What is Ingress Controller?
An Ingress Controller is a Kubernetes Component that is responsible for evaluation and processing of Ingress routes. An Ingress Controller acts as a Reverse Proxy and Load Balancer. An example of an Ingress Controller is Kubernetes Nginx Ingress Controller which is an Ingress Controller by Kubernetes.
In order to make the ingress routing rules to work, we need an implementation for Ingress and that implementation is called Ingress Controller. Therefore, before configuring Ingress to a Cluster, we would first have to install an Ingress Controller which is basically another Pod or set of Pods that run on your Node in your Kubernetes Cluster and is responsible for evaluation and processing of Ingress routes. The function of ingress controller is to evaluate all the rules that you have defined in your Cluster and manage all the redirections.
What Is Kubernetes Ingress ?
Ingress is a Kubernetes API object that is used to expose HTTP and HTTPS routes from outside the cluster to services inside the cluster. It provides a single entry point into a cluster hence making it simpler to manage applications and troubleshoot routing issues. In this article, we will discuss what Kubernetes Ingress is. what is an Ingress controller and How does it resolve the routing problem issue? we will guide you on step-by-step implementation of Kubernetes Ingress.
