= About the Node Tuning Operator
|
|
|
|
The Node Tuning Operator helps you manage node-level tuning by orchestrating the
|
|
tuned daemon. The majority of high-performance applications require some level of
|
|
kernel tuning. The Node Tuning Operator provides a unified management interface
|
|
to users of node-level sysctls and more flexibility to add custom tuning, which
|
|
is currently a Technology Preview feature, specified by user needs. The Operator
|
|
manages the containerized tuned daemon for {product-title} as a Kubernetes
|
|
DaemonSet. It ensures the custom tuning specification is passed to all
|
|
containerized tuned daemons running in the cluster in the format that the
|
|
daemons understand. The daemons run on all nodes in the cluster, one per node.
|
|
|
|
The Node Tuning Operator is part of a standard {product-title} installation in
|
|
version 4.1 and later.
