ec2 설정

이전과 마찬가지로 80 포트를 열어 줌. ec2(80) -> docker(80[nginx:80]) -> web(uwsgi[apps.sock]) -> django

scp -ri <aws_credential.pem> <project> ubuntu@<public ip>:/home/ubuntu/

ec2 접속후 실행

cd ~/<project>
docker-compose up -d --build # 빌드 & 런

# 소스를 수정 했다면
docker-compose down # 내림
docker-compose up -d # 데몬으로 다시 돌림
