## Prerequisites
| Composant | Version min. | Recommande |
|-----------|-------------|------------|
| Docker + Compose | 24.x | 25.x |
| RAM | 16 Go | 32 Go |
| CPU | 4 cores | 8 cores |
| Disque | 50 Go SSD | 200 Go NVMe |
| GPU (optionnel) | - | NVIDIA RTX 3060+ pour LLM rapide |
| OS | Ubuntu 22.04 / Debian 12 | Ubuntu 24.04 |
## 1. Installation rapide
```bash
# Cloner le depot
git clone https://github.com/yourorg/Kill_LIFE.git
cd Kill_LIFE
# Deployer la stack complete
bash deploy/factory/deploy_factory.sh
```
Le script `deploy_factory.sh` effectue :
- Pull des images Docker (Mascarade, Ollama, Qdrant, InfluxDB, Grafana, Mosquitto)
- Configuration des variables d'environnement
- Demarrage de la stack Docker Compose
- Health checks avec retry
- Import automatique du dashboard Grafana
## 2. Configuration des variables d'environnement
Creer un fichier `.env` a la racine :
```bash
# --- Mascarade / LLM ---
MASCARADE_PORT=8000
DEFAULT_PROVIDER=ollama
OLLAMA_HOST=http://localhost:11434
OLLAMA_MODEL=mistral:7b-instruct-v0.3-q4_K_M
# --- OPC-UA ---
OPCUA_ENDPOINT=opc.tcp://192.168.1.10:4840
# --- MQTT ---
MQTT_BROKER=localhost:1883
MQTT_USERNAME=
MQTT_PASSWORD=
# --- InfluxDB ---
INFLUXDB_URL=http://localhost:8086
INFLUXDB_TOKEN=my-super-secret-token
INFLUXDB_ORG=factory
INFLUXDB_BUCKET=sensors
# --- Grafana ---
GRAFANA_ADMIN_PASSWORD=admin
# --- Odoo (optionnel) ---
ODOO_URL=http://odoo.local:8069
ODOO_DB=production
ODOO_USERNAME=api_user
ODOO_PASSWORD=api_password
```
## 3. Deploiement par composant
### 3.1 Mosquitto (broker MQTT)
```bash
# Si deja un broker MQTT interne, pointer MQTT_BROKER dessus.
# Sinon, le compose le demarre automatiquement.
docker compose -f deploy/factory/factory-stack.yml up -d mosquitto
# Test :
mosquitto_pub -t "test/hello" -m "world"
mosquitto_sub -t "test/#" -C 1
```
### 3.2 OPC-UA
Le serveur OPC-UA est fourni par l'automate/SCADA existant. Configurer `OPCUA_ENDPOINT` vers celui-ci.
Pour tester sans materiel :
```bash
# Lancer le simulateur OPC-UA integre
pip install asyncua
python tools/industrial/test_opcua_simulator.py
```
### 3.3 InfluxDB + Grafana
```bash
docker compose -f deploy/factory/factory-stack.yml up -d influxdb grafana
# Creer le bucket "sensors" dans InfluxDB :
influx bucket create -n sensors -o factory -r 90d
# Le dashboard Grafana est importe automatiquement depuis :
# deploy/factory/grafana-dashboard.json
```
### 3.4 Ollama + Mascarade
```bash
docker compose -f deploy/factory/factory-stack.yml up -d ollama mascarade
# Telecharger le modele LLM
docker exec ollama ollama pull mistral:7b-instruct-v0.3-q4_K_M
# Verifier
curl http://localhost:8000/health
curl http://localhost:11434/api/tags
```
### 3.5 MCP Servers industriels
```bash
# OPC-UA MCP server
bash tools/industrial/run_opcua_mcp.sh
# MQTT MCP server
bash tools/industrial/run_mqtt_mcp.sh
```
Les MCP servers sont enregistres dans Cline/Claude Code via les settings JSON.
## 4. Agents industriels
Les 3 agents sont configures dans Mascarade avec routing par domaine :
| Agent | Role | Provider |
|-------|------|----------|
| `factory-copilot` | Chatbot operateur, interroge OPC-UA/MQTT | ollama (local) |
| `maintenance-predictor` | Analyse series temporelles, alertes | ollama (local) |
| `log-analyst` | Lecture logs MES/ERP, rapports auto | ollama (local) |
Le routing Mascarade (strategy: domain) dirige les requetes vers Ollama sur le Tower pour garantir que les donnees industrielles ne quittent pas le reseau local.
## 5. Pipeline de donnees
### 5.1 Capteurs -> MQTT -> InfluxDB
Les capteurs publient sur MQTT. Un bridge Telegraf ou Node-RED ecrit dans InfluxDB :
```bash
# Avec Node-RED (deja configure) :
# Voir deploy/factory/nodered-flows.json
# Ou avec Telegraf :
# [[inputs.mqtt_consumer]]
# servers = ["tcp://localhost:1883"]
# topics = ["factory/#"]
# [[outputs.influxdb_v2]]
# urls = ["http://localhost:8086"]
```
### 5.2 Detection d'anomalies
```bash
# Mode demo (sans InfluxDB) :
python tools/industrial/influxdb_ml_pipeline.py --demo
# Mode production :
python tools/industrial/influxdb_ml_pipeline.py --measurements temperature pressure vibration
# Sortie JSON pour integration :
python tools/industrial/influxdb_ml_pipeline.py --demo --json
```
### 5.3 Connecteur Odoo/OpenMES
```bash
# Lister les ordres de fabrication
python tools/industrial/odoo_connector.py list-mo
# Creer un OF
python tools/industrial/odoo_connector.py create-mo --product "Widget A" --qty 100
# Resume production
python tools/industrial/odoo_connector.py summary --days 30
```
## 6. Securite reseau
Recommandations pour un deploiement on-premise :
- **Isolation reseau** : La stack Factory 4.0 doit etre sur un VLAN dedie, separe du reseau bureautique
- **Pas d'acces internet** : Ollama tourne en local, aucune donnee ne sort du site
- **TLS MQTT** : Configurer Mosquitto avec certificats TLS pour le trafic capteur
- **OPC-UA Security** : Activer le mode `SignAndEncrypt` avec certificats X.509
- **Authentification** : Tous les services (Grafana, InfluxDB, Odoo) doivent avoir des credentials non-default
- **Firewall** : N'ouvrir que les ports necessaires entre les VLANs (1883, 4840, 8086, 3000, 8000)
## 7. Monitoring et maintenance
```bash
# Health check global
curl http://localhost:8000/health # Mascarade
curl http://localhost:11434/api/tags # Ollama
curl http://localhost:8086/health # InfluxDB
curl http://localhost:3000/api/health # Grafana
# Logs
docker compose -f deploy/factory/factory-stack.yml logs -f --tail=100
# Donnees simulees pour test
python deploy/factory/simulate_data.py
```
## 8. Mise a jour
```bash
cd Kill_LIFE
git pull
docker compose -f deploy/factory/factory-stack.yml pull
docker compose -f deploy/factory/factory-stack.yml up -d
bash deploy/factory/deploy_factory.sh # re-run health checks + grafana import
```
