Whether you’re an indie developer, a startup, or an automation enthusiast, DigitalOcean’s droplets (virtual servers) provide a perfect balance between performance and price.

In this comprehensive guide, we will take you from zero to a fully functional n8n deployment on DigitalOcean. You’ll learn how to set up a droplet, install Docker and n8n, configure environment variables, secure your instance with HTTPS, and keep it updated. No matter your experience level, this step-by-step tutorial will empower you to create your own automation platform.

Prerequisites

Before you start deploying n8n, it’s essential to ensure you have the right tools and knowledge ready. This prevents roadblocks later on.

DigitalOcean Account

If you haven’t signed up yet, visit digitalocean.com and create an account. DigitalOcean usually offers new users a free credit, so you can experiment without immediate costs.

Basic SSH and Linux Skills

Since DigitalOcean droplets are essentially remote Linux servers, you’ll need a basic understanding of SSH (Secure Shell) to access your droplet’s terminal. This includes knowing how to connect, run commands, and edit configuration files. If you’re new, DigitalOcean has excellent tutorials on SSH basics.

Domain Name (Optional, but Recommended)

While you can access n8n via your droplet’s IP address, using a custom domain name adds professionalism and is necessary if you want HTTPS encryption. Register a domain through any provider (e.g., Namecheap, Google Domains) and point its DNS records (A record) to your droplet’s IP.

Droplet Specifications

For n8n, a basic droplet with at least 1 GB RAM and 1 vCPU is recommended to ensure smooth performance. If you plan to run many complex workflows or handle heavy traffic, consider upgrading the specs accordingly.

Create a Droplet on DigitalOcean

DigitalOcean’s UI makes creating droplets intuitive. Here’s how to set it up optimally for n8n:

  1. Log into Your DigitalOcean Dashboard

    Navigate to the DigitalOcean Control Panel and log in.

  2. Create a New Droplet

    Click the green Create button on the top right, then choose Droplets.

  3. Choose Ubuntu 22.04 (LTS)

    Select Ubuntu 22.04 because it’s the latest long-term support release, offering security patches and compatibility for years to come.

  4. Pick Your Plan

    For most small to medium projects, the basic plan (starting at $5/month) is sufficient. This provides 1GB RAM, 1 vCPU, 25GB SSD, and 1TB bandwidth.

  5. Select a Datacenter Region

    Pick the region closest to your users to reduce latency. DigitalOcean offers locations across North America, Europe, and Asia.

  6. Add SSH Keys

    Security is paramount. Adding an SSH key means you can securely connect without using passwords. If you don’t have an SSH key pair, generate one on your local machine using ssh-keygen, then add the public key to DigitalOcean.

  7. Finalize and Create

    After naming your droplet and reviewing your settings, hit Create Droplet. The server will be ready in under a minute.

Tip: Always keep a record of your droplet IP and credentials in a safe place.

Connect to Your Droplet via SSH

Once your droplet is up, connect to it from your local terminal.

  • Find your droplet’s IP address in the DigitalOcean dashboard.
  • Open your terminal and run:
Bash
ssh root@your_droplet_ip

If you used SSH keys, you should connect without issues. Otherwise, enter your password when prompted.

Security Tip: For security reasons, avoid logging in as root for daily use. After setup, create a non-root user with sudo privileges to perform administrative tasks.

Example:

Bash
adduser yourusername
usermod -aG sudo yourusername

Then switch to your new user with:

Bash
su - yourusername

Set Up n8n Using Docker

Running n8n in Docker containers simplifies management and isolates your automation environment from the host OS.

Install Docker and Docker Compose

First, update your package list:

Bash
sudo apt update

Then install Docker and Docker Compose:

Bash
sudo apt install -y docker.io docker-compose

Verify Docker is installed and running:

Bash
docker --version
docker-compose --version

Enable Docker to start at boot:

Bash
sudo systemctl enable docker
sudo systemctl start docker

Create the Working Directory

For cleanliness and organization, create a dedicated directory for n8n files:

Bash
mkdir ~/n8n && cd ~/n8n

Define the Docker Compose File

Using your favorite text editor (nano, vim, etc.), create a docker-compose.yml:

Bash
nano docker-compose.yml

Paste the following content:

YAML
version: '3'

services:
  n8n:
    image: n8nio/n8n:latest
    restart: unless-stopped
    ports:
      - "5678:5678"
    volumes:
      - ./data:/home/node/.n8n
    environment:
      - N8N_BASIC_AUTH_ACTIVE=true
      - N8N_BASIC_AUTH_USER=${N8N_BASIC_AUTH_USER}
      - N8N_BASIC_AUTH_PASSWORD=${N8N_BASIC_AUTH_PASSWORD}
      - WEBHOOK_URL=${WEBHOOK_URL}
      - N8N_PORT=5678

Explanation:

  • image: Specifies the official n8n Docker image.
  • restart: Ensures the container restarts automatically if it crashes.
  • ports: Maps port 5678 on your droplet to the container’s port 5678.
  • volumes: Persists your workflow data and credentials outside the container, so they aren’t lost on container recreation.
  • environment: Injects environment variables to configure authentication and webhook URLs.

