+# BotKonzept Installer JSON API Documentation
+
+## Übersicht
+
+Diese API stellt die Installer-JSON-Daten sicher für Frontend-Clients bereit, **ohne Secrets preiszugeben**.
+
+**Basis-URL:** `http://192.168.45.104:3000` (PostgREST auf Kunden-LXC)  
+**Zentrale API:** `https://api.botkonzept.de` (zentrales PostgREST/n8n)
+
+---
+
+## Sicherheitsmodell
+
+### ✅ Erlaubte Daten (Frontend-sicher)
+
+- `ctid`, `hostname`, `fqdn`, `ip`, `vlan`
+- `urls.*` (alle URL-Endpunkte)
+- `supabase.url_external`
+- `supabase.anon_key`
+- `ollama.url`, `ollama.model`, `ollama.embedding_model`
+
+### ❌ Verbotene Daten (Secrets)
+
+- `postgres.password`
+- `supabase.service_role_key`
+- `supabase.jwt_secret`

+```
+
+**Authentifizierung:** Service Role Key erforderlich
+
+**CORS:** Nicht erlaubt (nur Backend-to-Backend)
+
+---
+
+### 5. Direct View Access (Authenticated)
+
+**Zweck:** Direkter Zugriff auf View (für authentifizierte Benutzer)
+
+**Route:** `GET /api/instance_config`
+
+**Request:**
+```bash
+curl -X GET 'http://192.168.45.104:3000/api/instance_config' \
+  -H "Authorization: Bearer <USER_JWT_TOKEN>"
+```
+
+**Response:** Array von Instanz-Konfigurationen (gefiltert nach RLS)
+
+**Authentifizierung:** JWT Token erforderlich (Supabase Auth)
+
+**CORS:** Erlaubt
+
+---
+
+## Authentifizierung
+
+### 1. Keine Authentifizierung (Public)
+
+- `/rpc/get_public_config`
+- `/rpc/get_instance_config_by_email` (sollte rate-limited sein)
+
+### 2. Service Role Key
+
+**Header:**
+```
+Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJyb2xlIjoic2VydmljZV9yb2xlIiwiaXNzIjoic3VwYWJhc2UiLCJpYXQiOjE3MDAwMDAwMDAsImV4cCI6MjAwMDAwMDAwMH0...
+```
+
+**Verwendung:**
+- `/rpc/get_instance_config_by_ctid`
+- `/rpc/store_installer_json`
+
+### 3. User JWT Token (Supabase Auth)
+
+**Header:**
+```
+Authorization: Bearer <USER_JWT_TOKEN>
+```
+
+**Verwendung:**
+- `/api/instance_config` (direkter View-Zugriff)
+
+---
+
+## CORS-Konfiguration
+
+### PostgREST CORS Headers
+
+In der PostgREST-Konfiguration (docker-compose.yml):
+
+```yaml
+postgrest:
+  environment:
+    PGRST_SERVER_CORS_ALLOWED_ORIGINS: "*"
+    # Oder spezifisch:
+    # PGRST_SERVER_CORS_ALLOWED_ORIGINS: "https://botkonzept.de,https://www.botkonzept.de"
+```
+
+### Nginx Reverse Proxy CORS
+
+Falls über Nginx:
+
+```nginx
+add_header 'Access-Control-Allow-Origin' '*';
+add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
+add_header 'Access-Control-Allow-Headers' 'Content-Type, Authorization';
+```
+
+---
+
+## Rate Limiting
+
+**Empfehlung:** Rate Limiting für öffentliche Endpunkte implementieren
+
+### Nginx Rate Limiting
+
+```nginx
+limit_req_zone $binary_remote_addr zone=api_limit:10m rate=10r/s;
+
+location /rpc/get_instance_config_by_email {
+    limit_req zone=api_limit burst=20 nodelay;
+    proxy_pass http://postgrest:3000;
+}
+```
+
+### PostgREST Rate Limiting
+
+Alternativ: Verwende einen API Gateway (Kong, Tyk) vor PostgREST.
+
+---
+
+## Fehlerbehandlung
+
+### HTTP Status Codes
+
+- `200 OK` - Erfolgreiche Anfrage
+- `204 No Content` - Keine Daten gefunden (PostgREST)
+- `400 Bad Request` - Ungültige Eingabe
+- `401 Unauthorized` - Fehlende/ungültige Authentifizierung
+- `403 Forbidden` - Keine Berechtigung
+- `404 Not Found` - Ressource nicht gefunden
+- `500 Internal Server Error` - Serverfehler
+
+### PostgREST Error Format
+
+```json
+{
+  "code": "PGRST301",
+  "message": "Invalid input syntax for type integer",
+  "details": "invalid input syntax for type integer: \"abc\"",
+  "hint": null
+}
+```
+
+---
+
+## Integration mit install.sh
+
+### Schritt 1: SQL-Schema anwenden
