Nginx WWW Redirect 🌐

Description

Automates the creation of Nginx server blocks that redirect all www. subdomains to their non-www equivalents. Simple, idempotent, and SEO-friendly! 🚀

Overview

This role will:

  • Discover existing *.conf vhosts in your Nginx servers directory

  • Filter domains with or without your PRIMARY_DOMAIN

  • Generate redirect rules via the web-opt-rdr-domains role

  • Optionally include a wildcard redirect template (experimental) ⭐️

  • Clean up leftover configs when running in cleanup mode 🧹

All tasks are guarded by “run once” facts and MODE_CLEANUP flags to avoid unintended re-runs or stale files.

Purpose

Ensure that any request to www.example.com automatically and permanently redirects to https://example.com, improving user experience, SEO, and certificate management. 🎯

Features

  • Auto-Discovery: Scans your Nginx servers directory for .conf files. 🔍

  • Dynamic Redirects: Builds source: "www.domain" → target: "domain" mappings on the fly. 🔧

  • Wildcard Redirect: Includes a templated wildcard server block for www.* domains (toggleable). ✨

  • Cleanup Mode: Removes the wildcard config file when CERTBOT_FLAVOR is set to dedicated and MODE_CLEANUP is enabled. 🗑️

  • Debug Output: Optional MODE_DEBUG gives detailed variable dumps for troubleshooting. 🐛
