Functions

func KubeletCommand

func KubeletCommand(kOp KubeletOpt, c clientset.Interface, pod *v1.Pod)

KubeletCommand performs `start`, `restart`, or `stop` on the kubelet running on the node of the target pod and waits for the desired statues.. - First issues the command via `systemctl` - If `systemctl` returns stderr "command not found, issues the command via `service` - If `service` also returns stderr "command not found", the test is aborted. Allowed kubeletOps are `KStart`, `KStop`, and `KRestart`

func PodExec

func PodExec(pod *v1.Pod, bashExec string) (string, error)

PodExec wraps RunKubectl to execute a bash cmd in target pod

func RunInPodWithVolume

func RunInPodWithVolume(c clientset.Interface, ns, claimName, command string)

RunInPodWithVolume runs a command in a pod with given claim mounted to /mnt directory.

func SIGDescribe

func SIGDescribe(text string, body func()) bool

func TestKubeletRestartsAndRestoresMount

func TestKubeletRestartsAndRestoresMount(c clientset.Interface, f *framework.Framework, clientPod *v1.Pod, pvc *v1.PersistentVolumeClaim, pv *v1.PersistentVolume)

TestKubeletRestartsAndRestoresMount tests that a volume mounted to a pod remains mounted after a kubelet restarts

func TestVolumeUnmountsFromDeletedPod

func TestVolumeUnmountsFromDeletedPod(c clientset.Interface, f *framework.Framework, clientPod *v1.Pod, pvc *v1.PersistentVolumeClaim, pv *v1.PersistentVolume)

TestVolumeUnmountsFromDeletedPod tests that a volume unmounts if the client pod was deleted while the kubelet was down.
