This sub-project contains terraform code to understand the concept of Custom Conditions and its optional arguments with the help of resource deployment on Google Public Cloud.

  • The check block can validate your infrastructure outside the usual resource lifecycle. Check blocks address a gap between post-apply and functional validation of infrastructure.
  • Check blocks allow you to define custom conditions that execute on every Terraform plan or apply operation without affecting the overall status of an operation.
  • Check blocks execute as the last step of a plan or apply after Terraform has planned or provisioned your infrastructure.

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.
