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

type Chain

type Chain struct {

func (d *DNS) Size() int

func (*DNS) Update

func (d *DNS) Update() (error, bool)

type EgressDNS

type EgressDNS struct {
	// contains filtered or unexported fields
}

func NewEgressDNS

func NewEgressDNS() *EgressDNS

func (*EgressDNS) Add

func (e *EgressDNS) Delete(policy osapi.EgressNetworkPolicy)

func (*EgressDNS) GetIPs

func (e *EgressDNS) GetIPs(policy osapi.EgressNetworkPolicy, dnsName string) []net.IP

func (*EgressDNS) GetMinQueryTime

func (e *EgressDNS) GetMinQueryTime() (time.Time, ktypes.UID, string, bool)

func (*EgressDNS) GetNetCIDRs

func (e *EgressDNS) GetNetCIDRs(policy osapi.EgressNetworkPolicy, dnsName string) []net.IPNet

func (*EgressDNS) Sync

func (e *EgressDNS) Sync()

func (*EgressDNS) Update

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

type EgressDNSUpdate

type EgressDNSUpdate struct {
	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.

type NetworkInfo

type NetworkInfo struct {
	ClusterNetwork *net.IPNet
	ServiceNetwork *net.IPNet

	// contains filtered or unexported fields
}

func NewProxyPlugin

type ProcessEventFunc

type ProcessEventFunc func(delta cache.Delta) error

Function should process one object delta, which represents a change notification for a single object. Function is passed the delta, which contains the changed object or the deleted final object state. The deleted final object state is extracted from the DeletedFinalStateUnknown passed by DeltaFIFO.
