Introduction

Docker has revolutionized the way we deploy applications. In this tutorial, we'll walk through setting up a Django application with Docker, PostgreSQL, and Nginx.

Prerequisites

• Docker and Docker Compose installed
• Basic knowledge of Django
• Understanding of containerization concepts

Setting Up the Environment

First, let's create our Dockerfile:

FROM python:3.13-slim
WORKDIR /app
COPY requirements.txt .
RUN pip install -r requirements.txt
COPY . .
EXPOSE 8000
CMD ["gunicorn", "config.wsgi:application"]

Docker Compose Configuration

Our docker-compose.yml file orchestrates multiple services including Django, PostgreSQL, and Nginx for production-ready deployment.

This setup provides a robust foundation for any Django project with proper separation of concerns and scalability.
