Functions

func MakeGenerationLabelSelector

func MakeGenerationLabelSelector(om metav1.ObjectMetaAccessor) labels.Selector

MakeGenerationLabelSelector constructs a selector for subresources instantiated at this version of the parent resource. This keys off of the labels populated by MakeGenerationLabels.

func MakeGenerationLabels

func MakeGenerationLabels(om metav1.ObjectMetaAccessor) labels.Set

MakeGenerationLabels constructs a set of labels to apply to subresources instantiated at this version of the parent resource, so that we can efficiently select them.

func MakeOldGenerationLabelSelector

func MakeOldGenerationLabelSelector(om metav1.ObjectMetaAccessor) labels.Selector

MakeOldGenerationLabelSelector constructs a selector for subresources instantiated at an older version of the parent resource. This keys off of the labels populated by MakeGenerationLabels.

func MakeOldVersionLabelSelector

func MakeOldVersionLabelSelector(om metav1.ObjectMetaAccessor) labels.Selector

MakeOldVersionLabelSelector constructs a selector for subresources instantiated at an older version of the parent resource. This keys off of the labels populated by MakeVersionLabels.

func MakeVersionLabelSelector

func MakeVersionLabelSelector(om metav1.ObjectMetaAccessor) labels.Selector

MakeVersionLabelSelector constructs a selector for subresources instantiated at this version of the parent resource. This keys off of the labels populated by MakeVersionLabels.

func MakeVersionLabels

func MakeVersionLabels(om metav1.ObjectMetaAccessor) labels.Set

MakeVersionLabels constructs a set of labels to apply to subresources instantiated at this version of the parent resource, so that we can efficiently select them.

func NewControllerRef

func NewControllerRef(obj OwnerRefable) *metav1.OwnerReference

NewControllerRef creates an OwnerReference pointing to the given controller.

Types

type Accessor

type Accessor interface {
	// Interfaces for metav1.TypeMeta
	GroupVersionKind() schema.GroupVersionKind
	SetGroupVersionKind(gvk schema.GroupVersionKind)

	// Interfaces for runtime.Object
	GetObjectKind() schema.ObjectKind
	DeepCopyObject() runtime.Object

	// Interfaces for metav1.Object
	GetNamespace() string
	SetNamespace(namespace string)
	GetName() string
	SetName(name string)
	GetGenerateName() string
	SetGenerateName(name string)
	GetUID() types.UID
	SetUID(uid types.UID)
	GetResourceVersion() string
	SetResourceVersion(version string)
	GetGeneration() int64
	SetGeneration(generation int64)
	GetSelfLink() string
	SetSelfLink(selfLink string)
	GetCreationTimestamp() metav1.Time
	SetCreationTimestamp(timestamp metav1.Time)
	GetDeletionTimestamp() *metav1.Time
	SetDeletionTimestamp(timestamp *metav1.Time)
	GetDeletionGracePeriodSeconds() *int64
	SetDeletionGracePeriodSeconds(*int64)
	GetLabels() map[string]string
	SetLabels(labels map[string]string)
	GetAnnotations() map[string]string
	SetAnnotations(annotations map[string]string)
	GetInitializers() *metav1.Initializers
	SetInitializers(initializers *metav1.Initializers)
	GetFinalizers() []string
	SetFinalizers(finalizers []string)
	GetOwnerReferences() []metav1.OwnerReference
	SetOwnerReferences([]metav1.OwnerReference)
	GetClusterName() string
	SetClusterName(clusterName string)
}

Accessor is a collection of interfaces from metav1.TypeMeta, runtime.Object and metav1.Object that Kubernetes API types registered with runtime.Scheme must support.

func DeletionHandlingAccessor

func DeletionHandlingAccessor(obj interface{}) (Accessor, error)

DeletionHandlingAccessor tries to convert given interface into Accessor first; and to handle deletion, it try to fetch info from DeletedFinalStateUnknown on failure. The name is a reference to cache.DeletionHandlingMetaNamespaceKeyFunc

type OwnerRefable

type OwnerRefable interface {
	metav1.ObjectMetaAccessor

	// GetGroupVersionKind returns a GroupVersionKind. The name is chosen
	// to avoid collision with TypeMeta's GroupVersionKind() method.
	// See: https://issues.k8s.io/3030
	GetGroupVersionKind() schema.GroupVersionKind
}

OwnerRefable indicates that a particular type has sufficient information to produce a metav1.OwnerReference to an object.
