error building (k8s) DNS provider

Error message

error building (k8s) DNS provider: %v

What it means

gceCloudImplementation.DNS wraps clouddns.CreateInterface failure when kops needs the k8s dnsprovider interface for Google Cloud DNS on a GCE cluster. It fires when the cloud-dns provider cannot initialize (credentials/project issues) — callers performing DNS record management get this wrapped error.

Solutions

  1. Fix Application Default Credentials
  2. Verify the project and DNS API access
  3. Inspect the wrapped error
Defensive patterns

Strategy: try-catch
