This sub-project contains terraform code to understand the concept of multiple built-in functions with the help of resource deployment on Google Cloud Platform.

  • The Terraform language includes a number of built-in functions that you can call to transform and combine values. The Terraform language does not support user-defined functions, and so only the functions built in to the language are available for use.
  • The examples in this directory illustrates the working of few String and Collection functions.

Prerequisites

All the prerequisites mentioned in top level README file must be fulfilled for successful execution of code.

Code Execution

To execute the terraform code, go to command prompt and then run the following commands:

  • [Required] terraform init # To initialize the terraform working directory.
  • [Optional] terraform validate # To validate the terraform configuration.
  • [Optional] terraform fmt # To format the terraform configuration to a canonical format and style.
  • [Optional] terraform plan # To create an execution plan for terraform configuration files.
  • [Required] terraform apply -auto-approve # To execute the actions proposed in a terraform plan to create, update, or destroy infrastructure.
  • [Optional] terraform destroy -auto-approve # To destroy the created infrastructure. Specific resources can be destroyed using resource targetting.
