Setting Up Workflow Automation with n8n and Supabase on Render

In this article, we will walk through how to deploy n8n, a powerful open-source workflow automation tool, using Render’s cloud platform and integrate it with Supabase to handle backend data and configurations. By the end, you’ll have a working automation system hosted on the cloud, ready to handle various workflow needs.

What is n8n?

n8n is an open-source automation tool that enables users to create workflows connecting different services without writing extensive code. From scheduling tasks to integrating APIs, it streamlines complex processes, making it an ideal solution for automation enthusiasts and businesses alike.

Prerequisites

Before diving into the setup, ensure you have:

Both Render and Supabase provide free-tier services, making them excellent options for hobby projects and evaluations.

Step 1: Setting Up n8n on Render

First, create an account on Render and head over to the web service setup section.

  1. Start New Service: Select “Web Service” and choose “Existing Image.” Image URL: docker.n8n.io/n8nio/n8n
  2. Configure Docker Image: Use the image URL provided in the description to pull the n8n image into Render.
  3. Choose Region: It’s essential to choose a region close to your location to minimize latency. For example, if you’re based in Europe, Frankfurt is a solid option.
  4. Select Free Tier: For smaller projects or evaluations, Render’s free tier works well. However, note that inactivity may cause the service to enter sleep mode, causing a slight delay upon the next request.
  5. Add the following Environment variables:
DB_POSTGRESDB_DATABASE
DB_POSTGRESDB_HOST
DB_POSTGRESDB_PASSWORD
DB_POSTGRESDB_PORT
DB_POSTGRESDB_SCHEMA
DB_POSTGRESDB_USER
DB_TYPE
GENERIC_TIMEZONE
N8N_ENCRYPTION_KEY
TZ

Step 2: Configuring Environment Variables

Now that n8n is being set up, it’s time to configure environment variables. These are necessary for the n8n instance to interact with Supabase and other services.

  1. Add Environment Variables: Render allows you to pre-fill critical environment variables such as:
  • Database Type: Postgres
  • Schema: Public
  • Time Zone: Adjust this to your region, such as “Europe/London” or “America/New York”
  1. Configure Additional Variables: Once Supabase is integrated, you’ll come back to add more specific variables, including encryption keys.

Step 3: Setting Up Supabase

Supabase will act as the backend database for storing configurations, workflow data, and other relevant information.

  1. Create a New Project: Log into Supabase and create a new project. Be sure to select the same region as Render to avoid latency issues.
  2. Save Credentials: Generate a password and save it to your clipboard, as you’ll need it shortly for Render.
  3. Database Details: After the project setup is complete, navigate to the database settings and copy credentials like host, port, and user information. These will be required for n8n’s environment variables.

Step 4: Completing the Setup in Render

Now, return to Render and finish configuring the environment variables.

  1. Postgres User & Host: Add the details you copied from Supabase.
  2. Generate Encryption Key: Use an online tool to generate a random encryption key. This key ensures your database remains secure.

Once all variables are in place, deploy your web service. The system will take a few minutes to initialize.

Step 5: Accessing n8n for the First Time

After deployment, a “Live” indicator will appear on your Render dashboard. Click the provided link to access your n8n instance and create your admin account. Follow the on-screen instructions to set up your credentials.

Step 6: Creating Your First Workflow

Let’s create a simple workflow to verify everything is functioning correctly.

  1. Create Workflow: Name your workflow and start by adding a “Webhook” node, which acts as an API endpoint. Configure it to respond with a JSON object when accessed.
  2. Test Workflow: Use the provided test URL and paste it into your browser. Upon hitting enter, you should see a response indicating the workflow is working as expected.

Step 7: Keeping n8n Updated

It’s essential to periodically update your n8n instance to benefit from bug fixes and new features. In the bottom left corner of the n8n dashboard, you will see notifications about new updates. To apply updates:

  1. Go to Settings: Navigate to the Render settings and change the deployment version from “Latest” to the newest release, which you can find on the n8n platform.
  2. Save and Deploy: Save your changes, and the service will automatically redeploy with the latest version.

Final Thoughts

Congratulations! You’ve successfully set up n8n with Supabase on Render, allowing you to automate workflows, manage backend tasks, and streamline various processes. Regular updates and environment variable management are essential for efficient and secure workflows.
