type Scheduler struct {
	// contains filtered or unexported fields

Scheduler 调度器

func (*Scheduler) Next

func (s *Scheduler) Next() (*job.Job, error)

Next 下一个调度对象

func (*Scheduler) Stop

func (s *Scheduler) Stop()

Stop 停止

type TaskEngine

type TaskEngine struct {
	// contains filtered or unexported fields

TaskEngine 任务引擎 处理任务的执行,结果处理,任务自动调度 TODO:执行记录清理工作

func CreateTaskEngine

func CreateTaskEngine(nodeCluster *node.Cluster, node *nodeclient.HostNode) *TaskEngine

CreateTaskEngine 创建task管理引擎

func (*TaskEngine) AddGroupConfig

func (t *TaskEngine) AddGroupConfig(groupID string, configs map[string]string)

AddGroupConfig 添加组会话配置

func (t *TaskEngine) AddTask(task *model.Task) error

AddTask 添加task 新添加task

func (*TaskEngine) CacheTask

func (t *TaskEngine) CacheTask(task *model.Task)

CacheTask 缓存task

func (*TaskEngine) DependRun

func (t *TaskEngine) DependRun(node string, task, depTask *model.Task, Strategy string) (bool, error)

DependRun 验证依赖任务执行情况

func (*TaskEngine) DependsRun

func (t *TaskEngine) DependsRun(node string, task *model.Task) (bool, error)

DependsRun DependRun

func (*TaskEngine) LoadStaticTask

func (t *TaskEngine) LoadStaticTask()

LoadStaticTask 从文件加载task TODO:动态加载

func (*TaskEngine) PutSchedul

func (t *TaskEngine) PutSchedul(taskID string, nodeID string) (err error)

PutSchedul 发布调度需求,即定义task的某个执行节点 taskID+nodeID = 一个调度单位,保证不重复 node不能为空

func (*TaskEngine) RemoveTask

func (t *TaskEngine) RemoveTask(task *model.Task)

RemoveTask 从缓存移除task

func (*TaskEngine) ScheduleGroup

func (t *TaskEngine) ScheduleGroup(nextGroups *model.TaskGroup, node string) error

type ValidationCriteria

type ValidationCriteria func(string, *model.Task) (bool, error)

ValidationCriteria 在某个节点执行任务,行不行

var AllCouldRun ValidationCriteria = func(string, *model.Task) (bool, error) {
	return true, nil

AllCouldRun 可以执行

var ModeRun ValidationCriteria = func(node string, task *model.Task) (bool, error) {
	if task.RunMode == "OnlyOnce" {
		if status, ok := task.Status[node]; ok {
			if status.CompleStatus == "Success" {
				return false, fmt.Errorf("this job In violation of the task runmode")
	return true, nil

ModeRun 验证任务执行策略
