Functions

func StartConfigManager

func StartConfigManager(stopCh <-chan struct{}, kc kubernetes.Interface) error

func UpdateNodeGPUInfo

func UpdateNodeGPUInfo(nodeName string, uuid2mem *map[string]string)

Types

type ClientStatus

type ClientStatus string

const (
	ClientReady    ClientStatus = "Ready"
	ClientNotReady ClientStatus = "NotReady"
)

type Controller

type Controller struct {
	// contains filtered or unexported fields
}

func NewController

func NewController(
	kubeclientset kubernetes.Interface,
	kubeshareclientset clientset.Interface,
	podInformer coreinformers.PodInformer,
	kubeshareInformer informers.SharePodInformer) *Controller

NewController returns a new sample controller

func (*Controller) Run

func (c *Controller) Run(threadiness int, stopCh <-chan struct{}) error

Run will set up the event handlers for types we are interested in, as well as syncing informer caches and starting workers. It will block until stopCh is closed, at which point it will shutdown the workqueue and wait for workers to finish processing their current work items.

type GPUInfo

type GPUInfo struct {
	UUID    string
	Usage   float64
	Mem     int64
	PodList *list.List
}

type NodeInfo

type NodeInfo struct {
	// GPUID -> GPU
	GPUID2GPU map[string]*GPUInfo
	// UUID -> Port (string)
	UUID2Port map[string]string

	// port in use
	PodManagerPortBitmap *bitmap.RRBitmap
	PodIP                string
}

type NodeStatus

type NodeStatus struct {
	Conn          net.Conn
	LastHeartbeat time.Time
	ClientStatus  ClientStatus
}

type PodRequest

type PodRequest struct {
	Key            string
	Request        float64
	Limit          float64
	Memory         int64
	PodManagerPort int
}

func FindInQueue

func FindInQueue(key string, pl *list.List) (*PodRequest, bool)
