# Credentials Management System
Dieses System ermöglicht die zentrale Verwaltung und Aktualisierung von Credentials für installierte LXC-Container.
## Übersicht
Das Credentials-Management-System besteht aus drei Komponenten:
1. **Automatisches Speichern** - Credentials werden bei der Installation automatisch gespeichert
2. **Manuelles Speichern** - Credentials können aus JSON-Output extrahiert werden
3. **Update-System** - Credentials können zentral aktualisiert werden
---
## 1. Automatisches Speichern bei Installation
Bei jeder Installation wird automatisch eine Credentials-Datei erstellt:
```bash
# Installation durchführen
./install.sh --storage local-zfs --bridge vmbr0 --ip dhcp --vlan 90
# Credentials werden automatisch gespeichert in:
# credentials/<hostname>.json
```
**Beispiel:** `credentials/sb-1769276659.json`
---
## 2. Manuelles Speichern von Credentials
Falls Sie Credentials aus dem JSON-Output extrahieren möchten:
### Aus JSON-String
```bash
./save_credentials.sh --json '{"ctid":769276659,"hostname":"sb-1769276659",...}'
```
### Aus JSON-Datei
```bash
./save_credentials.sh --json-file /tmp/install_output.json
```
### Mit benutzerdefiniertem Ausgabepfad
```bash
./save_credentials.sh --json-file output.json --output my-credentials.json
```
### Mit formatierter Ausgabe
```bash
./save_credentials.sh --json-file output.json --format
```
---
## 3. Credentials aktualisieren
### Ollama-URL aktualisieren (z.B. von IP zu Hostname)
```bash
# Von IP zu Hostname wechseln
./update_credentials.sh --ctid 769276659 --ollama-url http://ollama.local:11434
```
### Ollama-Modell ändern
```bash
# Anderes Chat-Modell verwenden
./update_credentials.sh --ctid 769276659 --ollama-model llama3.2:3b
# Anderes Embedding-Modell verwenden
./update_credentials.sh --ctid 769276659 --embedding-model nomic-embed-text:v1.5
```
### Mehrere Credentials gleichzeitig aktualisieren
```bash
./update_credentials.sh --ctid 769276659 \
--ollama-url http://ollama.local:11434 \
--ollama-model llama3.2:3b \
--embedding-model nomic-embed-text:v1.5
```
### Aus Credentials-Datei aktualisieren
```bash
# 1. Credentials-Datei bearbeiten
nano credentials/sb-1769276659.json
# 2. Änderungen anwenden
./update_credentials.sh --ctid 769276659 --credentials-file credentials/sb-1769276659.json
```

## Updatebare Felder
### Sofort wirksam (kein Neustart erforderlich)
| Feld | Beschreibung | Beispiel |
|------|--------------|----------|
| `ollama.url` | Ollama Server URL | `http://ollama.local:11434` |
| `ollama.model` | Chat-Modell | `llama3.2:3b`, `ministral-3:3b` |
| `ollama.embedding_model` | Embedding-Modell | `nomic-embed-text:v1.5` |
**Diese Änderungen werden sofort in n8n übernommen!**
### Neustart erforderlich
| Feld | Beschreibung | Neustart-Befehl |
|------|--------------|-----------------|
| `postgres.password` | PostgreSQL Passwort | `pct exec <ctid> -- bash -c 'cd /opt/customer-stack && docker compose restart'` |
| `n8n.owner_password` | n8n Owner Passwort | `pct exec <ctid> -- bash -c 'cd /opt/customer-stack && docker compose restart'` |
---
## Workflow: Von IP zu Hostname wechseln
### Szenario
Sie möchten den Ollama-Server per Hostname statt IP ansprechen.
### Schritte
1. **DNS/Hostname einrichten**
```bash
# Sicherstellen, dass ollama.local auflösbar ist
ping ollama.local
```
2. **Credentials-Datei bearbeiten** (optional)
```bash
nano credentials/sb-1769276659.json
```
Ändern Sie:
```json
"ollama": {
"url": "http://ollama.local:11434",
...
}
```
3. **Update durchführen**
```bash
# Direkt per CLI
./update_credentials.sh --ctid 769276659 --ollama-url http://ollama.local:11434
# ODER aus Datei
./update_credentials.sh --ctid 769276659 --credentials-file credentials/sb-1769276659.json
