### Setup
By default, the Vagrant setup will create a single master VM (called kubernetes-master) and one node (called kubernetes-node-1). Each VM will take 1 GB, so make sure you have at least 2GB to 4GB of free memory (plus appropriate free disk space). To start your local cluster, open a shell and run:
Setting up a cluster is as simple as running:
```sh
export KUBERNETES_PROVIDER=vagrant
curl -sS https://get.k8s.io | bash
```
Alternatively, you can download [Kubernetes release](https://github.com/kubernetes/kubernetes/releases) and extract the archive. To start your local cluster, open a shell and run:
```sh

The `KUBERNETES_PROVIDER` environment variable tells all of the various cluster management scripts which variant to use. If you forget to set this, the assumption is you are running on Google Compute Engine.

Vagrant will provision each machine in the cluster with all the necessary components to run Kubernetes. The initial setup can take a few minutes to complete on each machine.
If you installed more than one Vagrant provider, Kubernetes will usually pick the appropriate one. However, you can override which one Kubernetes will use by setting the [`VAGRANT_DEFAULT_PROVIDER`](https://docs.vagrantup.com/v2/providers/default.html) environment variable:

Each node in the cluster installs the docker daemon and the kubelet.
The master node instantiates the Kubernetes master components as pods on the machine.
