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.

Python-Yaml

Description

This Ansible role installs the python-yaml package on the target system. It ensures that the Python yaml library is available for loading and processing YAML files.

Overview

Optimized for simplicity and idempotency, this role provides:

  • Installation of the python-yaml package via the Pacman package manager.
  • A mechanism to run the installation only once.

Purpose

The purpose of this role is to reliably provide the Python-YAML package so that Python scripts can work with YAML files.

Features

  • YAML Support: Installs the python-yaml package, which supplies the yaml library for Python.
  • Idempotency: Uses a fact to ensure that the installation runs only on the first execution.
