The previous commit renamed the record list to 'rows' but missed the loop in load_ignored_keywords, leaving a bare 'j' -> 'tick error: name j is not defined' every tick. The loop died, health.json went ok:false, the container reported unhealthy, and alert_on_health fired against a live failure. - fix the stale reference - use real emoji instead of literal backslash escapes in alert text - test: exercise the real loaders end-to-end against a fake NocoDB so a missed rename is caught (mutation-verified: reintroducing the bug fails 3 checks)
carousell-monitor
Watches Carousell search pages (sorted by recent) for new listings, archives every listing to a NocoDB base (with image URL + thumbnail), and alerts Telegram.
How it works
monitor.pyruns in a Docker container on DSM, self-bootstrapping its NocoDB schema (Listings+Settings+IgnoredSellers+IgnoredKeywordstables) and looping forever.- Every
TICK_SECONDSit reads the watch list from the Settings table and polls each enabled watch's URL on its owncheck_interval_minutes. - Dedupe key =
product_url(param-less listing URL). First run per watch = seed archive only (no Telegram). After that, new listings are archived and alerted as"<title>: N new listings". - The container marks itself unhealthy (Docker healthcheck) if a tick fails to extract / gets rate-limited / crashes.
Schema
Listings — product_url (unique), title, price (numeric), condition
(SingleSelect), image_url, image (Attachment → thumbnail), seller_name,
seller_url, search_title, search_url, listed_at, first_seen_at,
notified, skip_notify.
Settings — title, url, enabled, notify, check_interval_minutes,
last_checked_at. Add/remove watches here from the NocoDB UI; no redeploy needed.
IgnoredSellers — seller_name. Add/remove sellers here to suppress Telegram
alerts for their listings (still archived, marked skip_notify=true).
IgnoredKeywords — watch (Link → Settings) + keyword. Per-watch title
blocklist: pick the watch from a dropdown, add one keyword per row. A keyword only
applies to listings from the linked watch; case-insensitive substring match against
the title. Still archived.
Run
# local (against LAN NocoDB)
NOCODB_URL=http://192.168.137.2:10380 \
NOCODB_TOKEN=... TELEGRAM_BOT_TOKEN=... TELEGRAM_CHAT_ID=... \
python monitor.py
# docker
docker build -t hoelee/carousell-monitor:latest .
docker compose up -d
Deploy (DSM via Portainer stack 240)
Private build — no registry. The container is owned by Portainer stack 240
(standalone; compose + build context at /volume1/docker/portainer/compose/240/
on DSM), deployed with secrets passed as stack environment variables.
# on DSM — rebuild the image only when monitor.py / Dockerfile changed
sudo /usr/local/bin/docker build -t carousell-monitor:latest \
/volume1/docker/portainer/compose/240
Then update stack 240 via the Portainer API (PUT /api/stacks/240?endpointId=2,
repo compose as stackFileContent + current env array — see portainer-api
skill; ⚠ never echo masked *** env values back). The old
/volume1/docker/carousell-monitor dir is legacy — do not compose up there.
