owned-dns Specification

Purpose

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

Requirements

Requirement: Owner-local DNS configuration

The tf_setup 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 before adoption and SHALL remain enabled by default after authorized adoption. Adoption SHALL bind existing provider records to the owner’s state without adding, changing, replacing, or deleting DNS records. Subsequent reconciliation of unchanged declarations SHALL preserve owned and unrelated records.

Scenario: Inspect the preparatory configuration

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

Scenario: Inspect the adopted configuration

  • WHEN the adopted root is evaluated with default inputs
  • THEN it reads this owner’s declaration and enables managed DNS records
  • AND the package contains the module and declaration inputs

Scenario: Adopt existing records

  • WHEN the owner applies a reviewed saved import plan through //infra/flux/tf_setup:dns.apply
  • THEN the owner state binds each declared record to its existing provider identity
  • AND the reviewed adoption plan proposes no record additions, changes, replacements, or deletions

Scenario: Reconcile unchanged declarations

  • WHEN the adopted root plans and applies unchanged declarations through its //infra/flux/tf_setup wrappers
  • THEN it makes no DNS resource changes
  • AND owned records retain their declared values and views while unrelated records remain unchanged

Requirement: Scoped DNS execution and offline checks

The DNS wrappers SHALL select src_infra_flux through the repository AL flow and keep secret values in injected variables. The dns.plan, dns.show, and dns.apply targets SHALL select dns=1 and retain the owner’s setup backend; plans SHALL target module.dns and apply SHALL require a reviewed saved plan. Ordinary setup wrappers SHALL retain their service authentication behavior. Real DNS credentials and Vault policy grants SHALL be prerequisites for operational Terraform calls. RouterOS DNS credentials SHALL remain isolated from unrelated RouterOS resources. The package SHALL expose a format test without live credentials. DNS-targeted validation SHALL NOT establish unrelated VM or service health.

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 an authorized operator selects the owner’s DNS wrapper
  • THEN it selects DNS credential injection through the owner AppRole and setup backend
  • AND its scoped plan and saved-plan apply cover DNS and its dependencies
  • AND disabled DNS resources do not imply offline provider configuration
