Functions

func CheckHostname

func CheckHostname(c clientset.Interface, ss *appsv1.StatefulSet) error

    CheckHostname verifies that all Pods in ss have the correct Hostname. If the returned error is not nil than verification failed.

    func CheckMount

    func CheckMount(c clientset.Interface, ss *appsv1.StatefulSet, mountPath string) error

      CheckMount checks that the mount at mountPath is valid for all Pods in ss.

      func CheckServiceName

      func CheckServiceName(ss *appsv1.StatefulSet, expectedServiceName string) error

        CheckServiceName asserts that the ServiceName for ss is equivalent to expectedServiceName.

        func CreateStatefulSet

        func CreateStatefulSet(c clientset.Interface, manifestPath, ns string) *appsv1.StatefulSet

          CreateStatefulSet creates a StatefulSet from the manifest at manifestPath in the Namespace ns using kubectl create.

          func DeleteAllStatefulSets

          func DeleteAllStatefulSets(c clientset.Interface, ns string)

            DeleteAllStatefulSets deletes all StatefulSet API Objects in Namespace ns.

            func ExecInStatefulPods

            func ExecInStatefulPods(c clientset.Interface, ss *appsv1.StatefulSet, cmd string) error

              ExecInStatefulPods executes cmd in all Pods in ss. If a error occurs it is returned and cmd is not execute in any subsequent Pods.

              func GetPodList

              func GetPodList(c clientset.Interface, ss *appsv1.StatefulSet) *v1.PodList

                GetPodList gets the current Pods in ss.

                func NewStatefulSet

                func NewStatefulSet(name, ns, governingSvcName string, replicas int32, statefulPodMounts []v1.VolumeMount, podMounts []v1.VolumeMount, labels map[string]string) *appsv1.StatefulSet

                  NewStatefulSet creates a new Webserver StatefulSet for testing. The StatefulSet is named name, is in namespace ns, statefulPodsMounts are the mounts that will be backed by PVs. podsMounts are the mounts that are mounted directly to the Pod. labels are the labels that will be usd for the StatefulSet selector.

                  func NewStatefulSetPVC

                  func NewStatefulSetPVC(name string) v1.PersistentVolumeClaim

                    NewStatefulSetPVC returns a PersistentVolumeClaim named name, for testing StatefulSets.

                    func PauseNewPods

                    func PauseNewPods(ss *appsv1.StatefulSet)

                      PauseNewPods adds an always-failing ReadinessProbe to the StatefulSet PodTemplate. This causes all newly-created Pods to stay Unready until they are manually resumed with ResumeNextPod(). Note that this cannot be used together with SetHTTPProbe().

                      func Restart

                      func Restart(c clientset.Interface, ss *appsv1.StatefulSet)

                        Restart scales ss to 0 and then back to its previous number of replicas.

                        func ResumeNextPod

                        func ResumeNextPod(c clientset.Interface, ss *appsv1.StatefulSet)

                          ResumeNextPod allows the next Pod in the StatefulSet to continue by removing the ReadinessProbe added by PauseNewPods(), if it's still there. It fails the test if it finds any pods that are not in phase Running, or if it finds more than one paused Pod existing at the same time. This is a no-op if there are no paused pods.

                          func Saturate

                          func Saturate(c clientset.Interface, ss *appsv1.StatefulSet)

                            Saturate waits for all Pods in ss to become Running and Ready.

                            func Scale

                              Scale scales ss to count replicas.

                              func SortStatefulPods

                              func SortStatefulPods(pods *v1.PodList)

                                SortStatefulPods sorts pods by their ordinals

                                func UpdateReplicas

                                func UpdateReplicas(c clientset.Interface, ss *appsv1.StatefulSet, count int32)

                                  UpdateReplicas updates the replicas of ss to count.

                                  func WaitForPodReady

                                  func WaitForPodReady(c clientset.Interface, set *appsv1.StatefulSet, podName string) (*appsv1.StatefulSet, *v1.PodList)

                                    WaitForPodReady waits for the Pod named podName in set to exist and have a Ready condition.

                                    func WaitForRunning

                                    func WaitForRunning(c clientset.Interface, numPodsRunning, numPodsReady int32, ss *appsv1.StatefulSet)

                                      WaitForRunning waits for numPodsRunning in ss to be Running and for the first numPodsReady ordinals to be Ready.

                                      func WaitForRunningAndReady

                                      func WaitForRunningAndReady(c clientset.Interface, numStatefulPods int32, ss *appsv1.StatefulSet)

                                        WaitForRunningAndReady waits for numStatefulPods in ss to be Running and Ready.

                                        func WaitForState

                                        func WaitForState(c clientset.Interface, ss *appsv1.StatefulSet, until func(*appsv1.StatefulSet, *v1.PodList) (bool, error))

                                          WaitForState periodically polls for the ss and its pods until the until function returns either true or an error

                                          func WaitForStatusReadyReplicas(c clientset.Interface, ss *appsv1.StatefulSet, expectedReplicas int32)

                                            WaitForStatusReadyReplicas waits for the ss.Status.ReadyReplicas to be equal to expectedReplicas
