Hi everyone,
I was wondering if somebody could help me out, I am very new to grpc and
xds.
I noticed there was sample xds_greeter and xds_greeter_client sample apps
in the helloworld examples of grpc and I just wanted to try it out.
*Using Istio 1.13.0 and Kubernetes v1.23.3*
*GRPC_TRACE=api ./xds_greeter_server *
