Django Dockerfile Generator: Complete Guide

Django Production Dockerfile Best Practices

Django requires running collectstatic at build time to gather all static assets into STATIC_ROOT. Set the DJANGO_SETTINGS_MODULE environment variable and use '--noinput' to avoid interactive prompts during the Docker build.

FROM python:3.11-slim
WORKDIR /app
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt
COPY . .
ENV DJANGO_SETTINGS_MODULE=myproject.settings
RUN python manage.py collectstatic --noinput
EXPOSE 8000
CMD ["gunicorn", "myproject.wsgi:application", "--bind", "0.0.0.0:8000"]

How to Use

Runtime Pre-Selected

This page has pre-configured the generator for Django. Adjust port, base image, and environment variables as needed.

Toggle Multi-Stage Build

Enable multi-stage builds to separate the build environment from the runtime, drastically reducing image size.

Enable Non-Root Security

Check the non-root user option to run your container as a non-privileged user for production security.

Copy & Use

Switch between Dockerfile, docker-compose.yml, and .dockerignore tabs to copy each file.

Frequently Asked Questions

How do I Dockerize a Django application?+

Use a Python slim base image, install dependencies from requirements.txt, run 'python manage.py collectstatic --noinput' to bundle static files, then start the application with Gunicorn: 'gunicorn project.wsgi:application --bind 0.0.0.0:8000'.

Should I use Gunicorn or Uvicorn for Django in Docker?+

For traditional Django (WSGI), use Gunicorn. For Django with ASGI (channels, async views), use Uvicorn or Daphne. Gunicorn is the most battle-tested choice for standard Django deployments.
