Types

type GenericInformer

type GenericInformer interface {
	Informer() cache.SharedIndexInformer
	Lister() cache.GenericLister
}

GenericInformer is type of SharedIndexInformer which will locate and delegate to other sharedInformers based on type

type SharedInformerFactory

type SharedInformerFactory interface {
	internalinterfaces.SharedInformerFactory

	// Start initializes all requested informers. They are handled in goroutines
	// which run until the stop channel gets closed.
	Start(stopCh <-chan struct{})

	// Shutdown marks a factory as shutting down. At that point no new
	// informers can be started anymore and Start will return without
	// doing anything.
	//
	// In addition, Shutdown blocks until all goroutines have terminated. For that
	// to happen, the close channel(s) that they were started with must be closed,
	// either before Shutdown gets called or while it is waiting.
	//
	// Shutdown may be called multiple times, even concurrently. All such calls will
	// block until all goroutines have terminated.
	Shutdown()

	// WaitForCacheSync blocks until all started informers' caches were synced
	// or the stop channel gets closed.
	WaitForCacheSync(stopCh <-chan struct{}) map[reflect.Type]bool

	// ForResource gives generic access to a shared informer of the matching type.
	ForResource(resource schema.GroupVersionResource) (GenericInformer, error)

	// InformerFor returns the SharedIndexInformer for obj using an internal
	// client.
	InformerFor(obj runtime.Object, newFunc internalinterfaces.NewInformerFunc) cache.SharedIndexInformer

	Autoscaling() autoscaling.Interface
	Serving() serving.Interface
}

SharedInformerFactory provides shared informers for resources in all known API group versions.

It is typically used like this:

ctx, cancel := context.Background()
defer cancel()
factory := NewSharedInformerFactory(client, resyncPeriod)
defer factory.WaitForStop()    // Returns immediately if nothing was started.
genericInformer := factory.ForResource(resource)
typedInformer := factory.SomeAPIGroup().V1().SomeType()
factory.Start(ctx.Done())          // Start processing these informers.
synced := factory.WaitForCacheSync(ctx.Done())
for v, ok := range synced {
    if !ok {
        fmt.Fprintf(os.Stderr, "caches failed to sync: %v", v)
        return
    }
}

// Creating informers can also be created after Start, but then
// Start must be called again:
anotherGenericInformer := factory.ForResource(resource)
factory.Start(ctx.Done())

func NewFilteredSharedInformerFactory

func NewFilteredSharedInformerFactory(client versioned.Interface, defaultResync time.Duration, namespace string, tweakListOptions internalinterfaces.TweakListOptionsFunc) SharedInformerFactory

NewFilteredSharedInformerFactory constructs a new instance of sharedInformerFactory. Listers obtained via this SharedInformerFactory will be subject to the same filters as specified here. Deprecated: Please use NewSharedInformerFactoryWithOptions instead

func NewSharedInformerFactory

func NewSharedInformerFactory(client versioned.Interface, defaultResync time.Duration) SharedInformerFactory

NewSharedInformerFactory constructs a new instance of sharedInformerFactory for all namespaces.

func NewSharedInformerFactoryWithOptions added in v0.2.0

func NewSharedInformerFactoryWithOptions(client versioned.Interface, defaultResync time.Duration, options ...SharedInformerOption) SharedInformerFactory

NewSharedInformerFactoryWithOptions constructs a new instance of a SharedInformerFactory with additional options.

type SharedInformerOption added in v0.2.0

type SharedInformerOption func(*sharedInformerFactory) *sharedInformerFactory

SharedInformerOption defines the functional option type for SharedInformerFactory.

func WithCustomResyncConfig added in v0.2.0

func WithCustomResyncConfig(resyncConfig map[v1.Object]time.Duration) SharedInformerOption

WithCustomResyncConfig sets a custom resync period for the specified informer types.

func WithNamespace added in v0.2.0

func WithNamespace(namespace string) SharedInformerOption

WithNamespace limits the SharedInformerFactory to the specified namespace.

func WithTweakListOptions added in v0.2.0

func WithTweakListOptions(tweakListOptions internalinterfaces.TweakListOptionsFunc) SharedInformerOption

WithTweakListOptions sets a custom filter on all listers of the configured SharedInformerFactory.
