Functions

func GetHostname

func GetHostname(hostnameOverride string) (string, error)

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 GetNodeIP

func GetNodeIP(client clientset.Interface, hostname string) net.IP

GetNodeIP returns the ip of node with the provided hostname

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 PatchNodeCIDR

func PatchNodeCIDR(c clientset.Interface, node types.NodeName, cidr string) error

PatchNodeCIDR patches the specified node's CIDR to the given value.

func PatchNodeStatus

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