Traefik v2.2 Ingress Route example not working
I am trying to setup traefik ingress route using the configuration that is provided at https://docs.traefik.io/routing/providers/kubernetes-crd/
I can see traefik is up & running, can also see the dashboard. But I dont see the whoami service on dashboard and cannot access it via url.
crd.yaml

I am trying this example and got very stupid issue as mentioned. After hours to try, I figure out that the issue is at "match" rule.
-match: PathPrefix(`/whoami-app-api`)
-match: Host(`whoami.localhost`) && PathPrefix(`/notls`)
Match without host will work by http:localhost/<prefix>.
Match with a host that don't like real URI like ".net" ".com".. will work
Some host like real URI like abc.com, scx.net, the browser will try to reach it by DNS instead of local host "0.0.0.0", so it cant not reach our Traefik.
Otherwise, Host with single word won't work also. I don't know why. I think in URL, there are at least 2 words splitting by dot

I deployed the below code and the whoami is now accessible without any issues. Things I changed are, updated the CRD, RBAC with the latest available in Traefik and changed the apiVersion for the deployment to "apps/v1". Simply copy the below code all together and deploy on kubernetes. Once it is up access http://localhost/whoami-app-api.
