Ondemand plugin & k8s and ingressroute


i'm struggling to get the ondeman plugin (v1.3.0) to work with my k8s setup and ingressroute.

I configured traefik, i configured the middleware and if i open the ondemand endpoint in browser i got redirected to the ondemand plugin error page:
"...dial tcp:lookup traefik-ondemand_service on <CLOUD_DNS_IP>: no such host.


Any ideas ?

Does anyone know a complete example on how to get this working under k8s ?

PS: it seems that "gchr.io" does not exits anymore so i used the image @ docker-hub but "acouvreur/traefik-ondemand-service" is older than 2 months....

thx in advance,
