Nginx HTTPS Certificate Retrieval

🔥 Description

This role automates the retrieval of Let's Encrypt SSL/TLS certificates using Certbot for domains served via Nginx. It supports both single-domain and wildcard certificates, and can use either the DNS or webroot ACME challenge methods.

📖 Overview

Designed for Archlinux systems, this role handles issuing certificates per domain and optionally cleans up redundant certificates if wildcard certificates are used. It intelligently decides whether to issue a standard or wildcard certificate based on the domain structure and your configuration.

Key Features

Single Domain and Wildcard Support: Handles both individual domains and wildcard domains (*.example.com).
DNS and Webroot Challenges: Dynamically selects the correct ACME challenge method.
Certificate Renewal Logic: Skips renewal if the certificate is still valid.
Optional Cleanup: Deletes redundant domain certificates when wildcard certificates are used.
Non-Interactive Operation: Fully automated using --non-interactive and --agree-tos.

🎯 Purpose

The Nginx HTTPS Certificate Retrieval role ensures that your Nginx-served domains have valid, automatically issued SSL/TLS certificates, improving web security without manual intervention.

🚀 Features

ACME Challenge Selection: Supports DNS plugins or webroot method automatically.
Wildcard Certificate Management: Issues wildcard certificates when configured, saving effort for subdomain-heavy deployments.
Safe Cleanup: Ensures that no unused certificates are left behind.
Flexible Control: Supports mode_test for staging environment testing and mode_cleanup for cert cleanup operations.