+
+```bash
+# Auf dem Proxmox Host
+pct exec <CTID> -- bash -c "
+  docker exec customer-postgres psql -U customer -d customer < /opt/customer-stack/sql/add_installer_json_api.sql
+"
+```
+
+### Schritt 2: install.sh erweitern
+
+Am Ende von `install.sh` (nach JSON-Generierung):
+
+```bash
+# Store installer JSON in database via PostgREST
+info "Storing installer JSON in database..."
+
+STORE_RESPONSE=$(curl -sS -X POST "http://${CT_IP}:${POSTGREST_PORT}/rpc/store_installer_json" \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer ${SERVICE_ROLE_KEY}" \
+  -d "{
+    \"customer_email_param\": \"${N8N_OWNER_EMAIL}\",
+    \"lxc_id_param\": ${CTID},
+    \"installer_json_param\": ${JSON_OUTPUT}
+  }" 2>&1)
+
+if echo "$STORE_RESPONSE" | grep -q '"success":true'; then
+  info "Installer JSON stored successfully"
+else
+  warn "Failed to store installer JSON: ${STORE_RESPONSE}"
+fi
+```
+
+---
+
+## Testing
+
+### Test 1: Public Config
+
+```bash
+curl -X POST 'http://192.168.45.104:3000/rpc/get_public_config' \
+  -H "Content-Type: application/json" \
+  -d '{}'
+
+# Erwartete Antwort:
+# {"registration_webhook_url":"https://api.botkonzept.de/webhook/botkonzept-registration","api_base_url":"https://api.botkonzept.de"}
+```
+
+### Test 2: Instance Config by Email
+
+```bash
+curl -X POST 'http://192.168.45.104:3000/rpc/get_instance_config_by_email' \
+  -H "Content-Type: application/json" \
+  -d '{"customer_email_param": "max@beispiel.de"}'
+
+# Erwartete Antwort: Array mit Instanz-Konfiguration (siehe oben)
+```
+
+### Test 3: Store Installer JSON (mit Service Role Key)
+
+```bash
+SERVICE_ROLE_KEY="eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."
+
+curl -X POST 'http://192.168.45.104:3000/rpc/store_installer_json' \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer ${SERVICE_ROLE_KEY}" \
+  -d '{
+    "customer_email_param": "max@beispiel.de",
+    "lxc_id_param": 769697636,
+    "installer_json_param": {"ctid": 769697636, "urls": {...}}
+  }'
+
+# Erwartete Antwort:
+# {"success":true,"instance_id":"...","customer_id":"...","message":"Installer JSON stored successfully"}
+```
+
+### Test 4: Verify No Secrets Exposed
+
+```bash
+curl -X POST 'http://192.168.45.104:3000/rpc/get_instance_config_by_email' \
+  -H "Content-Type: application/json" \
+  -d '{"customer_email_param": "max@beispiel.de"}' | jq .
+
+# Prüfe: Response enthält KEINE der folgenden Felder:
+# - postgres.password
+# - supabase.service_role_key
+# - supabase.jwt_secret
+# - n8n.owner_password
+# - n8n.encryption_key
+```
+
+---
+
+## Deployment Checklist
+
+- [ ] SQL-Schema auf allen Instanzen anwenden
+- [ ] PostgREST CORS konfigurieren
+- [ ] Rate Limiting aktivieren
+- [ ] install.sh erweitern (Installer JSON speichern)
+- [ ] Frontend auf neue API umstellen
+- [ ] Tests durchführen
+- [ ] Monitoring einrichten (API-Zugriffe loggen)
+
+---
+
+## Monitoring & Logging
+
+### Audit Log
+
+Alle API-Zugriffe werden in `audit_log` Tabelle protokolliert:
+
+```sql
+SELECT * FROM audit_log 
+WHERE action = 'api_config_access' 
+ORDER BY created_at DESC 
+LIMIT 10;
+```
+
+### PostgREST Logs
+
+```bash
+docker logs customer-postgrest --tail 100 -f
+```
+
+---
+
+## Sicherheitshinweise
+
+1. **Service Role Key schützen:** Niemals im Frontend verwenden!
+2. **Rate Limiting:** Öffentliche Endpunkte müssen rate-limited sein
+3. **HTTPS:** In Produktion nur über HTTPS (OPNsense Reverse Proxy)
+4. **Input Validation:** PostgREST validiert automatisch, aber zusätzliche Checks empfohlen
+5. **Audit Logging:** Alle API-Zugriffe werden geloggt
+

