Functions

func GetNodeHostIPs

func GetNodeHostIPs(node *v1.Node) ([]net.IP, error)

GetNodeHostIPs returns the provided node's IP(s); either a single "primary IP" for the node in a single-stack cluster, or a dual-stack pair of IPs in a dual-stack cluster (for nodes that actually have dual-stack IPs). Among other things, the IPs returned from this function are used as the `.status.PodIPs` values for host-network pods on the node, and the first IP is used as the `.status.HostIP` for all pods on the node.

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 IsNodeReady

func IsNodeReady(node *v1.Node) bool

IsNodeReady returns true if a node is ready; false otherwise.

Types

type NoMatchError

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

NoMatchError is a typed implementation of the error interface. It indicates a failure to get a matching Node.

func (*NoMatchError) Error

func (e *NoMatchError) Error() string

Error is the implementation of the conventional interface for representing an error condition, with the nil value representing no error.
