Getting Started with Kibana and nginx Ingress Controller in Kubernetes

Getting Started with Kibana and nginx Ingress Controller in Kubernetes

Kubernetes, the open-source platform for automating deployment, scaling, and management of containerized applications, has become a go-to solution for many data scientists. Today, we’ll explore how to set up Kibana with an nginx ingress controller in a Kubernetes environment.

What is Kibana?

Kibana is an open-source data visualization and exploration tool used for log and time-series analytics, application monitoring, and operational intelligence use cases. It offers powerful and easy-to-use features such as histograms, line graphs, pie charts, heat maps, and built-in geospatial support. Also, it provides tight integration with Elasticsearch, a popular analytics and search engine.

What is nginx Ingress Controller?

In Kubernetes, an Ingress is an API object that manages external access to services within a cluster. nginx Ingress Controller is a daemon that interprets these Ingress rules and manages the traffic routing. It provides an HTTP and HTTPS routing solution to services based on the domain name and URL paths.

Prerequisites

Before we start, ensure you have the following:

• A running Kubernetes cluster
• kubectl, the Kubernetes command-line tool
• Helm, the package manager for Kubernetes

Step 1: Install nginx Ingress Controller

First, we need to install the nginx Ingress Controller. We’ll use Helm to simplify the process. Run the following commands:

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

Step 2: Install and Configure Kibana

Next, we’ll install Kibana using Helm:

helm repo add elastic https://helm.elastic.co
helm repo update
helm install my-kibana elastic/kibana

After installation, configure Kibana to use the nginx Ingress Controller. Create a file named kibana-ingress.yaml and add the following:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: kibana-ingress
  annotations:
    kubernetes.io/ingress.class: nginx
spec:
  rules:
  - host: kibana.mydomain.com
    http:
      paths:
      - pathType: Prefix
        path: "/"
        backend:
          service:
            name: my-kibana-kibana
            port:
              number: 5601

Replace kibana.mydomain.com with your domain. Apply the configuration with:

kubectl apply -f kibana-ingress.yaml

Step 3: Access Kibana

You should now be able to access Kibana at http://kibana.mydomain.com. If you encounter any issues, check the status of your services and Ingress:

kubectl get services
kubectl get ingress

Conclusion

In this post, we’ve walked through setting up Kibana with an nginx Ingress Controller in a Kubernetes environment. This setup allows you to leverage the powerful data visualization capabilities of Kibana, while efficiently managing traffic routing with nginx.

Remember, while this guide provides a basic setup, both Kibana and nginx offer a wide range of configurations to suit your specific needs. Always refer to the official documentation for more detailed information.
