1. 컨테이너로 실행시킨 Spring Boot 가 MySQL 에 연결이 안 되는 이유
각각의 컨테이너는 자신만의 네트워크망과 IP 주소를 가진다. 호스트 컴퓨터 입장에서 localhost 는 호스트 컴퓨터를 가리키지만, Spring Boot 컨테이너 입장에서 localhost 는 Spring Boot 컨테이너를 가리킨다.
이 때 Spring Boot 컨테이너의 application.yml 에 설정된 localhost:3306 은 컨테이너 내부의 3306번 포트와 연결을 시도하게 된다. 하지만 3306번 포트엔 아무것도 실행되지 않았기 때문에, Spring Boot 가 MySQL 에 연결되지 않았던 것이다.
- src/main/resources/application.yaml
...
url: jdbc:mysql://localhost:3306/mydb
...
2. Spring Boot DB 정보 수정
한 컨테이너에서 다른 컨테이너와 통신하려면, compose.yml 파일에 정의한 service 이름으로 통신할 수 있다.
service 이름이 해당 컨테이너의 IP 주소와 같은 역할을 한다. 즉, 컨테이너 주소를 뜻한다.
- compose.yml
...
my-server:
...
my-db:
...
- src/main/resources/application.yaml
...
# url: jdbc:mysql://localhost:3306/mydb
url: jdbc:mysql://my-db:3306/mydb
...
코드 수정 후 Spring Boot 프로젝트 빌드한 뒤, 다시 컨테이너를 실행해본다.
