NewRestartConfig creates a restartDaemonConfig for the given node and daemon.

func Query

func Query(c clientset.Interface, query string) (*influxdb.Response, error)

Query sends a command to the server and returns the Response

func RemoveCleanupAction

func RemoveCleanupAction(p CleanupActionHandle)

RemoveCleanupAction removes a function that was installed by AddCleanupAction.

func ReplicaSetServeImageOrFail

func ReplicaSetServeImageOrFail(f *framework.Framework, test string, image string)

A basic test to check the deployment of an image using a ReplicaSet. The image serves its hostname which is checked for each replica.

func ReserveCpu

func ReserveCpu(f *framework.Framework, id string, replicas, millicores int)

func ReserveMemory

func ReserveMemory(f *framework.Framework, id string, replicas, megabytes int, expectRunning bool)

func ResizeGroup

func ResizeGroup(group string, size int32) error

func RunCleanupActions

func RunCleanupActions()

RunCleanupActions runs all functions installed by AddCleanupAction. It does not remove them (see RemoveCleanupAction) but it does run unlocked, so they may remove themselves.

func RunE2ETests

func RunE2ETests(t *testing.T)

TestE2E checks configuration parameters (specified through flags) and then runs E2E tests using the Ginkgo runner. If a "report directory" is specified, one or more JUnit test reports will be generated in this directory, and cluster logs will also be saved. This function is called on each Ginkgo node in parallel mode.

func RunLogPodsWithSleepOf

func RunLogPodsWithSleepOf(f *framework.Framework, sleep time.Duration, podname string, timeout time.Duration)

RunLogPodsWithSleepOf creates a pod on every node, logs continuously (with "sleep" pauses), and verifies that the log string was produced in each and every pod at least once. The final arg is the timeout for the test to verify all the pods got logs.

func ServeImageOrFail

func ServeImageOrFail(f *framework.Framework, test string, image string)

A basic test to check the deployment of an image using a replication controller. The image serves its hostname which is checked for each replica.

func SkipIfAppArmorNotSupported

func SkipIfAppArmorNotSupported()

func SpreadRCOrFail

func SpreadRCOrFail(f *framework.Framework, replicaCount int32, image string)

Check that the pods comprising a replication controller get spread evenly across available zones

func SpreadServiceOrFail

func SpreadServiceOrFail(f *framework.Framework, replicaCount int, image string)

Check that the pods comprising a service get spread evenly across available zones

func WaitForClusterSizeFunc

func WaitForClusterSizeFunc(c clientset.Interface, sizeFunc func(int) bool, timeout time.Duration) error

WaitForClusterSize waits until the cluster size matches the given function.

func WaitForGroupSize

func WaitForGroupSize(group string, size int32) error

func WaitForTerminatedContainer

func WaitForTerminatedContainer(f *framework.Framework, pod *v1.Pod, containerName string) error
