exporting a template vs Variables vs other settings

[Jean-Sebastien Vachon]

Hi,

When I export/create a template based on my current flow, is there a way to 
extract the current variables/settings at the same time?

Is there a way of setting these settings (max threads)  and variables through 
the nifi.properties (or other configuration file)?

I'm looking to fully automate the creation of a cluster through Terraform and 
that's about the only missing piece.

Thanks
