I need to identify all requests of my applications, puting a header with their names, like deploy service-one put a header Referer=service-one, when is calling another application. I want to do this on the infrastructure layer, because I have most than 100 applications and I don't want to change all those codes. I use k8s with linkerd.
I can't use Istio. It's a service to service communication, I can't use ingress too
I tried to do this using linkerd ServiceProfile and HTTPRoutes, but they just act in incoming requests not the outbounds
