Reverse Proxy (Caddy)

Caddy serves as the primary ingress point for all web services in the Flora Family homelab. It handles SSL termination (ACME), local CA management, and request routing.

🏗️ Structure

Location: /srv/caddy
User: 51004:61004 (Caddy Service Account)
Snippets Path: /main/appdata/caddy/files/snippets (Mapped internally to /etc/caddy/snippets)

📝 Caddyfile Strategy

The Caddyfile is organized into modular sites located in sites-enabled/. This mimics traditional Apache/Nginx structures for clean management.

Common Snippets

security_headers.caddy: Implements HSTS, X-Frame-Options (DENY), and nosniff.
common_tls_internal.caddy: Uses tls internal for services only accessible on the LAN, backed by the local Caddy CA.
common_tls_external.caddy: Standard ACME/Let's Encrypt for public-facing services.
