Nginx Certbot Automation

🔥 Description

This role automates the setup of an automatic Let's Encrypt certificate renewal system for Nginx using Certbot. It ensures that SSL/TLS certificates are renewed seamlessly in the background and that Nginx reloads automatically after successful renewals.

📖 Overview

Optimized for Archlinux systems, this role installs the certbot-nginx package, configures a dedicated systemd service for certificate renewal, and integrates with a sys-timer to schedule periodic renewals. After a renewal, Nginx is reloaded to apply the updated certificates immediately.

  • Seamless Nginx Reload: Reloads the Nginx service automatically after successful renewals.
  • Systemd Integration: Manages renewal operations reliably with systemd and sys-alm-compose.
