问题
I am trying to build a gRPC backend and trying to deploy it on an AppEngine Managed VM. Is HTTP/2 supported? If not, can I simply expose it on a separate port and disable health checks or should I deploy this on compute engine/container engine.
回答1:
At this point http/2 is not supported by Managed VMs. The best current solution is to run your http/2 server on a different port and specify the port number to forward in app.yaml (doc link).
You can keep health checking active on the default (8080) port if you want as long as you have an http endpoint listening there as well.
