I'm using Traefik as IngressRoute.
With kubectl api-resources it is defined as:
NAME SHORTNAMES APIVERSION NAMESPACED KIND
...
ingressroutes traefik.containo.us/v1alpha1 true IngressRoute
...
My problem is that in Kubernetes Dashboard only ingress resources can be viewed, therefore ingressroute resources is not displayed.
How to implement the ability to see ingressroute resources instead of ingresses?
Kubernetes Dashboard does not have the ability to display Traefik IngressRoute, the same way it shows Ingress, without changing it's source code.
If you want, you can create feature request in dashboard GitHub repo, and follow Improve resource support #5232 issue. Maybe in the future such feature will be added.
In the meantime, you can use Traefik's own dashboard.