+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Automates provisioning of customer Proxmox LXC containers running a Docker stack (n8n + PostgreSQL/pgvector + PostgREST) with automatic OPNsense NGINX reverse proxy registration. Intended for a multi-tenant SaaS setup ("BotKonzept") where each customer gets an isolated container.
+
+## Key Commands
+
+```bash
+# Create a new customer LXC (must run on Proxmox host)
+bash install.sh --storage local-zfs --bridge vmbr0 --ip dhcp --vlan 90
+
+# With debug output (logs on stderr instead of only to file)
+DEBUG=1 bash install.sh --storage local-zfs --bridge vmbr0
+
+# With APT caching proxy
+bash install.sh --storage local-zfs --apt-proxy http://192.168.45.2:3142
+
+# Setup the BotKonzept management LXC (fixed CTID 5010)
+bash setup_botkonzept_lxc.sh
+
+# Delete an nginx proxy entry in OPNsense
+bash delete_nginx_proxy.sh --hostname sb-<unixts>
+```
+
+`install.sh` outputs a single JSON line to stdout with all credentials and URLs. Detailed logs go to `logs/<hostname>.log`. Credentials are saved to `credentials/<hostname>.json`.
+
+## Architecture
+
+### Script Dependency Tree
+
+```
+install.sh
+├── sources libsupabase.sh          (Proxmox helpers, logging, crypto, n8n setup)
+├── calls setup_nginx_proxy.sh      (OPNsense API integration)
+└── uses lib_installer_json_api.sh  (PostgREST DB storage - optional)
+
+setup_botkonzept_lxc.sh            (Standalone, for management LXC CTID 5010)
+```
+
+### Infrastructure Assumptions (hardcoded defaults)
+
+| Service | Address |
+|---|---|
+| OPNsense Firewall | `192.168.45.1:4444` |
+| Apt-Cacher NG | `192.168.45.2:3142` |
+| Docker Registry Mirror | `192.168.45.2:5000` |
+| Ollama API | `192.168.45.3:11434` |
+| Default VLAN | 90 |
+| Default storage | `local-zfs` |
+| Default base domain | `userman.de` |
+
+### What `install.sh` Does (Steps 5–11)
+
+1. **Step 5**: Creates and starts Proxmox LXC (Debian 12), waits for DHCP IP
+2. **Step 6**: Installs Docker CE + Compose plugin inside the CT
+3. **Step 7**: Generates secrets (PG password, JWT, n8n encryption key), writes `.env` and `docker-compose.yml` into CT, starts the stack
+4. **Step 8**: Creates n8n owner account via REST API
+5. **Step 10**: Imports and activates the RAG workflow via n8n API, sets up credentials (Postgres + Ollama)
+6. **Step 10a**: Installs a systemd service (`n8n-workflow-reload.service`) that re-imports and re-activates the workflow on every LXC restart
+7. **Step 11**: Registers an NGINX upstream/location in OPNsense via its REST API
+
+### Docker Stack Inside Each LXC (`/opt/customer-stack/`)
+
+- `postgres` – pgvector/pgvector:pg16, initialized from `sql/` directory
+- `postgrest` – PostgREST, exposes Supabase-compatible REST API on port 3000 (mapped to `POSTGREST_PORT`)
+- `n8n` – n8n automation, port 5678
+
+All three share a `customer-net` bridge network. The n8n instance connects to PostgREST via the Docker internal hostname `postgrest:3000` (not the external IP).
+
+### Key Files
+
+| File | Purpose |
+|---|---|
+| `libsupabase.sh` | Core library: logging (`info`/`warn`/`die`), Proxmox helpers (`pct_exec`, `pct_push_text`, `pve_*`), crypto (`gen_password_policy`, `gen_hex_64`), n8n setup (`n8n_setup_rag_workflow`) |
+| `setup_nginx_proxy.sh` | OPNsense API client; registers upstream + location for new CT |
+| `lib_installer_json_api.sh` | Stores installer JSON output into the BotKonzept Postgres DB via PostgREST |
+| `sql/botkonzept_schema.sql` | Customer management schema (customers, instances, emails, payments) for the BotKonzept management LXC |
+| `sql/init_pgvector.sql` | Inline in `install.sh`; creates pgvector extension, `documents` table, `match_documents` function, PostgREST roles |
+| `templates/reload-workflow.sh` | Runs inside customer LXC on every restart; logs to `/opt/customer-stack/logs/workflow-reload.log` |
+| `RAGKI-BotPGVector.json` | Default n8n workflow template (RAG KI-Bot with PGVector) |
+
+### Output and Logging
+
+- **Normal mode** (`DEBUG=0`): all script output goes to `logs/<hostname>.log`; only the final JSON is printed to stdout (via fd 3)
+- **Debug mode** (`DEBUG=1`): logs also written to stderr; JSON is formatted with `python3 -m json.tool`
+- Each customer container hostname is `sb-<unix_timestamp>`; CTID = unix_timestamp − 1,000,000,000
+
+### n8n Password Policy
+
+Passwords must be 8+ characters with at least 1 uppercase and 1 number. Enforced by `password_policy_check` in `libsupabase.sh`. Auto-generated passwords use `gen_password_policy`.
+
+### Workflow Auto-Reload
+
+On LXC restart, `n8n-workflow-reload.service` runs `reload-workflow.sh`, which:
+1. Waits for n8n API to be ready (up to 60s)
+2. Logs in with owner credentials from `.env`
+3. Deletes the existing "RAG KI-Bot (PGVector)" workflow
+4. Looks up existing Postgres and Ollama credential IDs
+5. Processes the workflow template (replaces credential IDs using Python)
+6. Imports and activates the new workflow

