refactor: improve service handling and introduce MODE_ASSERT
- Improved get_service_name filter plugin (clearer suffix handling, consistent var names).
- Added MODE_ASSERT flag to optionally execute validation/assertion tasks.
- Fixed systemd unit handling: consistent use of %I instead of %i, correct escaping of instance names.
- Unified on_failure behavior and alarm composer scripts.
- Cleaned up redundant logging, handlers, and debug config.
- Strengthened sys-service template resolution with assert (only active when MODE_ASSERT).
- Simplified timer and suffix handling with get_service_name filter.
- Hardened sensitive tasks with no_log.
- Added conditional asserts across roles (Keycloak, DNS, Mailu, Discourse, etc.).

These changes improve consistency, safety, and validation across the automation stack.

Webserver

This Ansible role installs and configures Nginx as a core HTTP/stream server on Arch Linux systems. It provides:

  • HTTP serving with MIME types, gzip compression, caching, and custom nginx.conf templating.
  • TCP/UDP stream support via the Nginx Streams module.
  • Directory management for configuration, sites-available/enabled, cache, and data.
  • Debugging helpers: log formats and instructions for general and detailed troubleshooting.

Features

  • Package installation of nginx and nginx-mod-stream.
  • Idempotent setup: tasks run only once per host.
  • Configurable reset and cleanup modes to purge and recreate directories.
  • Custom nginx.conf template with sensible defaults for performance and security.
  • Stream proxy support: includes stream block for TCP/UDP proxies.
  • Cache directory management: cleanup and recreation based on MODE_CLEANUP.

Debugging Tips

  • General logs: journalctl -f -u nginx
  • Filter by host: journalctl -u nginx -f | grep "{{ inventory_hostname }}"
  • Enable detailed format: set MODE_DEBUG: true and reload Nginx.
