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

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

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

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 PatchNodeCIDR

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

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

func PatchNodeCIDRs

func PatchNodeCIDRs(c clientset.Interface, node types.NodeName, cidrs []string) error

PatchNodeCIDRs patches the specified node.CIDR=cidrs[0] and node.CIDRs 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.

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.
