示例1: initializeCaches

// initializeCaches fills all controller caches with initial data from etcd in
// order to have the caches already filled when first addClaim/addVolume to
// perform initial synchronization of the controller.
func (ctrl *PersistentVolumeController) initializeCaches(volumeSource, claimSource cache.ListerWatcher) {
	volumeListObj, err := volumeSource.List(api.ListOptions{})
	if err != nil {
		glog.Errorf("PersistentVolumeController can't initialize caches: %v", err)
		return
	}
	volumeList, ok := volumeListObj.(*api.List)
	if !ok {
		glog.Errorf("PersistentVolumeController can't initialize caches, expected list of volumes, got: %+v", volumeListObj)
		return
	}
	for _, volume := range volumeList.Items {
		// Ignore template volumes from kubernetes 1.2
		deleted := ctrl.upgradeVolumeFrom1_2(volume.(*api.PersistentVolume))
		if !deleted {
			storeObjectUpdate(ctrl.volumes.store, volume, "volume")
		}
	}
