Explicitly define the alternative port 55680 in OpenTelemetry collector configuration file in OpenTelemetry guide

[soul2zimate]

When I run the OpenTelemetry guide in https://quarkus.io/version/main/guides/opentelemetry, more specifically, configuring the OTLP gRPC endpoint via JVM arguments with the alternative port 55680 via command ./mvnw compile quarkus:dev -Djvm.args="-Dquarkus.opentelemetry.tracer.exporter.otlp.endpoint=http://localhost:55680"

I can see this error:

2022-01-27 17:35:28,399 SEVERE [io.ope.exp.otl.int.grp.DefaultGrpcExporter] (grpc-default-executor-1) Failed to export spans. Server is UNAVAILABLE. Make sure your collector is running and reachable from this network. Full error message:UNAVAILABLE: io exception

Although OTLP gRPC receiver alternative port 55680 is defined in docker-compose.yml, It turns out that the otel-collector-config.yaml is not receiving from that alternative port 55680. This change just explicitly define that alternative port 55680 in otlp receivers.

Thanks for taking the time to fix that. I wonder if https://github.com/quarkusio/quarkus-quickstarts/tree/main/opentelemetry-quickstart needs some love too? (be careful, use the development branch there)
