Functions

func HasIdleAt

func HasIdleAt(svc *kapi.Service) bool

HasIdleAt returns true if the service annotation map contains a key like "*/idled-at"

func IsOnGracePeriod

func IsOnGracePeriod(svc *kapi.Service) bool

IsOnGracePeriod return true if the service has been unidled less than 30s (grace period) ago.

func NewController

func NewController(recorder record.EventRecorder, serviceInformer cache.SharedIndexInformer, sbClient libovsdbclient.Client) (*unidlingController, error)

NewController creates a new unidling controller

func NewUnidledAtController

func NewUnidledAtController(k kube.Interface, serviceInformer cache.SharedIndexInformer) (*unidledAtController, error)

NewUnidledAtController installs a controller on the passed informer. Whenever a service annotation like "*/idled-at" is removed from a service, it sets "k8s.ovn.org/unidled-at" with the current time, indicating the point in time the service has been unidled.
