Terraform uses HCL, a declarative language that is great for managing the abundance of cloud resources. However, it's declarative nature introduces pain points in automation tasks where procedural languages like PowerShell or Bash perform much better. Provisioners can help with this by automating additional steps when creating or destroying Terraform resources. They can be a powerful tool in the Terraform developer's toolbelt. However, it's important to know from the start that with provisioners comes a cost. Introducing provisioners into Terraform code can cause the code to become complex and introduce other pain points like network or software dependencies in the Terraform configuration. This is why it is important to be aware of how to use provisioners and understand that they should be used as a last resort when developing a solution.

In this lab, you will learn how to create a provisioner to automate additional tasks when creating and destroying an ECR resource.
