 # Install minikube on Linux
 # use this script to launch k8s-cluster on local and interact with Minikube install-minikube.sh
 $ git clone https://github.com/punitporwal07/minikube.git

 $ cd minikube
 $ chmod +x install-minikube.sh

 Now add your localuser as sudo-user, with root do the following -
