Worked on stabilizing Arc-based fleet automation within the Azure/fleet repository by addressing a critical policy issue that blocked fleet agents on Arc clusters. The solution involved updating the ValidatingAdmissionPolicy to include system:serviceaccounts:fleet-system in the allowed groups, thereby unblocking automation and improving the reliability of fleet workflows. This targeted policy fix, implemented using Go and leveraging expertise in Kubernetes admission control and policy management, ensured that fleet agents could operate without interruption. All changes were tracked under a specific commit for traceability, reflecting a methodical approach to collaboration and accountability while focusing on infrastructure stability rather than feature development.
