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

KeyToNamespacedKey prefixes the given index key with a namespace for use in field selector indexes.

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

func (c *CacheReader) Get(_ context.Context, key client.ObjectKey, out runtime.Object) error

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

func (*CacheReader) List

func (c *CacheReader) List(ctx context.Context, opts *client.ListOptions, out runtime.Object) error

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

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) *InformersMap

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

func (*InformersMap) Get

func (m *InformersMap) Get(gvk schema.GroupVersionKind, obj runtime.Object) (*MapEntry, error)

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(stop <-chan struct{}) error

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

func (*InformersMap) WaitForCacheSync

func (m *InformersMap) WaitForCacheSync(stop <-chan struct{}) bool

WaitForCacheSync waits until all the caches have been 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
