Functions

func CheckDNSResolver 

func CheckDNSResolver() error

func DeletionHandlingMetaNamespaceKeyFunc 

func DeletionHandlingMetaNamespaceKeyFunc(obj interface{}) (string, error)

func NewMultiTenantPlugin 

func NewMultiTenantPlugin() osdnPolicy

func NewNetworkPolicyPlugin 

func NewNetworkPolicyPlugin() osdnPolicy

func NewOVSController 

func NewOVSController(ovsif ovs.Interface, pluginId int) *ovsController

func NewSingleTenantPlugin 

func NewSingleTenantPlugin() osdnPolicy

func RegisterSharedInformerEventHandlers 

func RegisterSharedInformerEventHandlers(kubeInformers kinternalinformers.SharedInformerFactory,
	addOrUpdateFunc func(interface{}, interface{}, watch.EventType),
	delFunc func(interface{}), resourceName ResourceName)

RegisterSharedInformerEventHandlers registers addOrUpdateFunc and delFunc event handlers with kubernetes shared informers for the given resource name.

func RunEventQueue 

func RunEventQueue(client kcache.Getter, resourceName ResourceName, process ProcessEventFunc)

Run event queue for the given resource. The 'process' function is called repeatedly with each available cache.Delta that describes state changes to an object. If the process function returns an error queued changes for that object are dropped but processing continues with the next available object's cache.Deltas. The error is logged with call stack information.

NOTE: this function will handle DeletedFinalStateUnknown delta objects automatically, which may not always be what you want since the now-deleted object may be stale.

func StartMaster 

func StartMaster(networkConfig osconfigapi.MasterNetworkConfig, osClient *osclient.Client, kClient kclientset.Interface, informers shared.InformerFactory) error

Types

func (e *EgressDNS) Update(policyUID ktypes.UID) (error, bool)

type EgressDNSUpdate

	UID       ktypes.UID
	Namespace string
}

type EventQueue 

type EventQueue struct {
	*cache.DeltaFIFO
	// contains filtered or unexported fields
}

EventQueue is an enhanced DeltaFIFO that provides reliable Deleted deltas even if no knownObjects store is given, and compresses multiple deltas to reduce duplicate events.

Without a store, DeltaFIFO will drop Deleted deltas when its queue is empty because the deleted object is not present in the queue and DeltaFIFO tries to protect against duplicate Deleted deltas resulting from Replace().

To get reliable deletion, a store must be provided, and EventQueue provides one if the caller does not.

func NewEventQueue 

func NewEventQueue(keyFunc cache.KeyFunc) *EventQueue

func NewEventQueueForStore 

func NewEventQueueForStore(keyFunc cache.KeyFunc, knownObjects cache.KeyListerGetter) *EventQueue

func (*EventQueue) Pop 

func (queue *EventQueue) Pop(process ProcessEventFunc, expectedType interface{}) (interface{}, error)

Process queued changes for an object. The 'process' function is called repeatedly with each available cache.Delta that describes state changes for that object. If the process function returns an error queued changes for that object are dropped but processing continues with the next available object's cache.Deltas. The error is logged with call stack information.
