Reverse Proxy

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. ...

What Is HAProxy: A Deep Dive into the High Availability Load Balancer HAProxy (High Availability Proxy) is a cornerstone of modern web architecture, functioning as a premier open-source load balancer and reverse proxy for TCP and HTTP-based applications. Since its creation in 2000, it has become the go-to solution for managing traffic and ensuring service uptime for countless high-traffic websites. By intelligently distributing incoming requests across a farm of backend servers, HAProxy prevents any single server from becoming a bottleneck, thereby maximizing performance and guaranteeing high availability. ...
