Functions

func DeletionHandlingMetaNamespaceKeyFunc added in v1.4.0

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

func NewMultiTenantPlugin added in v1.5.0

func NewMultiTenantPlugin() osdnPolicy

func NewNetworkPolicyPlugin added in v1.5.0

func NewNetworkPolicyPlugin() osdnPolicy

func NewSingleTenantPlugin added in v1.5.0

func NewSingleTenantPlugin() osdnPolicy

func RunEventQueue added in v1.4.0

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 RunNamespacedPodEventQueue added in v1.5.0

func RunNamespacedPodEventQueue(client kcache.Getter, namespace string, closeChan chan struct{}, process ProcessEventFunc)

func StartMaster

func StartMaster(networkConfig osconfigapi.MasterNetworkConfig, osClient *osclient.Client, kClient *kclientset.Clientset) error

Types

type EventQueue added in v1.4.0

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 added in v1.4.0

func NewEventQueue(keyFunc cache.KeyFunc) *EventQueue

func NewEventQueueForStore added in v1.4.0

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

func (*EventQueue) Pop added in v1.4.0

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.
