Just a small Docker container that runs SickRage!
You can run this right out of the box with no adjustments.
$ docker run -d -P quay.io/albertrdixon/sickrage
If you want your config changes and data to persist (and of course you do), then run like so:
$ docker run -d -P -v /path/to/sickrage/data:/data quay.io/albertrdixon/sickrage
Simple!
/sickrage - Application is installed to this path
/data - Sickrage data directory (mount a volume here to persist Sickrage data)
Note: I would also mount /etc/localtime in the container as read-only (-v /etc/localtime:/etc/localtime:ro)
