+# Docker Auto Restart
+## Description
+
+This role automates the restart process for Docker Compose instances within a specified directory. It deploys a Python script that checks for the presence of docker-compose.yml files and restarts the associated services—using a hard restart for certain directories if needed.
+
+## Overview
+
+Optimized for containerized environments, this role:
+- Sets up the necessary directories and scripts for restarting Docker Compose instances.
+- Configures a systemd service (and optionally a timer) to execute the restart script.
+- Handles both standard restarts and hard restarts for specific containers (e.g., for Mailu).
+
+## Purpose
+
+The primary purpose of this role is to ensure that all Docker Compose services are restarted consistently, resolving issues that may arise from partial restarts. This helps maintain overall service stability and minimizes downtime.
+
+## Features
+
+- **Automated Detection:** Scans a specified parent directory for docker-compose.yml files.
+- **Service Restart:** Executes a Python script to restart Docker services via docker-compose.
+- **Conditional Hard Restart:** Applies a hard restart procedure for specific directories (e.g., Mailu).
+- **Systemd Integration:** Configures a systemd service and optionally a timer for scheduled restarts.
+
+
+
+# Context
+This role was implemented to address the classic issue: ["Have you tried turning it off and on again?"](https://www.youtube.com/watch?v=rksCTVFtjM4). The problem initially arose with the `fetchmail` container in [Mailu](.roles/docker/mailu), which fails if only some containers, and not the full docker-compose composition, are restarted.
+
+## Credits 📝
+This role was developed with the assistance of [ChatGPT](https://openai.com/chatgpt), including insights and optimizations from this [conversation](https://chatgpt.com/share/674c6870-fcc4-800f-a19e-b20621b24317). Special thanks for providing guidance on error handling, Ansible best practices, and Python integration.
