Constants

❖
const (
    // NodeUnreachablePodReason is the reason on a pod when its state cannot be confirmed as kubelet is unresponsive
    // on the node it is (was) running.
    NodeUnreachablePodReason = "NodeLost"
    // NodeUnreachablePodMessage is the message on a pod when its state cannot be confirmed as kubelet is unresponsive

    NodeUnreachablePodMessage = "Node %v which was running pod %v is unresponsive"

func GetHostname Uses

❖
func GetHostname(hostnameOverride string) (string, error)

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

func GetNodeHostIP Uses

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

GetNodeHostIP returns the provided node's "primary" IP; see GetNodeHostIPs for more details

func GetNodeHostIPs Uses

❖
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 Uses

❖
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 Uses

❖
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 Uses

❖
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. Since there are currently two separate zone keys: 

* "failure-domain.beta.kubernetes.io/zone"
* "topology.kubernetes.io/zone"

GetZoneKey will first check failure-domain.beta.kubernetes.io/zone and if not exists, will then check topology.kubernetes.io/zone

func PatchNodeCIDR Uses

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

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

func PatchNodeCIDRs Uses

❖
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 Uses

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

PatchNodeStatus patches node status.

func SetNodeCondition Uses

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

SetNodeCondition updates specific node condition with patch operation.

type NoMatchError Uses

❖
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 Uses

❖
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.
