Currently, the domain mapping controller cannot process the URI of a broker, which contains a path that is currently not supported.

This means that, if you want to use a DomainMapping custom resource (CR) to map a custom domain to a broker, you must configure the DomainMapping CR with the broker’s ingress service, and append the exact path of the broker to the custom domain:

apiVersion: serving.knative.dev/v1alpha1
kind: DomainMapping
metadata:
  name: <domain-name>
  namespace: knative-eventing
spec:
  ref:
    name: broker-ingress
    kind: Service
    apiVersion: v1

The URI for the broker is then <domain-name>/<broker-namespace>/<broker-name>.
