Terraform Functions can be used in an application to dynamically retrieve or manipulate the configuration values of your cloud resources.

Use cases of Terraform functions include:

  • Capturing or displaying timestamps
  • Encoding or decoding sensitive information
  • Referencing elements from a map or list
  • Reading the contents of a configuration file

Terraform functions, along with input variables, allow developers to abstract specific values from their infrastructure as code as they strive to create resource definitions that are entirely reusable.

In this lab, you will work with the Terraform console to evaluate the various built-in function types. You will also incorporate a common Terraform function into an application to deploy an EC2 instance.
