Types ¶
type Controller ¶
type Controller struct {
// contains filtered or unexported fields
}
Controller is the controller that recommends resources to the pods. For each Pod Scale assigned to the recommender, it will have a pod saved in a list. Every x seconds, the recommender polls the metrics from the pod by using an http request. For pod metrics it retrieves, it computes the new resources to assign to the pod.
func NewController ¶
func NewController(kubernetesClientset *kubernetes.Clientset, podScalesClientset podscalesclientset.Interface, informers informers.Informers, in chan types.NodeScales) *Controller
NewController returns a new sample controller
func (*Controller) AtomicResourceUpdate ¶
func (c *Controller) AtomicResourceUpdate(pod *corev1.Pod, podScale *v1beta1.PodScale) (*corev1.Pod, *v1beta1.PodScale, error)
AtomicResourceUpdate updates a Pod and its PodScale consistently in order to keep synchronized the two resources. Before performing the real update it runs a request in dry-run and it checks for any potential error
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.
func (*Controller) Shutdown ¶
func (c *Controller) Shutdown()
Shutdown is called when the controller has finished its work
