Wildcard without sans

Hi, it's possible to generate wildcard cert by default certResolver without setting main and sans labels for all containers? (with DNS-1 provider Cloudflare)

Without labels:

  • "traefik.http.routers.whoami.tls.domains[0].main=mydomain.com"
  • "traefik.http.routers.whoami.tls.domains[0].sans=*.mydomain.com"


Docker containers (defaultRule: 'Host({{ .Name }}.mydomain.com)'):

Name: test -> Url: test.mydomain.com
Name: grafana -> Url: grafana.mydomain.com
Name: testing.com (with label Host(`testing.com`)) -> Url: testing.com
Name: dash.testing.com (with label Host(`dash.testing.com`)) -> Url: dash.testing.com

Containers test and grafana - Traefik will generate cert *.mydomain.com
Containers testing.com and dash.testing.com - Traefik will generate cert *.testing.com

Can someone help me please? :frowning:
