Types

type EndpointSynchronizer

type EndpointSynchronizer struct{}

EndpointSynchronizer currently is an empty type, which wraps around syncing of CiliumEndpoint resources.

func (*EndpointSynchronizer) DeleteK8sCiliumEndpointSync

func (epSync *EndpointSynchronizer) DeleteK8sCiliumEndpointSync(e *endpoint.Endpoint)

DeleteK8sCiliumEndpointSync replaces the endpoint controller to remove the CEP from Kubernetes once the endpoint is stopped / removed from the Cilium agent.

func (*EndpointSynchronizer) RunK8sCiliumEndpointSync

func (epSync *EndpointSynchronizer) RunK8sCiliumEndpointSync(e *endpoint.Endpoint, conf endpoint.EndpointStatusConfiguration)

RunK8sCiliumEndpointSync starts a controller that synchronizes the endpoint to the corresponding k8s CiliumEndpoint CRD. It is expected that each CEP has 1 controller that updates it, and a local copy is retained and only updates are pushed up. CiliumEndpoint objects have the same name as the pod they represent.

type K8sWatcher

type K8sWatcher struct {

	// K8sSvcCache is a cache of all Kubernetes services and endpoints
	K8sSvcCache k8s.ServiceCache
	// contains filtered or unexported fields
}

func NewK8sWatcher

func NewK8sWatcher(
	endpointManager endpointManager,
	nodeDiscoverManager nodeDiscoverManager,
	policyManager policyManager,
	policyRepository policyRepository,
	svcManager svcManager,
	datapath datapath.Datapath,
) *K8sWatcher

func (*K8sWatcher) DeleteHostPortMapping

func (k *K8sWatcher) DeleteHostPortMapping(pod *slim_corev1.Pod, podIPs []string) error

func (*K8sWatcher) EnableK8sWatcher

func (k *K8sWatcher) EnableK8sWatcher(queueSize uint) error

EnableK8sWatcher watches for policy, services and endpoint changes on the Kubernetes api server defined in the receiver's daemon k8sClient. queueSize specifies the queue length used to serialize k8s events.

func (*K8sWatcher) GetAPIGroups

func (k *K8sWatcher) GetAPIGroups() []string

func (*K8sWatcher) GetCachedNamespace

func (k *K8sWatcher) GetCachedNamespace(namespace string) (*slim_corev1.Namespace, error)

GetCachedNamespace returns a namespace from the local store.

func (*K8sWatcher) GetCachedPod

func (k *K8sWatcher) GetCachedPod(namespace, name string) (*slim_corev1.Pod, error)

GetCachedPod returns a pod from the local store. Depending if the Cilium agent flag `option.Config.K8sEventHandover` this function might only return local pods. If `option.Config.K8sEventHandover` is:

• true: returns only local pods received by the pod watcher.
• false: returns any pod in the cluster received by the pod watcher.

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() <-chan struct{}

InitK8sSubsystem returns a channel for which it will be closed when all caches essential for daemon are synchronized.

func (*K8sWatcher) K8sEventProcessed

func (k *K8sWatcher) K8sEventProcessed(scope string, action string, status bool)

K8sEventProcessed is called to do metrics accounting for each processed Kubernetes event

func (*K8sWatcher) K8sEventReceived

func (k *K8sWatcher) K8sEventReceived(scope string, action string, valid, equal bool)

K8sEventReceived does metric accounting for each received Kubernetes event

func (*K8sWatcher) RunK8sServiceHandler

func (k *K8sWatcher) RunK8sServiceHandler()

func (*K8sWatcher) WaitForCacheSync

func (k *K8sWatcher) WaitForCacheSync(resourceNames ...string)

WaitForCacheSync waits for k8s caches to be synchronized for the given resource. Returns once all resourcesNames are synchronized with cilium-agent.
