I'm building an Istio-Datadog integration for distributed tracing.
I can see traces showing in Datadog, but I cannot associate them with the running pods, because there's no pod_name in the span. I would like to add that pod_name to spans generated by Istio, and see them in traces in Datadog. Is this possible?
When using manual tracing instrumentation (dd-tracer) in the microservices, adding a tag to span is a simple one-liner. I'd like to find an equivalent/central workaround for doing tracing via Istio.
