func NewCSI ¶
func NewCSI(_ context.Context, _ runtime.Object, handle framework.Handle, fts feature.Features) (framework.Plugin, error)
NewCSI initializes a new plugin and returns it.

NewCinder returns function that initializes a new plugin and returns it.
Types ¶
type CSILimits ¶
type CSILimits struct {
// contains filtered or unexported fields
}
CSILimits is a plugin that checks node volume limits.
func (*CSILimits) EventsToRegister ¶ added in v1.22.0
func (pl *CSILimits) EventsToRegister() []framework.ClusterEventWithHint
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, _ *framework.CycleState, pod *v1.Pod, nodeInfo *framework.NodeInfo) *framework.Status
Filter invoked at the filter extension point.
func (*CSILimits) PreFilter ¶ added in v1.28.0
func (pl *CSILimits) PreFilter(ctx context.Context, _ *framework.CycleState, pod *v1.Pod) (*framework.PreFilterResult, *framework.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 ¶ added in v1.28.0
func (pl *CSILimits) PreFilterExtensions() framework.PreFilterExtensions
PreFilterExtensions returns prefilter extensions, pod add and remove.
type InTreeToCSITranslator ¶ added in v1.18.0
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(pv *v1.PersistentVolume) (*v1.PersistentVolume, error)
TranslateInTreeInlineVolumeToCSI(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
type VolumeFilter ¶ added in v1.18.0
type VolumeFilter struct {
// Filter normal volumes
FilterVolume func(vol *v1.Volume) (id string, relevant bool)
FilterPersistentVolume func(pv *v1.PersistentVolume) (id string, relevant bool)
// MatchProvisioner evaluates if the StorageClass provisioner matches the running predicate
MatchProvisioner func(sc *storage.StorageClass) (relevant bool)
// IsMigrated returns a boolean specifying whether the plugin is migrated to a CSI driver
IsMigrated func(csiNode *storage.CSINode) bool
}
VolumeFilter contains information on how to filter PD Volumes when checking PD Volume caps.
