The IC pod consists of a single container, which includes the IC process, NGINX master process, and NGINX worker processes. The IC uses the Kubernetes API to get the latest Ingress resources created in the cluster and then configures NGINX according to those resources. The document also covers the differences for NGINX Plus and the architecture of the IC process[

Installation Guide - NGINX Ingress Controller
There are multiple ways to install the NGINX ingress controller: with Helm, using the project repository chart; with kubectl apply, using YAML manifests; with specific addons (e.g. for minikube or MicroK8s). On most Kubernetes clusters, the ingress controller will work without requiring any extra configuration.

Nginx Ingress: service "ingress-nginx-controller-admission" not found
We created a kubernetes cluster for a customer about one year ago with two environments; staging and production separated in namespaces. We are currently developing the next version of the application and need an environment for this development work, so we've created a beta environment in its own namespace.

Setup NGINX Ingress Controller | Rancher Desktop Docs
Rancher Desktop uses K3s under the hood, which in turn uses Traefik as the default ingress controller for your Kubernetes cluster. However, there are unique use cases where NGINX may be required or preferred. Below steps show how to use NGINX Ingress controller for a sample deployment.
