Working example for Proxyless Java-based gRPC setup with java-control-plane

[Oleg Cohen]

Greetings,

I am looking for a working example of how to set up a Java-based proxyless gRPC application. I would like to have the set up run locally, not in K8S. Not able to get the java-control-plane to work properly with sample Xds server and client.

Would appreciate any pointers to help with getting this work!

Thank you,

Oleg

grpc-java OSS has a unit test that implements an xds control plane

https://github.com/grpc/grpc-java/blob/master/xds/src/test/java/io/grpc/xds/XdsTestControlPlaneService.java

ping-pong test case: https://github.com/grpc/grpc-java/blob/master/xds/src/test/java/io/grpc/xds/FakeControlPlaneXdsIntegrationTest.java#L88

The example https://github.com/grpc/grpc-java/blob/master/examples/example-xds/README.md requires a control plane environment so it may not work locally automatically

Hope this helps,

Thank you for the info! It was helpful.

I continued to work on the example and finally managed to get a local xDS server built based on the java-control-plane. Really need to understand xDS at the protocol level. I am not entirely sure if my set up is correct, but the communication is established through the xDS server and I can now dig deeper to figure things out.

Definitely nice to have a proxyless setup!