```
4. **Verifizieren**
```bash
# In n8n einloggen und Ollama-Credential prüfen
# Oder Workflow testen
```
**Fertig!** Die Änderung ist sofort wirksam, kein Container-Neustart erforderlich.
---
## Sicherheit
### Credentials-Dateien schützen
```bash
# Verzeichnis-Berechtigungen setzen
chmod 700 credentials/
# Datei-Berechtigungen setzen
chmod 600 credentials/*.json
# Nur root kann lesen
chown root:root credentials/*.json
```
### Credentials aus Git ausschließen
Die `.gitignore` sollte enthalten:
```
credentials/*.json
!credentials/example-credentials.json
logs/*.log
```
---
## Backup
### Credentials sichern
```bash
# Alle Credentials sichern
tar -czf credentials-backup-$(date +%Y%m%d).tar.gz credentials/
# Verschlüsselt sichern
tar -czf - credentials/ | gpg -c > credentials-backup-$(date +%Y%m%d).tar.gz.gpg
```
### Credentials wiederherstellen
```bash
# Aus Backup wiederherstellen
tar -xzf credentials-backup-20260124.tar.gz
# Aus verschlüsseltem Backup
gpg -d credentials-backup-20260124.tar.gz.gpg | tar -xz
```
---
## Troubleshooting
### Credential-Update schlägt fehl
```bash
# n8n-Logs prüfen
pct exec 769276659 -- docker logs n8n
# n8n neu starten
pct exec 769276659 -- bash -c 'cd /opt/customer-stack && docker compose restart n8n'
# Update erneut versuchen
./update_credentials.sh --ctid 769276659 --ollama-url http://ollama.local:11434
```
### Credentials-Datei beschädigt
```bash
# JSON validieren
python3 -m json.tool credentials/sb-1769276659.json
# Aus Installation-JSON neu erstellen
./save_credentials.sh --json-file logs/sb-1769276659.log
```
### Ollama nicht erreichbar
```bash
# Von Container aus testen
pct exec 769276659 -- curl http://ollama.local:11434/api/tags
# DNS-Auflösung prüfen
pct exec 769276659 -- nslookup ollama.local
# Netzwerk-Konnektivität prüfen
pct exec 769276659 -- ping -c 3 ollama.local
```
---
## Best Practices
1. **Immer Credentials-Datei erstellen**
- Nach jeder Installation automatisch erstellt
- Manuell mit `save_credentials.sh` wenn nötig
2. **Credentials-Dateien versionieren**
- Änderungen dokumentieren
- Datum im Dateinamen: `sb-1769276659-20260124.json`
3. **Regelmäßige Backups**
- Credentials-Verzeichnis täglich sichern
- Verschlüsselt aufbewahren
4. **Hostname statt IP verwenden**
- Flexibler bei Infrastruktur-Änderungen
- Einfacher zu merken und zu verwalten
5. **Updates testen**
- Erst in Test-Umgebung
- Dann in Produktion
---
## Beispiel-Workflow
### Komplettes Beispiel: Neue Installation mit Credentials-Management
```bash
# 1. Installation durchführen
./install.sh --storage local-zfs --bridge vmbr0 --ip dhcp --vlan 90 > install_output.json
# 2. Credentials automatisch gespeichert in credentials/sb-<timestamp>.json
# 3. Credentials anzeigen
cat credentials/sb-1769276659.json | python3 -m json.tool
# 4. Später: Ollama auf Hostname umstellen

"components": {
"http_server": "deleted",
"location": "deleted",
"upstream": "deleted",
"upstream_server": "deleted"
},
"reconfigure": "ok"
}
```
### Löschreihenfolge
Das Script löscht die Komponenten in der richtigen Reihenfolge (von außen nach innen):
1. **HTTP Server** - Virtueller Host
2. **Location** - URL-Pfad-Konfiguration
3. **Upstream** - Load-Balancer-Gruppe

# 🚀 BotKonzept - Quick Start Guide
## In 5 Schritten zur funktionierenden Registrierung
---
## ✅ Voraussetzungen
- [ ] n8n läuft auf `https://n8n.userman.de`
- [ ] PostgreSQL/Supabase Datenbank verfügbar
- [ ] PVE20 Proxmox Server erreichbar
- [ ] SMTP-Server oder Amazon SES konfiguriert
---
## 📋 Schritt 1: Datenbank einrichten (5 Minuten)
```bash
# Auf Ihrem PostgreSQL/Supabase Server
psql -U postgres -d botkonzept < sql/botkonzept_schema.sql
```
**Oder in Supabase Dashboard:**
1. SQL Editor öffnen
2. Inhalt von `sql/botkonzept_schema.sql` kopieren
3. Ausführen
**Prüfen:**
```sql
SELECT table_name FROM information_schema.tables
WHERE table_schema = 'public';
```
Sollte zeigen: `customers`, `instances`, `emails_sent`, `subscriptions`, `payments`, `usage_stats`, `audit_log`
