Question

Your platform team manages all Google Cloud infrastructure with Terraform. Leadership requires that every resource created across dozens of Terraform configurations carries consistent cost-allocation and environment metadata (for example, cost-center and environment) so that billing exports and organization policy conditions can rely on it. You want to enforce this with minimal per-resource boilerplate and without asking each config author to remember to add the metadata to every resource block. What should you do?

Accepted Answer

Configure default_labels in the google provider block of each configuration so all supported resources automatically inherit the shared labels.

Answer

Add a labels argument manually to every resource block and use a pre-commit hook to reject any resource missing the required keys.

Answer

Create an organization policy constraint that forces all resources to carry the required labels at API admission time.

Answer

Define the metadata once in a local variable and reference it in every resource block via the labels argument.
