Dynamic Provisioning and Capacity-Aware Scheduling for Local Storage

Learn about TopoLVM, a CSI plugin for local storage management in Kubernetes, and discover an upcoming Kubernetes enhancement proposal for capacity-aware scheduling in this 30-minute conference talk. Explore how local storage provides high I/O performance benefits for applications like Elasticsearch and MySQL, while understanding TopoLVM's comprehensive feature set including raw block volumes, resizing, and dynamic provisioning capabilities. Examine the current capacity-aware pod scheduling implementation through scheduler extenders and identify its key limitations: restricted admin installation rights and TopoLVM-specific functionality. Discover the proposed solution through KEP-4049: Storage Capacity Scoring of Nodes for Dynamic Provisioning, which aims to extend TopoLVM's scheduling logic to all CSI drivers without requiring scheduler extenders, making capacity-aware scheduling more accessible and universally applicable across Kubernetes environments.
