January 2026 monthly summary for stolostron/ocm focused on stabilizing cluster management workflows and reducing operational risk in multi-cluster environments. Delivered a critical bug fix to RBAC cleanup in managed clusters when hubAcceptsClient is false, including robust error handling around the removeClusterRbac call in the controller synchronization path and ensuring work rolebindings are deleted when no longer needed. This reduces the chance of orphaned RBAC objects and cleanup failures during reconciliation, enhancing overall reliability of the control plane. Skills demonstrated include Go, Kubernetes RBAC, controller-runtime patterns, and robust error handling. Business impact: higher stability of cluster management, fewer manual remediation efforts, and smoother operations during multi-cluster deployments.