+# 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

+
+---
+
+## 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
+./update_credentials.sh --ctid 769276659 --ollama-url http://ollama.local:11434
+
+# 5. Verifizieren
+pct exec 769276659 -- docker exec n8n curl http://ollama.local:11434/api/tags
+
+# 6. Backup erstellen
+tar -czf credentials-backup-$(date +%Y%m%d).tar.gz credentials/
+```
+
+---
+
+## Zusammenfassung
+
+✅ **Credentials werden automatisch gespeichert**  
+✅ **Zentrale Verwaltung in JSON-Dateien**  
+✅ **Einfaches Update-System**  
+✅ **Sofortige Wirkung für Ollama-Änderungen**  
+✅ **Keine Container-Neustarts für Ollama-Updates**  
+✅ **Versionierung und Backup möglich**
+
+Das System ermöglicht flexible Credential-Verwaltung und macht es einfach, von IP-basierten zu Hostname-basierten Konfigurationen zu wechseln.

+# 🚀 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
+```
+

+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"**

+
+---
+
+### Schritt 4: Webhook-URL testen
+
+#### 4.1 Webhook-URL ermitteln
+
+Nach dem Import sollte die Webhook-URL sein:
+```
+https://n8n.userman.de/webhook/botkonzept-registration
+```
+
+**Prüfen Sie die URL:**
+1. Öffnen Sie den Workflow
+2. Klicken Sie auf den Node "Registration Webhook"
+3. Kopieren Sie die "Production URL"
+
+#### 4.2 Test mit curl
+
+```bash
+curl -X POST https://n8n.userman.de/webhook/botkonzept-registration \
+  -H "Content-Type: application/json" \
+  -d '{
+    "firstName": "Max",
+    "lastName": "Mustermann",
+    "email": "test@example.com",
+    "company": "Test GmbH",
+    "website": "https://example.com",
+    "newsletter": true
+  }'
+```
+
+**Erwartete Antwort:**
+```json
+{
+  "success": true,
+  "message": "Registrierung erfolgreich! Sie erhalten in Kürze eine E-Mail mit Ihren Zugangsdaten.",
+  "customerId": "uuid-hier",
+  "instanceUrl": "https://sb-XXXXX.userman.de"
+}
+```
+
+---
+
+## 🐛 Häufige Probleme & Lösungen
+
+### Problem 1: "Credential not found"
+
+**Lösung:**
+- Stellen Sie sicher, dass alle Credentials in n8n angelegt sind
+- 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)
+2. Schauen Sie in die Execution History (linke Sidebar → Executions)
+3. Prüfen Sie die Logs jedes Nodes
+
+---
+
+## 📊 Workflow-Ablauf im Detail

+---
+
+## 📈 Monitoring
+
+### n8n Executions überwachen
+
+```bash
+# In n8n UI
+Sidebar → Executions → Filter: "Failed"
+```
+
+### Datenbank-Queries
+
+```sql
+-- Neue Registrierungen heute
+SELECT COUNT(*) FROM customers WHERE DATE(created_at) = CURRENT_DATE;
+
+-- Aktive Trials
+SELECT COUNT(*) FROM customers WHERE status = 'trial';
+
+-- Versendete E-Mails heute
+SELECT email_type, COUNT(*) 
+FROM emails_sent 
+WHERE DATE(sent_at) = CURRENT_DATE 
+GROUP BY email_type;
+
+-- Trials die bald ablaufen
+SELECT * FROM trials_expiring_soon;
+```
+
+### Logs prüfen
+
+```bash
+# n8n Logs
+docker logs -f n8n
+
+# install.sh Logs
+ls -lh /root/customer-installer/logs/
+
+# Postfix Logs
+journalctl -u postfix -f
+```
+
+---
+
+## 🔐 Sicherheit
+
+### Wichtige Punkte
+
+1. **Credentials verschlüsseln**
+   - n8n verschlüsselt Credentials automatisch
+   - Encryption Key sichern: `N8N_ENCRYPTION_KEY`
+
+2. **SSH Keys schützen**
+   ```bash
+   chmod 600 ~/.ssh/id_ed25519
+   ```
+
+3. **Datenbank-Zugriff**
+   - Verwenden Sie `service_role` Key für n8n
+   - Niemals `anon` Key für Backend-Operationen
+
+4. **E-Mail-Sicherheit**
+   - SPF, DKIM, DMARC konfigurieren
+   - Absender-Domain verifizieren

