수강환경 VirtualBox -> Docker

어디에 올리는 것이 적합한지 모르겠어서 여기에 올려봅니다.

혹시 virtual box 사용하여 강의 환경설정하시는 것이 조금 번거로우신 분들을 위해, 강의 실습을 진행하며 사용했던 docker-compose 파일을 공유드립니다!

강의의 세부적인 부분까지 따라하진 못할수도 있지만, 좀 더 편하고 빠르게 수업을 따라가실 수 있으실거에요. 너무나 좋은 강의 감사드립니다!

(사용하시게 되면 connector config 파일들에서 DB connection url localhost 부분을 mysql로 바꿔서 등록하시면 되요)
