Functions

func CheckForLeftoverVolumes

func CheckForLeftoverVolumes(volBefore map[string][]string)

CheckForLeftovers lists volumes again after test, diff means leftovers.

func GetHostVolumes

func GetHostVolumes() map[string][]string

Register list of volumes before test, using out-of-band host commands (i.e. not CSI API).

func PVWriteReadSingleNodeCheck

func PVWriteReadSingleNodeCheck(client clientset.Interface, claim *v1.PersistentVolumeClaim, id string)

PVWriteReadSingleNodeCheck checks that a PV retains data on a single node.

It starts two pods: - The first pod writes 'hello word' to the /mnt/test (= the volume) on one node. - The second pod runs grep 'hello world' on /mnt/test on the same node.

The node is selected by Kubernetes when scheduling the first pod. It's then selected via its name for the second pod.

If both succeed, Kubernetes actually allocated something that is persistent across pods.

This is a common test that can be called from a StorageClassTest.PvCheck.

func TestDynamicLateBindingProvisioning

func TestDynamicLateBindingProvisioning(client clientset.Interface, claim *v1.PersistentVolumeClaim, id string)

TestDynamicLateBindingProvisioning is a variant of k8s.io/kubernetes/test/e2e/storage/testsuites/provisioning.go which works with late binding.

func WaitForPodsWithLabelRunningReady

func WaitForPodsWithLabelRunningReady(c clientset.Interface, ns string, label labels.Selector, num int, timeout time.Duration) (pods *v1.PodList, err error)

This is a copy from framework/utils.go with the fix from https://github.com/kubernetes/kubernetes/pull/78687 TODO: update to Kubernetes 1.15 (assuming that PR gets merged in time for that) and remove this function.
