Domain Configuration

The project uses two domains, both served through the same nginx container on ports 80 and 443.

Domains

Domain	Purpose	Upstream
ictedgefund.com	Main dashboard	host.docker.internal:8000 (Node.js on host)
docs.ictedgefund.com	This wiki	docs container (MkDocs via Docker)

DNS Records

Both domains require A records pointing to the server's public IP address:

Type	Name	Value
A	ictedgefund.com	<server IP>
A	docs.ictedgefund.com	<server IP>

Both records must point to the same IP since a single nginx instance handles all traffic.

Traffic Flow

Client
  |
  v
nginx (port 80/443)
  |
  |-- Host: ictedgefund.com      --> proxy_pass to host.docker.internal:8000
  |-- Host: docs.ictedgefund.com --> proxy_pass to docs container

Nginx uses the server_name directive to match the incoming Host header and route the request to the correct upstream. Both server blocks share the same TLS certificate (issued for both names via certbot).

Adding a New Subdomain

To add another subdomain:

1. Create a DNS A record pointing to the server IP
2. Add a new server block in nginx/nginx.conf with the appropriate server_name and proxy_pass
3. Re-issue the TLS certificate to include the new name (see Certbot)
4. Reload nginx: docker compose exec nginx nginx -s reload
