Use this with a transmission container to get rss feeds into transmission. Can be run straight away without using your own config, by default it will draw from the yify rss feed.
$ docker run --detach \
--link transmission \
--volume /path/to/conf.conf:/etc/transmission-rss.conf \
transmission-rss
In your conf.conf, make sure you keep these values at least:
...
server:
host: transmission
port: <whatever your port is>
...
fork: false
pid_file: false
