Functions

func AddFakeNodes

func AddFakeNodes(zoneGetter *ZoneGetter, newZone string, instances ...string) error

AddFakeNodes adds fake nodes to the ZoneGetter in the provided zone.

func DeleteFakeNodesInZone

func DeleteFakeNodesInZone(t *testing.T, zone string, zoneGetter *ZoneGetter)

DeleteFakeNodesInZone deletes all nodes in a zone.

func FakeNodeInformer

func PopulateFakeNodeInformer

func PopulateFakeNodeInformer(nodeInformer cache.SharedIndexInformer)

PopulateFakeNodeInformer populates a fake node informer with fake nodes.

Types

type Filter

type Filter string

type Mode

type Mode int

const (
	// In GCP mode, the ZoneGetter will fetch the zone information from
	// k8s Node objects.
	GCP Mode = iota
	// In NonGCP mode, the ZoneGetter will only return the zone specified
	// in gce.conf directly.
	NonGCP
)

type ZoneGetter

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

ZoneGetter manages lookups for GCE instances to zones.

func NewNonGCPZoneGetter

func NewNonGCPZoneGetter(zone string) *ZoneGetter

NewNonGCPZoneGetter initialize a ZoneGetter in Non-GCP mode.

func NewZoneGetter

func NewZoneGetter(nodeInformer cache.SharedIndexInformer) *ZoneGetter

NewZoneGetter initialize a ZoneGetter in GCP mode.

func (*ZoneGetter) List

func (z *ZoneGetter) List(filter Filter, logger klog.Logger) ([]string, error)

List returns a list of zones containing nodes that satisfy the given node filtering mode.

func (*ZoneGetter) ZoneForNode

func (z *ZoneGetter) ZoneForNode(name string, logger klog.Logger) (string, error)

ZoneForNode returns the zone for a given node by looking up providerID.
