   control-plane=mac-controller-manager | awk '{print $1}')"

  2. Set the KMP_NAME environment variable:

    $ export KMP_NAME="$(kubectl get pod -A --no-headers -l \
   control-plane=mac-controller-manager | awk '{print $2}')"

  3. Obtain the KubeMacPool-manager pod details:

    $ kubectl describe pod -n $KMP_NAMESPACE $KMP_NAME
