Use emptyDir volumes to share data between containers, understand the volume lifecycle across container restarts and pod deletion, and explore memory-backed ephemeral storage.
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.
Mount configuration and secrets into a single directory path using advanced Kubernetes volume techniques.
Create a PersistentVolume with hostPath, bind it to a PersistentVolumeClaim, and mount it in a Deployment. This demonstrates storage management in Kubernetes.
