# Deploying

This replaces the `news-backend` service (from `../news_triage`) in place: same
host, same vhost, same ntfy topic.

## 1. Compose

Replace the `news-backend` block in `~/compose.yml`:

```yaml
  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
      - ./config/news2:/config:ro
    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
```

Copy `profile/*.toml` to `~/config/news2/`. 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:

```sh
sudo systemctl disable --now news-update.timer
```

**Current state:** the vhost is public and correctly gated, but `news-backend`
is still the old Rust service, which no longer has its SPA served by Caddy. So
`https://news.rcjohnstone.com/` is a 404 behind the login until the compose
service is switched to this image. Notifications from the old service are
unaffected.

## 3. Scheduling

```
*/15 * * * *  podman exec news-backend python -m news.cli poll
*/20 * * * *  podman exec news-backend python -m news.cli notify
45   8 * * *  podman exec news-backend python -m news.cli digest
```

## 4. Verifying it actually works

```sh
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`:

```sh
podman exec news-backend python -c \
  "import sqlite3;print(sqlite3.connect('/data/news.db').execute('select * from feedback').fetchall())"
```
