August 25, 2025 - CKS External Hostname Controller changes

Enhancements to the CKS External Hostname Controller for coreweave.app DNS record allocation

Update CKS The CKS External Hostname Controller has changed the way it reports DNS names for services running on CKS.

  • Prior to August 25, 2025: The controller mutated the service.beta.kubernetes.io/external-hostname annotation to long format if it was specified in short format.

  • Now: The controller no longer mutates the annotation. Instead, the FQDN and its allocation status are set in the .status.conditions field on the Service object, specifically under the ExternalRecords type.

No changes are required to your manifests or annotations. Only the method for retrieving the name has changed. Both short and long formats are still acceptable in the annotation.
