Setting Up Your Environment

Before deploying n8n with Kamal, it’s crucial to properly set up your environment. This section will guide you through installing Kamal, configuring your development environment, and preparing your n8n application for deployment.

Installing Kamal

Kamal is a Ruby gem, which makes installation straightforward:

Ensure you have Ruby 2.7 or later installed on your system. You can check your Ruby version by running:
```
ruby --version
```
Install Kamal using the gem command:
```
gem install kamal
```
Verify the installation by checking the Kamal version:
```
kamal version
```

If you see the version number, Kamal has been successfully installed.

Configuring your development environment

With Kamal installed, let’s set up your development environment:

Create a new directory for your n8n project:

mkdir n8n-kamal-project
cd n8n-kamal-project

Initialise a Git repository:
```
git init
```
Create a .gitignore file to exclude sensitive information:
```
touch .gitignore
echo ".env" >> .gitignore
```
Set up SSH key authentication for your server. If you haven’t already:
```
ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
```
Then, add your public key to your server’s ~/.ssh/authorized_keys file.
Install Docker if you haven’t already. Follow the official Docker documentation for your operating system.

Preparing your n8n application

Now, let’s prepare the n8n application for deployment:

Create a Dockerfile in your project directory:
```
touch Dockerfile
```

Add the following content to the Dockerfile:

FROM n8nio/n8n:latest

ENV NODE_ENV=production
ENV N8N_PORT=5678
ENV N8N_PROTOCOL=https
ENV N8N_HOST=your-domain.com

EXPOSE 5678

Replace your-domain.com with your actual domain.

Create a .env file for local development (remember, this shouldn’t be committed to Git):
```
touch .env
```
Add any necessary environment variables, such as:
```
N8N_BASIC_AUTH_ACTIVE=true
N8N_BASIC_AUTH_USER=admin
N8N_BASIC_AUTH_PASSWORD=your-secure-password
```

Create a docker-compose.yml file for local testing:

version: '3'
services:
  n8n:
    build: .
    ports:
      - "5678:5678"
    env_file:
      - .env
    volumes:
      - ~/.n8n:/home/node/.n8n

This setup allows you to test your n8n instance locally before deployment. Run docker-compose up --build to start n8n locally and access it at http://localhost:5678.

With your environment set up and n8n prepared for deployment, you’re ready to move on to configuring Kamal for n8n deployment in the next section.

Configuring Kamal for n8n Deployment

Proper configuration of Kamal is crucial for a successful n8n deployment. This section will guide you through creating a Kamal configuration file, customising settings for n8n, and setting up the necessary environment variables.

Creating a Kamal configuration file

In your project directory, initialise a new Kamal configuration:
```
kamal init
```
This creates a config/deploy.yml file.
Open config/deploy.yml in your preferred text editor. Replace its contents with the following basic configuration:
```
service: n8n
image: your-docker-username/n8n
servers:
  - your-server-ip
registry:
  username: 
  password:
env:
  clear:
    PORT: 5678
volumes:
  - /home/ubuntu/.n8n:/home/node/.n8n
```
Replace your-docker-username with your Docker Hub username and your-server-ip with your server’s IP address.

Customising settings for n8n

Now, let’s customise the Kamal configuration for n8n:

Add health check settings to ensure smooth deployments:

healthcheck:
  path: /
  port: 5678
  max_attempts: 10

Configure SSL using Let’s Encrypt:
```
ssl:
  letsencrypt:
    email: your-email@example.com
    domains:
      - your-domain.com
```
Replace your-email@example.com and your-domain.com with your actual email and domain.
Set up a builder for multi-architecture support:
```
builder:
  multiarch: true
```
Configure asset hosting if needed:
```
assets:
  - public
```

Setting up environment variables

Properly configuring environment variables is crucial for n8n’s functionality and security:

Create a .env file in your project root (if you haven’t already):
```
touch .env
```

Add the following variables to your .env file:

N8N_BASIC_AUTH_ACTIVE=true
N8N_BASIC_AUTH_USER=your-username
N8N_BASIC_AUTH_PASSWORD=your-secure-password
N8N_PROTOCOL=https
N8N_HOST=your-domain.com
N8N_PORT=5678
N8N_ENCRYPTION_KEY=your-long-random-string

Replace the placeholders with your actual values. Generate a strong random string for N8N_ENCRYPTION_KEY.

Update your config/deploy.yml to include these environment variables:

env:
  secret:
    - N8N_BASIC_AUTH_ACTIVE
    - N8N_BASIC_AUTH_USER
    - N8N_BASIC_AUTH_PASSWORD
    - N8N_PROTOCOL
    - N8N_HOST
    - N8N_PORT
    - N8N_ENCRYPTION_KEY

To securely transfer these environment variables to your server, use:
```
kamal env push
```
This command encrypts and uploads your environment variables to the server.

By following these steps, you’ve created a Kamal configuration tailored for n8n, customised important settings, and securely set up your environment variables. This configuration ensures that your n8n instance will be deployed with the correct settings and security measures in place.

In the next section, we’ll cover the actual deployment process using this configuration.

