# Quadlet unit: Hermex webui (Hermex) container (rootless, boot-persistent).
#
# Install path on dankclaw: ~/.config/containers/systemd/hermes-webui.container
# Unit name: hermes-webui.service (container name: hermes-webui)
#
# Runs the open-source hermes-webui (github.com/nesquena/hermes-webui) in
# foreground mode: bootstrap.py creates .venv inside the mounted checkout,
# installs WebUI + agent deps, then execs server.py as a single foreground
# process. It reads HERMES_HOME=/data, so it drives the SAME agent state
# (memory, skills, sessions) as the gateway container.
#
# Host networking on purpose: the agent's chrome-devtools MCP client spawns
# npx chrome-devtools-mcp with --browserUrl=http://127.0.0.1:9222, and the CDP
# daemon binds loopback-only in the host network namespace (see
# chrome-devtools-protocol.container). Only processes sharing that namespace
# can drive the browser; a bridge-network client could not reach it at all.
# The server binds 0.0.0.0:8787 of the host netns, and that is deliberate:
# this unit is host-networked (the CDP daemon above needs a shared loopback), so
# Caddy cannot reach it by container name and fronts the vhost
# hermes.franksdank.cloud with `reverse_proxy host.containers.internal:8787`
# (netavark's host address, 169.254.1.2) — not the host LAN IP, which Caddy's
# bridge netns cannot reach for a bare host-netns bind; the measured asymmetry
# with published ports is recorded in the hermes block of dankclaw/Caddyfile.
# A loopback bind was tried on 2026-09-16 for a tighter posture and broke that
# vhost, because a bind is also the only way an off-host process can reach a
# host-networked container: the LAN address and the tunnel's localhost hop are
# both served by the wildcard, and a loopback-only bind serves only the latter.
# Controls are the auth chain in front of the vhost plus the password.