Set Up Environment Variables

Storing sensitive information like credentials outside code files improves security and makes management easier.

Create a .env file:

Bash
nano .env

Add:

Plaintext
N8N_BASIC_AUTH_USER=yourusername
N8N_BASIC_AUTH_PASSWORD=yourstrongpassword
WEBHOOK_URL=http://your_droplet_ip:5678/

Replace:

  • yourusername with a username you’ll use to log into n8n.
  • yourstrongpassword with a complex password to secure the UI.
  • your_droplet_ip with your server’s public IP address.

If you have a domain and HTTPS configured later, update WEBHOOK_URL accordingly.

Run n8n

Start the n8n container in detached mode with:

Bash
docker-compose up -d

To check logs and verify the container’s health:

Bash
docker-compose logs -f

You should see output confirming n8n has started and is listening on port 5678.

Accessing the n8n UI

Open your browser and go to:

Plaintext
http://your_droplet_ip:5678

You’ll be prompted for your username and password as per your .env file.

Once logged in, you can begin creating workflows that automate everything from email notifications to data syncing.

Secure Your Instance with HTTPS (Optional but Highly Recommended)

Accessing n8n over plain HTTP leaves your data and credentials vulnerable to interception. Enabling HTTPS encrypts your traffic and builds trust if you’re exposing this service publicly.

Step 1: Install Nginx

Nginx is a lightweight, high-performance web server that can act as a reverse proxy to forward HTTPS traffic to your n8n Docker container.

Bash
sudo apt install -y nginx

Step 2: Configure Nginx as Reverse Proxy

Create an Nginx configuration file:

Bash
sudo nano /etc/nginx/sites-available/n8n

Insert:

Nginx
server {
    listen 80;
    server_name yourdomain.com;

    location / {
        proxy_pass http://localhost:5678;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

Replace yourdomain.com with your actual domain name.

Enable this site:

Bash
sudo ln -s /etc/nginx/sites-available/n8n /etc/nginx/sites-enabled/

Test Nginx configuration:

Bash
sudo nginx -t

If OK, reload Nginx:

Bash
sudo systemctl reload nginx

Step 3: Install Certbot for SSL Certificates

Get Certbot and its Nginx plugin:

Bash
sudo apt install -y certbot python3-certbot-nginx

Obtain and install a free SSL certificate:

Bash
sudo certbot --nginx -d yourdomain.com

Follow the interactive prompts. Certbot will automatically configure Nginx for HTTPS and set up automatic renewals.

Step 4: Update Your .env File

Change your webhook URL to:

Plaintext
WEBHOOK_URL=https://yourdomain.com/

Restart n8n:

Bash
docker-compose down && docker-compose up -d

Now your n8n instance is securely available over HTTPS.

Set Up Persistent Data Storage

One of Docker’s strengths is volume management, which keeps your data safe between container restarts.

The ./data:/home/node/.n8n volume in your Docker Compose file stores:

  • Workflows
  • Credentials
  • Execution logs

You can back up this folder periodically or sync it with external storage solutions.

Pro Tip: For production, consider migrating n8n’s data storage to an external database such as Postgres. This improves scalability and data integrity, especially if running multiple instances.

Enable Background Workflows (Optional Advanced Setup)

For teams or projects with heavy automation needs, n8n supports running background workflows to improve performance and reliability.

How This Works

  • The main instance handles the user interface and API.
  • One or more worker instances process background tasks asynchronously.
  • A Redis queue manages communication between main and worker nodes.

Why Use Background Workers?

  • Efficiently process workflows with large execution times or resource needs.
  • Improve UI responsiveness since long-running workflows are offloaded.
  • Scale horizontally by adding more worker nodes.

Setting Up

This setup requires:

  • Running a Redis container or managed Redis service.
  • Adding environment variables like EXECUTIONS_PROCESS=queue in your Docker Compose.
  • Configuring separate worker service containers.

Because this setup is more complex, it’s recommended once you’re comfortable with basic deployment.

Updating and Maintaining n8n

Keeping n8n updated ensures you have the latest features, bug fixes, and security patches.

Updating n8n Container

Navigate to your n8n directory and pull the latest image:

Bash
docker-compose pull
docker-compose up -d

This pulls the newest version and restarts the container with minimal downtime.

Backup Best Practices

  • Regularly backup your ./data directory.
  • Export workflows from the n8n UI for added safety.
  • Consider version control for your workflows if you develop complex automations.

Monitoring and Logs

Use:

Bash
docker-compose logs -f

to monitor real-time logs for troubleshooting.
