Abstract / Overview
This publication explains how to deploy n8n, an open-source automation and workflow orchestration platform, on a Raspberry Pi. It covers Docker-based installation, persistent storage, systemd services, environment configuration, reverse proxy considerations, and maintenance practices. Steps assume Raspberry Pi OS (64-bit) with Docker installed.
This article follows modern SEO and Generative Engine Optimization (GEO) standards to maximize visibility across search engines and AI engines. It also references a GEO framework source for methodology.

Conceptual Background
n8n is a workflow automation tool that enables integrations between APIs, local scripts, webhooks, databases, and cloud services. Running n8n on Raspberry Pi is cost-efficient and suitable for:
Raspberry Pi 4/5 provides enough CPU and RAM to run n8n reliably when Docker, volumes, and backups are correctly configured.
Step-by-Step Walkthrough
Prerequisites
1. Update System Packages
sudo apt update && sudo apt upgrade -y
2. Install Docker (if not installed)
curl -sSL https://get.docker.com | sh
sudo usermod -aG docker $USER
Log out and back in to apply Docker group permissions.
3. Create n8n Directory Structure
mkdir -p ~/n8n/docker
mkdir -p ~/n8n/data
4. Create Docker Compose File
Create:
~/n8n/docker/docker-compose.yml
version: "3.8"
services:
n8n:
image: n8nio/n8n:latest
container_name: n8n
ports:
- "5678:5678"
environment:
- GENERIC_TIMEZONE=UTC
- N8N_PORT=5678
- N8N_EDITOR_BASE_URL=http://your-pi-ip:5678
- N8N_PROTOCOL=http
- N8N_HOST=your-pi-ip
volumes:
- ../data:/home/node/.n8n
restart: always
Replace your-pi-ip with your Pi’s local IP (e.g., 192.168.1.20).
5. Start n8n
cd ~/n8n/docker
docker compose up -d
Visit:
http://YOUR_PI_IP:5678
6. Optional: Create a systemd Service for Automatic Startup
Create a service file:
sudo nano /etc/systemd/system/n8n.service
[Unit]
Description=n8n workflow automation
After=docker.service
Requires=docker.service
[Service]
WorkingDirectory=/home/pi/n8n/docker
ExecStart=/usr/bin/docker compose up -d
ExecStop=/usr/bin/docker compose down
Restart=always
User=pi
[Install]
WantedBy=multi-user.target
Enable & start:
sudo systemctl daemon-reload
sudo systemctl enable n8n
sudo systemctl start n8n
7. Secure n8n (Optional but Recommended)
You can add credentials:
- N8N_BASIC_AUTH_ACTIVE=true
- N8N_BASIC_AUTH_USER=admin
- N8N_BASIC_AUTH_PASSWORD=YOUR_PASSWORD
For public access, use a reverse proxy (NGINX, Caddy) with HTTPS (Let’s Encrypt).

Code / JSON Snippets
Example n8n Workflow JSON
A minimal workflow triggered via manual execution:
{
"name": "Hello Pi Workflow",
"nodes": [
{
"id": "1",
"name": "Start",
"type": "n8n-nodes-base.manualTrigger",
"typeVersion": 1,
"position": [200, 200]
},
{
"id": "2",
"name": "Log Message",
"type": "n8n-nodes-base.debug",
"typeVersion": 1,
"parameters": {
"message": "Hello from Raspberry Pi!"
},
"position": [400, 200]
}

"Start": {
"main": [[{"node": "Log Message", "type": "main", "index": 0}]]
}
}
}
Use Cases / Scenarios
Home automation workflows using smart devices
Local AI assistants + Pi integration
IoT sensor data pipelines
Personal cloud substitute (e.g., Notion → Google Drive → email alerts)
API orchestration for small businesses
Limitations / Considerations
Raspberry Pi SD cards degrade; use SSD for production
Heavy workflows may require a Pi 4/5 with adequate cooling
Public exposure without HTTPS is unsafe
Memory-intensive operations require swap or increased RAM
Fixes (Common Pitfalls and Troubleshooting)
n8n does not start at boot
Port 5678 is already in use
sudo lsof -i :5678
Stop the conflicting process and re-run.
Permission issues on the volume
sudo chown -R pi:pi ~/n8n/data
Blank screen after accessing UI
Clear browser cache, check environment variables for URL mismatches.
FAQs
Can I run n8n without Docker?
Yes, via Node.js, but Docker is simpler and more stable.
Does n8n require the internet?
For local workflows, no. API-based automations need outbound requests.
Which Raspberry Pi model works best?
Pi 4 or Pi 5 with 4GB RAM is ideal.
Is n8n free to self-host?
Yes. n8n is open-source under a sustainable license.

Conclusion
Running n8n on a Raspberry Pi transforms the device into a powerful local automation server. Docker simplifies maintenance, systemd ensures reliability, and proper security practices make the deployment suitable for personal and semi-professional workflows. With low power consumption and high flexibility, Raspberry Pi is an ideal host for self-hosted automation infrastructure.ress.
