func PVMultiNodeCheck added in v1.14.0

func PVMultiNodeCheck(client clientset.Interface, timeouts *framework.TimeoutContext, claim *v1.PersistentVolumeClaim, node e2epod.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, timeouts *framework.TimeoutContext, claim *v1.PersistentVolumeClaim, node e2epod.NodeSelection) *v1.PersistentVolume

PVWriteReadSingleNodeCheck checks that a PV retains data on a single node and returns the PV.

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 RunInPodWithVolume added in v1.14.0

func RunInPodWithVolume(c clientset.Interface, t *framework.TimeoutContext, ns, claimName, podName, command string, node e2epod.NodeSelection) *v1.Pod

	client clientset.Interface,
	class *storagev1.StorageClass,
) (*storagev1.StorageClass, func())

	Timeouts   *framework.TimeoutContext
	Namespace  string
	DriverName string
	VolSource  *v1.VolumeSource
	Node       e2epod.NodeSelection

	// GetVolume returns the volume attributes for a
	// certain inline ephemeral volume, enumerated starting with
	// #0. Some tests might require more than one volume. They can
	// all be the same or different, depending what the driver supports
	// and/or wants to test.
	//
	// For each volume, the test driver can specify the
	// attributes, whether two pods using those attributes will
	// end up sharing the same backend storage (i.e. changes made
	// in one pod will be visible in the other), and whether
	// the volume can be mounted read/write or only read-only.
	GetVolume func(volumeNumber int) (attributes map[string]string, shared bool, readOnly bool)

	// RunningPodCheck is invoked while a pod using an inline volume is running.
	// It can execute additional checks on the pod and its volume(s). Any data
	// returned by it is passed to StoppedPodCheck.
	RunningPodCheck func(pod *v1.Pod) interface{}

	// StoppedPodCheck is invoked after ensuring that the pod is gone.
	// It is passed the data gather by RunningPodCheck or nil if that
	// isn't defined and then can do additional checks on the node,
	// like for example verifying that the ephemeral volume was really
	// removed. How to do such a check is driver-specific and not
	// covered by the generic storage test suite.
	StoppedPodCheck func(nodeName string, runningPodData interface{})

	// NumInlineVolumes sets the number of ephemeral inline volumes per pod.
	// Unset (= zero) is the same as one.
	NumInlineVolumes int

	// ReadOnly limits mounting to read-only.
