Install Docker Compose

sudo apt install docker-compose-plugin

Copy code
docker compose version

NGINX Example

1. Install NGINX:

bash

Copy code
sudo apt install nginx

Configure NGINX for n8n: Create a file /etc/nginx/sites-available/n8n with the following content:

nginx

Copy code
server { listen 80; server_name <your-public-domain>; location / { proxy_pass http://localhost:5678; 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 $scheme; client_max_body_size 50M; } }

Enable the site and reload NGINX:

bash

Copy code
sudo ln -s /etc/nginx/sites-available/n8n /etc/nginx/sites-enabled/ sudo nginx -t sudo systemctl reload nginx

If you get an 400 error this is the fix:

server {

  # Existing configuration...

  client_header_buffer_sTest the configuration for syntax errors:

bash

Copy code
sudo nginx -t

Reload NGINX to apply changes:

bash

Copy code
sudo systemctl reload nginx

ize 16k;

  large_client_header_buffers 4 32k;

}
