Types

type NetworkRoutingController

type NetworkRoutingController struct {
	MetricsEnabled bool

	CNIFirewallSetup *sync.Cond

	NodeEventHandler      cache.ResourceEventHandler
	ServiceEventHandler   cache.ResourceEventHandler
	EndpointsEventHandler cache.ResourceEventHandler
	// contains filtered or unexported fields
}

NetworkRoutingController is struct to hold necessary information required by controller

func NewNetworkRoutingController

func NewNetworkRoutingController(clientset kubernetes.Interface,
	kubeRouterConfig *options.KubeRouterConfig,
	nodeInformer cache.SharedIndexInformer, svcInformer cache.SharedIndexInformer,
	epInformer cache.SharedIndexInformer, ipsetMutex *sync.Mutex) (*NetworkRoutingController, error)

NewNetworkRoutingController returns new NetworkRoutingController object

func (*NetworkRoutingController) AddPolicies

func (nrc *NetworkRoutingController) AddPolicies() error

AddPolicies adds BGP import and export policies

func (*NetworkRoutingController) Cleanup

func (nrc *NetworkRoutingController) Cleanup()

Cleanup performs the cleanup of configurations done

func (*NetworkRoutingController) OnEndpointsAdd

func (nrc *NetworkRoutingController) OnEndpointsAdd(obj interface{})

OnEndpointsAdd handles endpoint add events from apiserver This method calls OnEndpointsUpdate with the addition of updating BGP export policies Calling AddPolicies here covers the edge case where AddPolicies fails in OnServiceUpdate because the corresponding Endpoint resource for the Service was not created yet.

func (*NetworkRoutingController) OnEndpointsUpdate

func (nrc *NetworkRoutingController) OnEndpointsUpdate(obj interface{})

OnEndpointsUpdate handles the endpoint updates from the kubernetes API server

func (*NetworkRoutingController) OnNodeUpdate

func (nrc *NetworkRoutingController) OnNodeUpdate(_ interface{})

OnNodeUpdate Handle updates from Node watcher. Node watcher calls this method whenever there is new node is added or old node is deleted. So peer up with new node and drop peering from old node

func (*NetworkRoutingController) OnServiceCreate

func (nrc *NetworkRoutingController) OnServiceCreate(obj interface{})

OnServiceCreate handles new service create event from the kubernetes API server

func (*NetworkRoutingController) OnServiceDelete

func (nrc *NetworkRoutingController) OnServiceDelete(obj interface{})

OnServiceDelete handles the service delete updates from the kubernetes API server

func (*NetworkRoutingController) OnServiceUpdate

func (nrc *NetworkRoutingController) OnServiceUpdate(objNew interface{}, objOld interface{})

OnServiceUpdate handles the service relates updates from the kubernetes API server

func (*NetworkRoutingController) Run

func (nrc *NetworkRoutingController) Run(healthChan chan<- *healthcheck.ControllerHeartbeat, stopCh <-chan struct{},
	wg *sync.WaitGroup)

Run runs forever until we are notified on stop channel
