About this Hands-on Lab

You are a DevOps engineer with an organization that is rapidly adopting Terraform to automate their GCP infrastructure. A team has a CI/CD solution to create new VMs on demand; however, this rapid creation is causing concerns about cloud sprawl. You will need to work with the team to capture information about the infrastructure they are creating with Terraform and generate a report that is available on demand for stakeholders who want to know what is running. To accomplish this, you can make use of Terraform outputs, as well as template files and the local provider.

  • Terraform Outputs: Terraform outputs are values in a Terraform file that are flagged to be available to be consumed by other Terraform objects.
  • Terraform Local Files: Terraform can create files on the host workstation incorporating data from other Terraform objects.
  • Terraform templatefile Function: The Terraform templatefile function allows for the creation of complex formatting specifications for dynamically defined data.
