Functions

func AddFakeNode

func AddFakeNode(zoneGetter *ZoneGetter, node *apiv1.Node) error

AddFakeNode adds fake node to the ZoneGetter.

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 FakeNodeInformer() cache.SharedIndexInformer

func PopulateFakeNodeInformer

func PopulateFakeNodeInformer(nodeInformer cache.SharedIndexInformer, addMSCNodes bool)

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 NewFakeZoneGetter

func NewFakeZoneGetter(nodeInformer cache.SharedIndexInformer, defaultSubnetURL string, onlyIncludeDefaultSubnetNodes bool) *ZoneGetter

NewFakeZoneGetter initialize a fake ZoneGetter in GCP mode to use in test.

func NewNonGCPZoneGetter

func NewNonGCPZoneGetter(zone string) *ZoneGetter

NewNonGCPZoneGetter initialize a ZoneGetter in Non-GCP mode.

func NewZoneGetter

func NewZoneGetter(nodeInformer cache.SharedIndexInformer, defaultSubnetURL string) *ZoneGetter

NewZoneGetter initialize a ZoneGetter in GCP mode.

func (*ZoneGetter) IsDefaultSubnetNode

func (z *ZoneGetter) IsDefaultSubnetNode(nodeName string, logger klog.Logger) (bool, error)

ZoneForNode returns if the given node is in default subnet.

func (*ZoneGetter) IsNodeSelectedByFilter

func (z *ZoneGetter) IsNodeSelectedByFilter(node *api_v1.Node, filter Filter, filterLogger klog.Logger) bool

IsNodeSelectedByFilter checks if the node matches the node filter mode.

func (*ZoneGetter) ListNodes

func (z *ZoneGetter) ListNodes(filter Filter, logger klog.Logger) ([]*api_v1.Node, error)

ListNodes returns a list of nodes that satisfy the given node filtering mode.

func (*ZoneGetter) ListZones

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

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

func (*ZoneGetter) ZoneAndSubnetForNode

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

ZoneAndSubnetForNode returns the zone and subnet for a given node by looking up providerID.
