Presentation Outline: Self-Hosting n8n with Cloudflare Tunnels

1. Introduction

  • Brief introduction of self-hosting motivation
  • What & why n8n? (opensource, automation workflows, alternative to Zapier/IFTTT)
  • Overview of what will be shown:
    • Local setup (Docker Compose)
    • Exposing securely with Cloudflare Tunnel
    • Using private domain to access

2. Setup

  • Local machine
  • Network considerations: private LAN, DHCP/static IP setup
  • Security needs:
    • Avoid direct port forwarding
    • Use of Cloudflare Tunnel as safer alternative
  • Short explanation of n8n as an automation/orchestration tool
  • Why self-host instead of n8n.cloud? ***

3. Docker Compose Deployment

  • Folder structure (docker-compose.yml, .env file for secrets)
  • Key Compose services:
    • n8n container
    • Optional dependencies (Postgres for persistence)

4. Accessing and Securing n8n

  • Access workflow builder via s89n
  • Authentication via n8n built-in user management
  • Cloudflare Access (Zero Trust) as optional additional security:
    • Restricting access to certain emails/devices

5. Small Demo / Use Case

  • Webhook demo
  • Local model
  • Agent with tools
  • Agent with vision
  • Use deepseek locally
  • Robot picture
  • maybe ai dev team?

6. Closing \& Questions

  • Wrap-up:
    • n8n = flexible, open source, powerful automation platform
    • Self-hosting = more control, cheaper, but needs setup effort
    • Cloudflare Tunnel = simple, secure exposure without router headache
