Traefik Ingress rewrite-target does nothing

I have a backend service which responds to / but I want it to run on the ingress route myhost.com/overview. No matter which configuration I try, traefik does not strip the path /overview away - I can see the backend getting /overview.

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: registry-ingress
  namespace: ingress
  annotations:
    kubernetes.io/ingress.class: traefik
    traefik.ingress.kubernetes.io/rewrite-target: /
spec:
  rules:
    - host: myhost.com
      http:
        paths:
        - path: /overview
          pathType: Prefix
          backend:
            service:
              name: overview
              port:
                number: 8079

I have tried several variations of this:

traefik.ingress.kubernetes.io/rewrite-target: /$1
...
        - path: /overview(.*)

But these lead to 404 on the ingress /overview requests do not reach the backend.

In summary I want https://myhost.com/overview/ to hit the backend at /.

Traefik does not support the traefik.ingress.kubernetes.io/rewrite-target annotation. See the list of available annotations here: https://doc.traefik.io/traefik/routing/providers/kubernetes-ingress/#annotations

But your goal can be achieved using the StipPrefix middleware.
