Description Jan Chaloupka 2022-05-27 11:40:32 UTC

https://issues.redhat.com/browse/WRKLDS-300

The Descheduler Operator should provide the ability to include/exclude certain namespaces to the user. It currently has hardcoded logic to exclude all namespaces prefixed with `openshift-` or `kube-`. Customers would like the ability to provide a similar pattern, or specific list.

This would be difficult to implement on a per-profile basis without considerable refactoring of the operator CRD, so it should be implemented as a top-level option.

Verified bug with the paylaod below and i see that it works fine, so moving the bug to verified state.

[knarra@knarra OpenShift]$ oc get csv -n openshift-kube-descheduler-operator
NAME                                                 DISPLAY                            VERSION               REPLACES   PHASE
clusterkubedescheduleroperator.4.11.0-202206030929   Kube Descheduler Operator          4.11.0-202206030929              Succeeded

[knarra@knarra OpenShift]$ oc get clusterversion
NAME      VERSION                              AVAILABLE   PROGRESSING   SINCE   STATUS
version   4.11.0-0.nightly-2022-06-06-025509   True        False         13h     Cluster version is 4.11.0-0.nightly-2022-06-06-025509

Below cases were tested:
==========================
1) Enable both include/exclude namespaces and verify that descheduler operator does not allow enabling both at the same time
2) Enable excluded namespaces and verify that pods does not get evicted from the excluded namespace even if they meet eviction criteria
3) Enable included namespaces and verified that pod gets evicted from the included namespaces if they meet eviction criteria.
