  5. Keep default settings (install in openshift-gitops-operator namespace)
  6. Click Install again
  7. Wait for the installation to complete (this may take a minute or two)

kind: ClusterRoleBinding
metadata:
  name: argocd-application-controller-cluster-admin
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: openshift-gitops-argocd-application-controller
  namespace: openshift-gitops
