Leveraging the Kubernetes Enqueue Scheduling Plugin for Smarter Workload Placement

Описание: Alessandro Di Stefano and Dennis Gilmore presented at CentOS Connect 2025.

This session highlights the OKD community’s initiative to evolve Kubernetes scheduling into a dynamic, collaborative framework. Building on the experience gained from developing the Multiarch Tuning Operator for OpenShift, the initiative leverages Kubernetes' scheduling gates mechanism to go beyond multi-architecture-aware scheduling. It introduces a framework where multiple controllers can compete to inject augmented information into pod specifications, enabling smarter and more efficient pod placement across Kubernetes clusters.

Rooted in OKD, the upstream distribution of OpenShift, and running on CentOS Stream CoreOS, this effort showcases how the OKD community is driving innovation for scheduling in Kubernetes Clusters. The framework optimizes workload placement while coordinating with descheduling and autoscaling components.

This talk will explore how OKD’s community-driven approach connects observability platforms with Kubernetes’ scheduling ecosystem, closing the feedback loop for improved performance, SLA guarantees, cost savings, and energy efficiency. Attendees will also learn how this framework lays the foundation for a fully distributed, intelligent placement system for Kubernetes workloads.

Join us to discover how the OKD community is extending its vision through CentOS Stream CoreOS, fostering collaboration and innovation to advance Kubernetes scheduling.
