Kubernetes

Definition

Kubernetes (K8s) is an open-source container orchestration platform that automates deployment, scaling, and management of containerized applications. For storage, Kubernetes uses the Container Storage Interface (CSI) to dynamically provision Persistent Volumes from external storage systems. StatefulSet workloads (databases, message queues) rely on CSI drivers from vendors like Pure Storage, NetApp, Dell, and open-source solutions like Rook/Ceph and Longhorn.
