== Purpose
|
|
endif::operators[]
|
|
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 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.
|
|
|
|
Node-level settings applied by the containerized Tuned daemon are rolled back on
|
|
an event that triggers a profile change or when the containerized Tuned daemon
|
|
is terminated gracefully by receiving and handling a termination signal.
|
|
|
|
The Node Tuning Operator is part of a standard {product-title} installation in
|
|
version 4.1 and later.
