```

This script will provision a cluster suitable for production use, where there is a ring of 3 dedicated etcd nodes: 1 kubernetes master and 2 kubernetes nodes. The `kube-00` VM will be the master, your work loads are only to be deployed on the nodes, `kube-01` and `kube-02`. Initially, all VMs are single-core, to ensure a user of the free tier can reproduce it without paying extra. I will show how to add more bigger VMs later.
If you need to pass Azure specific options for the creation script you can do this via additional environment variables e.g.

```
AZ_SUBSCRIPTION=<id> AZ_LOCATION="East US" ./create-kubernetes-cluster.js
# or
AZ_VM_COREOS_CHANNEL=beta ./create-kubernetes-cluster.js
```
