CSI Driver and FUSE Drivers: Kubernetes Object Storage Solution for AI/ML Data Portability

Explore a Kubernetes object storage solution for AI/ML data portability in this conference talk. Learn how to address the challenges of using object storage with Kubernetes for AI/ML workloads. Discover a novel approach that combines CSI drivers with FUSE drivers to create a Kubernetes volume interface for object storage. Understand the three key requirements for practical production use of FUSE as a Kubernetes volume layer, including matching FUSE process lifetime to Pod lifetime, managing resource consumption, and handling workload-specific credentials. Examine a solution based on sidecar injection that leverages kernel cross-process file descriptor transfer to effectively separate privileges, authentication, workload lifecycle, and resource usage. Gain insights into how this solution can be adopted by any FUSE volume, potentially revolutionizing object storage integration in Kubernetes environments for AI/ML applications.
