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 "primary" IP; see GetNodeHostIPs for more details

func GetNodeHostIPs added in v1.20.0

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 GetNodeIP added in v1.13.0

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

GetNodeIP returns an IP (as with GetNodeHostIP) for the node with the provided name. If required, it will wait for the node to be created.

func GetPreferredNodeAddress added in v1.5.0

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 added in v1.24.0

func IsNodeReady(node *v1.Node) bool

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

Types

type NoMatchError added in v1.14.0

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 added in v1.14.0

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.
