Types

type Binder

type Binder interface {
	Bind(task *v1.Pod, hostname string) error
}

type Cache

type Cache interface {
	// Run start informer
	Run(stopCh <-chan struct{})

	// Snapshot deep copy overall cache information into snapshot
	Snapshot() *api.ClusterInfo

	// SchedulerConf return the property of scheduler configuration
	LoadSchedulerConf(path string) (map[string]string, error)

	// WaitForCacheSync waits for all cache synced
	WaitForCacheSync(stopCh <-chan struct{}) bool

	// Bind binds Task to the target host.
	// TODO(jinzhej): clean up expire Tasks.
	Bind(task *api.TaskInfo, hostname string) error

	Evict(task *api.TaskInfo) error
}

Cache collects pods/nodes/queues information and provides information snapshot

func New

func New(config *rest.Config, schedulerName string) Cache

New returns a Cache implementation.

type Evictor

type Evictor interface {
	Evict(pod *v1.Pod) error
}

type SchedulerCache

type SchedulerCache struct {
	sync.Mutex

	Binder  Binder
	Evictor Evictor

	Jobs  map[arbapi.JobID]*arbapi.JobInfo
	Nodes map[string]*arbapi.NodeInfo
	// contains filtered or unexported fields
}
