Automated HTTPS and reverse proxy setup for AI service endpoints
Core Idea:
Caddy Server provides automatic HTTPS certificate management and reverse proxy capabilities to secure AI services and make them accessible through clean, subdomain-based URLs.
Key Principles:
- Automatic TLS/SSL:
- Caddy obtains and renews Let's Encrypt certificates without manual intervention.
- Reverse Proxy Routing:
- Maps external subdomains to internal services running on specific ports.
- Configuration Simplicity:
- Uses a declarative configuration approach with minimal syntax for complex setups.
Why It Matters:
- Security Enhancement:
- Encrypts all traffic between users and AI services, protecting sensitive data.
- Professional Access:
- Provides clean URLs (like n8n.yourdomain.com) instead of IP:port combinations.
- Authentication Layer:
- Can add an additional authentication barrier before traffic reaches internal services.
How to Implement:
- Install Caddy in Docker Compose:
caddy:
image: caddy:2
restart: unless-stopped
ports:
- "80:80"
- "443:443"
volumes:
- ./Caddyfile:/etc/caddy/Caddyfile
- caddy_data:/data
- caddy_config:/config
- Configure Basic Caddyfile:
n8n.yourdomain.com {
reverse_proxy n8n:5678
tls your-email@example.com
}
supabase.yourdomain.com {
reverse_proxy supabase:3000
tls your-email@example.com
}
- Set Environment Variables:
CADDY_N8N_HOSTNAME=n8n.yourdomain.com
CADDY_SUPABASE_HOSTNAME=supabase.yourdomain.com
CADDY_OPENWEBUI_HOSTNAME=openwebui.yourdomain.com
CADDY_EMAIL=your-email@example.com
Example:
- Scenario:
- Configuring secure access to the Local AI Package services through custom subdomains.
- Application:
Complete Caddyfile configuration for multiple services:
{
email your-email@example.com
}
n8n.yourdomain.com {
reverse_proxy n8n:5678
}
supabase.yourdomain.com {
reverse_proxy supabase:3000
}
openwebui.yourdomain.com {
reverse_proxy openwebui:3000
}
flowise.yourdomain.com {
reverse_proxy flowise:3000
}
- Result:
- All services are accessible via HTTPS on their respective subdomains, with automatic certificate management and renewal.
