Routing Dask Dashboard Traffic Through NGINX Ingress in Kubernetes

In the world of data science, managing distributed computing tasks can be a daunting challenge. Dask, a flexible library for parallel computing in Python, has emerged as a popular solution for this. However, when running Dask on Kubernetes, you might want to route the Dask dashboard traffic through NGINX Ingress for better security and control. This blog post will guide you through the process.

Prerequisites

Before we start, ensure you have the following:

  • A running Kubernetes cluster
  • Helm installed
  • Familiarity with Dask, Kubernetes, and NGINX

Step 1: Install Dask

First, we need to install Dask on our Kubernetes cluster. We can do this using the Dask Helm chart. Run the following command:

helm repo add dask https://helm.dask.org/
helm repo update
helm install my-release dask/dask

This will install Dask with a default configuration. You can customize the configuration to suit your needs.

Step 2: Install NGINX Ingress Controller

Next, we need to install the NGINX Ingress Controller. This can be done using the NGINX Ingress Controller Helm chart:

helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm repo update
helm install my-nginx ingress-nginx/ingress-nginx

Step 3: Configure Ingress Resource

Now, we need to create an Ingress resource to route traffic to the Dask dashboard. Create a file called dask-ingress.yaml with the following content:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: dask-ingress
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
spec:
  rules:
  - host: dask.example.com
    http:
      paths:
      - pathType: Prefix
        path: "/"
        backend:
          service:
            name: my-release-dask-jupyter
            port:
              number: 80

Replace dask.example.com with your domain. This configuration will route all traffic from dask.example.com to the Dask dashboard.

Apply the configuration with the following command:

kubectl apply -f dask-ingress.yaml

Step 4: Verify the Setup

To verify that everything is working as expected, navigate to dask.example.com in your web browser. You should see the Dask dashboard.

If you encounter any issues, check the logs of the NGINX Ingress Controller:

kubectl logs -l app.kubernetes.io/name=ingress-nginx -n ingress-nginx

Conclusion

Routing Dask dashboard traffic through NGINX Ingress in Kubernetes provides better control over traffic and enhances security. While this guide provides a basic setup, you can further customize it to fit your specific needs. For example, you can add SSL/TLS, use a different domain for the Dask dashboard, or add authentication.

Remember, the key to successful data science is not just about having powerful tools, but also about effectively managing and controlling these tools. By routing Dask dashboard traffic through NGINX Ingress, you can achieve just that.
