Types

type ConditionWaiter

type ConditionWaiter[Client any] interface {
	Prepare(context.Context, Client) error
	Poll(context.Context, Client) (bool, error)
}

func WaitForPodConditition

func WaitForPodConditition(namespace string, selector metav1.ListOptions, isOk func(corev1.PodStatus) (bool, error)) ConditionWaiter[*k8s.Clientset]

type PodObserver

type PodObserver struct {
