Running Django Application On Kubernetes

Imagine your Django application running in Kubernetes equipped with features of Kubernetes building a strong scalable and highly available application. In this post let's see how to dockerize and deploy a Django application on Kubernetes.

Deployment of an application always starts with having a nice and error-free application. To begin with, we will use a sample Django application with a sample view to provide Hello World! response.

<-- You can use your application or To follow along you can refer to the code from the below repo -->

Now that the application is ready, start with dockerizing and building an image. For this, we will create a requirements.txt of required modules.

 pip freeze > "requirements.txt" 

Lets write a recipe for our docker image in Dockerfile. The minimal configuration for Dockerfile is provided below you can modify it accordingly.

 FROM python:3.9.19-alpine RUN mkdir /DjangoHelloWorld WORKDIR /DjangoHelloWorld COPY / . RUN pip install -r requirements.txt EXPOSE 8000 CMD python manage.py runserver 0.0.0.0:8000 

To use SQLite database you can simply add migrations and make migration commands in CMD at the last line

 CMD python manage.py makemigrations && python manage.py migrate && python manage.py runserver 0.0.0.0:8000 

Done!✅ Build the docker image using below using Docker.

 docker build -t deepcodr/node-hello-world . 

That should create image for our application. Spin up a container if you want to test the application.

 docker run -dp 8000:8000 deepcodr/node-hello-world 

Test the application thoroughly and then we are ready for deployment.


Lets provide YAML configuration for Kubernetes Deployment and Service.

 apiVersion : v1 kind : Service metadata : name : djangohelloworld spec : selector : app : djangohelloworld type : LoadBalancer ports : - port : 8000 targetPort : 8000 --- apiVersion : apps/v1 kind : Deployment metadata : name : djangohelloworld spec : replicas : 1 selector : matchLabels : app : djangohelloworld template : metadata : labels : app : djangohelloworld spec : containers : - name : djangohelloworld image : deepcodr/django-hello-world ports : - containerPort : 8000 imagePullPolicy : Always 

The above configuration is sufficient to run our application with minimal configuration. Save the configuration and apply it with kubectl

 kubectl apply -f nodehelloworld.yaml 

This should create a service and deployment in Kubernetes.Lets view running pods and services in cluster.

 kubectl get svc kubectl get pods 

If you see a service and pods running. Your application should work 🎉


Test the application by hitting URL in browser. You will see your homepage.

Now that you know how to deploy Django application on Kubernetes 🗿, You are ready to build and configure more complex scenarios for Django with Kubernetes and explore Kubernetes in depth.