+- Timeout-Fehler
+
+### Diagnose
+```bash
+# 1. Prüfen ob n8n läuft
+curl -I https://n8n.userman.de
+
+# 2. Webhook-URL testen
+curl -X POST https://n8n.userman.de/webhook/botkonzept-registration \
+  -H "Content-Type: application/json" \
+  -d '{"firstName":"Test","lastName":"User","email":"test@test.de"}'
+```
+
+### Lösungen
+
+#### A) Workflow nicht aktiviert
+1. Öffnen Sie n8n
+2. Öffnen Sie den Workflow
+3. Klicken Sie auf den **Toggle oben rechts** (muss grün sein)
+4. Speichern Sie den Workflow
+
+#### B) Webhook-Pfad falsch
+1. Öffnen Sie den Workflow
+2. Klicken Sie auf "Registration Webhook" Node
+3. Prüfen Sie den Pfad: Sollte `botkonzept-registration` sein
+4. Kopieren Sie die "Production URL"
+5. Aktualisieren Sie `customer-frontend/js/main.js`:
+```javascript
+const CONFIG = {
+    WEBHOOK_URL: 'https://n8n.userman.de/webhook/botkonzept-registration',
+    // ...
+};
+```
+
+#### C) n8n nicht erreichbar
+```bash
+# Auf dem n8n Server
+docker ps | grep n8n
+docker logs n8n
+
+# Falls Container nicht läuft
+docker start n8n
+```
+
+---
+
+## 🚨 Problem 2: "Credential not found" Fehler
+
+### Symptome
+- Workflow stoppt bei einem Node
+- Fehler: "Credential 'Supabase Local' not found"
+- Execution zeigt roten Fehler
+
+### Lösung
+
+#### Schritt 1: Credentials prüfen
+1. n8n → Sidebar → **Credentials**
+2. Prüfen Sie ob folgende existieren:
+   - `Supabase Local` (Postgres)
+   - `PVE20` (SSH)
+   - `Postfix SES` (SMTP)
+
+#### Schritt 2: Credential erstellen (falls fehlend)
+
+**Supabase Local:**
+```
+Name: Supabase Local
+Type: Postgres
+Host: localhost (oder Ihr Supabase Host)
+Port: 5432
+Database: botkonzept
+User: postgres
+Password: [Ihr Passwort]
+SSL: Enabled
+```
+
+**PVE20:**
+```
+Name: PVE20
+Type: SSH (Private Key)
+Host: 192.168.45.20
+Port: 22
+Username: root
+Private Key: [Fügen Sie Ihren Private Key ein]
+```
+
+**Postfix SES:**
+```
+Name: Postfix SES
+Type: SMTP
+Host: email-smtp.eu-central-1.amazonaws.com
+Port: 587
+User: [SMTP Username]
+Password: [SMTP Password]
+From: noreply@botkonzept.de
+```
+
+#### Schritt 3: Credential im Workflow zuweisen
+1. Öffnen Sie den betroffenen Node
+2. Klicken Sie auf "Credential to connect with"
+3. Wählen Sie das richtige Credential
+4. Speichern Sie den Workflow
+
+---
+
+## 🚨 Problem 3: SSH-Verbindung zu PVE20 schlägt fehl
+
+### Symptome
+- Node "Create Customer Instance" schlägt fehl
+- Fehler: "Connection refused" oder "Permission denied"
+
+### Diagnose
+```bash
+# Auf dem n8n Server (im Container)
+docker exec -it n8n sh
+
+# SSH-Verbindung testen
+ssh root@192.168.45.20 "echo 'Connection OK'"
+```
+
+### Lösungen
+
+#### A) SSH Key nicht konfiguriert
+```bash
+# Auf dem n8n Server (Host, nicht Container)
+ssh-keygen -t ed25519 -C "n8n@botkonzept" -f ~/.ssh/n8n_key
+
+# Public Key auf PVE20 kopieren
+ssh-copy-id -i ~/.ssh/n8n_key.pub root@192.168.45.20
+
+# Private Key anzeigen (für n8n Credential)
+cat ~/.ssh/n8n_key
+```
+
+#### B) SSH Key im Container nicht verfügbar
+```bash
+# SSH Key als Volume mounten
+docker run -d \
+  --name n8n \
+  -v ~/.ssh:/home/node/.ssh:ro \
+  -v n8n_data:/home/node/.n8n \
+  -p 5678:5678 \
+  n8nio/n8n
+```
+
+#### C) Firewall blockiert
+```bash
+# Auf PVE20
+iptables -L -n | grep 22
+
+# Falls blockiert, Regel hinzufügen
+iptables -A INPUT -p tcp --dport 22 -j ACCEPT
+```
+
+---
+
+## 🚨 Problem 4: install.sh schlägt fehl
+
+### Symptome
+- SSH-Verbindung OK, aber install.sh gibt Fehler
+- Fehler: "No such file or directory"
+- Fehler: "Permission denied"
+
+### Diagnose
+```bash
+# Auf PVE20
+ls -lh /root/customer-installer/install.sh
+
+# Ausführbar?
+chmod +x /root/customer-installer/install.sh
+
+# Manuell testen
+cd /root/customer-installer
+./install.sh --help
+```
+
+### Lösungen
+
+#### A) Repository nicht geklont
+```bash
+# Auf PVE20
+cd /root
+git clone https://backoffice.userman.de/MediaMetz/customer-installer.git
+cd customer-installer
+chmod +x install.sh
+```
+
+#### B) Pfad im Workflow falsch
+1. Öffnen Sie den Node "Create Customer Instance"
+2. Prüfen Sie den Command:
+```bash
+/root/customer-installer/install.sh --storage local-zfs ...
+```
+3. Passen Sie den Pfad an falls nötig
+
+#### C) Abhängigkeiten fehlen
+```bash
+# Auf PVE20
+apt-get update
+apt-get install -y jq curl python3
+```
+
+---
+
+## 🚨 Problem 5: Datenbank-Fehler
+
+### Symptome
+- Fehler: "relation 'customers' does not exist"
+- Fehler: "permission denied for table customers"
+- Fehler: "connection refused"
+
+### Diagnose
+```bash
+# Verbindung testen
+psql -h localhost -U postgres -d botkonzept -c "SELECT 1;"
+
+# Tabellen prüfen
+psql -h localhost -U postgres -d botkonzept -c "\dt"
+```
+
+### Lösungen
+
+#### A) Schema nicht erstellt
+```bash
+# Schema erstellen
+psql -U postgres -d botkonzept < /root/customer-installer/sql/botkonzept_schema.sql
+
+# Prüfen
+psql -U postgres -d botkonzept -c "\dt"
+```
+
+#### B) Datenbank existiert nicht
+```bash
+# Datenbank erstellen
+createdb -U postgres botkonzept
+
+# Schema importieren
+psql -U postgres -d botkonzept < /root/customer-installer/sql/botkonzept_schema.sql
+```
+
+#### C) Berechtigungen fehlen
+```sql
+-- Als postgres User
+GRANT ALL ON ALL TABLES IN SCHEMA public TO service_role;
+GRANT ALL ON ALL SEQUENCES IN SCHEMA public TO service_role;
+```
+
+#### D) Supabase: Falsche Credentials
+1. Gehen Sie zu Supabase Dashboard
+2. Settings → Database
+3. Kopieren Sie die Connection String
+4. Aktualisieren Sie das n8n Credential
+
+---
+
+## 🚨 Problem 6: E-Mail wird nicht versendet
+
+### Symptome
+- Workflow läuft durch, aber keine E-Mail
+- Fehler: "SMTP connection failed"
+- E-Mail landet im Spam
+
+### Diagnose
+```bash
+# SMTP-Verbindung testen
+telnet email-smtp.eu-central-1.amazonaws.com 587
+
+# Postfix Status (falls lokal)
+systemctl status postfix
+journalctl -u postfix -n 50
+```
+
+### Lösungen
+
+#### A) Amazon SES: E-Mail nicht verifiziert
+1. Gehen Sie zu AWS SES Console
+2. Verified Identities → Verify new email
+3. Bestätigen Sie die E-Mail
+4. Warten Sie auf Verifizierung
+
+#### B) Amazon SES: Sandbox-Modus
+1. AWS SES Console → Account Dashboard
+2. Request production access
+3. Füllen Sie das Formular aus
+4. Warten Sie auf Genehmigung (24-48h)
+
+**Workaround für Tests:**
+- Verifizieren Sie auch die Empfänger-E-Mail
+- Oder verwenden Sie Gmail für Tests
+
+#### C) SMTP-Credentials falsch
+1. AWS IAM → Users → Ihr SMTP User
+2. Security Credentials → Create SMTP credentials
+3. Kopieren Sie Username und Password
+4. Aktualisieren Sie n8n SMTP Credential
+
+#### D) SPF/DKIM nicht konfiguriert
+```bash
+# DNS-Records prüfen
+dig TXT botkonzept.de
+dig TXT _dmarc.botkonzept.de
+
+# Fehlende Records hinzufügen (bei Ihrem DNS-Provider)
+```
+
+**Benötigte DNS-Records:**
+```
+# 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');
+```

