A RoleBinding can also reference a ClusterRole to grant the permissions defined in that ClusterRole to resources inside the RoleBinding's namespace. This kind of reference lets you define a set of common roles across your cluster, then reuse them within multiple namespaces.

For instance, even though the following RoleBinding refers to a ClusterRole, "dave" (the subject, case sensitive) will only be able to read Secrets in the "development" namespace, because the RoleBinding's namespace (in its metadata) is "development".

  clientset, err := kubernetes.NewForConfig(&rest.Config{
    Host:        "URL",
    BearerToken: "SA token",
  })
  if err != nil {
    panic(err.Error())
  }
