TradeIn systemd scrape trigger

Replaces the in-app asyncio scheduler with a systemd timer that calls the admin API every 60s.

Install

Run as root on the VPS after deploy:

cd /opt/gendesign/tradein-mvp/ops/systemd
bash install.sh

install.sh copies the unit files to /etc/systemd/system/, reloads systemd, and enables + starts the timer.

Environment variables

Create /etc/tradein/trigger.env before enabling the timer:

# psycopg v3 connection string (postgresql://... or postgresql+psycopg://...)
TRADEIN_DATABASE_URL=postgresql://tradein:<password>@localhost:5432/tradein

# Admin username from roles.yaml with role=admin — passed as X-Authenticated-User header
TRADEIN_ADMIN_TOKEN=admin

# Backend base URL (no trailing slash). Default: http://localhost:8000
TRADEIN_API_BASE=http://localhost:8000

Diagnostic commands

# Follow live timer logs
journalctl -u tradein-scrape-trigger -f

# List all active timers and next trigger times
systemctl list-timers

# Check timer status
systemctl status tradein-scrape-trigger.timer

# Check last service run
systemctl status tradein-scrape-trigger.service

# Manual one-shot trigger (for testing)
systemctl start tradein-scrape-trigger.service

Notes

• The script uses flock on /var/run/tradein-trigger.lock to prevent overlapping runs if the previous invocation is still running.
• Sources without a dedicated admin endpoint (e.g. rosreestr_dkp_import, listing_source_snapshot) are logged as warnings and skipped. Set SCHEDULER_ENABLE=true in the backend env to handle them via the in-app scheduler.
