func (*VSphere) InstanceTypeByProviderID

func (vs *VSphere) InstanceTypeByProviderID(providerID string) (string, error)

InstanceTypeByProviderID returns the cloudprovider instance type of the node with the specified unique providerID This method will not be called from the node that is requesting this ID. i.e. metadata service and other local methods cannot be used here

func (*VSphere) Instances

func (vs *VSphere) Instances() (cloudprovider.Instances, bool)

Instances returns an implementation of Instances for vSphere.

func (*VSphere) LoadBalancer

func (vs *VSphere) LoadBalancer() (cloudprovider.LoadBalancer, bool)

NodeAddresses is an implementation of Instances.NodeAddresses.

func (*VSphere) NodeAddressesByProviderID

func (vs *VSphere) NodeAddressesByProviderID(providerID string) ([]v1.NodeAddress, error)

NodeAddressesByProviderID returns the node addresses of an instances with the specified unique providerID This method will not be called from the node that is requesting this ID. i.e. metadata service and other local methods cannot be used here

func (*VSphere) ProviderName

func (vs *VSphere) ProviderName() string

ProviderName returns the cloud provider ID.

func (*VSphere) Routes

func (vs *VSphere) Routes() (cloudprovider.Routes, bool)
