How do you install gateway.networking.k8s.io in autopilot clusters

[jlewi]

How do you make the [K8s Gateway Resource](https://cloud.google.com/kubernetes-engine/docs/how-to/deploying-gateways#enable-gateway-existing-cl...) on an existing autopilot cluster?

The docs say to upgrade the cluster to a version of 1.26. I did that via the UI. Here's a screenshot.

However, the CRD doesn't appear to be there. The only gateway resource I have is the ISTIO gateway.

kubectl get crd | grep gateway

gateways.networking.istio.io                      2023-04-26T18:15:39Z

kubectl api-resources --verbs=list --namespaced -o name | grep gateway

gateways.networking.istio.io

I ran the following command 

!gcloud container clusters update dev \
--gateway-api=standard \
--region=us-west1

And that appears to have worked.

kubectl get crd | grep gateway 
gatewayclasses.gateway.networking.k8s.io          2023-04-26T22:05:40Z
gateways.gateway.networking.k8s.io                2023-04-26T22:05:40Z
gateways.networking.istio.io                      2023-04-26T18:15:39Z
gcpgatewaypolicies.networking.gke.io              2023-04-26T22:05:40Z
httproutes.gateway.networking.k8s.io              2023-04-26T22:05:41Z
referencegrants.gateway.networking.k8s.io         2023-04-26T22:05:41Z

So it looks like the documentation is incorrect and you need to run that command for Autopilot clusters as well.

This bit me today on a cluster running 1.27 😢

Thanks for posting the solution... I wish the docs would get fixed to call this out for autopilot clusters
