CommonImageWhiteList is the list of images used in common test. These images should be prepulled before a tests starts, so that the tests won't fail due image pulling flakes. Currently, this is only used by node e2e test. TODO(random-liu): Change the image puller pod to use similar mechanism.

Functions

func CreateAppArmorTestPod

func CreateAppArmorTestPod(f *framework.Framework, unconfined bool, runOnce bool) *api.Pod

CreateAppArmorTestPod creates a pod that tests apparmor profile enforcement. The pod exits with an error code if the profile is incorrectly enforced. If runOnce is true the pod will exit after a single test, otherwise it will repeat the test every 1 second until failure.

func CreateCPUHorizontalPodAutoscaler

func CreateCPUHorizontalPodAutoscaler(rc *ResourceConsumer, cpu, minReplicas, maxRepl int32) *autoscalingv1.HorizontalPodAutoscaler

func DeleteHorizontalPodAutoscaler

func DeleteHorizontalPodAutoscaler(rc *ResourceConsumer, autoscalerName string)

func GetResourceConsumerImage

func GetResourceConsumerImage() string

func IsAppArmorSupported

func IsAppArmorSupported() bool

func LoadAppArmorProfiles

func LoadAppArmorProfiles(f *framework.Framework)

func NewRCByName

func NewRCByName(c clientset.Interface, ns, name string, replicas int32, gracePeriod *int64) (*v1.ReplicationController, error)

NewRCByName creates a replication controller with a selector by name of name.

func NewSVCByName

func NewSVCByName(c clientset.Interface, ns, name string) error

func ObserveEventAfterAction

func ObserveEventAfterAction(f *framework.Framework, eventPredicate func(*v1.Event) bool, action Action) (bool, error)

Returns true if an event matching the predicate was emitted from the system after performing the supplied action.

func ObserveNodeUpdateAfterAction

func ObserveNodeUpdateAfterAction(f *framework.Framework, nodeName string, nodePredicate func(*v1.Node) bool, action Action) (bool, error)

Returns true if a node update matching the predicate was emitted from the system after performing the supplied action.

func RestartNodes

func RestartNodes(c clientset.Interface, nodes []v1.Node) error

func SkipIfAppArmorNotSupported

func SkipIfAppArmorNotSupported()

Types

type Action
