transmission-trackers

This minimal-config docker image will run alongside your transmission installation, check for active torrents, and update their trackers (add additional trackers) using a user-defined tracker-list such as the ones provided by @ngosang at https://github.com/ngosang/trackerslist.

The tracker list will only be downloaded every 8 hours by default (the example list only changes once per day on average) but this frequency can be modified by environment variables.

Torrents are checked every 2 minutes (this can also be customized by environment variables)

If a torrent already has the additional trackers present, no changes will be made. This app will also not make any tracker modifications to torrents flagged as private.

Please note this is a v1 project. While it's been tested on my own setup, there may be issues and configurations that have not been fully tested. Report issues in Issues
