Infrastructure Code Controls Internal DNS Hostnames — Media Release Reconciliation
To manage internal DNS hostnames from infrastructure code, a media admin console must first separate platform-owned zones from customer-owned zones. Treating both as one writable pool makes the deployment model wrong before the first request is sent. TL;DR: keep the internal record set in the infrastructure repository, upsert it during deployment, then read the records back and diff them. The…
Infrastructure code should manage internal DNS hostnames by separating platform-owned zones from customer-owned zones. Treating them as a single writable pool is incorrect. The infrastructure repository should serve as the source of truth, with desired state upserted during deployment and then read back to diff against the actual records.
This approach prevents quiet drift caused by out-of-band edits to records. Only platform-owned zones should be managed through this method, or customer-owned zones if the customer has explicitly delegated control. Fast-changing names should be stored in a service registry. DNS should be kept simple and boring.
