Hi everyone,
I was wondering if somebody could help me out, I am very new to grpc and
xds.
I noticed the following https://istio.io/latest/blog/2021/proxyless-grpc/
and wanted to do something similar.
I cloned grpc v1.43.0 and noticed that it contains xds_greeter and server
apps which I managed to build after some issues.
I have 2 containers with a service in between exposing port 50051 but for
some reason my client is unable to connect:

Could anybody provide me with some guidance, I would really appreciate any
comments.
