The following CR applies custom node-level tuning for
|
|
{product-title} nodes with label
|
|
`tuned.openshift.io/ingress-node-label` set to any value.

|
====
|
|
Custom profile writers are strongly encouraged to include the default Tuned
|
|
daemon profiles shipped within the default Tuned CR. The example above uses the
|
|
default `openshift-control-plane` profile to accomplish this.
