Functions ¶

func Match ¶

func Match(ds *extensions.DaemonSet, history *apps.ControllerRevision) (bool, error)

Match check if the given DaemonSet's template matches the template stored in the given history.

func NewPod ¶

func NewPod(ds *extensions.DaemonSet, nodeName string) *v1.Pod

func Predicates ¶

func Predicates(pod *v1.Pod, nodeInfo *schedulercache.NodeInfo) (bool, []algorithm.PredicateFailureReason, error)

Predicates checks if a DaemonSet's pod can be scheduled on a node using GeneralPredicates and PodToleratesNodeTaints predicate

Types ¶

type DaemonSetsController ¶

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

DaemonSetsController is responsible for synchronizing DaemonSet objects stored in the system with actual running pods.

func NewDaemonSetsController ¶

func NewDaemonSetsController(daemonSetInformer extensionsinformers.DaemonSetInformer, historyInformer appsinformers.ControllerRevisionInformer, podInformer coreinformers.PodInformer, nodeInformer coreinformers.NodeInformer, kubeClient clientset.Interface) *DaemonSetsController

func (*DaemonSetsController) Run ¶

func (dsc *DaemonSetsController) Run(workers int, stopCh <-chan struct{})

Run begins watching and syncing daemon sets.
