How to Set up Nginx Ingress Controller on Kubernetes

Setting up an Nginx Ingress Controller on Kubernetes is a crucial step in managing and directing traffic within your cluster efficiently. Ingress controllers provide a way to route external HTTP/S traffic to the appropriate services, enhancing the overall performance and security of your Kubernetes environment. In this article, we'll guide you through the process of setting up the Nginx Ingress Controller on Kubernetes, ensuring a seamless deployment for your applications.


Before we dive into the installation process, make sure you have the following prerequisites in place:

  1. A running Kubernetes cluster: Ensure that your Kubernetes cluster is up and running. If not, set up a cluster using tools like Minikube or kind.

  2. kubectl: Install the Kubernetes command-line tool (kubectl) to interact with your cluster.

Step 1: Deploy Nginx Ingress Controller using Helm:

Helm is a package manager for Kubernetes that simplifies the deployment process. Use the following commands to install the Nginx Ingress Controller:

# Add the Nginx Ingress Helm repository
helm repo add ingress-nginx

# Update the Helm repositories
helm repo update

# Install the Nginx Ingress Controller
helm install nginx-ingress ingress-nginx/ingress-nginx

Step 2: Verify Nginx Ingress Controller Installation:

After the installation is complete, check the status of the Nginx Ingress Controller pods:

kubectl get pods -n <namespace>

Ensure that all pods are in the 'Running' state.

Step 3: Expose Services with Ingress Resources:

To expose your services externally, create an Ingress resource. Below is a basic example:

kind: Ingress
name: example-ingress
- host:
- path: /
pathType: Prefix
name: example-service
number: 80

Apply the Ingress resource using:

kubectl apply -f ingress.yaml

Step 4: Access Your Application:

Once the Ingress resource is applied, access your application using the specified host ( in the example). Make sure to update your DNS records or modify your hosts file to point to the cluster's IP address.

Additional Configuration Options:

Explore additional configuration options for the Nginx Ingress Controller to tailor it to your specific requirements. Some common configurations include TLS termination, rewriting URLs, and setting up custom error pages.

Congratulations! You have successfully set up the Nginx Ingress Controller on Kubernetes, allowing you to efficiently manage external traffic to your services. Feel free to explore more advanced configurations and features offered by Nginx Ingress to optimize and secure your Kubernetes deployments.
