Describe the bug

Started to play ArgoCD recently and installed version 2.4.0+91aefab. I'm trying to use PlacementDecision from open-cluster-management as the cluster decision resource, and found that the kind in ConfigMap is actually resource.

my journey of discovering the problem:

At first, I created a ConfigMap

apiVersion: v1
kind: ConfigMap
metadata:
  name: rhacm-placement-cm
  namespace: argocd
data:
  apiVersion: cluster.open-cluster-management.io/v1beta1
  kind: PlacementDecision
  statusListKey: decisions
  matchKey: clusterName

but applicationset controller complain that it does not have permission to list the resource even after I added it into it's Role. I have to change the resource in Role to '*' to work it around.

Then, the applicationset controller complains that it can not find any resource.

I noticed in the controller log, it says,

time="2022-06-23T19:39:37Z" level=info msg="Kind.Group/Version Reference" kind.apiVersion=PlacementDecision.cluster.open-cluster-management.io/v1beta1
time="2022-06-23T19:39:37Z" level=info msg="selection type" listOptions.FieldSelector="metadata.name=turbodecision"
time="2022-06-23T19:39:37Z" level=warning msg="resources were not found" GVK="cluster.open-cluster-management.io/v1beta1, Resource=PlacementDecision"
time="2022-06-23T19:39:37Z" level=error msg="error generating params" error="the server could not find the requested resource" generator="&{0xc0000e8000 0xc0006e6170 0xc0006efe00 argocd 0xc000620300}"

I also found previous log says

time="2022-06-23T18:45:48Z" level=info msg="Kind.Group/Version Reference" kind.apiVersion=PlacementDecision.cluster.open-cluster-management.io/v1beta1
time="2022-06-23T18:45:48Z" level=info msg="selection type" listOptions.FieldSelector="metadata.name=turbodecision"
time="2022-06-23T18:45:48Z" level=warning msg="resources were not found" GVK="cluster.open-cluster-management.io/v1beta1, Resource=PlacementDecision"
time="2022-06-23T18:45:48Z" level=error msg="error generating params" error="PlacementDecision.cluster.open-cluster-management.io \"turbodecision\" is forbidden: User \"system:serviceaccount:argocd:argocd-applicationset-controller\" cannot list resource \"PlacementDecision\" in API group \"cluster.open-cluster-management.io\" in the namespace \"argocd\"" generator="&{0xc0000e8000 0xc0006e6170 0xc0006efe00 argocd 0xc000620300}"

and think it might be a problem with Resource=PlacementDecision

So I changed the configmap to

apiVersion: v1
kind: ConfigMap
metadata:
  name: rhacm-placement-cm
  namespace: argocd
data:
  apiVersion: cluster.open-cluster-management.io/v1beta1
  kind: placementdecisions
  statusListKey: decisions
  matchKey: clusterName

and it worked.

@qiujian16 FYI.

To Reproduce

You can find PlacementDecision CRD here. https://raw.githubusercontent.com/open-cluster-management-io/placement/main/deploy/hub/0000_03_clusters.open-cluster-management.io_placementdecisions.crd.yaml but I think it doesn't really matter. the problem should exist to All CRDs.

Expected behavior

I think the k8s concept is misused here. kind should be PlacementDecision, while resource is placementdecisions. So, either accept the right kind or change the key to resource fixes the confusion.
