  # This annotation lowers the possibility that kube-proxy gets evicted when the
  # node is under memory pressure, and prioritizes it for admission, even if
  # the node is under memory pressure.
  # Note that kube-proxy runs as a static pod so this annotation does NOT have
  # any effect on rescheduler (default scheduler and rescheduler are not
  # involved in scheduling kube-proxy).