---
## 🔑 Schritt 2: n8n Credentials erstellen (10 Minuten)
### 2.1 PostgreSQL Credential
1. n8n → Credentials → **New Credential**
2. Typ: **Postgres**
3. Name: `Supabase Local`
4. Konfiguration:
```
Host: localhost (oder Ihr Supabase Host)
Port: 5432
Database: botkonzept
User: postgres
Password: [Ihr Passwort]
SSL: Enabled (für Supabase)
```
5. **Test** → **Save**
### 2.2 SSH Credential
**SSH Key generieren (falls noch nicht vorhanden):**
```bash
ssh-keygen -t ed25519 -C "n8n@botkonzept" -f ~/.ssh/n8n_pve20
ssh-copy-id -i ~/.ssh/n8n_pve20.pub root@192.168.45.20
```
**In n8n:**
1. Credentials → **New Credential**
2. Typ: **SSH (Private Key)**
3. Name: `PVE20`
4. Konfiguration:
```
Host: 192.168.45.20
Port: 22
Username: root
Private Key: [Inhalt von ~/.ssh/n8n_pve20]
```
5. **Save**
### 2.3 SMTP Credential
**Option A: Amazon SES**
1. Credentials → **New Credential**
2. Typ: **SMTP**
3. Name: `Postfix SES`
4. Konfiguration:
```
Host: email-smtp.eu-central-1.amazonaws.com
Port: 587
User: [SMTP Username]
Password: [SMTP Password]
From Email: noreply@botkonzept.de
```
5. **Save**
**Option B: Gmail (für Tests)**
```
Host: smtp.gmail.com
Port: 587
User: your-email@gmail.com
Password: [App-spezifisches Passwort]
From Email: your-email@gmail.com
```
---
## 📥 Schritt 3: Workflows importieren (5 Minuten)
### 3.1 Customer Registration Workflow
1. n8n → **"+"** → **Import from File**
2. Datei wählen: `BotKonzept-Customer-Registration-Workflow.json`
3. **Import**
4. Workflow öffnen
5. **Jeden Node prüfen** und Credentials zuweisen:
- "Create Customer in DB" → `Supabase Local`
- "Create Customer Instance" → `PVE20`
- "Save Instance to DB" → `Supabase Local`
- "Send Welcome Email" → `Postfix SES`
- "Log Email Sent" → `Supabase Local`
6. **Save**
7. **Activate** (Toggle oben rechts)
### 3.2 Trial Management Workflow
1. Import: `BotKonzept-Trial-Management-Workflow.json`
2. Credentials zuweisen
3. **Save** → **Activate**
---
## 🧪 Schritt 4: Testen (10 Minuten)
### 4.1 Webhook-URL kopieren
1. Workflow "Customer Registration" öffnen
2. Node "Registration Webhook" klicken
3. **Production URL** kopieren
- Sollte sein: `https://n8n.userman.de/webhook/botkonzept-registration`
### 4.2 Frontend aktualisieren
```bash
# customer-frontend/js/main.js
const CONFIG = {
WEBHOOK_URL: 'https://n8n.userman.de/webhook/botkonzept-registration',
// ...
};
```
### 4.3 Test mit curl
```bash
curl -X POST https://n8n.userman.de/webhook/botkonzept-registration \
-H "Content-Type: application/json" \
-d '{
"firstName": "Max",
"lastName": "Test",
"email": "max.test@example.com",
"company": "Test GmbH"
}'
```
**Erwartete Antwort:**
```json
{
"success": true,
"message": "Registrierung erfolgreich!",
"customerId": "...",
"instanceUrl": "https://sb-XXXXX.userman.de"
}
```
### 4.4 Prüfen
**Datenbank:**
```sql
SELECT * FROM customers ORDER BY created_at DESC LIMIT 1;
SELECT * FROM instances ORDER BY created_at DESC LIMIT 1;
```
**PVE20:**
```bash
pct list | grep sb-
```
**E-Mail:**
- Prüfen Sie Ihren Posteingang (max.test@example.com)
---
## 🌐 Schritt 5: Frontend deployen (5 Minuten)
### Option A: Lokaler Test
```bash
cd customer-frontend
python3 -m http.server 8000
```
Öffnen: `http://localhost:8000`
### Option B: Nginx
```bash
# Auf Ihrem Webserver
cp -r customer-frontend /var/www/botkonzept.de
# Nginx Config
cat > /etc/nginx/sites-available/botkonzept.de <<'EOF'
server {
listen 80;
server_name botkonzept.de www.botkonzept.de;
root /var/www/botkonzept.de;
index index.html;
location / {
try_files $uri $uri/ =404;
}
}
EOF
ln -s /etc/nginx/sites-available/botkonzept.de /etc/nginx/sites-enabled/
nginx -t
systemctl reload nginx
```
### Option C: Vercel/Netlify
```bash
cd customer-frontend
# Vercel
vercel deploy
# Netlify
netlify deploy
```
---
## ✅ Fertig!
Ihre Registrierung ist jetzt live! 🎉
### Nächste Schritte:
1. **SSL-Zertifikat** für botkonzept.de einrichten
2. **DNS-Records** konfigurieren (SPF, DKIM, DMARC)
