Understanding Kubernetes Storage: Getting in Deep by Writing a CSI Driver
Gerry Seidman, AuriStor
Understanding the many Kubernetes storage ‘objects’ along with their not-always-obvious interaction and life-cycles can be daunting (Volumes, Persistent Volumes, Persistent Volume Claims, Volume Attachments, Storage Classes, Volume Snapshots, CSIDriver, CSINode, oh my...)
Perhaps the best ways to gleen a deep understand of these storage objects and how storage-related scheduling works in Kubernetes is to write a Container Storage Initiative (CSI) driver. While most of us will never need to write a CSI driver, in this session we will make storage with Kubernetes more accessible by exploring it from an inside-out approach learned by writing a CSI Driver.
In this session you will obtain an understanding of:
* How Kubernetes 'Volumes' relate to mounted storage available from within containers
* The Kubernetes Declarative Model
* The many Kubernetes Storage Objects
* Kubernetes Scheduling and how it is influenced by storage object
* How Kubernetes controllers move the storage objects through their life-cycles
* What is the role and responsibility of a storage type specific CSI Driver
* What are the roles and responsibilities of CSI support ‘Side-Cars’
* Putting it all together and relating this all back to how to write a CSI Driver
