Kubernetes Ephemeral-Storage

General Discussions
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:

Hi,

Could you help me to how to monitor ephemeral storage used by PODs. Containers and Nodes? Which 3PP/K8s process do I need to monitor to get such metrics?

Many Thanks,
Teja

I’m actually looking for the same. Shouldn’t there be a way to describe our output the total ephemeral storage as determined by k8s when its calculating how much a pod or container is using?