3. **Amazon SES** aus Sandbox-Modus holen
4. **Monitoring** einrichten
5. **Backup-Strategie** planen
---
## 🆘 Probleme?
### Häufigste Fehler:
**1. "Credential not found"**
→ Prüfen Sie ob alle 3 Credentials erstellt sind
**2. "SSH connection failed"**
→ Prüfen Sie SSH Key: `ssh root@192.168.45.20`
**3. "Table does not exist"**
→ Führen Sie das Schema erneut aus
**4. "Email not sent"**
→ Prüfen Sie SMTP-Credentials und Absender-Verifizierung
### Detaillierte Hilfe:
- **Setup-Guide:** `REGISTRATION_SETUP_GUIDE.md`
- **Troubleshooting:** `REGISTRATION_TROUBLESHOOTING.md`
---
## 📊 Monitoring
### n8n Executions

-- Registrierungen heute
SELECT COUNT(*) FROM customers
WHERE DATE(created_at) = CURRENT_DATE;
-- Aktive Trials
SELECT COUNT(*) FROM customers
WHERE status = 'trial';
-- Letzte 5 Registrierungen
SELECT email, first_name, last_name, created_at
FROM customers
ORDER BY created_at DESC
LIMIT 5;
```

- Namen müssen exakt übereinstimmen: `Supabase Local`, `PVE20`, `Postfix SES`
### Problem 2: SSH-Verbindung schlägt fehl
**Lösung:**
```bash
# Auf n8n Server
ssh root@192.168.45.20
# Falls Fehler:
# 1. SSH Key generieren
ssh-keygen -t ed25519 -C "n8n@botkonzept"
# 2. Public Key kopieren
ssh-copy-id root@192.168.45.20
# 3. Testen
ssh root@192.168.45.20 "ls /root/customer-installer/"
```
### Problem 3: install.sh nicht gefunden
**Lösung:**
```bash
# Auf PVE20
cd /root
git clone https://backoffice.userman.de/MediaMetz/customer-installer.git
# Oder Pfad im Workflow anpassen
```
### Problem 4: Datenbank-Fehler
**Lösung:**
```bash
# Prüfen ob Tabellen existieren
psql -U postgres -d botkonzept -c "\dt"
# Falls nicht, Schema erneut ausführen
psql -U postgres -d botkonzept < sql/botkonzept_schema.sql
```
### Problem 5: E-Mail wird nicht versendet
**Lösung:**
**Für Amazon SES:**
1. Verifizieren Sie die Absender-E-Mail in AWS SES
2. Prüfen Sie SMTP-Credentials
3. Stellen Sie sicher, dass Sie aus dem Sandbox-Modus raus sind
**Für Postfix:**
```bash
# Auf dem Server
systemctl status postfix
journalctl -u postfix -f
# Test-E-Mail senden
echo "Test" | mail -s "Test" test@example.com
```
### Problem 6: Workflow wird nicht ausgeführt
**Lösung:**
1. Prüfen Sie ob Workflow aktiviert ist (grüner Toggle oben rechts)

```
# SPF
botkonzept.de. IN TXT "v=spf1 include:amazonses.com ~all"
# DKIM (von AWS SES bereitgestellt)
[selector]._domainkey.botkonzept.de. IN CNAME [value-from-ses]
# DMARC
_dmarc.botkonzept.de. IN TXT "v=DMARC1; p=quarantine; rua=mailto:dmarc@botkonzept.de"
```
---
## 🚨 Problem 7: JSON-Parsing-Fehler
### Symptome
- Fehler: "Unexpected token in JSON"
- Node "Parse Install Output" schlägt fehl
### Diagnose
```bash
# install.sh manuell ausführen und Output prüfen
cd /root/customer-installer
./install.sh --storage local-zfs --bridge vmbr0 --ip dhcp --vlan 90 2>&1 | tee test-output.log
# Ist der Output valides JSON?
cat test-output.log | jq .
```
### Lösungen
#### A) install.sh gibt Fehler aus
- Prüfen Sie die Logs in `/root/customer-installer/logs/`
- Beheben Sie die Fehler in install.sh
- Testen Sie erneut
#### B) Output enthält zusätzliche Zeilen
1. Öffnen Sie `install.sh`
2. Stellen Sie sicher, dass nur JSON auf stdout ausgegeben wird
3. Alle anderen Ausgaben sollten nach stderr gehen
#### C) DEBUG-Modus aktiviert
1. Prüfen Sie ob `DEBUG=1` gesetzt ist
2. Für Produktion: `DEBUG=0` verwenden
3. Im Workflow: Command ohne `--debug` ausführen
---
## 🚨 Problem 8: Workflow zu langsam / Timeout
### Symptome
- Frontend zeigt Timeout nach 30 Sekunden
- Workflow läuft noch, aber Frontend gibt auf
### Lösung
#### A) Timeout im Frontend erhöhen
```javascript
// In customer-frontend/js/main.js
const response = await fetch(CONFIG.WEBHOOK_URL, {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify(formData),
signal: AbortSignal.timeout(300000), // 5 Minuten
});
```
#### B) Asynchrone Verarbeitung
Ändern Sie den Workflow:
1. Webhook gibt sofort Response zurück
2. Instanz-Erstellung läuft im Hintergrund
3. E-Mail wird gesendet wenn fertig
**Workflow-Änderung:**
- Nach "Create Customer in DB" → Sofort Response
- Rest des Workflows läuft asynchron weiter
---
## 🚨 Problem 9: Doppelte Registrierungen
### Symptome
- Kunde registriert sich mehrmals
- Mehrere Einträge in `customers` Tabelle
- Mehrere LXC-Container
### Lösung
#### A) E-Mail-Unique-Constraint prüfen
```sql
-- Prüfen ob Constraint existiert
SELECT conname, contype
FROM pg_constraint
WHERE conrelid = 'customers'::regclass;
-- Falls nicht, hinzufügen
ALTER TABLE customers ADD CONSTRAINT customers_email_unique UNIQUE (email);
```
#### B) Workflow anpassen
Fügen Sie einen Check-Node hinzu:
