Let's Encrypt

Let's Encrypt provides free SSL certificates trusted by most browsers, ideal for production environments.

Prerequisites

• Certbot installed on your system.
• DNS records properly configured to point to your server.

Steps

1. Create Directories for Nginx Files:

   mkdir -p conf.d ssl
   

2. Create Nginx Configuration File:

   conf.d/open-webui.conf:

   server {
       listen 80;
       server_name your_domain_or_IP;
   
       location / {
           proxy_pass http://host.docker.internal:3000;
           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;
   
           # (Optional) Disable proxy buffering for better streaming response from models
           proxy_buffering off;
       }
   }
   

3. Simplified Let's Encrypt Script:

   enable_letsencrypt.sh:

   #!/bin/bash
   
   # Description: Simplified script to obtain and install Let's Encrypt SSL certificates using Certbot.
   
   DOMAIN="your_domain_or_IP"
   EMAIL="your_email@example.com"
   
   # Install Certbot if not installed
   if ! command -v certbot &> /dev/null; then
       echo "Certbot not found. Installing..."
       sudo apt-get update
       sudo apt-get install -y certbot python3-certbot-nginx
   fi
   
   # Obtain SSL certificate
   sudo certbot --nginx -d "$DOMAIN" --non-interactive --agree-tos -m "$EMAIL"
   
   # Reload Nginx to apply changes
   sudo systemctl reload nginx
   
   echo "Let's Encrypt SSL certificate has been installed and Nginx reloaded."
   

   Make the script executable:

   chmod +x enable_letsencrypt.sh
   

4. Update Docker Compose Configuration:

   Add the Nginx service to your docker-compose.yml:

   services:
     nginx:
       image: nginx:alpine
       ports:
         - "80:80"
         - "443:443"
       volumes:
         - ./conf.d:/etc/nginx/conf.d
         - ./ssl:/etc/nginx/ssl
       depends_on:
         - open-webui
   

5. Start Nginx Service:

   docker compose up -d nginx
   

6. Run the Let's Encrypt Script:

   Execute the script to obtain and install the SSL certificate:

   ./enable_letsencrypt.sh
