Types ¶
type Controller ¶
type Controller struct {
// contains filtered or unexported fields
}
Controller listens to Taint changes of DRA devices and Toleration changes of ResourceClaims, then deletes Pods which use ResourceClaims that don't tolerate a NoExecute taint. Pods which have already reached a final state (aka terminated) don't need to be deleted.
All of the logic which identifies pods which need to be evicted runs in the handle* event handlers. They don't call any blocking method. All the blocking calls happen in a tainteviction.TimedWorkerQueue, using the context passed to Run.
The [resourceslicetracker] takes care of applying taints defined in DeviceTaintRules to ResourceSlices. This controller here receives modified ResourceSlices with all applicable taints from that tracker and doesn't need to care about where a taint came from, the DRA driver or a DeviceTaintRule.
func New ¶
func New(c clientset.Interface, podInformer coreinformers.PodInformer, claimInformer resourceinformers.ResourceClaimInformer, sliceInformer resourceinformers.ResourceSliceInformer, taintInformer resourcealphainformers.DeviceTaintRuleInformer, classInformer resourceinformers.DeviceClassInformer, controllerName string) *Controller
New creates a new Controller that will use passed clientset to communicate with the API server. Spawns no goroutines. That happens in Run.
