[Docker] [실습3] Docker Compose 개념 및 실습

[실습] Docker compose 실행 및 중지, 삭제

도커 컨테이너는 단일 애플리케이션이다. 애플리케이션 배포 전용 컨테이너다.

⇒ 해결책 : Docker Compose ; ‘여러 컨테이너’ 실행 관리를 일괄적으로  yml(야물) 문서에 기술 설정. 

#1. detached 모드에서 yml 실행 # docker-compose.yml을 가져온다.
# 여러 개의 컨테이너로 이루어진 것을 compose로 묶는다.
docker-compose up -d

#2. 실행 중인 서비스 표시
docker-compose ps

#3. 실행 중인 서비스 중지
docker-compose stop

#4. 서비스 삭제
docker-compose down
