About

🐳 This image is based on the wonderful rtorrent-rutorrent Docker image by CrazyMax

The original Docker image is a rTorrent and ruTorrent Docker image based on Alpine Linux.

This image includes the lastest version of Filebot, an so it requires a license (6$/year or 48$ lifetime...a big mac menu for much greater service 😋).

Most of this readme comes from the original repository.

Usage

Docker Compose

Docker compose is the recommended way to run this image. Copy the content of folder examples/compose in /var/rtorrent-rutorrent/ on your host for example. Edit the compose file with your preferences and run the following command:

$ mkdir data downloads passwd
$ chown ${PUID}:${PGID} data downloads passwd
$ docker-compose up -d
$ docker-compose logs -f

Command line

You can also use the following minimal command:

$ mkdir data downloads passwd
$ chown ${PUID}:${PGID} data downloads passwd
$ docker run -d --name rtorrent_rutorrent \
  --ulimit nproc=65535 \
  --ulimit nofile=32000:40000 \
  -p 6881:6881/udp \
  -p 8000:8000 \
  -p 8080:8080 \
  -p 9000:9000 \
  -p 50000:50000 \
  -v $(pwd)/data:/data \
  -v $(pwd)/downloads:/downloads \
  -v $(pwd)/passwd:/passwd \
  crazymax/rtorrent-rutorrent:latest

Notes

XMLRPC through nginx

rTorrent 0.9.7+ has a built-in daemon mode disabling the user interface, so you can only control it via XMLRPC.
Nginx will route XMLRPC requests to rtorrent through port 8000. These requests can be secured with basic authentication through the /passwd/rpc.htpasswd file in which you will need to add a username with his password.
See below to populate this file with a user / password.

WebDAV

WebDAV allows you to retrieve your completed torrent files in /downloads/completed on port 9000.
Like XMLRPC, these requests can be secured with basic authentication through the /passwd/webdav.htpasswd file in which you will need to add a username with his password.
See below to populate this file with a user / password.

Populate .htpasswd files

For ruTorrent basic auth, XMLRPC through nginx and WebDAV on completed downloads, you can populate .htpasswd files with the following command:

docker run --rm -it httpd:2.4-alpine htpasswd -Bbn <username> <password> >> $(pwd)/passwd/webdav.htpasswd

Htpasswd files used:

• rpc.htpasswd: XMLRPC through nginx
• rutorrent.htpasswd: ruTorrent basic auth
• webdav.htpasswd: WebDAV on completed downloads

Boostrap config .rtlocal.rc

When rTorrent is started the bootstrap config /etc/rtorrent/.rtlocal.rc is imported.
This configuration cannot be changed unless you rebuild the image or overwrite these elements in your .rtorrent.rc.
Here are the particular properties of this file:

• system.daemon.set = true: Launcher rTorrent as a daemon
• A config layout for the rTorrent's instance you can use in your .rtorrent.rc:
  • cfg.basedir: Home directory of rtorrent (/data/rtorrent/)
  • cfg.download: Download directory (/downloads/)
  • cfg.download_complete: Completed downloads (/downloads/completed/)
  • cfg.download_temp: Downloads in progress (/downloads/temp/)
  • cfg.logs: Logs directory (/data/rtorrent/log/)
  • cfg.session: Session directory (/data/rtorrent/.session/)
  • cfg.watch: Watch directory for torrents (/data/rtorrent/watch/)
  • cfg.rundir: Runtime data of rtorrent (/var/run/rtorrent/)
• d.data_path: Config var to get the full path of data of a torrent (workaround for the possibly empty d.base_path attribute)
• directory.default.set: Default directory to save the downloaded torrents (cfg.download_temp)
• session.path.set: Default session directory (cfg.session)
• PID file to /var/run/rtorrent/rtorrent.pid
• network.scgi.open_local: SCGI local socket and make it group-writable and secure
• network.port_range.set: Listening port for incoming peer traffic (50000-50000)
• dht.port.set: UDP port to use for DHT (6881)
• log.open_file: Default logging to /data/rtorrent/log/rtorrent.log
  • Log level can be modified with the environment variable RT_LOG_LEVEL
  • rpc_events are logged be default
  • To log executed commands, add the environment variable RT_LOG_EXECUTE
  • To log XMLRPC queries, add the environment variable RT_LOG_XMLRPC

Override or add a ruTorrent plugin/theme

You can add a plugin for ruTorrent in /data/rutorrent/plugins/. If you add a plugin that already exists in ruTorrent, it will be removed from ruTorrent core plugins and yours will be used.
And you can also add a theme in /data/rutorrent/themes/. The same principle as for plugins will be used if you want to override one.

⚠️ Container has to be restarted to propagate changes

Edit a ruTorrent plugin configuration

As you probably know, plugin configuration is not outsourced in ruTorrent. Loading the configuration of a plugin is done via a conf.php file placed at the root of the plugin folder.
To solve this problem with Docker, a special folder has been created in /data/rutorrent/plugins-conf to allow you to configure plugins.
For example to configure the diskspace plugin, you will need to create the /data/rutorrent/plugins-conf/diskspace.php file with your configuration:

<?php

$diskUpdateInterval = 10;	// in seconds
$notifySpaceLimit = 512;	// in Mb
$partitionDirectory = null;	// if null, then we will check rtorrent download directory (or $topDirectory if rtorrent is unavailable)
				// otherwise, set this to the absolute path for checked partition. 

⚠️ Container has to be restarted to propagate changes

Upgrade

To upgrade, pull the newer image and launch the container:

docker-compose pull
docker-compose up -d
