Bug 1974414

Hello Vu Dinh,

   one question related to the bug here, do we need to try with the same version of descheduler you  provided at [1] on 4.8 cluster as well ? Also after deleting the csv i do not see any clusterrolebindings of the namespaces are deleted.

[1] docker.io/dinhxuanvu/descheduler-index:v1

Thanks

Hey Rama,

Yes, please use the same version for descheduler operator.

Vu

Moving the bug to verified state as i did not see any CRB getting deleted after deletion of csv. Below are the steps i followed to verify the bug.

steps followed:
===================
1) Install latest 4.8 cluster
2) create namespace called 'openshift-kube-descheduler-operator'
3) create operatorgroup using the yaml below
[knarra@knarra ~]$ cat /tmp/operatorgroup.yaml 
apiVersion: operators.coreos.com/v1
kind: OperatorGroup
metadata:
  name: openshift-kube-descheduler-operator
  namespace: openshift-kube-descheduler-operator
spec:
  targetNamespaces:
    - openshift-kube-descheduler-operator
4) create catalogsource with index image using the yaml below
[knarra@knarra ~]$ cat /tmp/catalogsource.yaml 
apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
  name: qe-app-registry
  namespace: openshift-kube-descheduler-operator
spec:
  sourceType: grpc
  image: docker.io/dinhxuanvu/descheduler-index:v1

5) create subscription using the yaml file below

[knarra@knarra ~]$ cat /tmp/subscription.yaml 
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: cluster-kube-descheduler-operator
  namespace: openshift-kube-descheduler-operator
spec:
  channel: stable
  name: cluster-kube-descheduler-operator
  source: qe-app-registry
  sourceNamespace: openshift-kube-descheduler-operator

Now you can see that csv is in pending state with error "one or more requirements could not be found"

If this bug target release version should be set 4.8.0? Seems the bug is verified on 4.8.0 version

Hello XiuJuan,

  I am not sure if the target version should be set to 4.8.0, this bug was created just for the backporting purpose to 4.6. This was a bug which was seen in ocp4.6 and customer needed a fix as he is not willing to upgrade to 4.7. So we had to backport all the way from 4.9 to 4.6 though this issue does not appear on ocp4.7+. May be Vu Dinh will be a good contact to see if we can set the targetRelease to 4.8.0 ?

Thanks
