Kubernetes emptyDir: Temporary Storage for Pods

Imagine a scratchpad your application can use while it’s running. That’s what emptyDir offers. When a pod is scheduled on a node, Kubernetes creates an emptyDir volume — a blank directory — tied to that pod's lifecycle. It’s perfect for things like caching, temporary files, or intermediary processing results. As soon as the pod is removed from the node (because it’s deleted or moved), this directory and its contents are gone. So think of it as ephemeral storage: useful, fast, but not meant to be permanent.
