[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`. 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`. If you need to use the built-in ingress controller instead of nginx you can set `-var ingress_type=gce` but then each `Ingress` will cost 1 IP address.
