Andrej worked on the openshift/assisted-service repository, where he developed an explicit control plane node count configuration for cluster installations. By introducing the control_plane_count field in the InstallCmdRequest API and deprecating the previous high_availability_mode, he enabled more predictable and accurate cluster deployments. This change improved deployment correctness and reduced the risk of misconfiguration during automated installs. Andrej’s work involved backend development and API design, utilizing Go and YAML to implement the new configuration. The feature addressed a specific need for clarity in cluster provisioning, demonstrating a focused and well-scoped engineering effort over the course of the month.
