A 'caddy reload' delivered over the admin API cannot apply a config
that disables the admin API -- the fix cannot ride the API it is meant
to enable (2026-08-22: admin off sat in the running config across
deploys). Track the reload result; on failure, restart the container
so it reads the rendered file on start.
The Caddyfile had 'admin off', which disables Caddy's config file
watcher. Rendered Caddyfile changes never loaded until the container
was recreated, so the double-hash basicauth fix sat on disk unapplied
across deploys (2026-08-22). Admin binds to 127.0.0.1:2019 inside the
container and the port is unpublished, so nothing outside reaches it.
deploy.sh now issues an explicit 'caddy reload' (retry loop) after
'up -d', with the file watcher as backstop.
basicauth (2026-08-22 incident):
- the Caddyfile template carried its own $2a$14$ prefix and deploy.sh
substituted the full hash (prefix included), rendering an invalid
double-prefixed hash. Every basicauth vhost rejected every password
with 401 and Caddy logged nothing.
- template is now a bare REPLACE_WITH_HASH token; tests pin the render
contract (no prefix in template; rendered line is exactly 'dank <hash>').
open-webui (2026-08-22 incident):
- its slirp4netns helper process died, leaving the container running
with only 'lo' in its netns: port 3005 accepted TCP and reset every
request, so chat served empty responses for ~2 days, unlogged.
- move to a pinned bridge network (systemd-open-webui, 10.89.3.0/24,
gw 10.89.3.1) — no per-container helper to die.
- LLM endpoint reached via the gateway (host.containers.internal is
slirp-only): OPENAI_API_BASE_URL=http://10.89.3.1:52625.
- add a quadlet healthcheck: /health (app) + non-loopback interface
(network liveness; the dead-tap state leaves only 'lo').
- deploy script now copies the .network file too.
- docs updated (OpenWebUI History section, Caddy basic-auth contract).
