You can explicitly reserve resources for non-pod processes by allocating node resources through specifying resources available for scheduling.
To provide more reliable scheduling and minimize node resource overcommitment, each node can reserve a portion of its resources for use by the system daemons that are required to run on your node for your cluster to function.
注意
It is recommended that you reserve resources for incompressible resources such as memory.
For more details, see Allocating Resources for Nodes in the Additional resources section.
