Description RamaKasturi 2020-03-26 06:17:15 UTC
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):

How reproducible:

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

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"

Switching this to 4.5, please verify it against master with a manual deployment (these steps should be sufficient now: https://github.com/openshift/cluster-kube-descheduler-operator#quick-development, no need to go through the index image method if you don't want to)

That will allow https://bugzilla.redhat.com/show_bug.cgi?id=1817318 to be backported to 4.4 in https://github.com/openshift/cluster-kube-descheduler-operator/pull/104
