Some updates

[psyciknz]

Not ready to PR (if you're interested), but I've made some updates for this running in Docker. https://github.com/psyciknz/personal-influxdb.git
I've made a docker file and converted a bunch of the config.py code (specifically around the influx server and trakt-tv) to using environment vars.

When Trakt-tv comes back up I'll be able to test it properly. As because they went down, I started looking at a local backup.

Interesting concept.
