About this Hands-on Lab

Terraform offers a strong set of features to help optimize your Terraform code. Two really useful features are dynamic blocks, which allow you to generate static repeated blocks within resources in Terraform; and built-in functions, which help you manipulate variables and data to suit your needs and help make your Terraform deployments better automated and more fault resilient.

  2. Switch to the directory where the code is located to perform the remaining tasks.
  3. View the files in the directory.
Examine the Code in the Files
  1. Closely examine the code in the main.tf file.
  2. Review the contents of the variables.tf, script.sh, and outputs.tf files.
Review and Deploy the Terraform Code
  1. Format the code using the terraform fmt command.
  2. Initialize the working directory and download the required providers.
  3. Validate the code using the terraform validate command.
  4. Review the actions that will be performed when you deploy the code using the terraform plan command.
  5. Deploy the code with the terraform apply --auto-approve command.
Test Out the Deployment and Clean Up
