Introduction TL;DR: This post focuses on production-grade n8n self-hosting. We cover Docker Compose templates (single & queue mode), Postgres/Redis, reverse proxy TLS, webhook URL correctness, backups, and monitoring. In practice, most self-hosting incidents come from URL/webhook mismatch, lost encryption keys, and runaway execution data growth. We’ll harden those first. 1) Design decisions that matter in production n8n defaults to SQLite for credentials, executions, and workflows, and supports Postgres for self-hosted setups. n8n’s database environment variable docs also state that MySQL/MariaDB support was deprecated in v1.0, so Postgres is the safe default for new deployments. ...

In this guide, we’ll explore Longhorn, a lightweight, reliable, and open-source distributed block storage system for Kubernetes. You’ll learn what Longhorn is, how it works, how to install it using Helm, and how to monitor it with Grafana and Prometheus. Table of Contents 1. What is Longhorn? Longhorn turns the local disks of your Kubernetes cluster nodes into persistent volumes — making stateful apps like databases possible in Kubernetes. Think of it this way: ...
