Across Kubernetes Namespace Boundaries: Your Volumes Can Be Shared Now!

This talk addresses the challenge of sharing persistent volumes (PVCs) and volume snapshots across Kubernetes namespaces. Previously, data sources were restricted to the same namespace, hindering use cases like copying production data to development environments or sharing golden images. The presentation explains the new cross-namespace volume data source feature in Kubernetes 1.26, demonstrating how it works with demos and detailing the use of the ReferenceGrant API to manage access control.