+
+## Deployment-Schritte
+
+### Schritt 1: SQL-Schema anwenden
+
+```bash
+# Auf bestehendem Container
+CTID=769697636
+
+pct exec ${CTID} -- bash -c "
+  docker exec customer-postgres psql -U customer -d customer < /opt/customer-stack/sql/add_installer_json_api.sql
+"
+```
+
+### Schritt 2: Test ausführen
+
+```bash
+# Basis-Test
+bash customer-installer/test_installer_json_api.sh \
+  --postgrest-url http://192.168.45.104:3000
+
+# Mit Service Role Key
+bash customer-installer/test_installer_json_api.sh \
+  --postgrest-url http://192.168.45.104:3000 \
+  --service-role-key "eyJhbGc..."
+```
+
+### Schritt 3: install.sh erweitern (nächster Schritt)
+
+Am Ende von `install.sh` hinzufügen:
+
+```bash
+# Source API library
+source "${SCRIPT_DIR}/lib_installer_json_api.sh"
+
+# Apply SQL schema
+apply_installer_json_api_schema "${CTID}"
+
+# Store installer JSON in database
+store_installer_json_in_db \
+  "${CTID}" \
+  "${N8N_OWNER_EMAIL}" \
+  "${SUPABASE_URL_EXTERNAL}" \
+  "${SERVICE_ROLE_KEY}" \
+  "${JSON_OUTPUT}"
+
+# Verify storage
+verify_installer_json_stored \
+  "${CTID}" \
+  "${N8N_OWNER_EMAIL}" \
+  "${SUPABASE_URL_EXTERNAL}"
+```
+
+---
+
+## Curl-Tests
+
+### Test 1: Public Config
+
+```bash
+curl -X POST 'http://192.168.45.104:3000/rpc/get_public_config' \
+  -H "Content-Type: application/json" \
+  -d '{}'
+
+# Erwartete Antwort:
+# {"registration_webhook_url":"https://api.botkonzept.de/webhook/botkonzept-registration","api_base_url":"https://api.botkonzept.de"}
+```
+
+### Test 2: Instance Config by Email
+
+```bash
+curl -X POST 'http://192.168.45.104:3000/rpc/get_instance_config_by_email' \
+  -H "Content-Type: application/json" \
+  -d '{"customer_email_param": "max@beispiel.de"}'
+
+# Erwartete Antwort: Array mit Instanz-Config (siehe oben)
+```
+
+### Test 3: Verify No Secrets
+
+```bash
+curl -X POST 'http://192.168.45.104:3000/rpc/get_instance_config_by_email' \
+  -H "Content-Type: application/json" \
+  -d '{"customer_email_param": "max@beispiel.de"}' | jq .
+
+# Prüfe: Response enthält KEINE der folgenden Strings:
+# - "password"
+# - "service_role_key"
+# - "jwt_secret"
+# - "encryption_key"
+# - "owner_password"
+```
+
+### Test 4: Store Installer JSON (mit Service Role Key)
+
+```bash
+SERVICE_ROLE_KEY="eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."
+
+curl -X POST 'http://192.168.45.104:3000/rpc/store_installer_json' \

