Constants ¶

const CSIName = names.NodeVolumeLimits

CSIName is the name of the plugin used in the plugin registry and configurations.

const (
	// ErrReasonMaxVolumeCountExceeded is used for MaxVolumeCount predicate error.
	ErrReasonMaxVolumeCountExceeded = "node(s) exceed max volume count"
)

Functions ¶

func NewCSI ¶

func NewCSI(_ context.Context, _ runtime.Object, handle fwk.Handle, fts feature.Features) (fwk.Plugin, error)

NewCSI initializes a new plugin and returns it.

func NewCSINodeLister ¶

func NewCSINodeLister(csiNodeLister storagelisters.CSINodeLister) *csiNodeListerWrapper

Types ¶

type CSILimits ¶

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

CSILimits is a plugin that checks node volume limits.

func (*CSILimits) EventsToRegister ¶

func (pl *CSILimits) EventsToRegister(_ context.Context) ([]fwk.ClusterEventWithHint, error)

EventsToRegister returns the possible events that may make a Pod. failed by this plugin schedulable.

func (*CSILimits) Filter ¶

func (pl *CSILimits) Filter(ctx context.Context, _ fwk.CycleState, pod *v1.Pod, nodeInfo fwk.NodeInfo) *fwk.Status

Filter invoked at the filter extension point.

func (*CSILimits) Name ¶

func (pl *CSILimits) Name() string

Name returns name of the plugin. It is used in logs, etc.

func (*CSILimits) PreFilter ¶

func (pl *CSILimits) PreFilter(ctx context.Context, _ fwk.CycleState, pod *v1.Pod, _ []fwk.NodeInfo) (*fwk.PreFilterResult, *fwk.Status)

PreFilter invoked at the prefilter extension point

If the pod haven't those types of volumes, we'll skip the Filter phase

func (*CSILimits) PreFilterExtensions ¶

func (pl *CSILimits) PreFilterExtensions() fwk.PreFilterExtensions

PreFilterExtensions returns prefilter extensions, pod add and remove.

func (*CSILimits) SignPod ¶

func (pl *CSILimits) SignPod(ctx context.Context, pod *v1.Pod) ([]fwk.SignFragment, *fwk.Status)

Feasibility and scoring based on the non-synthetic volume sources.

type DefaultCSIManager ¶

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

DefaultCSIManager is an implementation of the CSIManager interface.

func NewCSIManager ¶

func NewCSIManager(csiNodeLister storagelisters.CSINodeLister) *DefaultCSIManager

func (*DefaultCSIManager) CSINodes ¶

func (m *DefaultCSIManager) CSINodes() fwk.CSINodeLister

type InTreeToCSITranslator ¶

type InTreeToCSITranslator interface {
	IsPVMigratable(pv *v1.PersistentVolume) bool
	IsInlineMigratable(vol *v1.Volume) bool
	IsMigratableIntreePluginByName(inTreePluginName string) bool
	GetInTreePluginNameFromSpec(pv *v1.PersistentVolume, vol *v1.Volume) (string, error)
	GetCSINameFromInTreeName(pluginName string) (string, error)
	TranslateInTreePVToCSI(logger klog.Logger, pv *v1.PersistentVolume) (*v1.PersistentVolume, error)
	TranslateInTreeInlineVolumeToCSI(logger klog.Logger, volume *v1.Volume, podNamespace string) (*v1.PersistentVolume, error)
}

InTreeToCSITranslator contains methods required to check migratable status and perform translations from InTree PV's to CSI
