Terraform’s homemade File function Reads a text file and injects the contents as a string. The .tpl extension Makes templates that map to variables of the main code. If you need to have, for example, EC2 instanc...

Think about using for_each - This is often used to make individual resources with a value to iterate over. Is This a Dynamic Block?
