I am working on a POC for Istio + gRPC, the Istio version is 1.6, but I could not see any gRPC traffic to my pods.
I suspect my Istio Gateway or VirtualService miss something, but I could not figure out what's wrong here? Could anybody help review my yaml file and correct me what's missing or wrong in my yaml?
