What did you expect to see?

I wanted to see that on nodes with 100% pods usage some pods would be evicted und started on nodes with lower pods usage than 100%

What did you see instead?

Hi @iamdevnull, it looks like your EKS version is 1.21, so the descheduler version 0.25.1 is not supported for your cluster. The latest supported descheduler version for k8s 1.21 is v0.23.0

[iamdevnull]
