示例1: tick

// tick attempts to schedule the queue.
func (s *Scheduler) tick(ctx context.Context) {
	tasksByCommonSpec := make(map[string]map[string]*api.Task)
	schedulingDecisions := make(map[string]schedulingDecision, s.unassignedTasks.Len())

	var next *list.Element
	for e := s.unassignedTasks.Front(); e != nil; e = next {
		next = e.Next()
		t := s.allTasks[e.Value.(*api.Task).ID]
		if t == nil || t.NodeID != "" {
			// task deleted or already assigned
			s.unassignedTasks.Remove(e)
			continue
		}

		// Group common tasks with common specs by marshalling the spec
		// into taskKey and using it as a map key.
		// TODO(aaronl): Once specs are versioned, this will allow a
		// much more efficient fast path.
		fieldsToMarshal := api.Task{
			ServiceID: t.ServiceID,
			Spec:      t.Spec,
		}
		marshalled, err := fieldsToMarshal.Marshal()
		if err != nil {
			panic(err)
		}
		taskGroupKey := string(marshalled)

		if tasksByCommonSpec[taskGroupKey] == nil {
			tasksByCommonSpec[taskGroupKey] = make(map[string]*api.Task)
		}
		tasksByCommonSpec[taskGroupKey][t.ID] = t
		s.unassignedTasks.Remove(e)
	}

	for _, taskGroup := range tasksByCommonSpec {
		s.scheduleTaskGroup(ctx, taskGroup, schedulingDecisions)
	}

	_, failed := s.applySchedulingDecisions(ctx, schedulingDecisions)
	for _, decision := range failed {
		s.allTasks[decision.old.ID] = decision.old

		nodeInfo, err := s.nodeSet.nodeInfo(decision.new.NodeID)
		if err == nil && nodeInfo.removeTask(decision.new) {
			s.nodeSet.updateNode(nodeInfo)
		}

		// enqueue task for next scheduling attempt
		s.enqueue(decision.old)
	}
}
