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
