How to Use the If / Else Statement in Terraform – Examples

In this article, we discuss the use of conditional expressions in Terraform as an alternative to traditional if/else statements found in languages like C#, Python, and Java. Terraform uses ternary operators for conditional logic, with syntax condition ? true_val : false_val. These expressions are particularly useful when used with the count statement to deploy multiple resources based on conditions. We also explore examples of using conditional expressions to define defaults and handle different data types. Additionally, we introduce the coalesce function as an alternative for more complex if/else logic.
