Follow-up to Frigate's Authelia integration: both of these can also skip
their own login entirely once Authelia is doing the gating, each with a
different trust model appropriate to what the app actually supports.
- gitea: new _gitea_offer_reverse_proxy_auth(), a second Authelia
integration alongside the existing OIDC "Sign in with Authelia" button.
Enables Gitea's own ENABLE_REVERSE_PROXY_AUTHENTICATION so it auto-logs
in from a trusted Remote-User header — no click, no separate Gitea
session to expire on its own. Trust is IP-range based
(REVERSE_PROXY_TRUSTED_PROXIES), computed from caddy_net's real subnet
the same way ufw_allow_from_caddy_net does; refuses to enable the
feature at all if that can't be determined rather than fall back to a
permissive default — Gitea's own Docker image has shipped an unscoped
default before (GHSA-f75j-4cw6-rmx4, any IP could impersonate any user).
Rewires Gitea onto caddy_net and re-points Caddy at gitea:3000, since it
previously only reached Caddy via its published host port. Gitea's own
login stays available as a fallback, so unlike Frigate there's no
"native login off with nothing gating it" state to guard against.
- uptimekuma: sets DISABLE_AUTH=true only once Caddy's "import authelia"
gate is confirmed in front of it. Uptime Kuma already joined caddy_net
unconditionally, so this only needed the env var plus moving the
Authelia-gated Caddy call earlier (before docker-compose.yml is
written); the existing unconditional call at the end now only runs as a
fallback when the Authelia path wasn't used or wasn't completed. Kuma's
DISABLE_AUTH has no IP-scoping or secret check left once set — the
strictest of the three to get the ordering right on, since a mistake
here means wide open, not just spoofable.
Verified with a local test harness (fake Authelia/Caddy/docker-network
state): both the happy path and the "Caddy declined" safety fallback
produce the expected docker-compose.yml/.env/Caddyfile output for each
service, and Gitea's subnet-detection refusal + idempotent-rerun guard
were exercised directly.
