Defining backend scheme in ingress in traefik

Traefik Traefik v3 (latest)
1

Trying to get the ingress provider (ingress api, not Traffics CRD IngressRoute) up and running.

The last point i need to solve is how to define, if a service upstream should use TLS and if so, if certificates should be validated.

I found that there are 2 options:

  1. Using annotations on the service as by Kubernetes Ingress Routing Configuration - Traefik using `traefik.ingress.kubernetes.io/service.serversscheme` / `traefik.ingress.kubernetes.io/service.serverstransport` as by Kubernetes Ingress Routing Configuration - Traefik
  2. if the service has a specific name / port as by Kubernetes Ingress Routing Configuration - Traefik

My problem here is, that i usually do not define the services or at least, it would need either chart support or more effort to annotate the services with traefik specific annotations.

Are there any options to rather define this on the “Ingress” CRD itself, similar as it is supported in the IngressRout offerered by Traefik.

Any advice would be awesome!
