Install and Run n8n on Raspberry Pi (Full Guide, Docker + Systemd)

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:

Home automation
Personal productivity workflows
IoT projects
Local-first, privacy-preserving integrations

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

Raspberry Pi OS 64-bit
Docker + Docker Compose
At least 2GB RAM recommended
Static local IP (optional but encouraged)

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

docker/ → holds Docker Compose file
data/ → persistent database + workflows

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]
    }
  ],
  "connections": {
    "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

Ensure systemd service points to the correct directory:
/home/pi/n8n/docker

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.
