# Phase 2 - Github Action

The code block defines a job named "destroy" which runs on an Ubuntu machine. The job depends on the successful completion of the "apply" job because of the "needs" key. It has a condition defined by the "if" key that checks the value of the "prompt" input that was passed during the workflow dispatch event. If the value of "prompt" is equal to "yes", then the job will be executed, otherwise it will be skipped.

The job consists of several steps, which are executed sequentially:

1. Checkout code: This step checks out the code from the repository using the actions/checkout action.
2. Set up Terraform: This step sets up Terraform on the machine and configures the AWS access key ID and secret access key using the hashicorp/setup-terraform action.
3. Download Terraform state: This step downloads the Terraform state file that was saved during the "apply" job using the actions/download-artifact action.
4. Terraform Init: This step initializes Terraform on the machine.
5. Terraform Destroy: This step destroys the infrastructure that was created by the "apply" job using the terraform destroy command. The -auto-approve flag is used to skip the confirmation prompt.
6. Save Terraform State: This step saves the Terraform state file after the destruction of infrastructure using the actions/upload-artifact action.