```javascript
// Vor "Create Customer in DB"
const email = $json.body.email;
const existing = await $('Postgres').execute({
query: 'SELECT id FROM customers WHERE email = $1',
values: [email]
});
if (existing.length > 0) {
throw new Error('E-Mail bereits registriert');
}
```
---
## 🚨 Problem 10: Trial-Management läuft nicht
### Symptome
- Keine E-Mails an Tag 3, 5, 7
- Cron-Workflow wird nicht ausgeführt
### Diagnose
```bash
# In n8n: Executions filtern nach "Trial Management"
# Prüfen ob täglich um 9:00 Uhr ausgeführt wird
```
### Lösungen
#### A) Workflow nicht aktiviert
1. Öffnen Sie "BotKonzept - Trial Management"
2. Aktivieren Sie den Workflow (Toggle oben rechts)
#### B) Cron-Expression falsch
1. Öffnen Sie den Node "Daily at 9 AM"
2. Prüfen Sie die Expression: `0 9 * * *`
3. Testen Sie mit: https://crontab.guru/#0_9_*_*_*
#### C) Keine Trial-Kunden vorhanden
```sql
-- Prüfen
SELECT * FROM customers WHERE status = 'trial';
-- Test-Kunde erstellen
INSERT INTO customers (email, first_name, last_name, status, created_at)
VALUES ('test@example.com', 'Test', 'User', 'trial', NOW() - INTERVAL '3 days');
```

## Workflow Auto-Reload System
### Configuration
The system includes an automatic workflow reload mechanism that ensures workflows persist across container restarts:
- **Service:** `n8n-workflow-reload.service` (systemd)
- **Status:** ✅ Enabled and configured
- **Trigger:** Runs on LXC container start
- **Template:** `/opt/customer-stack/workflow-template.json`
- **Script:** `/opt/customer-stack/reload-workflow.sh`
### How It Works
1. On container restart, systemd triggers the reload service
2. Service waits for n8n to be ready
3. Automatically recreates credentials (PostgreSQL, Ollama)
4. Re-imports workflow from template
5. Activates the workflow
6. No manual intervention required
---
## Next Steps
### 1. Verify Ollama Connectivity ⚠️
```bash
# Test from Proxmox host
curl http://192.168.45.3:11434/api/tags
# Test from container
pct exec 769276659 -- bash -lc "curl http://192.168.45.3:11434/api/tags"
```
### 2. Configure NGINX Reverse Proxy
The installation script attempted to configure the NGINX reverse proxy on OPNsense. Verify:
```bash
# Check if proxy was configured
curl -I https://sb-1769276659.userman.de
```
If not configured, run manually:
```bash
./setup_nginx_proxy.sh --ctid 769276659 --hostname sb-1769276659 \
--fqdn sb-1769276659.userman.de --backend-ip 192.168.45.45 --backend-port 5678
```
### 3. Test RAG Workflow
#### Upload a Document
1. Access the upload form: `https://sb-1769276659.userman.de/form/rag-upload-form`
2. Upload a PDF document
3. Verify it's processed and stored in the vector database
#### Test Chat Interface
1. Access the chat webhook: `https://sb-1769276659.userman.de/webhook/rag-chat-webhook/chat`
2. Send a test message
3. Verify the AI responds using the uploaded documents
#### Verify Vector Storage
```bash
# Check documents in database
pct exec 769276659 -- bash -lc "docker exec customer-postgres psql -U customer -d customer -c 'SELECT COUNT(*) FROM documents;'"
# Check via PostgREST API
curl http://192.168.45.45:3000/documents
```
### 4. Monitor System Health
#### View Logs
```bash
# Installation log
tail -f logs/sb-1769276659.log
# Container logs (all services)
pct exec 769276659 -- bash -lc "cd /opt/customer-stack && docker compose logs -f"
# Individual service logs
pct exec 769276659 -- bash -lc "docker logs -f customer-postgres"
pct exec 769276659 -- bash -lc "docker logs -f customer-postgrest"
pct exec 769276659 -- bash -lc "docker logs -f n8n"
```
#### Check Container Status
```bash
# Container status
pct status 769276659
# Docker containers
pct exec 769276659 -- bash -lc "cd /opt/customer-stack && docker compose ps"
# Resource usage
pct exec 769276659 -- bash -lc "free -h && df -h"
```
### 5. Backup Strategy
#### Important Directories to Backup
```
/opt/customer-stack/volumes/postgres/data # Database data
/opt/customer-stack/volumes/n8n-data # n8n workflows and settings
/opt/customer-stack/.env # Environment configuration
/opt/customer-stack/workflow-template.json # Workflow template
```
#### Backup Commands
```bash
# Backup PostgreSQL
pct exec 769276659 -- bash -lc "docker exec customer-postgres pg_dump -U customer customer > /tmp/backup.sql"
# Backup n8n data
pct exec 769276659 -- bash -lc "tar -czf /tmp/n8n-backup.tar.gz /opt/customer-stack/volumes/n8n-data"
```
---
## Troubleshooting
### Container Won't Start
```bash
# Check container status
pct status 769276659
# Start container
pct start 769276659
# View container logs
pct exec 769276659 -- journalctl -xe
```
