Hey there, fellow developers! 👋 Today, I'm excited to share a straightforward guide on deploying n8n on Fly.io. If you're looking for a cost-effective way to host your workflow automation tool, this tutorial is for you!
What is n8n?
Before we dive in, let me quickly explain what n8n is. n8n (pronounced "n-eight-n") is an excellent open-source workflow automation tool, similar to Zapier or Make (formerly Integromat). It allows you to connect different services and automate tasks with a beautiful visual interface. The best part? You can self-host it!
Why Fly.io?
Fly.io offers a generous free tier and makes deployment super simple. Plus, they have data centers worldwide, so you can host your n8n instance close to where you need it. They also provide automatic SSL certificates and a straightforward CLI tool.
Prerequisites
Before we start, make sure you have:
- A Fly.io account (sign up at fly.io)
- Basic command line knowledge
- A cup of coffee ☕
Let's Get Started!
1. Install the Fly.io CLI
First, we need to install the Fly.io command-line tool. On Windows, open PowerShell and run:
powershell -Command "iwr https://fly.io/install.ps1 -useb | iex"
For other operating systems, check out Fly.io's installation guide.
2. Deploy n8n
I've created a repository that makes deploying n8n on Fly.io super easy. Here's what you need to do:
# Clone the repository
git clone https://github.com/gijs-epping/n8n-fly.git
cd n8n-fly
# Launch your app
fly launch
When you run fly launch, you'll see a configuration screen where you can:
- Choose your app name (it needs to be unique)
- Select your region
- Configure resources (1GB RAM and shared CPU is usually enough to start)
3. Configure Your Application
The magic happens in your fly.toml file. Here's what you need to pay attention to:
app = "your-unique-app-name" # Choose wisely!
primary_region = "ams" # Pick a region close to you
4. First-Time Setup
Once deployed, visit your new n8n instance at https://your-app-name.fly.dev. You'll be greeted with a setup screen where you can create your admin account:
Pro Tips 🚀
Resource Management
Fly.io will automatically stop your instance when it's idle, saving you resources. This is perfect for personal use or testing! But beware, webhooks don't work when it is offline.Custom Domain
Want to use your own domain? It's as simple as:
fly certs add your-domain.com
- Monitoring Keep an eye on your app with:
fly status
fly logs
Troubleshooting Common Issues
Application Not Starting?
Check your logs:
fly logs
DNS Issues?
Make sure your app name matches in all configurations:
fly.toml- Environment variables
- URLs in your n8n settings
Resource Issues?
The default configuration (1GB RAM, shared CPU) should work fine for most use cases. If you need more, you can scale up using:
fly scale memory 2048
Cost Considerations 💰
Fly.io's free tier includes:
- 3 shared-cpu-1x VMs
- 3GB total memory
- 160GB outbound data transfer
This is perfect for running a personal n8n instance!
What's Next?
Now that you have n8n running, here are some cool things you can do:
- Create your first workflow
- Connect with external services
- Set up webhook automations
- Explore n8n's node library
Conclusion
Deploying n8n on Fly.io is a fantastic way to get your own workflow automation server up and running quickly and affordably. The setup is straightforward, and the maintenance is minimal.
