newbie question: How to call string upper/lower in templates

[Alexander Gray II]

I feel silly posting this question, but how do I call string lower or upper in templates?

This doesn't work:

name        = "${lower(${var.database_name}-${var.engine_type}-${var.instance_name}-${var.environment})}"

Nor this:

name        = "${lower({var.database_name}-{var.engine_type}-{var.instance_name}-{var.environment})}"

Nor this:

name        = "${lower(var.database_name-var.engine_type-var.instance_name-var.environment)}"

I'm missing something fundamental here...

Thanks,

Alex

Hey Alex –

Sorry for the delay in response, hopefully you've gotten this sorted, but in case not:

the latter example should do it. I've created this gist to demonstrate:

In short, `${lower(var.key)}` does the trick for me

Hope this helps!