### Docker Services Not Running
```bash
# Check Docker status
pct exec 769276659 -- systemctl status docker
# Restart Docker
pct exec 769276659 -- systemctl restart docker
# Restart stack
pct exec 769276659 -- bash -lc "cd /opt/customer-stack && docker compose restart"
```
### n8n Not Accessible
```bash
# Check n8n container
pct exec 769276659 -- docker logs n8n
# Restart n8n
pct exec 769276659 -- bash -lc "cd /opt/customer-stack && docker compose restart n8n"
# Check port binding
pct exec 769276659 -- netstat -tlnp | grep 5678
```
### Database Connection Issues
```bash
# Test PostgreSQL
pct exec 769276659 -- docker exec customer-postgres pg_isready -U customer
# Check PostgreSQL logs
pct exec 769276659 -- docker logs customer-postgres
# Restart PostgreSQL
pct exec 769276659 -- bash -lc "cd /opt/customer-stack && docker compose restart postgres"
```
---
## Performance Optimization
### Recommended Settings
- **Memory:** 4GB is sufficient for moderate workloads
- **CPU:** 4 cores recommended for concurrent operations
- **Storage:** Monitor disk usage, especially for vector embeddings
### Monitoring Commands
```bash
# Container resource usage
pct exec 769276659 -- bash -lc "docker stats --no-stream"
# Database size
pct exec 769276659 -- bash -lc "docker exec customer-postgres psql -U customer -d customer -c 'SELECT pg_size_pretty(pg_database_size(current_database()));'"
# Document count
pct exec 769276659 -- bash -lc "docker exec customer-postgres psql -U customer -d customer -c 'SELECT COUNT(*) FROM documents;'"
```

# n8n Workflow Auto-Reload bei LXC-Neustart
## Übersicht
Diese Funktion sorgt dafür, dass der n8n-Workflow bei jedem Neustart des LXC-Containers automatisch neu geladen wird. Dies ist nützlich, um sicherzustellen, dass der Workflow immer im gewünschten Zustand ist, auch nach Updates oder Änderungen am Container.
## Funktionsweise
### Komponenten
1. **Systemd-Service** (`/etc/systemd/system/n8n-workflow-reload.service`)
- Wird beim LXC-Start automatisch ausgeführt
- Wartet auf Docker und n8n-Container
- Führt das Reload-Script aus
2. **Reload-Script** (`/opt/customer-stack/reload-workflow.sh`)
- Liest Konfiguration aus `.env`
- Wartet bis n8n API bereit ist
- Sucht nach bestehendem Workflow
- Löscht alten Workflow (falls vorhanden)
- Importiert Workflow aus Template
- Aktiviert den Workflow
- Loggt alle Aktionen
3. **Workflow-Template** (`/opt/customer-stack/workflow-template.json`)
- Persistente Kopie des Workflows
- Wird bei Installation erstellt
- Wird bei jedem Neustart verwendet
### Ablauf beim LXC-Neustart
```
LXC startet
↓
Docker startet
↓
n8n-Container startet
↓
Systemd-Service startet (nach 10s Verzögerung)
↓
Reload-Script wird ausgeführt
↓
1. Lade Konfiguration aus .env
2. Warte auf n8n API (max. 60s)
3. Login bei n8n
4. Suche nach bestehendem Workflow "RAG KI-Bot (PGVector)"
5. Lösche alten Workflow (falls vorhanden)
6. Suche nach Credentials (PostgreSQL, Ollama)
7. Verarbeite Workflow-Template (ersetze Credential-IDs)
8. Importiere neuen Workflow
9. Aktiviere Workflow
↓
Workflow ist bereit
```
## Installation
Die Auto-Reload-Funktion wird automatisch bei der Installation konfiguriert:
```bash
bash install.sh --debug
```
### Was wird installiert?
1. **Workflow-Template**: `/opt/customer-stack/workflow-template.json`
2. **Reload-Script**: `/opt/customer-stack/reload-workflow.sh`
3. **Systemd-Service**: `/etc/systemd/system/n8n-workflow-reload.service`
4. **Log-Verzeichnis**: `/opt/customer-stack/logs/`
## Logging
Alle Reload-Vorgänge werden geloggt:
- **Log-Datei**: `/opt/customer-stack/logs/workflow-reload.log`
- **Systemd-Journal**: `journalctl -u n8n-workflow-reload.service`
### Log-Beispiel

## Manuelles Testen
### Service-Status prüfen
```bash
# Im LXC-Container
systemctl status n8n-workflow-reload.service
```
### Manuelles Reload auslösen
```bash
# Im LXC-Container
/opt/customer-stack/reload-workflow.sh
```
### Logs anzeigen
```bash
# Log-Datei
cat /opt/customer-stack/logs/workflow-reload.log
# Systemd-Journal
journalctl -u n8n-workflow-reload.service -f
```
### Service neu starten
```bash
# Im LXC-Container
systemctl restart n8n-workflow-reload.service
```
## Fehlerbehandlung
### Häufige Probleme
1. **n8n API nicht erreichbar**
- Prüfen: `docker ps` - läuft n8n-Container?
- Prüfen: `curl http://127.0.0.1:5678/rest/settings`
- Lösung: Warten oder Docker-Container neu starten
2. **Login fehlgeschlagen**
- Prüfen: Sind die Credentials in `.env` korrekt?
- Prüfen: `cat /opt/customer-stack/.env`
- Lösung: Credentials korrigieren
3. **Credentials nicht gefunden**
- Prüfen: Existieren die Credentials in n8n?
