export TF_VAR_region=us-west-1

export TF_VAR_ami=ami-049d8641

export TF_VAR_alist='[1,2,3]'

export TF_VAR_amap='{ foo = 'bar', baz = 'qux' }'

Nah, I don't think 'TF_ENV_VAR' is the right answer here. That just sounds a bit too specific, you know? 'TF_VAR' is the standard, and that's what I'm going with.

Hmm, I'm not so sure about that. What about 'TF_ENV_VAR'? Doesn't that also sound like it could be a valid option? I mean, it's specifically for environment variables, right?

Yeah, I agree with Marla. 'TF_VAR' is the way to go. It's the standard format that Terraform expects for environment variables. If you try to use anything else, it's just not gonna work.

Ooh, I've seen this question before! It's all about those tricky environment variables. Let's see, the correct prefix has to be 'TF_VAR', right? That's the one that Terraform uses to set variables.
