Types

type IMDSNodeProvider

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

IMDSNodeProvider implements nodemanager.NodeProvider.

func NewIMDSNodeProvider

func NewIMDSNodeProvider() *IMDSNodeProvider

NewIMDSNodeProvider creates a new IMDSNodeProvider.

func (*IMDSNodeProvider) GetZone

func (np *IMDSNodeProvider) GetZone(ctx 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. If the node is not running with availability zones, then it will fall back to fault domain.

func (*IMDSNodeProvider) InstanceID

func (np *IMDSNodeProvider) InstanceID(ctx context.Context, name types.NodeName) (string, error)

InstanceID returns the cloud provider ID of the specified instance. Note that if the instance does not exist or is no longer running, we must return ("", cloudprovider.InstanceNotFound)

func (*IMDSNodeProvider) InstanceType

func (np *IMDSNodeProvider) InstanceType(ctx context.Context, name types.NodeName) (string, error)

InstanceType returns the type of the specified instance. Note that if the instance does not exist or is no longer running, we must return ("", cloudprovider.InstanceNotFound) (Implementer Note): This is used by kubelet. Kubelet will label the node. Real log from kubelet:

Adding node label from cloud provider: beta.kubernetes.io/instance-type=[value]

func (*IMDSNodeProvider) NodeAddresses

func (np *IMDSNodeProvider) NodeAddresses(ctx context.Context, name types.NodeName) ([]v1.NodeAddress, error)

NodeAddresses returns the addresses of the specified instance.
