Docker env and config options

[seanyar]

Great idea. Trying this out now.

The readme.md mentions the script runs automatically every 5 min. However, there is a sleeptime variable being set in the docker environment. Does the env variable also control how often the script runs?

The number of cores used is also one of the env variables. However, the readme.md suggests passing it as an argument to the script under advanced options. Do both work the same way? If so, you may want to update the documentation.
