

배포하자마자 로그 보면 확인 가능
(필수) 예상되는 올바른 동작

하이버네이트에서 정상적으로 연결이 되어야 함
환경변수 키 값이 DATABASE_USER -> DATABASE_MYSQL_USER 로 변경되어야 함 (패스워드도 마찬가지)
(필수) 버그로 추측되는 현재 동작

하이버네이트에서 DB 연결이 안 됨
