Functions

func FieldIndexName

func FieldIndexName(field string) string

FieldIndexName constructs the name of the index over the given field, for use with an indexer.

func KeyToNamespacedKey

func KeyToNamespacedKey(ns string, baseKey string) string

Types

type CacheReader

type CacheReader struct {
	// contains filtered or unexported fields
}

CacheReader wraps a cache.Index to implement the client.CacheReader interface for a single type.

func (*CacheReader) Get

Get checks the indexer for the object and writes a copy of it if found.

func (*CacheReader) List

List lists items out of the indexer and writes them to out.

type DisableDeepCopyByGVK added in v0.10.0

type DisableDeepCopyByGVK map[schema.GroupVersionKind]bool

DisableDeepCopyByGVK associate a GroupVersionKind to disable DeepCopy during get or list from cache.

func (DisableDeepCopyByGVK) IsDisabled added in v0.10.0

func (disableByGVK DisableDeepCopyByGVK) IsDisabled(gvk schema.GroupVersionKind) bool

IsDisabled returns whether a GroupVersionKind is disabled DeepCopy.

type InformersMap

type InformersMap struct {

	// Scheme maps runtime.Objects to GroupVersionKinds
	Scheme *runtime.Scheme
	// contains filtered or unexported fields
}

InformersMap create and caches Informers for (runtime.Object, schema.GroupVersionKind) pairs. It uses a standard parameter codec constructed based on the given generated Scheme.

func NewInformersMap

func NewInformersMap(config *rest.Config,
	scheme *runtime.Scheme,
	mapper meta.RESTMapper,
	resync time.Duration,
	namespace string,
	selectors SelectorsByGVK,
	disableDeepCopy DisableDeepCopyByGVK,
) *InformersMap

NewInformersMap creates a new InformersMap that can create informers for both structured and unstructured objects.

func (*InformersMap) Get

Get will create a new Informer and add it to the map of InformersMap if none exists. Returns the Informer from the map.

func (*InformersMap) Start

func (m *InformersMap) Start(ctx context.Context) error

Start calls Run on each of the informers and sets started to true. Blocks on the context.

func (*InformersMap) WaitForCacheSync

func (m *InformersMap) WaitForCacheSync(ctx context.Context) bool

WaitForCacheSync waits until all the caches have been started and synced.

type MapEntry

type MapEntry struct {
	// Informer is the cached informer
	Informer cache.SharedIndexInformer

	// CacheReader wraps Informer and implements the CacheReader interface for a single type
	Reader CacheReader
}

MapEntry contains the cached data for an Informer.

type Selector added in v0.9.0

type Selector struct {
	Label labels.Selector
	Field fields.Selector
}

Selector specify the label/field selector to fill in ListOptions.

func (Selector) ApplyToList added in v0.9.0

func (s Selector) ApplyToList(listOpts *metav1.ListOptions)

ApplyToList fill in ListOptions LabelSelector and FieldSelector if needed.

type SelectorsByGVK added in v0.9.0

type SelectorsByGVK map[schema.GroupVersionKind]Selector

SelectorsByGVK associate a GroupVersionKind to a field/label selector.
