Overview ¶
Package subscriber implements a mechanism to represent K8s watcher subscribers and allows K8s events to objects / resources to notify their respective subscribers. The intent is to allow the K8s watchers to consolidate all the event handling from various subsystems into one place.

Types ¶
type CESHandler ¶
type CESHandler interface {
OnAdd(ces *cilium_v2a1.CiliumEndpointSlice)
OnUpdate(oldCES, newCES *cilium_v2a1.CiliumEndpointSlice)
OnDelete(ces *cilium_v2a1.CiliumEndpointSlice)
}
CESHandler is implemented by event handlers responding to CiliumEndpointSlice events.
type CESList ¶
type CESList struct {
// contains filtered or unexported fields
}
CESList holds the CES subscribers to any CiliumEndpointSlice resource / object changes in the K8s watchers.
func (*CESList) NotifyAdd ¶
func (l *CESList) NotifyAdd(ces *cilium_v2a1.CiliumEndpointSlice)
NotifyAdd notifies all the subscribers of an add event to an object.
func (*CESList) NotifyDelete ¶
func (l *CESList) NotifyDelete(ces *cilium_v2a1.CiliumEndpointSlice)
NotifyDelete notifies all the subscribers of a delete event to an object.
func (*CESList) NotifyUpdate ¶
func (l *CESList) NotifyUpdate(oldCES, newCES *cilium_v2a1.CiliumEndpointSlice)
NotifyUpdate notifies all the subscribers of an update event to an object.
func (*CESList) Register ¶
func (l *CESList) Register(c CESHandler)
Register registers the CES event handler as a subscriber.
type RawChain ¶
type RawChain struct {
// contains filtered or unexported fields
}
RawChain holds the raw subscribers to any K8s resource / object changes in the K8s watchers.
RawChain itself is an implementation of cache.ResourceEventHandler with an additional Register method for attaching children subscribers to the chain.
func (*RawChain) OnDelete ¶
func (l *RawChain) OnDelete(obj interface{})
NotifyDelete notifies all the subscribers of an update event to an object.
func (*RawChain) OnUpdate ¶
func (l *RawChain) OnUpdate(oldObj, newObj interface{})
NotifyUpdate notifies all the subscribers of an update event to an object.
func (*RawChain) Register ¶
func (l *RawChain) Register(cb cache.ResourceEventHandler)
Register registers the raw event handler as a subscriber.
type Service ¶
type Service interface {
OnAddService(*slim_corev1.Service) error
OnUpdateService(oldObj, newObj *slim_corev1.Service) error
OnDeleteService(*slim_corev1.Service) error
}
Service is implemented by event handlers responding to K8s Service events.
type ServiceChain ¶
type ServiceChain struct {
// contains filtered or unexported fields
}
ServiceChain holds the subscriber.Service implementations that are notified when reacting to K8s Service resource / object changes in the K8s watchers.
ServiceChain itself is an implementation of subscriber.Service with an additional Register method for attaching children subscribers to the chain.
func (*ServiceChain) OnAddService ¶
func (l *ServiceChain) OnAddService(svc *slim_corev1.Service) error
OnAddService notifies all the subscribers of an add event to a service.
func (*ServiceChain) OnDeleteService ¶
func (l *ServiceChain) OnDeleteService(svc *slim_corev1.Service) error
OnDeleteService notifies all the subscribers of an update event to a service.
func (*ServiceChain) OnUpdateService ¶
func (l *ServiceChain) OnUpdateService(oldSvc, newSvc *slim_corev1.Service) error
OnUpdateService notifies all the subscribers of an update event to a service.
func (*ServiceChain) Register ¶
func (l *ServiceChain) Register(s Service)
Register registers ServiceHandler as a subscriber for reacting to Service objects into the list.