- Lösung: Credentials manuell in n8n erstellen
4. **Workflow-Template nicht gefunden**
- Prüfen: `ls -la /opt/customer-stack/workflow-template.json`
- Lösung: Template aus Backup wiederherstellen
### Service deaktivieren
Falls Sie die Auto-Reload-Funktion deaktivieren möchten:
```bash
# Im LXC-Container
systemctl disable n8n-workflow-reload.service
systemctl stop n8n-workflow-reload.service
```
### Service wieder aktivieren
```bash
# Im LXC-Container
systemctl enable n8n-workflow-reload.service
systemctl start n8n-workflow-reload.service
```
## Technische Details
### Systemd-Service-Konfiguration
```ini
[Unit]
Description=n8n Workflow Auto-Reload Service
After=docker.service
Wants=docker.service
Requires=docker.service
[Service]
Type=oneshot
RemainAfterExit=yes
ExecStartPre=/bin/sleep 10
ExecStart=/bin/bash /opt/customer-stack/reload-workflow.sh
Restart=on-failure
RestartSec=30
[Install]
WantedBy=multi-user.target
```
### Workflow-Verarbeitung
Das Reload-Script verwendet Python, um das Workflow-Template zu verarbeiten:
1. Entfernt Felder: `id`, `versionId`, `meta`, `tags`, `active`, `pinData`
2. Ersetzt PostgreSQL Credential-IDs
3. Ersetzt Ollama Credential-IDs
4. Schreibt verarbeitetes JSON nach `/tmp/workflow_processed.json`
### API-Endpunkte
- **Login**: `POST /rest/login`
- **Workflows auflisten**: `GET /rest/workflows`
- **Workflow löschen**: `DELETE /rest/workflows/{id}`
- **Workflow importieren**: `POST /rest/workflows`
- **Workflow aktivieren**: `POST /rest/workflows/{id}/activate`
- **Credentials auflisten**: `GET /rest/credentials`
## Sicherheit
- Credentials werden aus `.env` gelesen (nicht im Script hardcoded)
- Session-Cookies werden nach Verwendung gelöscht
- Temporäre Dateien werden aufgeräumt
- Logs enthalten keine Passwörter
## Wartung
### Workflow-Template aktualisieren
Wenn Sie den Workflow ändern möchten:
1. Exportieren Sie den Workflow aus n8n UI
2. Kopieren Sie die JSON-Datei nach `/opt/customer-stack/workflow-template.json`
3. Beim nächsten Neustart wird der neue Workflow geladen
### Backup
Wichtige Dateien für Backup:
- `/opt/customer-stack/workflow-template.json`
- `/opt/customer-stack/.env`
- `/opt/customer-stack/logs/workflow-reload.log`
## Support
Bei Problemen:
1. Prüfen Sie die Logs: `/opt/customer-stack/logs/workflow-reload.log`
2. Prüfen Sie den Service-Status: `systemctl status n8n-workflow-reload.service`
3. Führen Sie das Script manuell aus: `/opt/customer-stack/reload-workflow.sh`
4. Prüfen Sie die n8n-Container-Logs: `docker logs n8n`

Usage:
bash install.sh [options]
Core options:
--ctid <id> Force CT ID (optional). If omitted, a customer-safe CTID is generated.
--cores <n> (default: unlimited)
--memory <mb> (default: 4096)
--swap <mb> (default: 512)
--disk <gb> (default: 50)
--bridge <vmbrX> (default: vmbr0)
--storage <storage> (default: local-zfs)
--ip <dhcp|CIDR> (default: dhcp)
--vlan <id> VLAN tag for net0 (default: 90; set 0 to disable)
--privileged Create privileged CT (default: unprivileged)
--apt-proxy <url> Optional: APT proxy (e.g. http://192.168.45.2:3142) for Apt-Cacher NG
Domain / n8n options:
--base-domain <domain> (default: userman.de) -> FQDN becomes sb-<unix>.domain
--n8n-owner-email <email> (default: admin@<base-domain>)
--n8n-owner-pass <pass> Optional. If omitted, generated (policy compliant).
--workflow-file <path> Path to n8n workflow JSON file (default: RAGKI-BotPGVector.json)
--ollama-model <model> Ollama chat model (default: ministral-3:3b)
--embedding-model <model> Ollama embedding model (default: nomic-embed-text:latest)
--debug Enable debug mode (show logs on stderr)
--help Show help
PostgREST / Supabase options:
--postgrest-port <port> PostgREST port (default: 3000)
Notes:
- This script creates a Debian 12 LXC and provisions Docker + customer stack (Postgres/pgvector + n8n + PostgREST).
- PostgREST provides a REST API for PostgreSQL, compatible with Supabase Vector Store node in n8n.
- At the end it prints a JSON with credentials and URLs.

