World Wide Web

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 DOMAIN_PRIMARY

  • 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.

Cosmos

The diagram places World Wide Web 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).

    subgraph deps [Dependencies]
        dep_svc_net_tor["svc-net-tor 🐳🐝"]
    end
    subgraph role [web-opt-rdr-www]

        svc_tor["tor"]
    end
    dep_svc_net_tor -. "0..1" .-> svc_tor

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.

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. 🐛

Quick Setup

Development

Clone, set up the workstation, and deploy World Wide Web onto the local stack:

git clone https://github.com/infinito-nexus/core.git
cd core
make onboard
make compose-deploy mode=reinstall apps=web-opt-rdr-www full_cycle=false

Production

Install World Wide Web directly onto the target machine: clone the repository, install the OS prerequisites and the repository toolchain, then deploy against localhost over a local connection (no SSH, no container):

git clone https://github.com/infinito-nexus/core.git
cd core
bash scripts/install/package.sh
make install
source scripts/meta/env/load.sh

APP=web-opt-rdr-www
DOMAIN=<your-domain>
TLS_MODE=self_signed
SSH_PUBLIC_KEY="<your-ssh-public-key>"
INVENTORY=inventories/production
infinito administration inventory provision "$INVENTORY" \
  --inventory-file "$INVENTORY/devices.yml" \
  --host localhost \
  --include "$APP" \
  --vars "{\"TLS_MODE\": \"$TLS_MODE\", \"DOMAIN_PRIMARY\": \"$DOMAIN\", \"users\": {\"administrator\": {\"authorized_keys\": [\"$SSH_PUBLIC_KEY\"]}}}"
infinito administration deploy dedicated "$INVENTORY/devices.yml" \
  --password-file "$INVENTORY/.password" \
  --diff -vv
