Installation

1. Copy and edit environment file:

cp .env.example .env
nano .env

2. Set required secrets (use openssl rand -hex 32 to generate):

N8N_ENCRYPTION_KEY=
N8N_USER_MANAGEMENT_JWT_SECRET=
POSTGRES_PASSWORD=
JWT_SECRET=
ANON_KEY=
SERVICE_ROLE_KEY=
DASHBOARD_USERNAME=
DASHBOARD_PASSWORD=
NEO4J_AUTH=neo4j/yourpassword
CLICKHOUSE_PASSWORD=
MINIO_ROOT_PASSWORD=
LANGFUSE_SALT=
NEXTAUTH_SECRET=
ENCRYPTION_KEY=

Usage

Start all services:

./run.sh

Enable/disable specific services by editing the configuration at the top of run.sh:

ENABLE_SUPABASE=true
ENABLE_N8N=true
ENABLE_OPENWEBUI=true
ENABLE_FLOWISE=true
ENABLE_QDRANT=true
ENABLE_NEO4J=true
ENABLE_LANGFUSE=true
ENABLE_PORTAINER=true

Set any service to false to disable it.

WARNING: All ports are exposed on 0.0.0.0. Only use in trusted environments.

Service Access

Main services:

• Supabase: http://localhost:8000
• n8n: http://localhost:5678
• Open WebUI: http://localhost:8080
• Flowise: http://localhost:3001
• Qdrant: http://localhost:6333
• Neo4j: http://localhost:7474
• Langfuse: http://localhost:3000
  • ClickHouse: http://localhost:8123 (HTTP), localhost:9000 (native)
  • MinIO Console: http://localhost:9011
  • PostgreSQL: localhost:5433
  • Redis: localhost:6379
• Portainer: http://localhost:9123

First access to n8n and Open WebUI requires local account setup.

Service Connection Info

For n8n workflows:

• Postgres host: db
• Qdrant: http://qdrant:6333

n8n + Open WebUI Integration

1. Create n8n workflow with webhook trigger
2. Copy production webhook URL
3. Open WebUI: Workspace -> Functions -> Add Function
4. Paste code from n8n_pipe.py
5. Set n8n_url to webhook URL
6. Enable function

Upgrading

./run.sh

The run.sh script stops, pulls latest versions, and restarts all enabled services.

Local File Access

n8n can access files in ./shared directory at container path /data/shared

Troubleshooting

Common issues:

• Supabase pooler restarting: Check supabase/supabase#30210
• Supabase analytics fails after password change: Delete supabase/docker/volumes/db/data
• Docker Desktop: Enable "Expose daemon on tcp://localhost:2375 without TLS"
• Supabase connection fails: No "@" in POSTGRES_PASSWORD
• SearXNG restarting: Run chmod 755 searxng
• Missing Supabase files: Delete supabase/ folder and restart
