When setting a domain in the Kserve component, it is expected that the "domain" value is "subdomain.example.com" or similar. When customers supply a wildcard domain, this does not work as expected:

apiVersion: datasciencecluster.opendatahub.io/v1
kind: DataScienceCluster
metadata:
  name: default-dsc
spec:
  components:
    ...
    kserve:
      serving:
        ingressGateway:
          certificate:
            secretName: example-wildcard-certificate
            type: Provided
          domain: '*.subdomain.cloud.example.com'
        managementState: Managed
        name: knative-serving

The root cause is likely because the Operator is prepending "*." here: https://github.com/opendatahub-io/opendatahub-operator/blob/incubation/pkg/feature/serverless/loaders.go#L32

The expected format should either be documented or this case should be handled by the Operator.

Version-Release number of selected component (if applicable):

rhods-operator.2.7.0
OpenShift Container Platform 4.13.17
