Kubernetes Fundamentals, Part 5: Working with Kubernetes Volumes

Kubernetes faces challenges with container storage due to the temporary nature of file systems in containers, which lose changes upon shutdown. To address this, Kubernetes provides two key storage solutions: volumes and persistent volumes. Volumes allow shared storage within a Pod, accessible by all its containers, but are tied to the Pod's lifecycle, resetting upon restart. Persistent volumes, however, exist at the cluster level, independent of individual Pods, allowing data persistence across Pod restarts and sharing among multiple Pods. Volumes require specification of "volumeMounts" for access within containers, while persistent volumes are provisioned either statically or dynamically and require a PersistentVolumeClaim to allocate storage. These storage solutions enable data sharing and persistence within Kubernetes environments, catering to different application needs and providing flexibility in managing storage resources.
