Functions

func GetReservationKey 

func GetReservationKey(r *schedulingv1alpha1.Reservation) string

func GetReservationNameFromReservePod 

func GetReservationNameFromReservePod(pod *corev1.Pod) string

func GetReservationNodeName 

func GetReservationNodeName(r *schedulingv1alpha1.Reservation) string

func GetReservationSchedulerName 

func GetReservationSchedulerName(r *schedulingv1alpha1.Reservation) string

func GetReservePodKey 

func GetReservePodKey(pod *corev1.Pod) string

func GetReservePodNodeName 

func GetReservePodNodeName(pod *corev1.Pod) string

func IsReservationActive 

func IsReservationActive(r *schedulingv1alpha1.Reservation) bool

IsReservationActive checks if the reservation is scheduled and its status is Available/Waiting.

func IsReservationExpired 

func IsReservationExpired(r *schedulingv1alpha1.Reservation) bool

func IsReservationFailed 

func IsReservationFailed(r *schedulingv1alpha1.Reservation) bool

func IsReservationScheduled 

func IsReservationScheduled(r *schedulingv1alpha1.Reservation) bool

IsReservationScheduled checks if the reservation is scheduled on a node and its status is Available.

func IsReservePod 

func IsReservePod(pod *corev1.Pod) bool

func New 

func New(args runtime.Object, handle framework.Handle) (framework.Plugin, error)

func NewReservePod 

func NewReservePod(r *schedulingv1alpha1.Reservation) *corev1.Pod

NewReservePod returns a fake pod set as the reservation's specifications. The reserve pod is only visible for the scheduler and does not make actual creation on nodes.

func SetReservationNodeName 

func SetReservationNodeName(r *schedulingv1alpha1.Reservation, nodeName string)

func StatusNodeNameIndexFunc 

func StatusNodeNameIndexFunc(obj interface{}) ([]string, error)

StatusNodeNameIndexFunc is an index function that indexes based on a reservation's status.nodeName

func ValidateReservation 

func ValidateReservation(r *schedulingv1alpha1.Reservation) error

Types

type AvailableCache 

type AvailableCache struct {
	// contains filtered or unexported fields
}

AvailableCache is for efficiently querying the reservation allocation results. Typical usages are as below: 1. check if a pod match any of available reservations (ownership and resource requirements). 2. check which nodes a pod match available reservation are at. 3. check which reservations are on a node.

func (*AvailableCache) Add 

func (a *AvailableCache) Add(r *schedulingv1alpha1.Reservation)

func (*AvailableCache) Delete 

func (a *AvailableCache) Delete(r *schedulingv1alpha1.Reservation)

func (*AvailableCache) Get 

func (a *AvailableCache) Get(key string) *reservationInfo

func (*AvailableCache) GetOnNode 

func (a *AvailableCache) GetOnNode(nodeName string) []*reservationInfo

func (*AvailableCache) Len 

func (a *AvailableCache) Len() int

type Hook 

type Hook struct {
	// contains filtered or unexported fields
}

func NewHook 

func NewHook() *Hook

func (*Hook) FilterHook 

func (h *Hook) FilterHook(handle frameworkext.ExtendedHandle, cycleState *framework.CycleState, pod *corev1.Pod, nodeInfo *framework.NodeInfo) (*corev1.Pod, *framework.NodeInfo, bool)

func (*Hook) Name 

func (h *Hook) Name() string

func (*Hook) PreFilterHook 

func (h *Hook) PreFilterHook(handle frameworkext.ExtendedHandle, cycleState *framework.CycleState, pod *corev1.Pod) (*corev1.Pod, bool)

type Plugin 

type Plugin struct {
	// contains filtered or unexported fields
}

func (*Plugin) Bind 

func (p *Plugin) Bind(ctx context.Context, cycleState *framework.CycleState, pod *corev1.Pod, nodeName string) *framework.Status

Bind fake binds reserve pod and mark corresponding reservation as Available. NOTE: This Bind plugin should get called before DefaultBinder; plugin order should be configured.

func (*Plugin) Filter 

func (p *Plugin) Filter(ctx context.Context, cycleState *framework.CycleState, pod *corev1.Pod, nodeInfo *framework.NodeInfo) *framework.Status

Filter only processes pods either the pod is a reserve pod or a pod can allocate reserved resources on the node.

func (*Plugin) Name 

func (p *Plugin) Name() string

func (*Plugin) PostFilter 

func (p *Plugin) PostFilter(ctx context.Context, state *framework.CycleState, pod *corev1.Pod, filteredNodeStatusMap framework.NodeToStatusMap) (*framework.PostFilterResult, *framework.Status)

func (*Plugin) PreBind 

func (p *Plugin) PreBind(ctx context.Context, cycleState *framework.CycleState, pod *corev1.Pod, nodeName string) *framework.Status

func (*Plugin) PreFilter 

func (p *Plugin) PreFilter(ctx context.Context, cycleState *framework.CycleState, pod *corev1.Pod) *framework.Status

PreFilter checks if the pod is a reserve pod. If it is, update cycle state to annotate reservation scheduling. Also do validations in this phase.

func (*Plugin) PreFilterExtensions 

func (p *Plugin) PreFilterExtensions() framework.PreFilterExtensions

func (*Plugin) Reserve 

func (p *Plugin) Reserve(ctx context.Context, cycleState *framework.CycleState, pod *corev1.Pod, nodeName string) *framework.Status

func (*Plugin) Score 

func (p *Plugin) Score(ctx context.Context, cycleState *framework.CycleState, pod *corev1.Pod, nodeName string) (int64, *framework.Status)

func (*Plugin) ScoreExtensions 

func (p *Plugin) ScoreExtensions() framework.ScoreExtensions

func (*Plugin) Unreserve 

func (p *Plugin) Unreserve(ctx context.Context, cycleState *framework.CycleState, pod *corev1.Pod, nodeName string)
