[Docker] Docker compose로 Django, Nginx 띄우기 - 3 (docker-compose.yml, deploy.yml)

docker-compose.yml

#docker-compose.yml

services:
  backend: #컨테이너 이름
    build:
      context: ./djangobase2 # Dockerfile 위치
      dockerfile: Dockerfile
    image: mechauk418/backend:latest #이미지 이름
    ports:
      - "8000:8000"

    command: gunicorn config.wsgi:application --bind 0.0.0.0:8000
  
  nginx:
    build:
      context: ./nginx
      dockerfile: Dockerfile
    image: mechauk418/nginx:latest
    ports:
      - "80:80"
    depends_on:
      - backend

    command: [nginx-debug, '-g', 'daemon off;']

docker-compose.yml은 위와 같이 작성했다.

deploy.yml

github action 배포 설정에 대한 yml이다.

작업 순서는 다음과 같다.

1. 도커 허브 로그인
2. .env 파일 생성
3. docker-compose.yml 파일 복사 (SSH 접속)
4. 도커 실행 (SSH 접속)
