What will happen when you run terraform destroy without any flags after successfully creating resources including a load balancer?

When you run terraform destroy without any flags after successfully creating resources, Terraform will prompt for confirmation to destroy all infrastructure managed by the current configuration. This is a designed safety measure that ensures users consciously decide to remove resources, rather than accidentally deleting critical infrastructure.

The command's default behavior is to attempt to delete all resources tracked in the Terraform state file, which includes the load balancer and any other resources that were created. The confirmation prompt allows the user to review the impending destruction and make an informed decision.

This behavior underscores the importance of reviewing changes in Terraform, as it operates based on the defined configurations and state, making it crucial to confirm before execution to prevent unintended data loss or service interruption.
