Functions

func AddLabelsToNode

func AddLabelsToNode(c clientset.Interface, nodeName string, labels map[string]string) error

func DoCleanupNode

func DoCleanupNode(client clientset.Interface, nodeName string, strategy PrepareNodeStrategy) error

func DoPrepareNode

func DoPrepareNode(client clientset.Interface, node *api.Node, strategy PrepareNodeStrategy) error

func FailedContainers

func FailedContainers(pod *api.Pod) map[string]ContainerFailures

FailedContainers inspects all containers in a pod and returns failure information for containers that have failed or been restarted. A map is returned where the key is the containerID and the value is a struct containing the restart and failure information

func MakePodSpec

func MakePodSpec() api.PodSpec

func MakeTempDirOrDie

func MakeTempDirOrDie(prefix string, baseDir string) string

func PodNotReady

func PodNotReady(p *api.Pod) (bool, error)

PodNotReady checks whether pod p's has a ready condition of status false.

func PodReady

func PodReady(pod *api.Pod) bool

podReady returns whether pod has a condition of Ready with a status of true. TODO: should be replaced with api.IsPodReady

func PodRunningReady

func PodRunningReady(p *api.Pod) (bool, error)

PodRunningReady checks whether pod p's phase is running and it has a ready condition of status true.

func PodRunningReadyOrSucceeded

func PodRunningReadyOrSucceeded(p *api.Pod) (bool, error)

func RemoveLabelOffNode

func RemoveLabelOffNode(c clientset.Interface, nodeName string, labelKeys []string) error

RemoveLabelOffNode is for cleaning up labels temporarily added to node, won't fail if target label doesn't exist or has been removed.

func RunDeployment

func RunDeployment(config DeploymentConfig) error

RunDeployment Launches (and verifies correctness) of a Deployment and will wait for all pods it spawns to become "Running". It's the caller's responsibility to clean up externally (i.e. use the namespace lifecycle for handling Cleanup).

func RunRC

func RunRC(config RCConfig) error

RunRC Launches (and verifies correctness) of a Replication Controller and will wait for all pods it spawns to become "Running". It's the caller's responsibility to clean up externally (i.e. use the namespace lifecycle for handling Cleanup).

func RunReplicaSet

func RunReplicaSet(config ReplicaSetConfig) error

RunReplicaSet launches (and verifies correctness) of a ReplicaSet and waits until all the pods it launches to reach the "Running" state. It's the caller's responsibility to clean up externally (i.e. use the namespace lifecycle for handling Cleanup).

func StartPods

func StartPods(c clientset.Interface, replicas int, namespace string, podNamePrefix string,
	pod api.Pod, waitForRunning bool, logFunc func(fmt string, args ...interface{})) error

Simplified version of RunRC, that does not create RC, but creates plain Pods. Optionally waits for pods to start running (if waitForRunning == true). The number of replicas must be non-zero.

func TerminatedContainers

func TerminatedContainers(pod *api.Pod) map[string]string

TerminatedContainers inspects all containers in a pod and returns a map of "container name: termination reason", for all currently terminated containers.

func VerifyLabelsRemoved

func VerifyLabelsRemoved(c clientset.Interface, nodeName string, labelKeys []string) error

VerifyLabelsRemoved checks if Node for given nodeName does not have any of labels from labelKeys. Return non-nil error if it does.

func WaitForPodsWithLabelRunning

func WaitForPodsWithLabelRunning(c clientset.Interface, ns string, label labels.Selector) error

Wait up to 10 minutes for all matching pods to become Running and at least one matching pod exists.
