• RW compute nodes in Kubernetes do not necessarily require an ephemeral volume mount, but it can be beneficial for managing data and avoiding disk pressure issues.
• Ephemeral volume mounts provide temporary storage for pods and can be useful for storing data that does not need to persist beyond the pod's lifecycle.
• It's important to review the documentation and ensure that the storage requirements for your compute nodes are properly configured to avoid disk pressure and data loss.

Example:

spec:
  containers:
  - name: my-container
    image: my-image
    volumeMounts:
    - name: ephemeral-storage
      mountPath: /data
  volumes:
  - name: ephemeral-storage
    emptyDir: {}
