# MIG

This folder contains the Ansible role to deploy the Meta Infinite Graph for Infinito.Nexus.

## Description

This role sets up the [Ansible Meta Infinite Graph](https://github.com/kevinveenbirkenbach/meta-infinite-graph) for Infinito.Nexus. The Meta Infinite Graph visualizes all dependencies and relationships between Infinito.Nexus roles, making the overall infrastructure structure transparent and easy to understand.

## Overview

The Meta Infinite Graph is an essential tool for analyzing, auditing, and maintaining the modular structure of the Infinito.Nexus ecosystem. It provides a clear overview of all roles and how they are interconnected.

## Cosmos

The diagram places MIG 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).

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

- Automatic deployment of the Meta Infinite Graph web application
- Shows all dependencies and connections between Infinito.Nexus roles
- Useful for documentation and architecture transparency

## Quick Setup

### Development

Clone, set up the workstation, and deploy MIG 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-app-mig full_cycle=false
```

### Production

Run the published image to provision the inventory and deploy MIG to a managed server (the mounted volume persists the inventory):

```bash
APP=web-app-mig
HOST=<your-server>
DOMAIN=<your-domain>
TLS_MODE=self_signed
SSH_PUBLIC_KEY="<your-ssh-public-key>"

docker run --rm -it \
  -v "$PWD/inventories:/etc/infinito.nexus/inventories" \
  -e APP="$APP" -e HOST="$HOST" -e DOMAIN="$DOMAIN" -e TLS_MODE="$TLS_MODE" -e SSH_PUBLIC_KEY="$SSH_PUBLIC_KEY" \
  ghcr.io/infinito-nexus/core/debian bash -c '
    INVENTORY=/etc/infinito.nexus/inventories/production
    infinito administration inventory provision "$INVENTORY" \
      --inventory-file "$INVENTORY/devices.yml" \
      --host "$HOST" \
      --include "$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'
```

## Persona contract opt-outs

This role declares `PERSONA_ADMINISTRATOR_BLOCKED` and `PERSONA_BIBER_BLOCKED` in `templates/playwright.env.j2` for the same reason. `meta/services.yml` pins `sso.enabled: false` and `sso.shared: false`: MIG serves the pre-rendered Meta Infinite Graph over its own compose stack and has no login surface, no accounts, and no authenticated state at all. Consequently the env file renders no `ADMIN_USERNAME`, `ADMIN_PASSWORD`, `BIBER_USERNAME` or `BIBER_PASSWORD` for the shared helpers to read.

The `dashboard` service in `meta/services.yml` is only a consumer tile pointing at MIG's canonical domain; it does not host MIG. The role's contract is fully carried by the reachability, canonical-domain and content-type scenarios in `files/playwright/playwright.spec.js`, plus the guest persona. The path back to the generic personas is an authenticated MIG surface, which upstream does not have.
