Challenge

Configure a Memory-Backed emptyDir Volume with a Size Limit

A Deployment is using a disk-backed emptyDir volume. Convert it to a memory-backed tmpfs volume for better performance — but make sure to set a size limit to prevent the Pod from exhausting the node's RAM.

Challenge

Kubernetes - emptyDir Volumes: Sharing, Lifecycle, and Memory-Backed Storage

Use emptyDir volumes to share data between containers, understand the volume lifecycle across container restarts and pod deletion, and explore memory-backed ephemeral storage.
