## Automatic Resource Reservation Calculation
While manually specifying resource reservations for kube and system daemons works, Kubespray offers a more convenient approach. You can set the `kube_enable_auto_reserved_resources` flag to `true`. This instructs Kubespray to automatically calculate appropriate resource reservations for `kube_[master]_cpu_reserved` and `kube_[master]_memory_reserved` based on your host size. This eliminates the need for manual configuration, simplifying the process.
