Types

type Cache

type Cache interface {
	// Cache implements the client CacheReader
	client.Reader

	// Cache implements InformersMap
	Informers
}

Cache implements CacheReader by reading objects from a cache populated by InformersMap

func New

func New(config *rest.Config, opts Options) (Cache, error)

New initializes and returns a new Cache

type Informers

type Informers interface {
	// GetInformer fetches or constructs an informer for the given object that corresponds to a single
	// API kind and resource.
	GetInformer(obj runtime.Object) (toolscache.SharedIndexInformer, error)

	// GetInformerForKind is similar to GetInformer, except that it takes a group-version-kind, instead
	// of the underlying object.
	GetInformerForKind(gvk schema.GroupVersionKind) (toolscache.SharedIndexInformer, error)

	// Start runs all the informers known to this cache until the given channel is closed.
	// It blocks.
	Start(stopCh <-chan struct{}) error

	// WaitForCacheSync waits for all the caches to sync.  Returns false if it could not sync a cache.
	WaitForCacheSync(stop <-chan struct{}) bool

	// IndexField adds an index with the given field name on the given object type
	// by using the given function to extract the value for that field.  If you want
	// compatibility with the Kubernetes API server, only return one key, and only use
	// fields that the API server supports.  Otherwise, you can return multiple keys,
	// and "equality" in the field selector means that at least one key matches the value.
	IndexField(obj runtime.Object, field string, extractValue client.IndexerFunc) error
}

Informers knows how to create or fetch informers for different group-version-kinds. It's safe to call GetInformer from multiple threads.

type Options

type Options struct {
	// Scheme is the scheme to use for mapping objects to GroupVersionKinds
	Scheme *runtime.Scheme

	// Mapper is the RESTMapper to use for mapping GroupVersionKinds to Resources
	Mapper meta.RESTMapper

	// Resync is the resync period. Defaults to defaultResyncTime.
	Resync *time.Duration
}

Options are the optional arguments for creating a new InformersMap object
