news-cycle.timer runs poll then notify every 15 minutes; news-digest.timer runs the briefing at 08:45 daily. Both enabled and verified: a manual cycle fetched 1047 items, embedded 95 new ones and clustered them in 74s. Units are installed as COPIES rather than symlinks. The previous service's units were symlinked into docs/projects/news/deploy/, and when that repo was renamed to news_triage they became dangling and the timer failed every ten minutes, unnoticed, until this rebuild found it. Copying costs a re-copy after editing; symlinking cost days of silent failure. Deliberate details: the poll ExecStart is `-` prefixed so a failed fetch does not skip notify; RandomizedDelaySec spreads polling off the quarter hour rather than hitting 56 sources at once; the digest is Persistent so a machine that was off at 08:45 still sends rather than skipping the day.

Deploying
This replaces the news-backend service (from ../news_triage) in place: same
host, same vhost, same ntfy topic.
1. Compose — APPLIED 2026-09-08
The news-backend block in ~/compose.yml now reads (snapshot of the previous
file: ~/compose.yml.pre-news-v2):
news-backend:
image: git.rcjohnstone.com/connor/news:latest
restart: unless-stopped
networks:
- internal
environment:
- TZ=America/Louisville
- NEWS_DB=/data/news.db
- NEWS_CONFIG_DIR=/config
- NTFY_URL=${NTFY_URL}
# The old service defaulted to this topic (bin_support.rs:121) rather than
# setting it, so reusing it keeps the existing phone subscription working.
- NTFY_TOPIC=news-triage
- NTFY_USER=${NTFY_USER}
- NTFY_PASS=${NTFY_PASS}
# REQUIRED for feedback buttons. ntfy runs http actions FROM THE PHONE, so
# this must be the public URL, not a container address. Its absence is
# exactly why the previous version's buttons never fired.
- NEWS_API_BASE_URL=https://news.rcjohnstone.com
- NEWS_FEEDBACK_SECRET=${NEWS_FEEDBACK_SECRET}
# One LLM call per day, for the digest prose only.
- NEWS_LITELLM_KEY=${NEWS_LITELLM_KEY}
volumes:
# `U` makes podman chown the volume to the container's uid. The image runs
# as uid 10001, not root, so without it SQLite fails with
# "attempt to write a readonly database".
- ./data/news2:/data:U
# NOT :ro -- the /config page writes back to profile.toml.
- ./config/news2:/config
healthcheck:
# NOT curl: the v0.2 image shipped none, so its healthcheck failed forever
# while the service was fine and `podman ps` reported it unhealthy for days.
test: ["CMD", "python", "-c",
"import urllib.request,sys; sys.exit(0 if urllib.request.urlopen('http://localhost:3000/healthz',timeout=4).status==200 else 1)"]
interval: 60s
timeout: 5s
retries: 3
start_period: 20s
The image is tagged localhost/news-py:latest rather than reusing
git.rcjohnstone.com/connor/news:latest, so the Rust image stays on disk as the
rollback path; the old database at ./data/news/db is likewise untouched.
Rolling back is a two-line edit plus podman-compose up -d news-backend.
Config lives in ~/config/news2/, owned 10001:1000 and group-writable so the
container (uid 10001) can save from the /config page while you can still edit
the files by hand. :U would have worked for the container and locked you out.
The caddy service still bind-mounts ./data/news/web:/srv/news:ro, which is
now unused since the Caddyfile no longer serves a static SPA. Harmless; remove
it whenever the compose file is next touched. A bind-mounted config edit needs
sudo podman restart news-backend; podman-compose up -d will not restart a
container when only a mounted file changed. An environment change does need
the full up -d.
2. Caddy — APPLIED 2026-09-08
Done. The block was moved out of the "Internal only" section into the Public
section (the section headers are load-bearing documentation, and leaving a
public block under an internal header would make the file lie), given a
# ddns: public marker, and reloaded. ddns_update published the A record and
Let's Encrypt issued a cert for the name.
Snapshot of the previous file: ~/Caddyfile.pre-news-public.
