You need to install vagrant and virtualbox in advance for this to work.
For starting the cluster you can do it by running:
./up.sh
I recommend that you take a look at the up.sh to know what it does, then the Vagrantfile and then each script to see how you can quickly bootstrap a functional cluster (not production ready, but functional), also be aware that you will need at least 6 Gbs of free memory for the virtual machines.
Copy the kubeconfig to your machine, export its path as an environment variable and test it (give it at least 5 mins for the machines to boot, install everything and the kubelets to start running, you can watch the vagrant log).
vagrant ssh cluster1-master1 -c "sudo cat /root/.kube/config" > vagrant-kubeconfig
export KUBECONFIG="$(pwd)/vagrant-kubeconfig"
And then test it:
❯ kubectl get pods -A -o wide

You should see something like that, it means your cluster is up and running and it is fully functional.
