tfvars Use Case

[RomeNYRR]

Greetings, 

So far I feel like I have a pretty good handle on Variables (Inputs & Outputs) and how to declare them and interpolate them etc. I typically layout my file structure as follows

main.tf (contains my build and where I define the variables)

outputs.tf (holds my outputs)

variables (declares my variables) 

But what's the best use case for tfvars? Is it simply to pass through sensitive data? Any other use cases? Thanks all

I only use terraform.tfvars for sensitive data - add it to .gitignore and then put AWS API keys in there. That ensures that they don’t end up in my zsh history. Interested to know if there’s any other reasoning for it.

Thanks Mafrosis - pretty much i've been thinking about using it just for that instead of loading keys in my shell env. Any other use cases out there?
