description: CoreDNS is an open-source CNCF Graduated DNS server, released under the Apache 2.0 license.
  There is no commercial offering or paid plan from the upstream CoreDNS project. The software is free
  to download, run, and extend. Commercial support is sometimes available indirectly through Kubernetes
  distribution vendors that bundle CoreDNS, but no CoreDNS-branded paid plan exists.

notes: CoreDNS is an open-source CNCF Graduated project with no upstream commercial pricing. The DNS
  server itself runs in-cluster (or as standalone process) and is not metered. Reconciled is false
  because there is no provider-published pricing to reconcile against.
