도커 파일은 아래입니다.

FROM openjdk:17-jdk

COPY build/libs/*.jar /app.jar

ENTRYPOINT ["java","-jar","/app.jar"]

도커 컴포즈 파일 입니다.

services:
  my-server:
    build: .
    ports:
      - 8080:8080
    depends_on:
      my-db:
        condition: service_healthy
  my-db:
    image: mysql
    environment:
      MYSQL_ROOT_PASSWORD: 1234
      MYSQL_DATABASE: mydb
    volumes:
      - /Users/shchoi/Downloads/docker/mysql:/var/lib/mysql
    ports:
      - 3306:3306
    healthcheck:
      test: [ "CMD", "mysqladmin", "ping" ]
      interval: 5s
      retries: 10

yml파일 입니다.

spring:
  datasource:
    url: jdbc:mysql://my-db:3306/mydb
    username: root
    password: 1234
    driver-class-name: com.mysql.cj.jdbc.Driver

이렇게 하고 실행시 db는 up이 되는데 spring은 다운 됩니다. 로그는 좀 길긴한데 아래와 같습니다.

왜 안뜨는걸까요....;