Deploying n8n with Kamal

With your environment set up and Kamal configured, you’re ready to deploy n8n. This section will guide you through building the Docker image, pushing it to a registry, and executing the deployment using Kamal.

Building the Docker image

Before deploying, you need to build a Docker image of your n8n application:

Ensure you’re in your project directory.
Build the Docker image using Kamal:
```
kamal build
```
This command uses the Dockerfile in your project to build the image. It also tags the image based on the configuration in your deploy.yml file.
If successful, you’ll see output indicating that the image was built and tagged.

Pushing the image to a registry

After building the image, you need to push it to a Docker registry:

If you haven’t already, log in to your Docker registry (e.g., Docker Hub):
```
docker login
```
Push the image to the registry using Kamal:
```
kamal push
```
This command pushes the built image to the registry specified in your deploy.yml file.
Kamal will display progress information as it pushes the image layers to the registry.

Executing the deployment

With the image built and pushed, you’re ready to deploy n8n:

Deploy n8n using the following command:
```
kamal deploy
```
Kamal will perform the following steps:
- Connect to your server(s)
- Pull the latest image
- Stop the existing containers (if any)
- Start new containers with the updated image
- Perform health checks to ensure the application is running correctly
Monitor the output for any errors or warnings. A successful deployment will end with a message indicating that the deployment is complete.
If this is your first deployment, Kamal will also set up Traefik as a reverse proxy and configure SSL using Let’s Encrypt (based on your deploy.yml settings).
To verify the deployment, you can use:
```
kamal app status
```
This will show you the status of your deployed containers.
Access your n8n instance by navigating to your domain in a web browser. You should see the n8n login page.

If you need to make changes or update your n8n instance in the future, simply repeat these steps:

Make your changes locally
Build a new Docker image (kamal build)
Push the new image to the registry (kamal push)
Deploy the updated image (kamal deploy)

Kamal will handle the process of updating your live instance with zero downtime.

By following these steps, you’ve successfully deployed n8n using Kamal. Your instance is now running on your server, secured with SSL, and ready for use. In the next section, we’ll cover post-deployment configuration to further enhance and secure your n8n setup.

Post-Deployment Configuration

After successfully deploying n8n with Kamal, there are several important steps to ensure your instance is properly configured, secure, and accessible. This section covers setting up a domain name, configuring SSL/TLS, and implementing additional security measures for your n8n instance.

Setting up a domain name

While Kamal handles much of the domain configuration, you’ll need to set up your domain name to point to your server:

If you haven’t already, purchase a domain name from a domain registrar.
Log in to your domain registrar’s control panel.
Locate the DNS management section.
Create an A record pointing your domain to your server’s IP address:
- Type: A
- Host: @ (or leave blank for root domain)
- Value: Your server’s IP address
- TTL: 3600 (or as low as your registrar allows)
If you want to use a subdomain (e.g., n8n.yourdomain.com), create a CNAME record instead:
- Type: CNAME
- Host: n8n (or your chosen subdomain)
- Value: Your root domain (yourdomain.com)
- TTL: 3600
Wait for DNS propagation, which can take up to 48 hours, though often completes much sooner.

Configuring SSL/TLS

Kamal and Let’s Encrypt handle most of the SSL/TLS configuration automatically, but it’s important to verify and understand the setup:

Confirm SSL is working by accessing your n8n instance via HTTPS in a web browser.
Check the SSL certificate details in your browser to ensure it’s valid and issued by Let’s Encrypt.
If you encounter any SSL issues, you can force Kamal to renew the certificate:
```
kamal cert renew
```

To enable automatic renewal, ensure your deploy.yml includes:

ssl:
  letsencrypt:
    email: your-email@example.com
    domains:
      - your-domain.com

Kamal will handle certificate renewal automatically during future deployments.

Securing your n8n instance

While basic authentication is set up through environment variables, consider these additional steps to enhance security:

Update your config/deploy.yml to restrict access to specific IP addresses if needed:
```
traefik:
  options:
    - "http.middlewares.ipwhitelist.ipwhitelist.sourcerange=192.168.1.7/32,127.0.0.1/32"
```
Replace the IP addresses with your allowed IPs.
Enable two-factor authentication (2FA) for your n8n instance:
- Log in to your n8n instance
- Go to Settings > Security
- Enable and configure 2FA according to n8n’s documentation
Regularly update your n8n instance to the latest version:
```
kamal app update
```
Implement a strong password policy for n8n users.
Restrict outbound connections from your server using a firewall (e.g., UFW on Ubuntu):
```
sudo ufw default deny outgoing
sudo ufw allow out 80,443/tcp
sudo ufw enable
```
Regularly audit your workflows and user access to ensure they align with your security policies.
If you’re storing sensitive data, consider encrypting your n8n database:
- Update your deploy.yml to include the necessary environment variables
- Use Kamal to update these variables on your server:
```
kamal env push
```
Monitor your server and n8n logs for any suspicious activity:
```
kamal app logs
```

By implementing these post-deployment configurations, you’ve ensured that your n8n instance is accessible via a custom domain, secured with SSL/TLS, and protected against common security threats. Regular maintenance and updates will help keep your instance secure and running smoothly.
