n8n Automation

A self-hosted n8n automation stack with PostgreSQL 16 as the persistence layer for workflows, credentials, and execution history. n8n is configured with basic authentication and exposes its web editor on port 5678, while PostgreSQL stores all data in a named volume for durability. The stack supports webhook URLs, timezone configuration, and execution pruning out of the box. Both services run on an internal backend network with health checks and resource limits to ensure stable long-running operation. Simply set the environment variables and access the n8n editor to start building automation workflows.

Quando Usarlo

Questo template è ideale per configurare un ambiente n8n automation Tutti i servizi sono preconfigurati con healthchecks, limiti di risorse e valori predefiniti sensati. Personalizza le variabili d'ambiente prima di fare il deploy in produzione.

Consigli

Cambia tutte le password predefinite prima del deploy
Verifica i limiti di risorse per il tuo hardware
Aggiungi un reverse proxy per HTTPS in produzione
Configura strategie di backup per i volumi di dati