+    }
+  }'
+
+# Erwartete Antwort:
+# {"success":true,"instance_id":"...","customer_id":"...","message":"Installer JSON stored successfully"}
+```
+

+```
+
+**⚠️ IMPORTANT:** Store these credentials securely. They are also available in:
+- Installation JSON output
+- Container: `/opt/customer-stack/.env`
+- Log file: `logs/sb-1769276659.log`
+
+---
+
+## 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

+# 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`

+```
+
+## 🔧 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 \
+  --ctid 769276659 \
+  --ollama-url http://ollama.local:11434 \
+  --ollama-model llama2:latest \
+  --embedding-model all-minilm:latest \
+  --n8n-email admin@userman.de \
+  --n8n-password "NewPassword123"
+```
+
+## 📝 update_credentials.sh Optionen
+
+| Parameter | Beschreibung | Beispiel |
+|-----------|--------------|----------|
+| `--ctid <id>` | Container-ID | `--ctid 769276659` |
+| `--credentials <file>` | Credentials-Datei | `--credentials credentials/sb-*.json` |
+| `--ollama-url <url>` | Ollama Server URL | `--ollama-url http://ollama.local:11434` |
+| `--ollama-model <model>` | Chat-Modell | `--ollama-model llama2:latest` |
+| `--embedding-model <model>` | Embedding-Modell | `--embedding-model all-minilm:latest` |

