func DeleteOptionsForeground

func DeleteOptionsForeground() metav1.DeleteOptions

DeleteOptionsForeground creates new delete options that will block until the operation completes.

func DumpCoreDumps

func DumpCoreDumps(_ resource.Context, c cluster.Cluster, workDir string, namespace string, pods ...corev1.Pod)

func DumpDebug

func DumpDebug(ctx resource.Context, c cluster.Cluster, workDir, endpoint, namespace string)

func DumpDeployments

func DumpDeployments(ctx resource.Context, workDir, namespace string)

func DumpPodAgent

func DumpPodAgent(ctx resource.Context, c cluster.Cluster, workDir string, _ string, pods ...corev1.Pod)

func DumpPodEnvoy

func DumpPodEnvoy(ctx resource.Context, c cluster.Cluster, workDir, namespace string, pods ...corev1.Pod)

DumpPodEnvoy will dump Envoy proxy config and clusters in each of the provided pods or all pods in the namespace if none are provided.

func DumpPodEvents

func DumpPodEvents(_ resource.Context, c cluster.Cluster, workDir, namespace string, pods ...corev1.Pod)

DumpPodEvents dumps the pod events for either the provided pods or all pods in the namespace if none are provided.

func DumpPodLogs

func DumpPodLogs(_ resource.Context, c cluster.Cluster, workDir, namespace string, pods ...corev1.Pod)

DumpPodState dumps the pod state for either the provided pods or all pods in the namespace if none are provided.

func DumpPods

func DumpPods(ctx resource.Context, workDir, namespace string, selectors []string, dumpers ...PodDumper)

DumpPods runs each dumper with the selected pods in the given namespace. If selectors is empty, all pods in the namespace will be dumpped. If no dumpers are provided, their resource state, events, container logs and Envoy information will be dumped.

func DumpWebhooks

func DumpWebhooks(ctx resource.Context, workDir string)

func MutatingWebhookConfigurationsExists

func MutatingWebhookConfigurationsExists(a kubernetes.Interface, names []string) bool

MutatingWebhookConfigurationsExists returns true if all the given mutating webhook configs exist.

func NamespaceExists

func NamespaceExists(a kubernetes.Interface, ns string) bool

NamespaceExists returns true if the given namespace exists.

func ValidatingWebhookConfigurationsExists

func ValidatingWebhookConfigurationsExists(a kubernetes.Interface, names []string) bool

ValidatingWebhookConfigurationsExists returns true if all the given validating webhook configs exist.

func WaitForNamespaceDeletion

func WaitForNamespaceDeletion(a kubernetes.Interface, ns string, opts ...retry.Option) error

WaitForNamespaceDeletion waits until a namespace is deleted.

func WaitForSecretToExist

WaitForSecretToExist waits for the given secret up to the given waitTime.

func WaitForSecretToExistOrFail

func WaitForSecretToExistOrFail(t test.Failer, a kubernetes.Interface, namespace, name string,
	waitTime time.Duration,
) *corev1.Secret

WaitForSecretToExistOrFail calls WaitForSecretToExist and fails the given test.Failer if an error occurs.

func WaitUntilPodsAreReady

func WaitUntilPodsAreReady(fetchFunc PodFetchFunc, opts ...retry.Option) ([]corev1.Pod, error)

WaitUntilPodsAreReady waits until the pod with the name/namespace is in ready state.

func WaitUntilServiceEndpointsAreReady
