Functions

func GetHostname

func GetHostname(hostnameOverride string) string

GetHostname returns OS's hostname if 'hostnameOverride' is empty; otherwise, return 'hostnameOverride'.

func GetNodeHostIP

func GetNodeHostIP(node *v1.Node) (net.IP, error)

GetNodeHostIP returns the provided node's IP, based on the priority: 1. NodeInternalIP 2. NodeExternalIP

func GetPreferredNodeAddress

func GetPreferredNodeAddress(node *v1.Node, preferredAddressTypes []v1.NodeAddressType) (string, error)

GetPreferredNodeAddress returns the address of the provided node, using the provided preference order. If none of the preferred address types are found, an error is returned.

func GetZoneKey

func GetZoneKey(node *v1.Node) string

GetZoneKey is a helper function that builds a string identifier that is unique per failure-zone; it returns empty-string for no zone.

func InternalGetNodeHostIP

func InternalGetNodeHostIP(node *api.Node) (net.IP, error)

InternalGetNodeHostIP returns the provided node's IP, based on the priority: 1. NodeInternalIP 2. NodeExternalIP

func PatchNodeStatus

func PatchNodeStatus(c v1core.CoreV1Interface, nodeName types.NodeName, oldNode *v1.Node, newNode *v1.Node) (*v1.Node, error)

PatchNodeStatus patches node status.

func SetNodeCondition

func SetNodeCondition(c clientset.Interface, node types.NodeName, condition v1.NodeCondition) error

SetNodeCondition updates specific node condition with patch operation.
