When you want to run your Django applications on any machine and start in one click, you may use Docker. This way called as "serverless architecture". Docker allows you to run applications on any computer. It's very convenient and simple.

Complete structure of project:

demo_project/
    |
    |-- manage.py
    |
    |-- env/
    |
    |-- backend/
    |     |
    |     |-- asgi.py
    |     |-- __init__.py
    |     |-- settings.py
    |     |-- urls.py
    |     |-- wsgi.py
    |
    |-- core/
    |     |
    |     |-- admin.py
    |     |-- apps.py
    |     |-- __init__.py
    |     |-- models.py
    |     |-- tests.py
    |     |-- views.py
    |
    |-- Dockerfile
    |
    |-- docker-compose.yaml
    |
    |-- nginx/
          |
          |-- default.conf

1. Create Django application.

2. Create Dockerfile file in project's root folder and with this parameters:

FROM python:latest

ARG APP=/app

ENV PYTHONDONTWRITEBYTECODE=1
ENV PYTHONUNBUFFERED=1

WORKDIR ${APP}

COPY . .

RUN pip install --no-cache-dir -r requirements.txt

CMD ["gunicorn", "--bind", "0.0.0.0:8000", "--workers", "2", "backend.wsgi:application"]

3. Create docker-compose.yaml file in project's root folder and put following values:

services:

  database:
    container_name: database
    image: postgres:latest
    restart: unless-stopped
    shm_size: 128mb
    networks:
      - internal_network
    volumes:
      - /var/lib/postgresql/data/:/var/lib/postgresql/data/
    environment:
      POSTGRES_HOST: database
      POSTGRES_DB: database_name
      POSTGRES_USER: database_user
      POSTGRES_PASSWORD: password
    ports:
      - 127.0.0.1:5432:5432

  backend:
    container_name: backend
    build:
      context: .
      dockerfile: Dockerfile
    restart: unless-stopped
    depends_on:
      - database
    networks:
      - internal_network
    volumes:
      - ./media/:/app/media/
    ports:
      - 127.0.0.1:8000:8000

  nginx:
    container_name: nginx
    image: nginx
    restart: unless-stopped
    depends_on:
      - backend
    networks:
      - internal_network
    volumes:
      - ./nginx/default.conf:/etc/nginx/conf.d/default.conf
    ports:
    - '80:80'
    - '443:443'

networks:
  internal_network:
    ipam:
      driver: default
      config:
        - subnet: 172.18.0.0/24

4. Create default.conf file in "nginx" directory:

server {
    listen 80 default_server;

    server_name _;

    location / {
        proxy_set_header Host $host;
        proxy_pass http://backend:8000;
    }
}

5. Now start application:

docker compose up -d
