Types

type ZonesController

type ZonesController struct {
	K8sClient clientset.Interface
	// contains filtered or unexported fields
}

func New

func New(client *metalgo.Driver) *ZonesController

New returns a new zones controller that satisfies the kubernetes cloud provider zones interface

func (ZonesController) GetZone

func (z ZonesController) GetZone(_ context.Context) (cloudprovider.Zone, error)

GetZone returns the Zone containing the current failure zone and locality region that the program is running in. In most cases, this method is called from the kubelet querying a local metadata service to acquire its zone. For the case of external cloud providers, use GetZoneByProviderID or GetZoneByNodeName since GetZone can no longer be called from the kubelets.

func (ZonesController) GetZoneByNodeName

func (z ZonesController) GetZoneByNodeName(_ context.Context, nodeName types.NodeName) (cloudprovider.Zone, error)

GetZoneByNodeName returns the Zone containing the current zone and locality region of the node specified by node name. This method is particularly used in the context of external cloud providers where node initialization must be done outside the kubelets.

func (ZonesController) GetZoneByProviderID

func (z ZonesController) GetZoneByProviderID(_ context.Context, providerID string) (cloudprovider.Zone, error)

GetZoneByProviderID returns the Zone containing the current zone and locality region of the node specified by providerID. This method is particularly used in the context of external cloud providers where node initialization must be done outside the kubelets.
