Alternative to Deploy NONRTRIC in Minikube
There is an alternative way, described in the procedure below to run NonRT-RIC kubenetes cluster in Minikube running on Oracle Virtual Box with Ubuntu 22.04.
Via an installation script that brings up Minikube and allow to deploy NonRT-RIC cluster on it. Besides, the Kubernetes GUI could be started to see overall deployment.
Prerequisite
VirtualBox version 6.1. (Can be downloaded from this page Download VirtualBox)
Install Ubuntu 22.04
Ubuntu version 22.04. (Can be downloaded from this page Download Ubuntu)
