Description RamaKasturi 2020-03-26 06:19:29 UTC

+++ This bug was initially created as a clone of Bug #1817316 +++

Description of problem:
I see that the descheduler only honors short hand strategy names like duplicates, interpodaffinity, nodetaints etc where as it should also honor strategies "RemoveDuplicates" , RemovePodsViolatingInterPodAntiAffinity etc.

Version-Release number of selected component (if applicable):
4.4.0-0.nightly-2020-03-24-101858

How reproducible:
Always

Steps to Reproduce:
1. Install descheduler operator
2. Now set the strategy as "RemoveDuplicates"
3.

Actual results:
Descheduler does not create any kubedescheduler cluster object with this strategy and it gives below error.
and error is seen in the operator logs E0324 16:12:46.123566       1 target_config_reconciler.go:297] key failed with : expected one of the duplicates,interpodantiaffinity,lownodeutilization,nodeaffinity,nodetaints to be enabled but found following invalid strategies RemoveDuplicates

Expected results:
Descheduler should honor the startegy name "RemoveDuplicates"

Additional info:

This bug needs to be fixed for 4.4 as descheduler should work with both short hand and actual strategy names.
