This is a rtorrent-rutorrent combo created by crazy-max but with some changes that make the build more applicable to use with PVRs such as Sonarr, Lidarr, etc.

The sources can be downloaded from the Wizardry and Steamworks Subversion:

• https://svn.grimore.org/docker/build/docker-rtorrent-rutorrent/

The usage is documented on the original repository page by crazy-max and can be found on github.

The following changes have been made to the current crazy-max releases:

• rTorrent has been downgraded to 0.9.8 and the configuration adapted to match,
• temp and complete folders have both been remapped into downloads for compatibility with PVRs

Because the Dockerfile needs additional components, the build environment can be downloaded via the SVN and the following is just a patch in order to be able to inspect the changes.
