[Story]: Airgapped NIM installation on k8s & openshift using Helm

Overview

As a user, I want to deploy NGINX Instance Manager on my air-gapped kubernetes/openshift cluster using Helm. This will allow me to seamlessly manage NIM's entire operational lifecycle

Which product or products does this request relate to?

NGINX Instance Manager

Description

NGINX documentation provides steps needed to deploy NGINX Instance Manager on a "disconnected" virtual machine (see https://docs.nginx.com/nginx-instance-manager/disconnected/offline-install-guide/). Several users share the same requirements/infrastructure:

• Kubernetes and/or Openshift clusters
• Fully airgapped / no Internet connectivity
• Helm used to manage all software deployments

The docs should include a section providing walkthrough guidance on how to deploy and upgrade NGINX Instance Manager by complying with these requirements

Acceptance criteria

As a user, I want to be able to follow the documentation to successfully deploy NGINX Instance Manager on my Internet-disconnected Kubernetes / Openshift cluster. The documentation should allow me to run NIM and publish it through my cluster's Ingress Controller (ideally, NGINX Ingress Controller) and optionally NGINX Gateway Fabric, that I might already be running in my cluster.
