1.3.0    

each time with registry.k8s.io/scheduler-plugins/kube-scheduler:v0.29.7

1. Navigate to Operator Hub
2. Find `Secondary Scheduler Operator for Red Hat OpenShift` `1.3.0`.
3. Install into the `openshift-secondary-scheduler-operato` namespace. `oc adm new-project openshift-secondary-scheduler-operator`
4. When the Operator is installed, create a configmap
```
apiVersion: v1
kind: ConfigMap
metadata:
  name: "secondary-scheduler-config"
  namespace: "openshift-secondary-scheduler-operator" 
data:
  "config.yaml": |
    apiVersion: kubescheduler.config.k8s.io/v1
    kind: KubeSchedulerConfiguration
    leaderElection:
      leaderElect: false
    profiles:
      - schedulerName: secondary-scheduler
        plugins:
          score:
            disabled:
              - name: NodeResourcesBalancedAllocation
              - name: NodeResourcesLeastAllocated
```
5. Create a SecondaryScheduler
```
kind: SecondaryScheduler
apiVersion: operator.openshift.io/v1
metadata:
  name: cluster
  namespace: openshift-secondary-scheduler-operator
spec:
  managementState: Managed
  schedulerConfig: secondary-scheduler-config
  schedulerImage: registry.k8s.io/scheduler-plugins/kube-scheduler:v0.29.7
```
6. You are going to see the pods enter an error state:
```
❯ oc get pods
NAME                                            READY   STATUS    RESTARTS   AGE
secondary-scheduler-545b79fb79-4w5hj            0/1     Error     0          5s
secondary-scheduler-7df94788d4-9n8gz            0/1     Error     0          5s
secondary-scheduler-operator-7474bf64b7-pbmkq   1/1     Running   0          8s
```
7. The logs show the following:
```
❯ oc logs pod/secondary-scheduler-545b79fb79-4w5hj
Error: "kube-scheduler" does not take any arguments, got ["/bin/kube-scheduler"]
```

To fix this, you have to remove the line from .spec.template.spec.containers.args `- /bin/kube-scheduler`
