From the DoK Day EU 2022 (https://youtu.be/Xi-h4XNd5tE)

The container storage interface (CSI) is a contract between different container orchestrators (Kubernetes, Nomad, etc) and storage plugins. This contract is a set of gRPC services for provisioning, utilizing, and snapshotting storage volumes. In this talk, we will focus on one aspect of the CSI spec: Volume Snapshots.

The talk will cover volume snapshots on Kubernetes CSI, with a deep dive on Kubernetes CSI snapshots. A short demo on the basics of the CSI snapshots on Kubernetes will help show how easy it is to start using CSI snapshots.

After covering the basics on both container schedulers, we’ll deep dive into how backup systems can programmatically interact with the Kubernetes CSI snapshots client. This example will be based on Stork, an open-source backup system that has implemented the CSI spec.

I believe this talk will be beneficial to the community because it covers some storage-related topics that have not been covered much in previous conferences. I’m hoping to bring the unique perspective of a Kubernetes CSI and Nomad CSI contributor, while also covering the CSI plugin maintainer and end-user perspective. With this wide audience, many conference attendees will be able to learn about stateful applications, CSI volume snapshots, and developing CSI drivers for any container scheduler.

Grant Griffiths is a core contributor and reviewer for the Kubernetes CSI and SIG Storage communities working at Portworx. For kubernetes-CSI, he helped bring the external-snapshotter to Beta in Kubernetes 1.17 and GA in Kubernetes 1.20, improved support for secrets, release tooling, and fixed various snapshot controller bugs. At Portworx, he works on control plane components such as the CSI Driver, SDK, CLI, and security. Previously, Grant was a Senior Software Engineer at GE Digital where he built Data Services in Go on k8s.

He has given talks at various community conferences:
