As a Terraform project grows, the resource configurations become harder to update and manage. At a certain point, it's beneficial for the team to begin using additional tooling to assist with the management.
Terragrunt is an open-source tool that acts as a thin wrapper around Terraform, enabling configurations to be more in line with DRY. 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 Google Cloud Platform environments while keeping the remote state configuration DRY.
