Types

type Extension

type Extension interface {
	UpdateHostStatus(error, *unstructured.Unstructured, interface{}) error
	GetHostFromObject(metav1.Object) *types.NamespacedName
	SetSynchronizerToObject(metav1.Object, *types.NamespacedName) error
	SetHostToObject(metav1.Object, types.NamespacedName, *types.NamespacedName) error

	IsObjectOwnedBySynchronizer(metav1.Object, *types.NamespacedName) bool
	IsIgnoredGroupKind(schema.GroupKind) bool
}

Extension defines the extension features of synchronizer

type KubeSynchronizer

type KubeSynchronizer struct {
	Interval     int
	LocalClient  client.Client
	RemoteClient client.Client

	DynamicClient  dynamic.Interface
	KubeResources  map[schema.GroupVersionKind]*ResourceMap
	SynchronizerID *types.NamespacedName
	Extension      Extension
	// contains filtered or unexported fields
}

KubeSynchronizer handles resources to a kube endpoint
