Worked on the GoogleCloudPlatform/cloud-foundation-fabric repository to deliver a new Cloud SQL Data API access control attribute within the cloudsql-instance module. This feature enables explicit governance over Cloud SQL Data API access, supporting enhanced security and compliance requirements. The implementation involved extending Terraform code to introduce the data_api_access variable, complete with validation logic and default handling to maintain backward compatibility. Comprehensive updates were made to automated tests and documentation to ensure correct integration and usage. Leveraging skills in cloud computing, infrastructure as code, and Terraform, the work focused on robust module design and clear user guidance without introducing breaking changes.
