클라우드 47일차 : mid project

Error: connect ECONNREFUSED 172.18.0.2:3306 app-1 at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1555:16)
docker compose up --build 중 오류
연결이 거부된 (ECONNREFUSED) 이유는 MySQL 서버가 아직 완전히 준비되지 않았기 때문
MySQL 서버가 시작되고 준비되는 동안 애플리케이션이 너무 일찍 연결을 시도

healthcheck를 넣어줘 server가 db(mysql)이 실행된 후에 실행하도록 설정

route가 적용되지 않아 에러 페이지가 뜨는 문제
