Does Django Work With Kubernetes?
Django runs excellently on Kubernetes with proper containerization; this is a production-ready combination used by many large-scale applications.
Quick Facts
How Django Works With Kubernetes
Django and Kubernetes work together seamlessly because Django is stateless and containerizable. You package your Django application in a Docker container, then Kubernetes orchestrates multiple replicas, handles load balancing, rolling updates, and auto-scaling based on metrics. The developer experience involves creating a Dockerfile, defining Kubernetes manifests (Deployments, Services, ConfigMaps), and using tools like Helm for templating. Django's ASGI/WSGI servers (Gunicorn, uWSGI) run as container processes, and Kubernetes manages networking between containers. Static files and media are typically served from object storage (S3, GCS) rather than the container filesystem. Database connections should use environment variables for configuration, and you'll want to handle migrations carefully—typically running them as init containers or Jobs before deploying new versions. The main architectural consideration is ensuring your Django app is truly stateless: no session data stored locally, no file uploads to the container filesystem.
Best Use Cases
Django Dockerfile + Kubernetes Deployment
pip install django gunicorn# Dockerfile
FROM python:3.11-slim
WORKDIR /app
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt
COPY . .
RUN python manage.py collectstatic --noinput
CMD ["gunicorn", "--bind", "0.0.0.0:8000", "--workers", "4", "config.wsgi:application"]

Django migrations race conditions when multiple pod replicas initialize simultaneously
Fix: Run migrations as a separate Kubernetes Job that completes before deploying application Pods, or use init containers with proper locking mechanisms
Static files not found in production because containers are ephemeral and don't persist filesystem changes
Fix: Collect static files during Docker build phase, serve from CDN/object storage, or use whitenoise middleware for self-serving
Database connection leaks when Pods are terminated during rolling updates, causing connection pool exhaustion
Fix: Set appropriate CONN_MAX_AGE, implement connection pooling (PgBouncer), and configure preStop hooks to drain connections gracefully
Environment variable management becomes complex with secrets, ConfigMaps, and different deployment environments
Fix: Use sealed-secrets, External Secrets Operator, or cloud-native secret managers; avoid hardcoding in manifests