Verified after reload: / and /healthz return 403 (Authelia gating), while
/api/feedback/... returns 404 -- a 404 from the OLD backend, which proves
Caddy routed it through without authentication.
# ddns: public
news.rcjohnstone.com {
import secure_headers
import accesslog
# ntfy executes a notification's action buttons FROM THE PHONE, and a native
# app cannot complete an interactive login -- the same reason ntfy, Immich
# and Jellyfin are exempted from the identity gateway on this box. So this
# one path bypasses Authelia. It is safe to: every request carries an HMAC
# signed over (cluster_id, kind), so a leaked URL casts one vote on one
# story rather than acting as a bearer token for the model.
@feedback path /api/feedback/*
handle @feedback {
reverse_proxy news-backend:3000
}
# Everything else is browser-facing, so it goes behind Authelia. Tapping the
# digest notification opens a browser, where an interactive login works.
handle {
import authelia
reverse_proxy news-backend:3000
}
}
The change from the current block is deliberate and worth stating plainly: the
vhost moves from LAN-only (tls internal + import internal, which aborts
anything outside 10.0.0.0/24, 10.0.1.0/24, 10.89.0.0/16) to public. Without
that, feedback buttons fail on cellular and the digest link is unopenable away
from home -- and silent failure there is precisely how the previous version
ended up with 32 labels in a week.
/srv/news/dist is now unused and the root-owned news-update systemd timer
that populated it should be disabled:
sudo systemctl disable --now news-update.timer
Verified after the swap, from the public internet rather than the LAN:
| request | result | meaning |
|---|---|---|
GET / |
403 (Authelia) | browser paths are gated |
POST /api/feedback/.../bogus |
{"error":"bad signature"} |
reaches the app, unauthenticated, and rejects a forgery |
POST /api/feedback/.../<valid HMAC> |
{"ok":true} and a row in feedback |
the loop that never once worked in v0.2 |
3. Scheduling — APPLIED 2026-09-08
Two systemd timers, units in this directory:
| unit | cadence | does |
|---|---|---|
news-cycle.timer |
every 15 min | poll then notify |
news-digest.timer |
daily 08:45 | digest |
sudo cp deploy/news-*.service deploy/news-*.timer /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable --now news-cycle.timer news-digest.timer
Copy the units, do not symlink them. The previous service's units were
symlinks into docs/projects/news/deploy/, and when that repo was renamed to
news_triage they became dangling and the timer failed every ten minutes,
unnoticed, for days. The cost of copying is remembering to re-copy after editing
a unit here; the cost of symlinking is a silent failure the next time a
directory moves.
Design notes:
news-cycle.servicehas twoExecStartlines and the first is prefixed-, so a failed fetch does not skipnotify-- there may still be ripe clusters from an earlier cycle worth sending.RandomizedDelaySec=90on the cycle: feeds get polled by everyone on the quarter hour, and this both spreads that load and avoids hitting all 56 sources at the same instant.Persistent=trueon the digest, so a machine that was off at 08:45 still sends the briefing on the next boot rather than silently skipping a day.TimeoutStartSec=20minon the cycle: a cold start embeds the whole backlog at ~11 items/sec. Steady state is far quicker -- a real incremental cycle measured 74s for 95 new items.
Reading the logs is noisier than it should be, because podman writes its own container-exec events into the same unit journal:
journalctl -u news-cycle -o cat | grep -vE '^[0-9]{4}-[0-9]{2}-[0-9]{2} .* container '
4. Verifying it actually works
podman exec news-backend python -m news.cli poll # fetch, embed, cluster
podman exec news-backend python -m news.cli simulate # what WOULD be sent
podman exec news-backend python -m news.cli notify --dry-run
Then the one test that matters, because it is the loop that was broken before:
send a real notification, tap a feedback button on the phone, and confirm a
row lands in feedback:
podman exec news-backend python -c \
"import sqlite3;print(sqlite3.connect('/data/news.db').execute('select * from feedback').fetchall())"
