compose.yml 파일에 서비스 별로 띄울 컨테이너들을 작성한다.
다수의 컨테이너를 관리하기 용이하다.
1. Docker Compose 로 MySQL, Redis 실행
1) compose.yml 파일 작성
- compose-practice/compose.yml
services:
my-db:
image: mysql
environment:
MYSQL_ROOT_PASSWORD: pwd123
volumes:
- ./mysql_data:/var/lib/mysql
ports:
- 3306:3306
my-cache-server:
image: redis
ports:
- 6379:6379
* 주의
YAML 문법에서 들여쓰기 중요!
2) compose 파일 실행
- Windows PowerShell
PS C:\Users\admin\compose-practice> docker compose up -d
[+] up 3/3
✔ Network compose-practice_default Created 0.0s
✔ Container compose-practice-my-cache-server-1 Started 0.6s
✔ Container compose-practice-my-db-1 Started 0.6s
What's next:
Filter, search, and stream logs from all your Compose services
in one place with Docker Desktop's Logs view. docker-desktop://dashboard/logs?appId=compose-practice
3) compose 실행 현황 확인
- Windows PowerShell
PS C:\Users\admin\compose-practice> docker compose ps

compose-practice-my-cache-server-1 redis "docker-entrypoint.s…" my-cache-server 43 seconds ago Up 41 seconds 0.0.0.0:6379->6379/tcp, [::]:6379->6379/tcp

4) 컨테이너 로그 확인
- Windows PowerShell
