每次调用 runOnce 的过程如下面调度流程图所示：
- OpenSession： 获得这次调度过程的上下文，主要是对 cache 的信息（JobInfos，NodeInfos）做一次 snapshot，然后注册不同 actions 的 plugins。
- enqueue：这个 action 目的是更新一次集群的可提供的资源和待调度 job 的状态，如果 job 里面所有的 task 所需要的资源比集群空余资源小，就会把 job.PodGroup.Status.Phase 从 PodGroupPending 置为 PodGroupInqueue。从这里可以看出 volcano 是以 job 为单位进行调度准入的。
- allocate：这个 action 是调度的的主逻辑，对应 kube-scheduler 的调度和绑定这两步。不过，这里以 task 为单位进行，也是通过预选（PredicateNodes），优选（PrioritizeNodes）的步骤筛选合适的 node，然后对 task 和 node 进行绑定。
- preempt：抢占 actions 是可选的，不过跟 kube-scheduler 的抢占不同的是，不会抢占已经调度完成的 tasks，只会尝试从其他调度队列中的 jobs 或者是同一调度队列的 jobs 中抢占资源（根据 jobs 的优先级抢占）。如果希望抢占已经调度的资源，可以开启另外一个 action reclaim ，会尝试抢占其他低优先级队列中的已经调度 jobs 的资源。
- backfill：这个 actions 我认为是 volcano 比较特别的一个功能，主要是对前面提到还在 pending 中的 jobs 预留资源，因为在集群资源紧张的时候，有可能还没等到有足够的资源启动 job 所有的 tasks，资源就被分配掉了。backfill 会尝试看到资源就申请占用着，等到 jobs 启动的条件足够再退出来让给 job。
volcano调度流程图
代码流程图
说明：
（1）在每轮session调度期间，使用的都是缓存中的数据，如果这个时候集群资源更新了，当前session中的数据不会更新
（2）enqueue的作用就是，根据当前集群资源情况预先筛选出一部分作业。集群资源更新相关的代码都要在这里修改。
（3）allocate负责真正的pod 调度过程。调度逻辑相关的代码需要在这里修改。

调度器的本质还是给所有没有绑定到节点上的pod找到合适的节点并绑定上去，但是为了实现gang调度、抢占、资源预留等功能，不能跟k8s的调度器一样通过watch到的pod事件来触发调度（大多数情况下，每一个pod的调度都是单pod最优），所以volcano的调度器采用的是周期性全局调度的方式。我们在看volcano的调度器代码时也能够看到调度逻辑也是这样的思路：
- list-watch的是PodGroup和Node
- 周期性创建一个全局调度的Session，对集群做一次快照
- 在每一个Session中，根据配置的调度算法和策略对快照中的所有PodGroup进行调度
// Scheduler watches for new unscheduled pods for volcano. It attempts to find // nodes that they fit on and writes bindings back to the api server. type Scheduler struct { cache schedcache.Cache // Cache是一个接口，实现了这个接口的是SchedulerCache，所有调度资源的缓存 actions []framework.Action // 调度器的配置文件中设置的每一轮调度的处理逻辑，有enqueue, allocate, backfill等 plugins []conf.Tier // 调度器的配置文件中设置的调度算法的各个层级的算法集合 configurations []conf.Configuration // 调度器每个Action对应的参数 schedulerConf string // 调度器配置文件路径 schedulePeriod time.Duration // 调度器的调度周期，默认1s }
一个默认的配置文件如下：
scheduler/util.go
var defaultSchedulerConf = ` actions: "enqueue, allocate, backfill" tiers: - plugins: - name: priority - name: gang - plugins: - name: drf - name: predicates - name: proportion - name: nodeorder `
