Vagrant Install
Assuming you have Vagrant (1.8+) installed with virtualbox (it may work
with vmware, but is untested) you should be able to launch a 3 node
Kubernetes cluster by simply running $ vagrant up.
This will spin up 3 VMs and install kubernetes on them. Once they are
completed you can connect to any of them by running
$ vagrant ssh k8s-0[1..3].
$ vagrant up

Customize Vagrant
You can override the default settings in the Vagrantfile either by directly modifying the Vagrantfile
or through an override file.
In the same directory as the Vagrantfile, create a folder called vagrant and create config.rb file in it.
You're able to override the variables defined in Vagrantfile by providing the value in the vagrant/config.rb file,
e.g.:
echo '$forwarded_ports = {8001 => 8001}' >> vagrant/config.rb
and after vagrant up or vagrant reload, your host will have port forwarding setup with the guest on port 8001.
Use alternative OS for Vagrant
By default, Vagrant uses Ubuntu 16.04 box to provision a local cluster. You may use an alternative supported operating system for your local cluster.
Customize $os variable in Vagrantfile or as override, e.g.,:
echo '$os = "coreos-stable"' >> vagrant/config.rb
The supported operating systems for vagrant are defined in the SUPPORTED_OS constant in the Vagrantfile.
