1. Docker Compose 설치

여러 컨테이너를 하나의 서비스로 정의하고 관리

# 버전 확인
docker compose version

# 설치 (없는 경우)
sudo apt install docker-compose-plugin

# 수동 업데이트
DOCKER_CONFIG=${DOCKER_CONFIG:-$HOME/.docker}
mkdir -p $DOCKER_CONFIG/cli-plugins
curl -SL https://github.com/docker/compose/releases/download/v2.40.3/docker-compose-linux-x86_64 \
  -o $DOCKER_CONFIG/cli-plugins/docker-compose
chmod +x $DOCKER_CONFIG/cli-plugins/docker-compose

2. WordPress + MySQL 구성

docker-compose.yml

services:
  mysql:
    image: mysql:8
    volumes:
      - db:/var/lib/mysql
    environment:
      MYSQL_DATABASE: mydb
      MYSQL_USER: user
      MYSQL_PASSWORD: password
    networks:
      - mynet-bridge-2

  wordpress:
    image: wordpress:latest
    ports:
      - "8585:80"
    environment:
      WORDPRESS_DB_HOST: mysql:3306
      WORDPRESS_DB_USER: user
      WORDPRESS_DB_NAME: mydb
      WORDPRESS_DB_PASSWORD: password
    depends_on:
      - mysql
    networks:
      - mynet-bridge-2

  web:
    image: nginx:1.29.3-alpine
    ports:
      - "8383:80"

networks:
  mynet-bridge-2:
    external: true

volumes:
  db:

서비스 구성

서비스	이미지	포트	역할
mysql	mysql:8	3306	데이터베이스
wordpress	wordpress:latest	8585:80	CMS
web	nginx:1.29.3-alpine	8383:80	웹서버

---

3. 실행 및 관리

# 네트워크 먼저 생성
docker network create mynet-bridge-2

# 실행
docker compose up -d

# 상태 확인
docker compose ps

# 로그 확인
docker compose logs -f

# 중지
docker compose down

# 볼륨까지 삭제
docker compose down -v
