This sub-project contains terraform code to understand the concept of conditional expression with the help of resource deployment on Google Cloud Platform.

  • A conditional expression uses the value of a boolean expression to select one of two values.
  • You can create conditions that produce custom error messages for several types of objects in a configuration. For example, you can add a condition to an input variable that checks whether vpc name is of certain length.

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.
