How can you utilize Terragrunt to create a Resource Group and Key Vault on Azure while adhering to the DRY (Don't Repeat Yourself) principle?

edit

To utilize Terragrunt to create a Resource Group and Key Vault on Azure while adhering to the DRY principle, you can follow these steps:

1. Create a module that defines the resource group and key vault resources. This module should take in variables for the resource group name, key vault name, and any other necessary configuration options.

2. Use Terragrunt to create a configuration file that defines the module and sets the variables required for the resource group and key vault resources.

3. Store the configuration file in a separate Git repository that Terragrunt can reference as a dependency.

4. Reference the Git repository as a module in your main Terraform configuration. This will allow you to easily create multiple instances of the resource group and key vault without duplicating the module code.

5. Use Terragrunt to apply the module configuration across multiple environments, such as dev, test, and prod.

By following these steps, you can utilize Terragrunt and the DRY principle to create resource groups and key vaults on Azure quickly and efficiently, while avoiding duplication of code and configuration.
