# Docker Compose Certificate Sync Service

## Description

Keeps Docker Compose services updated with fresh Let’s Encrypt certificates via a systemd oneshot service and timer.

## Overview

Installs a small script and a systemd unit that copy certificates into your Compose project and trigger an NGINX hot-reload (fallback: restart) to minimize downtime.

## Cosmos

The diagram places Docker Compose Certificate Sync Service in the Infinito.Nexus cosmos: the components it deploys (capabilities), the central services it consumes (dependencies), and its outward reach (federation and bridged external networks).

    end
```

Solid `1:1` edges are fixed relationships; dashed `0..1` edges are conditional (enabled only in matching deployments); red `0..0` edges are turned off in this role. Node markers show the role's deploy modes (💻 host, 🐳 compose, 🐝 swarm); ❌ marks a service that is explicitly turned off, and ⚙️ an Ansible role dependency declared in `meta/main.yml`.

## Features

- Automatic certificate sync into the Compose project
- Mailu-friendly filenames (`key.pem`, `cert.pem`)
- NGINX hot-reload if available, otherwise restart
- Runs on a schedule you define
