Linux worker node is required and two are recommended because many default
cluster-addons (e.g., `kube-dns`) need to run on Linux nodes. The master control
plane only runs on Linux.

```bash
export NUM_NODES=2  # number of Linux nodes
export NUM_WINDOWS_NODES=2
export KUBE_GCE_ENABLE_IP_ALIASES=true
export KUBERNETES_NODE_PLATFORM=windows
export LOGGING_STACKDRIVER_RESOURCE_TYPES=new
```

```bash
gcloud container clusters \
  create ${CLUSTER_NAME} \
  --zone ${ZONE} \
  --project ${PROJECT_ID} \
  --cluster-version ${CLUSTER_VERSION} \
  --machine-type ${MACHINE_TYPE} \
  --num-nodes ${NUM_NODES} \
  --enable-kubernetes-alpha \
  --no-enable-legacy-authorization
 ```

* `CLUSTER_NAME`: Whatever suits your fancy, 'istio-e2e' is a good choice.
* `ZONE`: 'us-central1-f' is a good value to use.
