Kubernetes Ephemeral-Storage

#1

Hi,

When running the following command, I can see what is “allocatable” for pods running on the node. Specifically, I’m interested in the “ephemeral-storage” property.
kubectl describe node node-name

  1. Where and how does Kubernetes compute the amount of ephemeral-storage that is allocatable for pods?
  2. What file-systems and directories does it use to determine this value?
  3. How can we ensure there is more allocatable ephemeral-storage for pods?

Thank you.

It’s described in the docs here:
