ENIChain *subscriber.ENIChain // contains filtered or unexported fields }
func NewK8sWatcher ¶
func NewK8sWatcher() *K8sWatcher
func (*K8sWatcher) GetAPIGroups ¶
func (k *K8sWatcher) GetAPIGroups() []string
func (*K8sWatcher) GetK8sNode ¶
GetK8sNode returns the *local Node* from the local store.
func (*K8sWatcher) GetStore ¶
func (k *K8sWatcher) GetStore(name string) cache.Store
GetStore returns the k8s cache store for the given resource name.
func (*K8sWatcher) InitK8sSubsystem ¶
func (k *K8sWatcher) InitK8sSubsystem(ctx context.Context, cachesSynced chan struct{})
InitK8sSubsystem takes a channel for which it will be closed when all caches essential for daemon are synchronized. To be called after WaitForCRDsToRegister() so that all needed CRDs have already been registered.
func (*K8sWatcher) K8sEventProcessed ¶
func (k *K8sWatcher) K8sEventProcessed(scope, action string, status bool)
K8sEventProcessed is called to do metrics accounting for each processed Kubernetes event
func (*K8sWatcher) K8sEventReceived ¶
func (k *K8sWatcher) K8sEventReceived(apiResourceName, scope, action string, valid, equal bool)
K8sEventReceived does metric accounting for each received Kubernetes event, as well as notifying of events for k8s resources synced.
func (*K8sWatcher) NewCCEEndpointClient ¶
func (k *K8sWatcher) NewCCEEndpointClient() *CCEEndpointClient
func (*K8sWatcher) NewENIClient ¶
func (k *K8sWatcher) NewENIClient() *ENIClient
func (*K8sWatcher) NewPodClient ¶
func (k *K8sWatcher) NewPodClient() *PodClient
func (*K8sWatcher) NodesInit ¶
func (k *K8sWatcher) NodesInit(k8sClient *k8s.K8sClient)
func (*K8sWatcher) RegisterCCEEndpointSubscriber ¶
func (k *K8sWatcher) RegisterCCEEndpointSubscriber(s subscriber.CCEEndpoint)
RegisterCCEEndpointSubscriber allows registration of subscriber.CCEEndpoint implementations. On CCEEndpoint events all registered subscriber.CCEEndpoint implementations will have their event handling methods called in order of registration.
func (*K8sWatcher) RegisterENISubscriber ¶
func (k *K8sWatcher) RegisterENISubscriber(s subscriber.ENI)
RegisterENISubscriber allows registration of subscriber.ENI implementations. On ENI events all registered subscriber.ENI implementations will have their event handling methods called in order of registration.
func (*K8sWatcher) RegisterNetResourceSetSubscriber ¶
func (k *K8sWatcher) RegisterNetResourceSetSubscriber(s subscriber.NetResourceSet)
RegisterNetResourceSetSubscriber allows registration of subscriber.NetResourceSet implementations. On NetResourceSet events all registered subscriber.NetResourceSet implementations will have their event handling methods called in order of registration.
func (*K8sWatcher) RegisterNodeSubscriber ¶
func (k *K8sWatcher) RegisterNodeSubscriber(s subscriber.Node)
RegisterNodeSubscriber allows registration of subscriber.Node implementations. On k8s Node events all registered subscriber.Node implementations will have their event handling methods called in order of registration.
func (*K8sWatcher) WaitForCRDsToRegister ¶
func (k *K8sWatcher) WaitForCRDsToRegister(ctx context.Context) error
WaitForCRDsToRegister will wait for the CCE Operator to register the CRDs with the apiserver. This step is required before launching the full K8s watcher, as those resource controllers need the resources to be registered with K8s first.
func (*K8sWatcher) WaitForCacheSync ¶
func (k *K8sWatcher) WaitForCacheSync(resourceNames ...string)
WaitForCacheSync blocks until the given resources have been synchronized from k8s. Note that if the controller for a resource has not been started, the wait for that resource returns immediately. If it is required that the resource exists and is actually synchronized, the caller must ensure the controller for that resource has been started before calling WaitForCacheSync. For most resources this can be done by receiving from controllersStarted channel (<-k.controllersStarted), which is closed after most watchers have been started.
func (*K8sWatcher) WaitForCacheSyncWithTimeout ¶
func (k *K8sWatcher) WaitForCacheSyncWithTimeout(timeout time.Duration, resourceNames ...string) error
WaitForCacheSyncWithTimeout calls WaitForCacheSync to block until given resources have had their caches synced from K8s. This will wait up to the timeout duration after starting or since the last K8s registered watcher event (i.e. each event causes the timeout to be pushed back). Events are recorded using K8sResourcesSynced.Event function. If the timeout is exceeded, an error is returned.
type WatcherConfiguration ¶
type WatcherConfiguration interface { utils.ServiceConfiguration utils.IngressConfiguration }
WatcherConfiguration is the required configuration for enableK8sWatchers
