GetV1Client returns a client for the PodResourcesLister grpc service

func GetV1alpha1Client

func GetV1alpha1Client(socket string, connectionTimeout time.Duration, maxMsgSize int) (v1alpha1.PodResourcesListerClient, *grpc.ClientConn, error)

GetV1alpha1Client returns a client for the PodResourcesLister grpc service Note: This is deprecated

func NewV1PodResourcesServer

func NewV1PodResourcesServer(podsProvider PodsProvider, devicesProvider DevicesProvider, cpusProvider CPUsProvider, memoryProvider MemoryProvider) v1.PodResourcesListerServer

NewV1PodResourcesServer returns a PodResourcesListerServer which lists pods provided by the PodsProvider with device information provided by the DevicesProvider

func NewV1alpha1PodResourcesServer

NewV1alpha1PodResourcesServer returns a PodResourcesListerServer which lists pods provided by the PodsProvider with device information provided by the DevicesProvider

Types

type CPUsProvider

type CPUsProvider interface {
	// GetCPUs returns information about the cpus assigned to pods and containers
	GetCPUs(podUID, containerName string) []int64
	// GetAllocatableCPUs returns the allocatable (not allocated) CPUs
	GetAllocatableCPUs() []int64
}

CPUsProvider knows how to provide the cpus used by the given container

type DevicesProvider

type DevicesProvider interface {
	// UpdateAllocatedDevices frees any Devices that are bound to terminated pods.
	UpdateAllocatedDevices()
	// GetDevices returns information about the devices assigned to pods and containers
	GetDevices(podUID, containerName string) []*podresourcesapi.ContainerDevices
	// GetAllocatableDevices returns information about all the devices known to the manager
	GetAllocatableDevices() []*podresourcesapi.ContainerDevices
}

DevicesProvider knows how to provide the devices used by the given container

type MemoryProvider

type MemoryProvider interface {
	// GetMemory returns information about the memory assigned to containers
	GetMemory(podUID, containerName string) []*podresourcesapi.ContainerMemory
	// GetAllocatableMemory returns the allocatable memory from the node
	GetAllocatableMemory() []*podresourcesapi.ContainerMemory
}

type PodsProvider

type PodsProvider interface {
	GetPods() []*v1.Pod
}

PodsProvider knows how to provide the pods admitted by the node
