NewGenericConfiguration creates a new generic configuration.

type MetricsConfiguration

type PodSinglePortSDConf struct {
	PortName  string
	PodLister labels.Selector
}

func NewPodSingleSDConf added in v0.4.0 

func NewPodSingleSDConf() *PodSinglePortSDConf

type QoSConfiguration 

type QoSConfiguration struct {
	sync.RWMutex

	// QoSClassAnnotationSelector is used as an expanded way to match legacy specified
	// QoS annotations into standard katalyst QoS level
	// - if no expended selector is configured
	// --- only use the default key-value instead
	// - if multiple expended selectors are defined
	// --- returns true if anyone matches
	// - we should also do validation
	QoSClassAnnotationSelector map[string]map[string]string

	// QoSEnhancementAnnotationKey is used as an expanded way to match legacy specified
	// QoS annotations into standard katalyst QoS enhancement
	QoSEnhancementAnnotationKey map[string]string

	// for different situation, there may be different default values for enhancement keys
	// we use options to control those different values
	// the key here is specific enhancement key such as "numa_binding", "numa_exclusive"
	// the value is the default value of the key
	QoSEnhancementDefaultValues map[string]string
	// contains filtered or unexported fields
}

QoSConfiguration stores the qos configurations needed by core katalyst components. since we may have legacy QoS judgement ways, we should map those legacy configs into standard katalyst QoS Level.

func NewQoSConfiguration 

func NewQoSConfiguration() *QoSConfiguration

NewQoSConfiguration creates a new qos configuration.

func (*QoSConfiguration) CheckDedicatedQoS 

func (c *QoSConfiguration) CheckDedicatedQoS(pod *v1.Pod, expandedAnnotations map[string]string) (bool, error)

CheckDedicatedQoS returns true if the annotation indicates for DedicatedCores; - returns error if different QoS configurations conflict with each other.

func (c *QoSConfiguration) CheckDedicatedQoSForPod(pod *v1.Pod) (bool, error)

func (*QoSConfiguration) CheckReclaimedQoS 

func (c *QoSConfiguration) CheckReclaimedQoS(pod *v1.Pod, expandedAnnotations map[string]string) (bool, error)

CheckReclaimedQoS returns true if the annotation indicates for ReclaimedCores; - returns error if different QoS configurations conflict with each other.

func (*QoSConfiguration) CheckReclaimedQoSForPod 

func (c *QoSConfiguration) CheckReclaimedQoSForPod(pod *v1.Pod) (bool, error)

func (*QoSConfiguration) CheckSharedQoS 

func (c *QoSConfiguration) CheckSharedQoS(pod *v1.Pod, expandedAnnotations map[string]string) (bool, error)

CheckSharedQoS returns true if the annotation indicates for SharedCores; - returns error if different QoS configurations conflict with each other.

func (*QoSConfiguration) CheckSharedQoSForPod 

func (c *QoSConfiguration) CheckSharedQoSForPod(pod *v1.Pod) (bool, error)

func (*QoSConfiguration) CheckSystemQoS 

func (c *QoSConfiguration) CheckSystemQoS(pod *v1.Pod, expandedAnnotations map[string]string) (bool, error)

CheckSystemQoS returns true if the annotation indicates for SystemCores; - returns error if different QoS configurations conflict with each other.

func (*QoSConfiguration) FilterQoSEnhancementMap added in v0.4.1 

func (c *QoSConfiguration) FilterQoSEnhancementMap(annotations map[string]string) map[string]string

FilterQoSEnhancementMap filter map that are related to katalyst Enhancement. for enhancements,we should unmarshal and store the unmarshal key-value. it works both for default katalyst QoS keys and expanded QoS keys.

func (*QoSConfiguration) FilterQoSMap

GetQoSLevel returns the standard katalyst QoS Level for given annotations; - returns error if there is conflict in qos level annotations or can't get valid qos level. - returns defaultQoSLevel if nothing matches and isNotDefaultQoSLevel is false.

func (*QoSConfiguration) GetQoSLevelForPod

type QoSEnhancementExpander interface {
	Override(flattenedEnhancements map[string]string, pod *v1.Pod, expandedAnnotations map[string]string) (map[string]string, bool)
}

QoSEnhancementExpander provides a mechanism for user-specified qos-enhancement judgement since we may need to set qos-enhancement for some customized cases

type QoSLevelExpander interface {
	Override(qosLevel string, pod *v1.Pod, expandedAnnotations map[string]string) (string, bool)
}
