Description

As Terraform configurations grow to be large and complex, the code becomes harder to manage and make changes. Terragrunt is an open-source tool that acts as a thin wrapper around Terraform, enabling configurations to be "DRYer". DRY is a popular software development practice that stands for "Don't Repeat Yourself," which means don't re-use the same software pattern, avoiding redundancy. Terragrunt adds a feature that allows Terraform remote state configurations to be defined once in code and re-used throughout multiple Terraform projects.

In this lab, you will use Terragrunt to deploy a Terraform configuration in separate environments while keeping the remote state configuration DRY.
