Kevin Veen-Birkenbach 716ebef33b Refactor task includes and update variable handling for Ansible 2.20 migration
This commit updates multiple roles to ensure compatibility with Ansible 2.20.
Several include paths and task-loading mechanisms required adjustments,
as Ansible 2.20 applies stricter evaluation rules for complex Jinja expressions
and no longer resolves certain relative include paths the way Ansible 2.18 did.

Key changes:
- Replaced legacy once_finalize.yml and once_flag.yml with the new structure
  under tasks/utils/once/finalize.yml and tasks/utils/once/flag.yml.
- Updated all include_tasks statements to use 'path_join' with playbook_dir,
  ensuring deterministic and absolute file resolution across roles.
- Fixed all network helper includes by converting direct relative paths such as
  'roles/docker-compose/tasks/utils/network.yml' to proper Jinja-evaluated paths.
- Normalized MATOMO_* variable names for consistency with the updated variable
  scope behavior in Ansible 2.20.
- Removed deprecated patterns that were implicitly supported in Ansible 2.18
  but break under the more strict variable and path resolution model in 2.20.

These changes are part of the full migration step required to ensure the
infinito-nexus roles remain stable, deterministic, and forward-compatible with
Ansible 2.20.

sys-svc-dns

Bootstrap and maintain DNS prerequisites for your web stack on Cloudflare.

This role validates credentials and (by default) ensures:

  • A (and optional AAAA) records on the apex (@) for all base SLD domains
  • Wildcard A/AAAA records (*.parent) for parent hosts via sys-dns-wildcards
  • (Optional) CAA records for Lets Encrypt (kept as a commented block you can re-enable)

Runs once per play and is safe to include in stacks that roll out many domains.


What it does

  1. Validate CLOUDFLARE_API_TOKEN is present (early fail if missing).
  2. Ensure apex A/AAAA exist for every base SLD in SYS_SVC_DNS_BASE_DOMAINS:
    • Writes @ Anetworks.internet.ip4
    • Writes @ AAAAnetworks.internet.ip6 (only if global and present)
  3. (Optional) CAA records for all base SLDs (commented in the tasks; enable if you want CAA managed here).
  4. Ensure wildcard parent DNS exists (*.parent derived from children):
    • Delegates to sys-dns-wildcards
    • Creates A (and AAAA if enabled) wildcard records on the Cloudflare zone, optionally proxied.
