gRPC C++ CSM Hello World Example

This CSM example builds on the Hello World Example and changes the gRPC client and server to test CSM observability.

Configuration

The client takes the following command-line arguments -

• target - By default, the client tries to connect to the xDS “xds:///helloworld:50051” and gRPC would use xDS to resolve this target and connect to the server backend. This can be overridden to change the target.
• prometheus_endpoint - Endpoint used for prometheus. Default value is localhost:9464

The server takes the following command-line arguments -

• port - Port on which the Hello World service is run. Defaults to 50051.
• prometheus_endpoint - Endpoint used for prometheus. Default value is localhost:9464

Building

From the gRPC workspace folder:

Client:

docker build -f examples/cpp/csm/observability/Dockerfile.client

Server:

docker build -f examples/cpp/csm/observability/Dockerfile.server

To push to a registry, add a tag to the image either by adding a -t flag to docker build command above or run:

docker image tag ${sha from build command above} ${tag}

And then push the tagged image using docker push
