Backend Config in Chapter 4: Modules about terraform-up-and-running-code HOT 3 CLOSED

One of the limitations of Terraform is that the backend config blocks do not support ANY variables or interpolation. That's why they are hard-coded and copy/pasted in most places in the book.

Terraform does not natively offer any way to keep the backend config DRY. You can extra some of the pieces into reusable files using partial configuration, but the key parameter must be specified manually for every single module, which is a very tedious and error-prone process. Another option is to use a tool like Terragrunt, which has first-class features for keeping your backend configuration DRY. Both options are covered in the book and code examples in this repo!

Ah, alright. That explains it nicely. (Guess I got a bit ahead of myself there.)

Also, just wanted to mention that I'm enjoying the book plenty. It's helped me understand a lot about Terraform and its usage patterns. Thank you for that.
