This document discusses Kubestr, a set of tools to help debug, validate, and evaluate storage in Kubernetes clusters. It allows users to identify available storage options, validate storage configurations, evaluate performance using benchmarks, and browse the contents of persistent volumes. The presentation provides an overview of common storage issues Kubestr aims to address, a demonstration of its features, and a call for users to try the tools and provide feedback.
