# Self-Hosting SSL enabled N8N on a Linux Server

This guide provides step-by-step instructions to self-host [n8n](https://n8n.io), a free and open-source workflow automation tool, on a Linux server using Docker, Nginx, and Certbot for SSL with a custom domain name.

## Step 1: Installing Docker

1. **Update the Package Index:**
   ```bash
   sudo apt update

2. **Install Docker:**
    ```bash
    sudo apt install docker.io

3.  **Start Docker:**
    ```bash
    sudo systemctl start docker

4. **Enable Docker to Start at Boot:**
    ```bash
    sudo systemctl enable docker

## Step 2: Starting n8n in Docker

**Run the following command to start n8n in Docker. Replace your-domain.com with your actual domain name:**

```bash
sudo docker run -d --restart unless-stopped \
  --name n8n \
  -p 5678:5678 \
  -e N8N_HOST="your-domain.com" \
  -e N8N_PROTOCOL="https" \
  -e WEBHOOK_URL="https://your-domain.com" \
  -v n8n_data:/home/node/.n8n \
  docker.n8n.io/n8nio/n8n
```

**Or if you are using a subdomain, it should look like this:**

```bash
sudo docker run -d --restart unless-stopped \
  --name n8n \
  -p 5678:5678 \
  -e N8N_HOST="subdomain.your-domain.com" \
  -e N8N_PROTOCOL="https" \
  -e WEBHOOK_URL="https://subdomain.your-domain.com" \
  -v n8n_data:/home/node/.n8n \
  docker.n8n.io/n8nio/n8n
```

This command does the following:

- Downloads and runs the n8n Docker image.
- Exposes n8n on port 5678.
- Sets environment variables for the n8n host and webhook tunnel URL.
- Mounts the n8n data directory for persistent storage.
- After executing the command, n8n will be accessible on your-domain.com:5678.

## Step 3: Installing Nginx

Nginx is used as a reverse proxy to forward requests to n8n and handle SSL termination.

1. **Install Nginx:**
    ```bash
    sudo apt install nginx

## Step 4: Configuring Nginx

Configure Nginx to reverse proxy the n8n web interface:

1. **Create a New Nginx Configuration File:**
    ```bash
    sudo nano /etc/nginx/sites-available/n8n.conf

2. **Paste the Following Configuration:**
    ```bash
    server {
        listen 80;
        server_name your-domain.com; // subdomain.your-domain.com if you have a subdomain

location / {
        proxy_pass http://localhost:5678;
        proxy_http_version 1.1;
        chunked_transfer_encoding off;
        proxy_buffering off;
        proxy_cache off;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto https;
        proxy_read_timeout 86400;
        }
    }
    ```
    Replace your-domain.com with your actual domain.

3. **Enable the Configuration:**
    ```bash
    sudo ln -s /etc/nginx/sites-available/n8n.conf /etc/nginx/sites-enabled/

4. **Test the Nginx Configuration and Restart:**
    ```bash
    sudo nginx -t
    sudo systemctl restart nginx
    ```

## Step 5: Setting up SSL with Certbot

Certbot will obtain and install an SSL certificate from Let's Encrypt.

1. **Install Certbot and the Nginx Plugin:**
    ```bash
    sudo apt install certbot python3-certbot-nginx

2. **Obtain an SSL Certificate:**
    ```bash
    sudo certbot --nginx -d your-domain.com
    // If you have a subdomain then it will be subdomain.your-domain.com

Follow the on-screen instructions to complete the SSL setup.
Once completed, n8n will be accessible securely over HTTPS at your-domain.com.

IMPORTANT: Make sure you follow the above steps in order. Step 5 will modify your /etc/nginx/sites-available/n8n.conf file to something like this:

By using Nginx and Certbot, you ensure that your n8n instance is securely accessible over the internet with HTTPS.

## Step 6: Reserve Static IP

Goto Google Cloud -> VPC Network -> IP Addresses

Find your External IP Address of Virtual Machine Created

## Updating n8n

New n8n versions are released regularly. **Do not** just pull a new image and hope
for the best — n8n runs one-way database migrations on startup, so once a newer
version has upgraded your database, the old version can no longer start against it.
Always back up first.

👉 **[Follow the update guide here: update/README.MD](update/README.MD)**

It covers backing up your data, taking a Compute Engine snapshot, swapping the
container to the new version, and what to do if your workflows don't appear in the
UI afterwards.
