Types

type Adapter

type Adapter interface {
	// GetTopologyZones return newest topology zone status
	GetTopologyZones(ctx context.Context) ([]*nodev1alpha1.TopologyZone, error)

	// GetTopologyPolicy return newest topology policy status
	GetTopologyPolicy(ctx context.Context) (nodev1alpha1.TopologyPolicy, error)

	// Run is to start the topology adapter to watch the topology change
	Run(ctx context.Context, handler func()) error
}

Adapter is to get topology zone status, the src of that can be pod resource api or kubelet checkpoint.

func NewPodResourcesServerTopologyAdapter

func NewPodResourcesServerTopologyAdapter(metaServer *metaserver.MetaServer, qosConf *generic.QoSConfiguration,
	endpoints []string, kubeletResourcePluginPaths []string, resourceNameToZoneTypeMap map[string]string,
	skipDeviceNames sets.String, numaInfoGetter NumaInfoGetter, podResourcesFilter PodResourcesFilter,
	getClientFunc podresources.GetClientFunc, needValidationResources []string,
) (Adapter, error)

NewPodResourcesServerTopologyAdapter creates a topology adapter which uses pod resources server

type DummyAdapter

type DummyAdapter struct{}
