I’ve been getting external-dns up and running, and I noticed a message in the external-dns logs (Ignoring changes to ‘*’ because a suitable Azure DNS zone was not found.). I believe it’s caused by the Gateway that is created during Istio installation (pasted below). What is this Gateway configured for? I might be missing something, but I can’t see where it is used.
