Deleting Terraform Resources

Terraform is a powerful tool for creating and managing infrastructure as code. It can be used to create a wide variety of resources, including EC2 instances, S3 buckets, and Cognito user pools.

Once you have created resources with Terraform, you can easily delete them using the terraform destroy command. This command will delete all of the resources that were created by the Terraform configuration file.

Do you really want to destroy all resources?
  Terraform will destroy all your managed infrastructure, as shown above.
  There is no undo. Only 'yes' will be accepted to confirm.

  Enter a value: yes
