# Homelab Caddyfile — the single Caddy for both hosts.
#
# Caddy runs as a container on dankclaw (192.168.0.143, this repo's
# compose.yaml service 'caddy') and fronts every service on both hosts:
#   - dankclaw services: by container name (compose network) or by the
#     published LAN port (quadlet services on isolated networks)
#   - dankserver services (192.168.0.235): by published LAN port
#
# Naming: flat franksdank.cloud scheme (see serverAppConfigs-docs/Infrastructure/LAN-DNS.md).
# DNS for these names is served by the Pi-hole quadlet on this host
# (dankclaw/pihole/addn-hosts — every name resolves to 192.168.0.143)
# and handed to LAN clients by the SURFboard G36 router.
#
# Authentication chain (Anubis rollout, 2026-08-28): the guarded vhosts
# (homepage, SearXNG, Hermes, Prometheus, RomM, Copyparty) proxy EVERYTHING
# through the Anubis bot-challenge proxy first. Chain: client → Caddy (TLS,
# public listener) → Anubis :8923 (verify: DENY known AI scrapers, CHALLENGE
# everyone else) → Caddy's internal listener http://:8016 (Authentik
# forward_auth + app routing resumes; Host headers survive both hops) → app.
# Apps with their own auth (Grafana, Gitea, OpenWebUI, ComfyUI, Jellyfin,
# *arr, Pi-hole) and the Authentik IdP itself (auth.franksdank.cloud — its
# login flow must never sit behind a challenge) are exempt by construction:
# their vhosts never route through Anubis. The basicauth hash is a
# placeholder; deploy.sh renders the real hash (CADDY_BASICAUTH_HASH from the
# host .env, git-ignored) into /home/dank/Containers/caddy/Caddyfile, which
# the container mounts.
#
# TLS: real Let's Encrypt certs. Site addresses carry no http:// prefix,
# so Caddy serves HTTPS (and auto-redirects HTTP). Certs are issued via
# dns-01 through the Porkbun module built into the franksdank/caddy-porkbun
# image (caddy/Containerfile). That needs no inbound ports and works from the
# LAN, where Pi-hole resolves these names to 192.168.0.143.

{
	# Admin stays ON: it binds to 127.0.0.1:2019 inside the container and the
	# port is not published, so nothing outside the container can reach it.
	# It powers the config file watcher, so a rendered-config change
	# hot-reloads without a container restart. 'admin off' once left a broken
	# basicauth hash sitting on disk unapplied for hours (2026-08-22).
