Production Engineering Guide

Engineering Guide: Running n8n AI Workflow Automation + Queue Workers on Netcup Infrastructure

Recommended kernel parameters, memory management, and security hardening for maximum reliability.

1

Memory Management & Swappiness

Add a 4–8 GB swapfile and set "sysctl vm.swappiness=10" to prevent the Linux OOM Killer from terminating container processes during memory allocation spikes.

2

SMTP Port 25 for Alerts

If your app sends notification emails: delete the "netcup Mail block" rule in SCP Firewall and configure a clean reverse DNS (rDNS/PTR) record matching your domain.

3

Persistent Storage & Offsite Backups

Mount application state into named Docker volumes. Automate daily offsite backups using BorgBackup or Restic — remember SCP snapshots expire automatically after 30 days.

4

Firewall & SSH Port Hardening

Keep UFW active allowing only ports 80 and 443 publicly. Shift SSH from port 22 to a custom high port to eliminate automated credential stuffing scan noise.
