Whatever is in the default kustomize example.

            - "--policy-config-file"
            - "/policy-dir/policy.yaml"
            - "--v"
            - "3"

Thanks for reporting this issue @armenr We will get this included as part of v0.28.0 release which is right around the corner.

Meanwhile, you should be able to add this change locally: https://github.com/kubernetes-sigs/descheduler/pull/1207/files
