owned-dns Specification

Purpose

Define NAS DNS management through the owner’s tf root, including canonical declarations, scoped credentials, and offline source checks before adopting live records.

Requirements

Requirement: Owner-local DNS configuration

The tf root SHALL consume this owner’s canonical dnsconfig.json through the shared DNS Terraform module, preserving declared record identities and views. DNS resources SHALL default to disabled until the authorized adoption revision and SHALL retain enabled ownership after existing records are imported into the owner’s state. Reconciliation against unchanged declarations and adopted state SHALL propose no record additions, changes, replacements, or deletions.

Scenario: Inspect the preparatory configuration

  • WHEN the checked-in root is evaluated with default inputs before its authorized adoption revision
  • THEN it reads this owner’s declaration and disables managed DNS records
  • AND the package contains the module and declaration inputs

Scenario: Adopt existing DNS records

  • WHEN the authorized adoption freezes the old central writers and enables the owner’s record management
  • THEN the owning root imports existing records by exact provider ID into its state while preserving their declared identities and views

Scenario: Inspect adopted source defaults

  • WHEN the adopted root uses its checked-in source defaults
  • THEN DNS ownership remains enabled and the package retains the module and canonical declaration inputs

Scenario: Reconcile existing DNS records

  • WHEN the owning root plans against its adopted state and unchanged declarations
  • THEN it proposes no record additions, changes, replacements, or deletions

Requirement: Scoped DNS execution and offline checks

The DNS wrapper SHALL select src_infra_nas through the repository AL flow and keep secret values in injected variables. DNS injection SHALL select the root’s existing Terraform stage label. Real DNS credentials and Vault policy grants SHALL be prerequisites for operational Terraform calls. RouterOS DNS credentials SHALL be isolated from unrelated RouterOS resources. The package SHALL expose a format test that does not authenticate to Vault or contact DNS providers.

Scenario: Validate the Terraform source

  • WHEN the package format test executes
  • THEN it checks the packaged Terraform configuration without live credentials
  • AND existing non-DNS authentication and backend paths remain unchanged

Scenario: Prepare an operational Terraform invocation

  • WHEN the wrapper selects its Terraform stage labels
  • THEN it selects DNS credential injection through the owner AppRole
  • AND disabled DNS resources do not imply offline provider configuration
