To use Docker Compose with Django, you will need to create a Dockerfile and a docker-compose.yml file.

Here is an example Dockerfile that you can use as a starting point:

FROM python:3.8

ENV PYTHONUNBUFFERED 1

RUN mkdir /app
WORKDIR /app

COPY requirements.txt /app/
RUN pip install -r requirements.txt

COPY . /app/

This Dockerfile starts from the official Python Docker image and installs the required Python packages from requirements.txt. It then copies the rest of your Django project files into the container.

Next, you can create a docker-compose.yml file to define the services that make up your app. Here is an example docker-compose.yml file that you can use:

version: '3'

services:
  web:
    build: .
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/app
    ports:
      - "8000:8000"
    depends_on:
      - db
  db:
    image: postgres:10
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres
      POSTGRES_DB: postgres
    volumes:
      - postgres_data:/var/lib/postgresql/data/

volumes:
  postgres_data:

This file defines two services: web and db. The web service is built from the Dockerfile in the current directory and runs the Django development server on port 8000. The db service is a PostgreSQL database, which your Django app will use to store data.

To start your Django app with Docker Compose, run the following command:

$ docker-compose up

This will build the web service and start both the web and db services. Your Django app will be available at http://localhost:8000.

If you make any changes to your Django code, you will need to rebuild the web service for the changes to take effect. You can do this by running:

$ docker-compose build web

Thats all happy coding...
