How can I set up a redirect on GKE to GAE?

Question

I have a service deployed on GKE, with a a google cloud external load balancer. I would now like to winddown this service, but initially by redirecting to an app engine service. Is this possible via just the load balancer?

Answer 1

This can be achieved with a Serverless Network Endpoint Group (NEG).
You can find tutorial on creating such a setup here. Certain steps can be skipped since you already have the load balancer configured.
