How to check ephemeral storage that is allocated to EKS node using kubectl command?
I have tried the following: I tried describing the node using kubectl describe node <node-name> which gave lot of info, out of which following is the section related to ephemeral storage.
Capacity:
attachable-volumes-aws-ebs: 25
cpu: 8
ephemeral-storage: 157274092Ki
hugepages-1Gi: 0
hugepages-2Mi: 0
memory: 32042484Ki
pods: 58
Allocatable:
attachable-volumes-aws-ebs: 25
cpu: 7
ephemeral-storage: 142796319300
hugepages-1Gi: 0
hugepages-2Mi: 0
memory: 30916084Ki
pods: 58
Allocated resources:
(Total limits may be over 100 percent, i.e., overcommitted.)
Resource Requests Limits
-------- -------- ------
cpu 1105m (15%) 750m (10%)
memory 3052Mi (10%) 3486Mi (11%)
ephemeral-storage 0 (0%) 0 (0%)
hugepages-1Gi 0 (0%) 0 (0%)
hugepages-2Mi 0 (0%) 0 (0%)
attachable-volumes-aws-ebs 0 0
With those 3 sections, can anyone help me to find the exact ephemeral-storage that is allocated to node?
[In Allocatable section, I do not see units for ephemeral-stoage (142796319300), what is default unit here]
In the output of your kubectl describe node command, the ephemeral-storage value in the Allocatable section is in bytes.
Capacity (total storage): 157274092Ki, is around 150 GiB.
Allocatable (available storage for workloads): 142796319300 bytes, is about 133 GiB.
So basically, your node has 150 GiB of total ephemeral storage, with ~ 133 GiB available for applications.
