Functions

func NewScheduler

func NewScheduler(
	driverName string,
	capacity Capacity,
	clientSet kubernetes.Interface,
	pvcLister corelisters.PersistentVolumeClaimLister,
	scLister storagelisters.StorageClassLister,
) (http.Handler, error)

Types

type Capacity

type Capacity interface {
	// NodeCapacity returns the available PMEM for the node.
	NodeCapacity(nodeName string) (int64, error)
}

Capacity provides information of remaining free PMEM per node.

func CapacityViaMetrics
