Does Google Cloud HTTP Load Balancer supports gRPC?

Question

I'm trying to figure out if Google Cloud HTTP Load Balancer that is attached to the GKE cluster when an ingress point is created supports grpc

so far, all I can find is this documents showing how to use envoy to expose a service

https://cloud.google.com/solutions/exposing-grpc-services-on-gke-using-envoy-proxy

but nothing that works with the ingress preconfigured on Google Cloud

Answer 1

Yes it does. You will need to enable HTTP/2 support in the HTTP Load balancer. Here are instructions on how to setup HTTP/2 for load balancing with Ingress in GKE.
