The minimum set of methods a provider needs to implement for a resource is: Create, This lifecycle option prevents Terraform from accidentally removing critical resources. It provides a way to specify additional behavior that affects how Terraform handles changes to a Terraform is a potent tool for automating infrastructure management. ; We added the embedded original-resource to save the imported state so it can be restored when the resource is deleted from the Terraform state. In this tutorial, you will use Terraform to provision and manage an Auto Scaling group and learn how Terraform configuration supports the dynamic aspects of the resource.
