func GetBoundedReadySchedulableNodes Uses

❖
func GetBoundedReadySchedulableNodes(c clientset.Interface, maxNodes int) (nodes *v1.NodeList, err error)

GetBoundedReadySchedulableNodes is like GetReadySchedulableNodes except that it returns at most maxNodes nodes. Use this to keep your test case from blowing up when run on a large cluster.

func GetClusterZones Uses

❖
func GetClusterZones(c clientset.Interface) (sets.String, error)

GetClusterZones returns the values of zone label collected from all nodes.

func GetExternalIP Uses

❖
func GetExternalIP(node *v1.Node) (string, error)

GetExternalIP returns node external IP concatenated with port 22 for ssh e.g. 1.2.3.4:22

func GetInternalIP Uses

❖
func GetInternalIP(node *v1.Node) (string, error)

GetInternalIP returns node internal IP

func GetPublicIps Uses

❖
func GetPublicIps(c clientset.Interface) ([]string, error)

GetPublicIps returns a public IP list of nodes.

func GetRandomReadySchedulableNode Uses

❖
func GetRandomReadySchedulableNode(c clientset.Interface) (*v1.Node, error)

GetRandomReadySchedulableNode gets a single randomly-selected node which is available for running pods on. If there are no available nodes it will return an error.

func GetReadyNodesIncludingTainted Uses

❖
func GetReadyNodesIncludingTainted(c clientset.Interface) (nodes *v1.NodeList, err error)

GetReadyNodesIncludingTainted returns all ready nodes, even those which are tainted. There are cases when we care about tainted nodes E.g. in tests related to nodes with gpu we care about nodes despite presence of nvidia.com/gpu=present:NoSchedule taint

func GetReadySchedulableNodes Uses

❖
func GetReadySchedulableNodes(c clientset.Interface) (nodes *v1.NodeList, err error)

GetReadySchedulableNodes addresses the common use case of getting nodes you can do work on. 1) Needs to be schedulable. 2) Needs to be ready. If EITHER 1 or 2 is not true, most tests will want to ignore the node entirely. If there are no nodes that are both ready and schedulable, this will return an error.

func IsConditionSetAsExpected Uses

❖
func IsConditionSetAsExpected(node *v1.Node, conditionType v1.NodeConditionType, wantTrue bool) bool

IsConditionSetAsExpected returns a wantTrue value if the node has a match to the conditionType, otherwise returns an opposite value of the wantTrue with detailed logging.

func IsConditionSetAsExpectedSilent Uses

❖
func IsConditionSetAsExpectedSilent(node *v1.Node, conditionType v1.NodeConditionType, wantTrue bool) bool

IsConditionSetAsExpectedSilent returns a wantTrue value if the node has a match to the conditionType, otherwise returns an opposite value of the wantTrue.

func IsNodeReady Uses

❖
func IsNodeReady(node *v1.Node) bool

IsNodeReady returns true if: 1) it's Ready condition is set to true 2) doesn't have NetworkUnavailable condition set to true

func IsNodeSchedulable Uses

❖
func IsNodeSchedulable(node *v1.Node) bool

IsNodeSchedulable returns true if: 1) doesn't have "unschedulable" field set 2) it also returns true from IsNodeReady

func NewRuntimeClassPod Uses

❖
func NewRuntimeClassPod(runtimeClassName string) *v1.Pod

NewRuntimeClassPod returns a test pod with the given runtimeClassName

func PickIP Uses

❖
func PickIP(c clientset.Interface) (string, error)

PickIP picks one public node IP

func PreconfiguredRuntimeClassHandler Uses

❖
func PreconfiguredRuntimeClassHandler(handler string) string

PreconfiguredRuntimeClassHandler returns configured runtime handler.

func RemoveTaintOffNode Uses

❖
func RemoveTaintOffNode(c clientset.Interface, nodeName string, taint v1.Taint)

RemoveTaintOffNode removes the given taint from the given node.

❖
func TotalReady(c clientset.Interface) (int, error)

TotalReady returns number of ready schedulable Nodes.

func TotalRegistered Uses

❖
func TotalRegistered(c clientset.Interface) (int, error)

TotalRegistered returns number of schedulable Nodes.

func WaitConditionToBe Uses

❖
func WaitConditionToBe(c clientset.Interface, name string, conditionType v1.NodeConditionType, wantTrue bool, timeout time.Duration) bool

WaitConditionToBe returns whether node "name's" condition state matches wantTrue within timeout. If wantTrue is true, it will ensure the node condition status is ConditionTrue; if it's false, it ensures the node condition is in any state other than ConditionTrue (e.g. not true or unknown).

func WaitForNodeToBeNotReady Uses

❖
func WaitForNodeToBeNotReady(c clientset.Interface, name string, timeout time.Duration) bool

WaitForNodeToBeNotReady returns whether node name is not ready (i.e. the readiness condition is anything but ready, e.g false or unknown) within timeout.

func WaitForNodeToBeReady Uses

❖
func WaitForNodeToBeReady(c clientset.Interface, name string, timeout time.Duration) bool

WaitForNodeToBeReady returns whether node name is ready within timeout.

func WaitForReadyNodes Uses

❖
func WaitForReadyNodes(c clientset.Interface, size int, timeout time.Duration) error

WaitForReadyNodes waits up to timeout for cluster to has desired size and there is no not-ready nodes in it. By cluster size we mean number of schedulable Nodes.

func WaitForTotalHealthy Uses

❖
func WaitForTotalHealthy(c clientset.Interface, timeout time.Duration) error

WaitForTotalHealthy checks whether all registered nodes are ready and all required Pods are running on them.

type PodNode Uses

❖
type PodNode struct {
    // Pod represents pod name
    Pod string
    // Node represents node name
    Node string
}

PodNode is a pod-node pair indicating which node a given pod is running on

func PodNodePairs Uses
