Setting up local Kubernetes cluster using vagrant and ansible

I have followed this blog to setup local kubernetes cluster.
I did some required changes to run in my MAC book. Not very sure if those are required for other's.
Your local system is expected to be equipped with Vagrant, some Vagrant provider like Oracle Virtual Box and Ansible.
To create local cluster go inside the checked out folder and run vagrant up.

Once everything comes out successfully check the following

Run vagrant ssh k8s-master
Run kubectl get nodes
Expected :

 vagrant@k8s-master:~$ kubectl get nodes
 NAME         STATUS     ROLES    AGE     VERSION
 k8s-master   Ready      master   8m52s   v1.16.2
 node-1       Ready      <none>   3m42s   v1.16.2
 node-2       Ready   	<none>   33s     v1.16.2
