컨테이너 실행 네트워크 생성

root@albert:/work/study/gunicorn/nginx' docker network create mynetwork02

postgresql 설정

Dockerfile

FROM postgres:15.4

volume, 및 컨테이너 생성

root@albert:/work/study/gunicorn/postgres' docker volume create myvolume
        
root@albert:/work/study/gunicorn/django' docker container run --name postgrestest --network mynetwork02 -e POSTGRES_PASSWORD=mysecretpassword --mount type=volume,source=myvolume,target=/var/lib/postgresql/data -d npostgres

requirements.txt (django, gunicorn 버전추가)

django==4.2.7
gunicorn==20.1.0
psycopg2==2.9.9

Dockerfile(requirements.txt 기준으로 설치 및 8000포트로 접속가능하도록 gunicorn세팅)

FROM python:3.11.6

WORKDIR /usr/src/app

COPY . .

RUN python -m pip install --upgrade pip
RUN pip install -r requirements.txt

WORKDIR ./myapp
CMD gunicorn --bind 0.0.0.0:8000 myapp.wsgi:application

EXPOSE 8000

postgres 연결 myapp/myapp/setting.py db연결정보 추가(HOST는 postgres컨테이너 아이디)

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'postgres',
        'USER': 'postgres',
        'PASSWORD': 'mysecretpassword',
        'HOST': 'd084bca41460',
        'PORT': '5432',
    }
}

nginx default.config (nginx 80 포트로 받는 요청을 django container name이 djangotest 인 컨테이너 8000포트로 전송하도록 세팅)

upstream myweb{
server djangotest:8000;
        }

server{
    listen 80;
    server_name localhost;

    location /{
            proxy_pass http://myweb;
    }
}

Dockerfile (nginx 설정을 default.conf로 설정)

FROM nginx:1.25.3
RUN rm /etc/nginx/conf.d/default.conf
COPY default.conf /etc/nginx/conf.d/
CMD ["nginx", "-g", "daemon off;"]
