1. Docker Compose 로 Spring Boot, MySQL 컨테이너 동시에 띄워보기
1) 프로젝트 셋팅
Spring initializr : https://start.spring.io/
Project: Gradle - Groovy
Language: Java
Spring Boot: 4.0.6
Project Metadata)
Group: com.example (보통 기업 도메인 들어감)
Artifact: compose-spring-boot-server (빌드 결과물, 프로젝트명)
Package name: com.example.compose-spring-boot-server
Packaging: Jar
Configuration: YAML
Java: 17
Dependencies(사용할 라이브러리): Spring Web(웹 프로젝트), Spring Boot DevTools, Spring Data JPA, MySQL Driver
Java 17 버전을 선택
2) 간단한 코드 작성
- src/main/java/com/example/compose_spring_boot_server/AppController.java
package com.example.compose_spring_boot_server;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class AppController {
@GetMapping("/")
public String home() {
return "Hello, World!";
}
}
3) application.yml 에 DB 연결 정보 작성
- src/main/resources/application.yaml
spring:
datasource:
url: jdbc:mysql://localhost:3306/mydb
username: root
password: pwd123
driver-class-name: com.mysql.cj.jdbc.Driver
4) 불필요한 테스트 코드 삭제
src/test/java/com/example/compose_spring_boot_server/ComposeSpringBootServerApplicationTests.java 경로 삭제
(테스트 완성시킬 수 있으면, 완성하여 진행)
5) Dockerfile 작성
- Dockerfile
# FROM openjdk:17-jdk
FROM eclipse-temurin:17-jdk
COPY build/libs/*SNAPSHOT.jar /app.jar
EXPOSE 8080
ENTRYPOINT ["java", "-jar", "/app.jar"]
컨테이너 절대 경로 사용
6) compose 파일 작성
스프링 부트 서버는 데이터베이스가 먼저 실행이 된 상태에서 실행되어야 한다.
- compose.yml
services:
my-server:
build: .
ports:
- 8080:8080
# my-db의 컨테이너가 생성되고 healthy 하다고 판단 될 때, 해당 컨테이너를 생성한다.
depends_on:
my-db:
condition: service_healthy
my-db:
image: mysql
environment:
MYSQL_ROOT_PASSWORD: pwd123
MYSQL_DATABASE: mydb # MySQL 최초 실행 시 mydb라는 데이터베이스를 생성해준다.
volumes:
- ./mysql_data:/var/lib/mysql
ports:
- 3306:3306
healthcheck:
test: ["CMD", "mysqladmin", "ping"] # MySQL이 healthy 한 지 판단할 수 있는 명령어
interval: 5s # 5초 간격으로 체크
retries: 10 # 10번까지 재시도
#1 depends_on: 서비스명: condition: service_healthy
서비스명 컨테이너가 생성되고 healthy 하다고 판단 될 때, 해당 컨테이너 생성
condition 종류)
service_healthy : 의존하는 서비스의 상태 검사(healthcheck)가 '정상(healthy)' 상태가 될 때까지 대기
(service_started 의존하는 서비스가 시작(start)되면 실행, service_completed_successfully 의존하는 서비스가 실행 완료하고 정상 종료(exit code 0) 될 때까지 대기(배치 작업, 데이터베이스 마이그레이션 컨테이너에 유용))
#2 healthcheck:
컨테이너 내부에서 서비스가 정상 작동중인지 주기적으로 확인
#3 test:
테스트 실행 명령어 (health 판단하는 명령어)
#4 interval:
검사 주기
#5 retries:
재시도 횟수
(timeout: 응답 대기 시간, start_period: 초기 부팅 대기 시간)
-> depends_on 의 condition 속성과 healthcheck 를 결합하면 의존하는 서비스가 단순히 '실행(running)' 되는 것을 넘어 '완벽하게 준비(healthy)' 된 상태가 될 때까지 다음 서비스의 시작을 지연시킬 수 있음
7) Spring Boot 프로젝트 빌드
- Windows PowerShell
PS C:\Users\admin\IdeaProjects\compose-spring-boot-server> ./gradlew clean build
Starting a Gradle Daemon, 2 incompatible and 2 stopped Daemons could not be reused, use --status for details
BUILD SUCCESSFUL in 8s
6 actionable tasks: 6 executed
Consider enabling configuration cache to speed up this build: https://docs.gradle.org/9.5.1/userguide/configuration_cache_enabling.html
8) compose 파일 실행

What's next:
View and search logs for all containers in one place
with Docker Desktop's Logs view. docker-desktop://dashboard/logs
Spring Boot 컨테이너 로그 확인시 에러 메시지가 떠있다.
에러 메시지 내용은 DB와 연결이 제대로 이루어지지 않았을 때 발생하는 내용이다.
에러 : Failed to initialize JPA EntityManagerFactory
11) DataGrip 에 연결
MySQL 이 정상 실행되는지 확인을 위해 DB GUI 툴(DataGrip)로 DB 연결을 시도하면, 정상적으로 연결이 된다.
데이터베이스 탐색기 우클릭 > 새로 작성 > 데이터 소스 > MySQL > MySQL
호스트: localhost
포트: 3306
사용자: root
비밀번호: pwd123
연결 테스트 성공 후, "적용" 버튼 클릭 후 "확인" 버튼 클릭
MySQL 은 정상 실행되는데, Spring Boot 가 MySQL 에 연결되지 않는 이유는 무엇일까?
