1. After cloning, as prerequisite install the vagrant & hypervisor on your local ubuntu machine

   $ sudo apt-get update
   $ sudo apt-get install vagrant
   $ sudo apt-get install virtualbox

2. Once you've installed both we can spinup the vm's using vagrant

   $ vagrant up

   This will take sometime, Since new vm's will be booted & bootstrapped using the script common.sh for installing crio, kubeadm, kubelet, kubectl with version of 1.28 k8's installed.

3. Once it's done. Let's initialize the masternode.

   $ vagrant ssh master-node
   $ kubeadm init --config=kubeadm-config.yaml

   This will take sometime, After getting a successfull initialization message

   To start using your cluster, you need to run the following as a regular user:

  mkdir -p $HOME/.kube
  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
  sudo chown $(id -u):$(id -g) $HOME/.kube/config

Alternatively, if you are the root user, you can run:

  export KUBECONFIG=/etc/kubernetes/admin.conf

Use the join command in the other 2 vm's
