# Quadlet unit: Anubis bot-challenge proxy (rootless, boot-persistent).
#
# Install path on dankclaw: ~/.config/containers/systemd/anubis.container
# Unit name: anubis.service (container name: anubis)
#
# Two-tier chain: the public Caddy listeners for the guarded vhosts proxy
# everything to this container (port 8923, internal only — no published port,
# so metrics on :9090 stay reachable only inside dankclaw_default); Anubis
# verifies the client (challenge/DENY per policy) and forwards accepted
# traffic back to Caddy's internal listener (TARGET below), where the normal
# per-vhost routing — including Authentik forward_auth — resumes. Host headers
# survive both hops, so vhost matching on the internal listener still works.
#
# Image pin: the image is pulled from ghcr.io/techarohq/anubis (source of
# truth), but the unit runs it under a localhost/-aliased tag: on this host's
# podman 5.7 quadlet path, registry-prefixed refs fail to resolve from local
# storage at container create time ("image not known") even when present; the
# localhost alias resolves (verified live 2026-08-28). v1.27.0 pinned 2026-09-02: --help
# verified on the image itself (cookie-domain, ed25519-private-key-hex,
# cookie-expiration-time default 168h, difficulty default 4); JSON policy
# schema unchanged; X-Real-Ip is now REQUIRED (missing header => HTTP 500) —
# the Caddy chain always sets it (bats seam enforces the header_up line).
# Upgrading = pull new tag, re-tag the localhost alias, restart the unit.
#
# No secrets in this repo. COOKIE_DOMAIN makes the challenge cookie valid for
# all *.franksdank.cloud vhosts: solve the proof-of-work once (e.g. on www)
# and every guarded vhost honors it until expiry (default 168h, aligned with
# authentik's 7-day session) or re-login. ED25519_PRIVATE_KEY_HEX pins the
# JWT signing key (host file /home/dank/Containers/anubis/env, mode 0600,
# gitea-style ${VAR} expansion via the [Service] EnvironmentFile): without
# it every restart invalidates everyone's solved challenges. See
# serverAppConfigs-docs/Infrastructure/Anubis.md.

# The image ships no HEALTHCHECK (distroless ko-build: entrypoint is
# /ko-app/anubis, no shell in the image), so the probe is declared here.
# JSON exec form on purpose: this quadlet generator joins HealthCmd into a
# single \x20-escaped argv element and podman then runs it as shell-form —
# which needs a shell the distroless image does not have. A JSON array is
# passed through verbatim and executes /ko-app/anubis directly.
