Many applications running Kubernetes are web applications that need to serve HTTP traffic. For scenarios like this, Kubernetes has so called ingress objects that can be used to direct traffic to microservices. Under the hood, the Ingress Controller is powered by tools like Traefik, Istio or nginx.

Install nginx to your Kubernetes cluster

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

That’s it. You’re now ready to create ingress resources. To learn how to expose an application using nginx-ingress, read the following article:
