Terraform For Loop – Expression Overview with Examples

In this article, we discuss how to handle 'for loops' in Terraform using meta-arguments such as count and for_each. These constructs can be used for different use cases when you want to repeat a set of actions multiple times. We cover the usage of count, for_each, and for expressions with if clauses. Count is suitable for provisioning identical resources, while for_each is ideal when elements change between instances. The for expression can transform values and be used with an if clause to include or exclude expressions based on a boolean condition.
