Fill a Gap of Kubernetes: IO Resource Scheduling and Isolation

summary
Describes adding disk I/O scheduling and isolation to Kubernetes by letting users declare per-container disk I/O requests in the Pod spec and using a new scheduler plugin to place Pods on nodes that can meet those guarantees. It collects real-time per-workload disk I/O utilization and node-level disk saturation, feeds that back to the Kubernetes control plane to optimize placement, and dynamically tightens best-effort workloads’ I/O boundaries to free I/O for guaranteed workloads; a demo is included.
