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.

Automated Telegram Alerts for Service Failures

Description

This role installs and configures the necessary components for sending notifications via systemd when a service fails. It sets up the sys-ctl-alm-telegram service and configures parameters and customizable templates for sending messages through Telegram.

Overview

Optimized for real-time alerts, this role is a key component of the overall sys-ctl-alm-compose suite. It ensures that, upon failure of a critical service, a Telegram message is automatically sent to notify administrators and enable prompt troubleshooting.

Purpose

The primary purpose of this role is to provide a robust solution for automated Telegram notifications in a systemd environment. By integrating with Telegrams Bot API and using customizable message templates, it delivers clear and timely alerts about service failures, thereby enhancing system observability and reliability.

Features

  • Service Installation & Configuration: Installs and configures necessary components (including the curl package).
  • Customizable Templates: Supports tailored Telegram message templates for service failure notifications.
  • Secure Notifications: Leverages systemd to trigger alerts automatically when services fail.
  • Suite Integration: Part of the sys-ctl-alm-compose suite which includes related roles such as sys-ctl-alm-email and others.
