# Redirector

## Description

This Ansible role configures NGINX to perform 301 redirects from one domain to another. It handles SSL certificate retrieval for the source domains and sets up the NGINX configuration to redirect to the specified target domains.

## Overview

This role configures Nginx to perform 301 redirects based on a list of source→target domain mappings.

## Cosmos

The diagram places Redirector 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

- **Automated provisioning:** Configured by Ansible without manual steps.
- **Well-known passthrough:** every source domain serves the files of its own subdirectory `<domain>/` of the shared well-known directory (`lookup('nginx', 'directories.data.well_known')`) under `/.well-known/`; any other request, a missing well-known file included, gets the 301.

## Quick Setup

### Development

Clone, set up the workstation, and deploy Redirector onto the local stack:

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

### Production

Install Redirector 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):

```bash
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-domains
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
```
