1. Vue d'ensemble

Cette cartographie présente l'architecture Docker complète du jumeau numérique Smart City (Martinique), incluant les conteneurs, images, réseaux et ports exposés.

2. Flux de données principal

Pipeline Orion-LD (Fonctionnel ✅)

Simulator → MQTT Brokers (Mosquitto/EMQX/BunkerM) → IoT Agents → Orion-LD → QuantumLeap → CrateDB (standard) → Grafana

Pipeline Stellio (En cours de debug ⚠️)

Simulator → MQTT Brokers → IoT Agents → Stellio Context Broker → QuantumLeap-Stellio → CrateDB-Stellio → Grafana

6. État des Pipelines

✅ Pipeline Orion-LD (Opérationnel)

Statut : Entièrement fonctionnel
Données : CrateDB contient 6 tables avec données (etairqualityobserved a 6+ rows)
Grafana : Dashboard "Smart City - Air Quality (CrateDB)" fonctionnel
Subscription : Orion-LD → QuantumLeap active (lastNotification: 2026-05-07)

⚠️ Pipeline Stellio (Debug en cours)

Statut : Subscription créée, notifications reçues par QuantumLeap-Stellio
Problème : Données ne persistent pas dans CrateDB-Stellio (0 rows)
Cause probable : Mappage NGSI-LD → CrateDB incompatible
Subscription Stellio : urn:ngsi-ld:Subscription:0baad89d-1625-4b42-adc1-e841e04120ff
- Endpoint : http://smart-city-quantumleap-stellio:8668/v2/notify
- Format : NGSI-LD normalized

7. Services Web Accessibles

8. Connexions Clés

Traefik (:80/:443) : Reverse proxy pour tous les services exposés à l'hôte.
Brokers MQTT (Mosquitto :1883, EMQX :11883) : Réception des données du simulateur et des capteurs IoT.
Context Brokers (Orion-LD :1026, Stellio :8080) : Gestion des entités NGSI-LD.
Time-Series DB (CrateDB :4200 HTTP API, :5432 PostgreSQL) : Persistance des données pour Grafana.
Grafana (:3000) : Visualisation des données depuis CrateDB, InfluxDB, Prometheus.
