Brian Nutt developed a new runProgram option for the Pulumi Automation SDK in the pulumi/pulumi repository, enabling users to control execution of the workspace program during preview and up operations. By implementing this feature across Go, Python, and TypeScript, Brian ensured cross-language consistency and improved automation workflows for infrastructure updates. The technical approach focused on API development and cloud infrastructure, allowing users to preview changes without executing the workspace program and to run it when desired. This work enhanced deployment safety and flexibility, providing a smoother developer experience and addressing the need for more controlled, reliable infrastructure automation processes.
