CleanupPods deletes the given pods and waits for them to be actually deleted.

func CleanupTest

func CleanupTest(t *testing.T, testCtx *TestContext)

CleanupTest cleans related resources which were created during integration test

func GetTolerationSeconds

func GetTolerationSeconds(tolerations []v1.Toleration) (int64, error)

func NewMockGCECloud

func NewMockGCECloud(cloud cloud.Cloud) (*gce.Cloud, error)

NewMockGCECloud returns a handle to a Cloud instance that is served by a mock http server

func NodeCopyWithConditions

func NodeCopyWithConditions(node *v1.Node, conditions []v1.NodeCondition) *v1.Node

NodeCopyWithConditions duplicates the ode object with conditions

func NodeReadyStatus

func NodeReadyStatus(conditions []v1.NodeCondition) (v1.ConditionStatus, error)

NodeReadyStatus returns the status of first condition with type NodeReady. If none of the condition is of type NodeReady, returns an error.

func NodeTainted

func NodeTainted(cs clientset.Interface, nodeName string, taints []v1.Taint) wait.ConditionFunc

NodeTainted return a condition function that returns true if the given node contains the taints.

func PodDeleted

func PodDeleted(c clientset.Interface, podNamespace, podName string) wait.ConditionFunc

PodDeleted returns true if a pod is not found in the given namespace.

func PodScheduled

func PodScheduled(c clientset.Interface, podNamespace, podName string) wait.ConditionFunc

PodScheduled checks if the pod has been scheduled

func RemoveTaintOffNode

func RemoveTaintOffNode(cs clientset.Interface, nodeName string, taint v1.Taint) error

RemoveTaintOffNode removes a specific taint from a node

func UpdateNodeStatus

func UpdateNodeStatus(cs clientset.Interface, node *v1.Node) error

UpdateNodeStatus updates the status of node.

func WaitForNodeTaints

func WaitForNodeTaints(cs clientset.Interface, node *v1.Node, taints []v1.Taint) error

WaitForNodeTaints waits for a node to have the target taints and returns an error if it does not have taints within the given timeout.

func WaitForPodToSchedule

func WaitForPodToSchedule(cs clientset.Interface, pod *v1.Pod) error

WaitForPodToSchedule waits for a pod to get scheduled and returns an error if it does not get scheduled within the timeout duration (30 seconds).

func WaitForPodToScheduleWithTimeout

func WaitForPodToScheduleWithTimeout(cs clientset.Interface, pod *v1.Pod, timeout time.Duration) error

WaitForPodToScheduleWithTimeout waits for a pod to get scheduled and returns an error if it does not scheduled within the given timeout.

func WaitForSchedulerCacheCleanup

func WaitForSchedulerCacheCleanup(sched *scheduler.Scheduler, t *testing.T)

WaitForSchedulerCacheCleanup waits for cleanup of scheduler's cache to complete

Types

type ShutdownFunc

type ShutdownFunc func()

ShutdownFunc represents the function handle to be called, typically in a defer handler, to shutdown a running module

func StartApiserver

func StartApiserver() (string, ShutdownFunc)

StartApiserver starts a local API server for testing and returns the handle to the URL and the shutdown function to stop it.

func StartFakePVController

func StartFakePVController(clientSet clientset.Interface) ShutdownFunc

StartFakePVController is a simplified pv controller logic that sets PVC VolumeName and annotation for each PV binding. TODO(mborsz): Use a real PV controller here.

func StartScheduler

func StartScheduler(clientSet clientset.Interface, kubeConfig *restclient.Config, cfg *kubeschedulerconfig.KubeSchedulerConfiguration) (*scheduler.Scheduler, coreinformers.PodInformer, ShutdownFunc)

StartScheduler configures and starts a scheduler given a handle to the clientSet interface and event broadcaster. It returns the running scheduler, podInformer and the shutdown function to stop it.
