Traefik doesn't trigger obtaining cert from acme server

I would like to know if the traefik's behavior is expected/bug or I'm missing something.
My scecario:

  • in traefik I have set default wildcard cert - let's assume it's for *
  • deploying service (docker swarm) - with domain
    In this case traefik doesn't obtain the cert for deployed from acme

If is it the feature - then is it possible to force traefik to try to obtain a cert?

Thanks in advance,
