Intro

While studying for the Terraform Certification I struggled quite a bit with all the weird error messages from Terraform when working with Lists and Maps.

Therefore, this article is for myself to get a clear picture of Lists and Maps in Terraform. Maybe others also see some help in this.

Setup

Create a directory in which we put a number of tf files.

Only main.tf files will be used. No providers and only a couple of modules.

Also, have Terraform utility (1.5.4 in this article) installed.
