func CheckHostname(ctx context.Context, 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(ctx context.Context, 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(ss *appsv1.StatefulSet, expectedServiceName string) error
CheckServiceName asserts that the ServiceName for ss is equivalent to expectedServiceName.
func CreateStatefulSet(ctx context.Context, 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(ctx context.Context, c clientset.Interface, ns string)
DeleteAllStatefulSets deletes all StatefulSet API Objects in Namespace ns.
func ExecInStatefulPods(ctx context.Context, 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(ctx context.Context, c clientset.Interface, ss *appsv1.StatefulSet) *v1.PodList
GetPodList gets the current Pods in ss.
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(name string) v1.PersistentVolumeClaim
NewStatefulSetPVC returns a PersistentVolumeClaim named name, for testing StatefulSets.
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(ctx context.Context, c clientset.Interface, ss *appsv1.StatefulSet)
Restart scales ss to 0 and then back to its previous number of replicas.
func ResumeNextPod(ctx context.Context, 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(ctx context.Context, c clientset.Interface, ss *appsv1.StatefulSet)
Saturate waits for all Pods in ss to become Running and Ready.
func Scale(ctx context.Context, c clientset.Interface, ss *appsv1.StatefulSet, count int32) (*appsv1.StatefulSet, error)
Scale scales ss to count replicas.
func SortStatefulPods(pods *v1.PodList)
SortStatefulPods sorts pods by their ordinals
func UpdateReplicas(ctx context.Context, c clientset.Interface, ss *appsv1.StatefulSet, count int32)
UpdateReplicas updates the replicas of ss to count.
func WaitForPodReady(ctx context.Context, 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(ctx context.Context, 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(ctx context.Context, c clientset.Interface, numStatefulPods int32, ss *appsv1.StatefulSet)
WaitForRunningAndReady waits for numStatefulPods in ss to be Running and Ready.
func WaitForState(ctx context.Context, 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 WaitForStatusAvailableReplicas(ctx context.Context, c clientset.Interface, ss *appsv1.StatefulSet, expectedReplicas int32)
WaitForStatusAvailableReplicas waits for the ss.Status.Available to be equal to expectedReplicas
func WaitForStatusReadyReplicas(ctx context.Context, c clientset.Interface, ss *appsv1.StatefulSet, expectedReplicas int32)
WaitForStatusReadyReplicas waits for the ss.Status.ReadyReplicas to be equal to expectedReplicas
func WaitForStatusReplicas(ctx context.Context, c clientset.Interface, ss *appsv1.StatefulSet, expectedReplicas int32)
WaitForStatusReplicas waits for the ss.Status.Replicas to be equal to expectedReplicas
