Kubernetes34--ReplicationController源码--slowStartBatch

在RC数量控制过程中，需要创建一部分Pod对象，调用slowStartBatch方法

successfulCreations, err := slowStartBatch(diff, controller.SlowStartInitialBatchSize, func() error { boolPtr := func(b bool) *bool { return &b } controllerRef := &metav1.OwnerReference{ APIVersion: rsc.GroupVersion().String(), Kind: rsc.Kind, Name: rs.Name, UID: rs.UID, BlockOwnerDeletion: boolPtr(true), Controller: boolPtr(true), } err := rsc.podControl.CreatePodsWithControllerRef(rs.Namespace, &rs.Spec.Template, rs, controllerRef) if err != nil && errors.IsTimeout(err) { // Pod is created but its initialization has timed out. // If the initialization is successful eventually, the // controller will observe the creation via the informer. // If the initialization fails, or if the pod keeps // uninitialized for a long time, the informer will not // receive any update, and the controller will create a new // pod when the expectation expires. return nil } return err }) success
