Chapter 6. Tuned [tuned.openshift.io/v1] Description Tuned is a collection of rules that allows cluster-wide deployment of node-level sysctls and more flexibility to add custom tuning specified by user needs. These rules are translated and passed to all containerized Tuned daemons running in the cluster in the format that the daemons understand. The responsibility for applying the node-level tuning then lies with the containerized Tuned daemons. More info: https://github.com/openshift/cluster-node-tuning-operator Type object 6.1. Specification Property Type Description apiVersion string APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources kind string Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase.

More info: https://git.k8s.io/community/contributors/devel/api-conventions.md#spec-and-status status object TunedStatus is the status for a Tuned resource. 6.1.1. .spec Description spec is the specification of the desired behavior of Tuned. More info: https://git.k8s.io/community/contributors/devel/api-conventions.md#spec-and-status Type object Property Type Description managementState string managementState indicates whether the registry instance represented by this config instance is under operator management or not. Valid values are Force, Managed, Unmanaged, and Removed. profile array Tuned profiles. profile[] object A Tuned profile. recommend array Selection logic for all Tuned profiles. recommend[] object Selection logic for a single Tuned profile. 6.1.2. .spec.profile Description Tuned profiles. Type array 6.1.3. .spec.profile[] Description A Tuned profile. Type object Required data name Property Type Description data string Specification of the Tuned profile to be consumed by the Tuned daemon. name string Name of the Tuned profile to be used in the recommend section. 6.1.4. .spec.recommend Description Selection logic for all Tuned profiles. Type array 6.1.5. .spec.recommend[] Description Selection logic for a single Tuned profile. Type object Required priority profile Property Type Description machineConfigLabels object (string) MachineConfigLabels specifies the labels for a MachineConfig. The MachineConfig is created automatically to apply additional host settings (e.g. kernel boot parameters) profile 'Profile' needs and can only be applied by creating a MachineConfig. This involves finding all MachineConfigPools with machineConfigSelector matching the MachineConfigLabels and setting the profile 'Profile' on all nodes that match the MachineConfigPools' nodeSelectors. match array Rules governing application of a Tuned profile connected by logical OR operator. match[] object Rules governing application of a Tuned profile. operand object Optional operand configuration. priority integer Tuned profile priority. Highest priority is 0. profile string Name of the Tuned profile to recommend. 6.1.6. .spec.recommend[].match Description Rules governing application of a Tuned profile connected by logical OR operator. Type array 6.1.7. .spec.recommend[].match[] Description Rules governing application of a Tuned profile. Type object Required label Property Type Description label string Node or Pod label name. match array (undefined) Additional rules governing application of the tuned profile connected by logical AND operator. type string Match type: [node/pod]. If omitted, "node" is assumed. value string Node or Pod label value. If omitted, the presence of label name is enough to match. 6.1.8. .spec.recommend[].operand Description Optional operand configuration.

API endpoints The following API endpoints are available: /apis/tuned.openshift.io/v1/tuneds GET : list objects of kind Tuned /apis/tuned.openshift.io/v1/namespaces/{namespace}/tuneds DELETE : delete collection of Tuned GET : list objects of kind Tuned POST : create a Tuned /apis/tuned.openshift.io/v1/namespaces/{namespace}/tuneds/{name} DELETE : delete a Tuned GET : read the specified Tuned PATCH : partially update the specified Tuned PUT : replace the specified Tuned 6.2.1. /apis/tuned.openshift.io/v1/tuneds HTTP method GET Description list objects of kind Tuned Table 6.1.

Query parameters Parameter Type Description dryRun string When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed fieldValidation string fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered. Table 6.5. Body parameters Parameter Type Description body Tuned schema Table 6.6.