+| `--n8n-password <pass>` | n8n Admin-Passwort | `--n8n-password "NewPass123"` |
+
+## 🔐 Sicherheit
+
+### Git-Schutz
+
+Credentials werden automatisch von Git ausgeschlossen:
+
+```bash
+# credentials/.gitignore
+*.json
+!example-credentials.json
+```
+
+### Berechtigungen
+
+```bash
+# Credentials-Verzeichnis schützen
+chmod 700 credentials/
+chmod 600 credentials/*.json
+```
+
+### Passwort-Richtlinien
+
+Automatisch generierte Passwörter erfüllen:
+- 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
+- **Disk:** 50 GB
+- **Netzwerk:** DHCP, VLAN 90
+
+### Kann ich die Ressourcen anpassen?
+
+Ja, alle Ressourcen sind konfigurierbar:
+
+```bash
+./install.sh \
+  --cores 4 \
+  --memory 8192 \
+  --swap 1024 \
+  --disk 100 \
+  --storage local-zfs \
+  --bridge vmbr0 \
+  --ip dhcp \
+  --vlan 90
+```
+
+### Wie verwende ich eine statische IP?
+
+```bash
+./install.sh \
+  --storage local-zfs \
+  --bridge vmbr0 \
+  --ip 192.168.45.100/24 \
+  --vlan 90
+```
+
+### Kann ich VLAN deaktivieren?
+
+Ja, setzen Sie `--vlan 0`:
+
+```bash
+./install.sh --storage local-zfs --bridge vmbr0 --ip dhcp --vlan 0
+```
+
+## 🔐 Credentials
+
+### Wo werden die Credentials gespeichert?
+
+Automatisch in `credentials/sb-<timestamp>.json` nach erfolgreicher Installation.
+
+### Wie kann ich Credentials später ändern?
+
+Mit dem `update_credentials.sh` Script:
+
+```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
+pct exec <ctid> -- docker exec n8n \
+  n8n user-management:reset \
+  --email=admin@userman.de \
+  --password=NewPassword123
+```
+
+## 🐳 Docker & Container
+
+### Welche Docker-Container werden erstellt?

+1. **customer-postgres** - PostgreSQL 16 mit pgvector
+2. **customer-postgrest** - PostgREST API
+3. **n8n** - Workflow-Automation
+
+### Wie kann ich in einen Container einloggen?
+
+```bash
+# In LXC-Container
+pct enter <ctid>
+
+# In Docker-Container
+pct exec <ctid> -- docker exec -it n8n sh
+pct exec <ctid> -- docker exec -it customer-postgres bash
+```
+
+### Wie starte ich Container neu?
+
+```bash
+# Einzelner Docker-Container
+pct exec <ctid> -- docker compose -f /opt/customer-stack/docker-compose.yml restart n8n
+
+# Alle Docker-Container
+pct exec <ctid> -- docker compose -f /opt/customer-stack/docker-compose.yml restart
+
+# LXC-Container
+pct restart <ctid>
+```
+
+### Wie stoppe ich Container?
+
+```bash
+# Docker-Container stoppen
+pct exec <ctid> -- docker compose -f /opt/customer-stack/docker-compose.yml down
+
+# LXC-Container stoppen
+pct stop <ctid>
+```
+
+## 📊 Datenbank
+
+### Welche PostgreSQL-Version wird verwendet?
+
+PostgreSQL 16 (Alpine-basiert)
+
+### Ist pgvector installiert?
+

+```bash
+# Via Docker
+pct exec <ctid> -- docker exec -it customer-postgres \
+  psql -U customer -d customer
+
+# Credentials aus Datei
+cat credentials/sb-*.json | jq -r '.postgres'
+```
+
+### Wie groß ist die Embedding-Dimension?
+
+384 Dimensionen (für nomic-embed-text Modell)
+
+### Kann ich die Dimension ändern?
+
+Ja, aber Sie müssen:
+1. Tabelle neu erstellen
+2. Anderes Embedding-Modell verwenden
+3. Alle Dokumente neu embedden
+
+```sql
+-- Neue Dimension (z.B. 768 für andere Modelle)
+CREATE TABLE documents (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  content TEXT NOT NULL,
+  metadata JSONB,
+  embedding vector(768),  -- Geänderte Dimension
+  created_at TIMESTAMPTZ DEFAULT NOW()
+);
+```
