How to set service.name and have it show up in Jaeger?

[ghost]

I have read several discussions that would seem to be related to this question but I am not sure what the trick is to setting service.name. I am assuming that this is used in the Jaeger UI where I am seeing "unknown_service" for everything I do.

sdk::resource::ResourceAttributes attributes = {{"service.name", "my_service_name"}};
auto resource = sdk::resource::Resource::Create(attributes);
auto provider = nostd::shared_ptr<trace::TracerProvider>(new sdk::trace::TracerProvider(std::move(processor), resource));
