Kevin Veen-Birkenbach e09f561f0b Refactor run-once orchestration and bootstrap Mailu/Mastodon in a single deploy
- Replace legacy utils/run_once.yml with the new helpers utils/once_flag.yml and utils/once_finalize.yml
- Introduce utils/compose_up.yml to ensure docker-compose stacks are up and to flush handlers safely without coupling to run-once flags
- Migrate all affected roles (desk-*, dev-*, sys-ctl-*, sys-svc-*, web-app-*, web-svc-*, util-*) to the new run-once helpers
- Rework sys-svc-msmtp to auto-load Mailu once per deploy, check reachability, and reuse the running stack instead of requiring multiple playbook passes
- Adjust web-app-mailu to integrate cert deployment, handler flushing, and run-once handling so Mailu is fully initialized in a single deploy
- Improve Matomo, CDN, logout and CSP/health-check related roles to cooperate with the new compose_up / once_* pattern
- Simplify alarm/backup/timer/service orchestration (sys-ctl-alm-*, sys-bkp-provider, sys-timer-cln-bkps, etc.) by moving run-once logic into dedicated 01_core.yml files
- Update integration tests so utils/once_flag.yml and utils/once_finalize.yml are recognised as valid run-once providers, keeping the global run_once_* guarantees consistent
- Align frontend injection and service dependencies so Mastodon- and Mailu-related services can be brought up coherently within a single deployment cycle rather than several iterations

Docker Healer 🩺

Description

This Ansible role automatically restarts Docker Compose configurations with exited or unhealthy containers on Arch Linux systems. It ensures the stability of containerized workloads by recovering from common error conditions like port binding issues.

Overview

Tailored for Arch Linux, this role monitors containers for failure states and initiates a controlled restart of affected Compose configurations. If port conflicts prevent recovery, the role stops the affected stack, restarts Docker, and recreates the container environment.

Purpose

The purpose of this role is to provide automated healing for Docker Compose environments, minimizing manual recovery effort and reducing downtime.

Features

  • Container Health Monitoring: Detects unhealthy or exited containers.
  • Automated Recovery: Restarts failed containers and resolves port binding issues.
  • Run-once Setup Logic: Ensures idempotent execution by controlling task flow with internal flags.
  • System Role Integration: Seamlessly integrates with Infinito.Nexus system maintenance logic.