## 🔧 Verwendung
### 1. Automatisches Speichern bei Installation
Credentials werden automatisch gespeichert:
```bash
# Installation durchführen
./install.sh --storage local-zfs --bridge vmbr0 --ip dhcp --vlan 90
# Credentials werden automatisch gespeichert
# credentials/sb-<timestamp>.json
```
### 2. Manuelles Speichern
Falls Sie Credentials manuell speichern möchten:
```bash
# JSON-Output in Datei speichern
./install.sh --storage local-zfs --bridge vmbr0 --ip dhcp --vlan 90 > output.json
# Mit save_credentials.sh speichern
./save_credentials.sh output.json
```
### 3. Credentials laden
```bash
# Credentials laden
CREDS=$(cat credentials/sb-1769276659.json)
# Einzelne Werte extrahieren
CTID=$(echo "$CREDS" | jq -r '.ctid')
IP=$(echo "$CREDS" | jq -r '.ip')
N8N_PASSWORD=$(echo "$CREDS" | jq -r '.n8n.owner_password')
```
## 🔄 Credentials aktualisieren
### Ollama-URL aktualisieren
Häufiger Use-Case: Ollama-URL von IP zu Hostname ändern
```bash
# Von IP zu Hostname
./update_credentials.sh \
--ctid 769276659 \
--ollama-url http://ollama.local:11434
# Mit Credentials-Datei
./update_credentials.sh \
--credentials credentials/sb-1769276659.json \
--ollama-url http://ollama.local:11434
```
### Ollama-Modell ändern
```bash
# Chat-Modell ändern
./update_credentials.sh \
--ctid 769276659 \
--ollama-model llama2:latest
# Embedding-Modell ändern
./update_credentials.sh \
--ctid 769276659 \
--embedding-model all-minilm:latest
# Beide gleichzeitig
./update_credentials.sh \
--ctid 769276659 \
--ollama-model llama2:latest \
--embedding-model all-minilm:latest
```
### Alle Optionen
```bash
./update_credentials.sh \

- Mindestens 14 Zeichen
- Groß- und Kleinbuchstaben
- Zahlen
- Keine Sonderzeichen (für bessere Kompatibilität)
## 🔄 Workflow
### Typischer Workflow
```bash
# 1. Installation
./install.sh --storage local-zfs --bridge vmbr0 --ip dhcp --vlan 90
# 2. Credentials werden automatisch gespeichert
# credentials/sb-<timestamp>.json
# 3. Später: Ollama-URL aktualisieren
./update_credentials.sh \
--credentials credentials/sb-*.json \
--ollama-url http://ollama.local:11434
# 4. Credentials für Automatisierung verwenden
CTID=$(jq -r '.ctid' credentials/sb-*.json)
IP=$(jq -r '.ip' credentials/sb-*.json)
```
### Automatisierung
```bash
#!/bin/bash

# FAQ - Häufig gestellte Fragen
Antworten auf häufig gestellte Fragen zum Customer Installer System.
## 🎯 Allgemein
### Was ist der Customer Installer?
Der Customer Installer ist ein automatisiertes Deployment-System für RAG (Retrieval-Augmented Generation) Stacks auf Proxmox VE. Es erstellt LXC-Container mit PostgreSQL, PostgREST, n8n und Ollama-Integration.
### Für wen ist das System gedacht?
- Entwickler, die schnell RAG-Systeme deployen möchten
- Unternehmen, die KI-Chatbots mit eigenem Wissen betreiben wollen
- Teams, die Workflow-Automation mit KI kombinieren möchten
### Welche Voraussetzungen gibt es?
- Proxmox VE Server (7.x oder 8.x)
- Root-Zugriff
- Netzwerk-Konfiguration (Bridge, optional VLAN)
- Optional: Ollama-Server für KI-Modelle
## 🚀 Installation
### Wie lange dauert die Installation?
Eine typische Installation dauert 5-10 Minuten, abhängig von:
- Netzwerk-Geschwindigkeit (Template-Download)
- Server-Performance
- APT-Proxy-Verfügbarkeit
### Kann ich mehrere Container installieren?
Ja! Jede Installation erstellt einen neuen Container mit eindeutiger CTID. Sie können beliebig viele Container parallel betreiben.
```bash
# Container 1
./install.sh --storage local-zfs --bridge vmbr0 --ip dhcp --vlan 90
# Container 2
./install.sh --storage local-zfs --bridge vmbr0 --ip dhcp --vlan 90
# Container 3
./install.sh --storage local-zfs --bridge vmbr0 --ip dhcp --vlan 90
```
### Wie funktioniert die CTID-Generierung?
Die CTID wird automatisch generiert basierend auf dem aktuellen Unix-Timestamp. Dies garantiert Eindeutigkeit für die nächsten 10 Jahre.
```bash
# Format: 7XXXXXXXXX (10 Stellen)
# Beispiel: 769276659
```
### Kann ich eine eigene CTID angeben?
Ja, mit dem `--ctid` Parameter:
```bash
./install.sh --ctid 100 --storage local-zfs --bridge vmbr0 --ip dhcp --vlan 90
```
**Achtung:** Stellen Sie sicher, dass die CTID nicht bereits verwendet wird!
## 🔧 Konfiguration
### Welche Ressourcen werden standardmäßig verwendet?
- **CPU:** Unlimited
- **RAM:** 4096 MB
- **Swap:** 512 MB

```bash
./update_credentials.sh \
--ctid 769276659 \
--ollama-url http://ollama.local:11434 \
--n8n-password "NewPassword123"
```
### Sind die Credentials sicher?
Ja:
- Gespeichert in `.gitignore`-geschütztem Verzeichnis
- Nicht im Git-Repository
- Nur auf dem Proxmox-Host zugänglich
- Passwörter werden automatisch generiert (14+ Zeichen)
### Wie kann ich das n8n-Passwort zurücksetzen?
```bash
