func GetDriverNameWithFeatureTags added in v1.14.0 

func GetDriverNameWithFeatureTags(driver TestDriver) string

GetDriverNameWithFeatureTags returns driver name with feature tags For example)

  • [Driver: nfs]
  • [Driver: rbd][Feature:Volumes]

func GetSnapshotClass added in v1.14.0 

func GetSnapshotClass(
	snapshotter string,
	parameters map[string]string,
	ns string,
	suffix string,
) *unstructured.Unstructured

GetSnapshotClass constructs a new SnapshotClass instance with a unique name that is based on namespace + suffix.

func GetStorageClass added in v1.14.0

	provisioner string,
	parameters map[string]string,
	bindingMode *storagev1.VolumeBindingMode,
	ns string,

func GetUniqueDriverName 

func GetUniqueDriverName(driver TestDriver) string

func PVMultiNodeCheck added in v1.14.0 

func PVMultiNodeCheck(client clientset.Interface, claim *v1.PersistentVolumeClaim, volume *v1.PersistentVolume, node NodeSelection)

PVMultiNodeCheck checks that a PV retains data when moved between nodes.

It starts these 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 another node.

The first node is selected by Kubernetes when scheduling the first pod. The second pod uses the same criteria, except that a special anti-affinity for the first node gets added. This test can only pass if the cluster has more than one suitable node. The caller has to ensure that.

If all succeeds, Kubernetes actually allocated something that is persistent across pods and across nodes.

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

func PVWriteReadSingleNodeCheck added in v1.14.0 

func PVWriteReadSingleNodeCheck(client clientset.Interface, claim *v1.PersistentVolumeClaim, volume *v1.PersistentVolume, node NodeSelection)

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.
