n8n Queue Mode

A production-ready n8n stack configured for queue mode, enabling horizontal scaling of workflow executions. PostgreSQL 16 serves as the primary data store for workflows, credentials, and execution history, while Redis acts as the message broker for distributing work across n8n worker processes. The main n8n instance handles the web editor and webhook triggers, while the worker service processes queued executions independently. This architecture is ideal for high-volume automation scenarios where a single n8n instance would bottleneck on long-running workflows. All services include health checks, resource limits, and named volumes for data durability across restarts.

Wann verwenden

Dieses Template ist ideal für die Einrichtung einer n8n queue mode Umgebung. Alle Services sind mit Healthchecks, Ressourcenlimits und sinnvollen Standardwerten vorkonfiguriert. Passen Sie die Umgebungsvariablen an, bevor Sie in Produktion gehen.

Tipps

Ändern Sie alle Standardpasswörter vor dem Deployment
Überprüfen Sie die Ressourcenlimits für Ihre Hardware
Fügen Sie einen Reverse Proxy für HTTPS in Produktion hinzu
Konfigurieren Sie Backup-Strategien für Daten-Volumes
