Variables

var ErrNoMachineIPAddr = errors.New("no IP addresses found for machine")

ErrNoMachineIPAddr indicates that no valid IP addresses were found in a machine context

Functions

func ConvertProviderIDToUUID

func ConvertProviderIDToUUID(providerID *string) string

ConvertProviderIDToUUID transforms a provider ID into a UUID string. If providerID is nil, empty, or invalid, then an empty string is returned. A valid providerID should adhere to the format specified by ProviderIDPattern.

func ConvertUUIDToProviderID

func ConvertUUIDToProviderID(uuid string) string

ConvertUUIDToProviderID transforms a UUID string into a provider ID. If the supplied UUID is empty or invalid then an empty string is returned. A valid UUID should adhere to the format specified by UUIDPattern.

func GetMachineMetadata

func GetMachineMetadata(hostname string, vsphereVM infrav1.VSphereVM, networkStatuses ...infrav1.NetworkStatus) ([]byte, error)

GetMachineMetadata returns the cloud-init metadata as a base-64 encoded string for a given VSphereMachine.

func GetMachinePreferredIPAddress

func GetMachinePreferredIPAddress(machine *infrav1.VSphereMachine) (string, error)

GetMachinePreferredIPAddress returns the preferred IP address for a VSphereMachine resource.

func GetMachinesInCluster

func GetMachinesInCluster(
	ctx context.Context,
	controllerClient client.Client,
	namespace, clusterName string) ([]*clusterv1.Machine, error)

GetMachinesInCluster gets a cluster's Machine resources.

func GetOwnerVSphereMachine

func GetOwnerVSphereMachine(ctx context.Context, c client.Client, obj metav1.ObjectMeta) (*infrav1.VSphereMachine, error)

func GetVSphereMachine

func GetVSphereMachine(
	ctx context.Context,
	controllerClient client.Client,
	namespace, machineName string) (*infrav1.VSphereMachine, error)

GetVSphereMachine gets a VSphereMachine resource for the given CAPI Machine.

func GetVSphereMachinesInCluster

func GetVSphereMachinesInCluster(
	ctx context.Context,
	controllerClient client.Client,
	namespace, clusterName string) ([]*infrav1.VSphereMachine, error)

GetVSphereMachinesInCluster gets a cluster's VSphereMachine resources.

func IsControlPlaneMachine

func IsControlPlaneMachine(machine metav1.Object) bool

IsControlPlaneMachine returns true if the provided resource is a member of the control plane.

func NewKubeClient

func NewKubeClient(
	ctx context.Context,
	controllerClient client.Client,
	cluster *clusterv1.Cluster) (kubernetes.Interface, error)

NewKubeClient returns a new client for the target cluster using the KubeConfig secret stored in the management cluster.
