Prerequisites for Installing n8n

Before starting the installation, there are a few things you’ll need:

  1. A machine or server to run n8n (can be local or cloud-based).
  2. Docker: n8n can be installed using Docker, which makes the installation process much easier.
  3. Node.js (Optional): You can install n8n without Node.js if you’re using Docker.

Make sure you have Docker installed on your machine before proceeding with the steps. If not, you can download Docker here.

Step-by-Step Guide to Installing n8n

Step 1: Install Docker

If you don’t have Docker installed, you can easily install it on most operating systems. Follow these instructions:

For macOS and Windows:

  1. Download the Docker Desktop application from Docker’s website.
  2. Install the downloaded file by following the on-screen instructions.
  3. After installation, open Docker Desktop and allow it to set up.

For Linux:

You can install Docker on Linux by following the official Docker guide for your distribution. For example, on Ubuntu, run the following commands:

sudo apt-get update
sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt-get update
sudo apt-get install docker-ce

Step 2: Pull the n8n Docker Image

Once Docker is installed, you can proceed with pulling the official n8n Docker image. Open your terminal or command prompt and run the following command:

docker pull n8nio/n8n

This command will download the latest n8n image from Docker Hub.

Step 3: Run n8n Using Docker

After pulling the n8n image, you can run it with the following Docker command. This will start n8n and make it accessible through a web interface:

docker run -d \
  -p 5678:5678 \
  --name n8n \
  -e GENERIC_TIMEZONE="Europe/Berlin" \
  -v ~/.n8n:/root/.n8n \
  n8nio/n8n

Let’s break down the command:

  • -d: Run n8n in the background (detached mode).
  • -p 5678:5678: Map port 5678 of your local machine to port 5678 of the Docker container. You can access n8n through http://localhost:5678.
  • --name n8n: Assign the name “n8n” to your Docker container.
  • -e GENERIC_TIMEZONE="Europe/Berlin": Set the timezone for n8n.
  • -v ~/.n8n:/root/.n8n: Mount the ~/.n8n directory on your local machine to store n8n data persistently.

Step 4: Access the n8n Web Interface

Once the Docker container is running, open a web browser and go to:

http://localhost:5678

You should see the n8n interface. From here, you can start creating workflows using the visual editor. The default login credentials are not set, so you can access it directly.

Step 5: Configure n8n for Production (Optional)

If you want to use n8n in a production environment, you may need to configure additional settings such as SSL encryption or a reverse proxy. You can also set up a database for storing workflows if you want more control over the data.

To enable SSL, you can use a reverse proxy like NGINX. You can also configure authentication and API access if needed.

Step 6: Create Your First Workflow

Once n8n is running, it’s time to create your first workflow. Here’s a quick guide:

  1. Click on the “Create” button to start a new workflow.
  2. Drag and drop nodes to connect different services (e.g., Gmail, Google Sheets, Slack).
  3. Configure the nodes with your credentials and workflow logic.
  4. Once done, hit “Execute Workflow” to test it.

You can save your workflow and run it automatically based on triggers.

Conclusion

n8n is an incredibly versatile automation tool that can help automate tasks in various domains. By following the steps above, you can easily install and set up n8n using Docker. Whether you’re automating simple tasks or complex workflows, n8n provides a flexible, open-source solution that gives you full control over your processes.
