Configuring domain names and subdomains for cloud-hosted AI infrastructure

Core Idea:

DNS setup for AI services creates user-friendly, secure access points to each component of your AI stack through custom domains and subdomains, enabling HTTPS connections and organized service management.

Key Principles:

1. Subdomain Isolation:
   • Each AI service receives its own subdomain for independent access and security isolation.
2. IP Mapping:
   • DNS A records map human-readable domains to the server's IP address.
3. TLS Integration:
   • Domain configuration enables HTTPS security through certificate management tools like Caddy.

Why It Matters:

• Usability:
  • Team members can access services through memorable URLs rather than IP addresses and port numbers.
• Security:
  • Enables HTTPS encryption for all services through proper certificate management.
• Organizational Clarity:
  • Creates a structured naming system for different components of your AI infrastructure.

How to Implement:

1. Choose Base Domain:
   Select an existing domain you control (e.g., yourdomain.com)

2. Create A Records:

   Type: A
   RecordName: n8n (subdomain)
   Value: [Your Server IP]
   TTL: 3600 (or Auto)
   

3. Repeat for Each Service:

   Create additional A records for each service:

   • supabase.yourdomain.com
   • openwebui.yourdomain.com
   • flowise.yourdomain.com

Example:

• Scenario:

  • Setting up DNS for a Local AI Package deployed on Digital Ocean with IP 203.0.113.10.

• Application:
  In your DNS provider (e.g., Hostinger, Cloudflare, etc.), create the following records:

  A Record: n8n.yourdomain.com → 203.0.113.10
  A Record: supabase.yourdomain.com → 203.0.113.10
  A Record: openwebui.yourdomain.com → 203.0.113.10
  A Record: flowise.yourdomain.com → 203.0.113.10
  

• Result:

  • Users can access each service via its dedicated subdomain (e.g., https://n8n.yourdomain.com) with proper HTTPS encryption.
