PathBackingPurpose
/downloads/incomplete/NFS (sifaka:/volume1/torrents)Active downloads
/downloads/complete/NFS (sifaka:/volume1/torrents)Completed downloads
/config/emptyDir (ephemeral)Transmission settings.json, regenerated on pod start

The watch directory is disabled (watch-dir-enabled: false); torrents are added via RPC (see Kiwix integration below).

kiwix reads from /downloads/complete/ to serve ZIM archives.

Integration with Kiwix

The Kiwix deployment includes a torrent-sync sidecar that:

  1. Reads ZIM torrent list from ConfigMap
  2. Adds missing torrents via RPC
  3. Runs on startup and every 30 minutes

When downloads complete, the zim-watcher CronJob detects new ZIMs and restarts Kiwix.

Monitoring

A transmission-exporter sidecar (image registry.ops.eblu.me/blumeops/transmission-exporter) scrapes the local RPC and exposes Prometheus metrics on port 19091. Uptime is also covered by a blackbox probe in Alloy k8s (Services Health dashboard).

Web UI shows: active/seeding/paused counts, speeds, disk usage.
