In this post, we demonstrate performance testing the NGINX Ingress Controller for Kubernetes, focusing on RPS, SSL/TLS, and throughput. I successfully set up Proxy Protocol between the LB and my ingress controller. They are set in the container spec of the nginx-ingress-controller Deployment manifest. Kubernetes currently supports a number of Ingress controllers including Contour, HAProxy based ingress controller jcmoraisjr/haproxy-ingress, NGINX Ingress Controller for Kubernetes, and Traefik. This chart bootstraps an nginx-ingress deployment on a Kubernetes cluster using the Helm package manager. Leave Protocol set to TCP. I did all of this in an AKS environment in Azure but the steps would be exactly the same for self hosted kubernetes or any other platform like EKS. Luckily, Nginx Ingress controller already has a route /metrics at port10254 that exposes a bunch of metrics in prometheus format ( here is an example curlrequest to the nginx metrics endpoint to see a list of what metrics are exposed). The NodePort type exposes the service on a static port on each node. Kubernetes has become the de facto standard for managing containerized applications, with many enterprises adopting it in their production environments. The Ingress controller will connect to the Kubernetes API and will listen to events like create, delete, update, patch for objects of the kind Ingress.
