示例1: UpdateRSWithRetries

// UpdateRSWithRetries updates a RS with given applyUpdate function. Note that RS not found error is ignored.
// The returned bool value can be used to tell if the RS is actually updated.
func UpdateRSWithRetries(rsClient unversionedextensions.ReplicaSetInterface, rs *extensions.ReplicaSet, applyUpdate updateRSFunc) (*extensions.ReplicaSet, bool, error) {
	var err error
	var rsUpdated bool
	oldRs := rs
	if err = wait.Poll(10*time.Millisecond, 1*time.Minute, func() (bool, error) {
		rs, err = rsClient.Get(oldRs.Name)
		if err != nil {
			return false, err
		}
		// Apply the update, then attempt to push it to the apiserver.
		if err = applyUpdate(rs); err != nil {
			return false, err
		}
		if rs, err = rsClient.Update(rs); err == nil {
			// Update successful.
			return true, nil
		}
		// TODO: don't retry on perm-failed errors and handle them gracefully
		// Update could have failed due to conflict error. Try again.
		return false, nil
	}); err == nil {
		// When there's no error, we've updated this RS.
		rsUpdated = true
	}

	// Handle returned error from wait poll
	if err == wait.ErrWaitTimeout {
		err = fmt.Errorf("timed out trying to update RS: %+v", oldRs)
	}
	// Ignore the RS not found error, but the RS isn't updated.
	if errors.IsNotFound(err) {
		glog.V(4).Infof("%s %s/%s is not found, skip updating it.", oldRs.Kind, oldRs.Namespace, oldRs.Name)
		err = nil
	}
	// Ignore the precondition violated error, but the RS isn't updated.
	if err == errorsutil.ErrPreconditionViolated {
		glog.V(4).Infof("%s %s/%s precondition doesn't hold, skip updating it.", oldRs.Kind, oldRs.Namespace, oldRs.Name)
		err = nil
	}

	// If the error is non-nil the returned RS cannot be trusted; if rsUpdated is false, the contoller isn't updated;
	// if the error is nil and rsUpdated is true, the returned RS contains the applied update.
	return rs, rsUpdated, err
}
