 [GKE assigns a separate IP address to each `Ingress`](https://cloud.google.com/kubernetes-engine/docs/concepts/ingress#limitations), but we can have a single `Gateway` with an IP address and then any quantity of `HTTPRoute`. This is a design choice for GKE, and not a limitation of kubernetes.
 
+If you need to use `Ingress`, we can achieve the same efficiency for IP addresses by using the nginx ingress controller. This can be enabled by passing `-var ingress_type=nginx`.

 Clean Up
 ========
 Just like we did a 2-stage apply by toggling the `cluster_exists` variable, we will need to do a 2-stage destroy. First we tear down any kubernetes resources by running *apply* with the `cluster_exists` variable set to `false`. Then we can destroy the entire project.
