ClusterDomain

Here’s an example of a fully configured ClusterDomain resource:

apiVersion: sme.sap.com/v1alpha1
kind: ClusterDomain
metadata:
  name: common-external-domain
spec:
  domain: my.example.com
  ingressSelector:
    app: istio-ingressgateway
    istio: ingressgateway
  tlsMode: Simple        # Simple (default) or  Mutual
  dnsMode: Subdomain     # Wildcard or Subdomain or None (default)
  dnsTarget: public-ingress.cluster.domain # Optional

• The dnsTarget field is optional. If specified, it will be used; otherwise, it will be derived from the Istio Ingress Gateway via ingressSelector.
• Gateway and DNSEntry will be created in the namespace where the cap-operator is installed, while Certificates will be created in the namespace where Istio Ingress Gateway is present.
