Functions

func CanUseWinKernelProxier 

func CanUseWinKernelProxier(kcompat KernelCompatTester) (bool, error)

CanUseWinKernelProxier returns true if we should use the Kernel Proxier instead of the "classic" userspace Proxier. This is determined by checking the windows kernel version and for the existence of kernel features.

func CleanupLeftovers 

func CleanupLeftovers() (encounteredError bool)

CleanupLeftovers removes all hns rules created by the Proxier It returns true if an error was encountered. Errors are logged.

func Enum 

func Enum(p v1.Protocol) uint16

func Log 

func Log(v interface{}, message string, level klog.Level)

func LogJson 

func LogJson(interfaceName string, v interface{}, message string, level klog.Level)

func NewDualStackProxier 

func NewDualStackProxier(
	syncPeriod time.Duration,
	minSyncPeriod time.Duration,
	masqueradeAll bool,
	masqueradeBit int,
	clusterCIDR string,
	hostname string,
	nodeIP [2]net.IP,
	recorder events.EventRecorder,
	healthzServer healthcheck.ProxierHealthUpdater,
	config config.KubeProxyWinkernelConfiguration,
) (proxy.Provider, error)

func RegisterMetrics 

func RegisterMetrics()

RegisterMetrics registers kube-proxy metrics for Windows modes.

Types

type DualStackCompatTester 

type DualStackCompatTester struct{}

func (DualStackCompatTester) DualStackCompatible 

func (t DualStackCompatTester) DualStackCompatible(networkName string) bool

type HostNetworkService 

type HostNetworkService interface {
	// contains filtered or unexported methods
}

type KernelCompatTester 

type KernelCompatTester interface {
	IsCompatible() error
}

KernelCompatTester tests whether the required kernel capabilities are present to run the windows kernel proxier.

type Proxier 

type Proxier struct {
	// TODO(imroc): implement node handler for winkernel proxier.
	proxyconfig.NoopNodeHandler
	// contains filtered or unexported fields
}

Proxier is an hns based proxy for connections between a localhost:lport and services that provide the actual backends.

func NewProxier 

func NewProxier(
	syncPeriod time.Duration,
	minSyncPeriod time.Duration,
	masqueradeAll bool,
	masqueradeBit int,
	clusterCIDR string,
	hostname string,
	nodeIP net.IP,
	recorder events.EventRecorder,
	healthzServer healthcheck.ProxierHealthUpdater,
	config config.KubeProxyWinkernelConfiguration,
) (*Proxier, error)

NewProxier returns a new Proxier

func (*Proxier) OnEndpointSliceAdd 

func (proxier *Proxier) OnEndpointSliceAdd(endpointSlice *discovery.EndpointSlice)

OnEndpointSliceAdd is called whenever creation of a new endpoint slice object is observed.

func (*Proxier) OnEndpointSliceDelete 

func (proxier *Proxier) OnEndpointSliceDelete(endpointSlice *discovery.EndpointSlice)

OnEndpointSliceDelete is called whenever deletion of an existing endpoint slice object is observed.

func (*Proxier) OnEndpointSliceUpdate 

func (proxier *Proxier) OnEndpointSliceUpdate(_, endpointSlice *discovery.EndpointSlice)

OnEndpointSliceUpdate is called whenever modification of an existing endpoint slice object is observed.

func (*Proxier) OnEndpointSlicesSynced 

func (proxier *Proxier) OnEndpointSlicesSynced()

OnEndpointSlicesSynced is called once all the initial event handlers were called and the state is fully propagated to local cache.

func (*Proxier) OnEndpointsAdd 

func (proxier *Proxier) OnEndpointsAdd(endpoints *v1.Endpoints)

OnEndpointsAdd is called whenever creation of new endpoints object is observed.

func (*Proxier) OnEndpointsDelete 

func (proxier *Proxier) OnEndpointsDelete(endpoints *v1.Endpoints)

OnEndpointsDelete is called whenever deletion of an existing endpoints object is observed.

func (*Proxier) OnEndpointsSynced 

func (proxier *Proxier) OnEndpointsSynced()

OnEndpointsSynced is called once all the initial event handlers were called and the state is fully propagated to local cache.

func (*Proxier) OnEndpointsUpdate 

func (proxier *Proxier) OnEndpointsUpdate(oldEndpoints, endpoints *v1.Endpoints)

OnEndpointsUpdate is called whenever modification of an existing endpoints object is observed.

func (*Proxier) OnServiceAdd 

func (proxier *Proxier) OnServiceAdd(service *v1.Service)

OnServiceAdd is called whenever creation of new service object is observed.

func (*Proxier) OnServiceDelete 

func (proxier *Proxier) OnServiceDelete(service *v1.Service)

OnServiceDelete is called whenever deletion of an existing service object is observed.

func (*Proxier) OnServiceSynced 

func (proxier *Proxier) OnServiceSynced()

OnServiceSynced is called once all the initial event handlers were called and the state is fully propagated to local cache.

func (*Proxier) OnServiceUpdate 

func (proxier *Proxier) OnServiceUpdate(oldService, service *v1.Service)

OnServiceUpdate is called whenever modification of an existing service object is observed.

func (*Proxier) Sync 

func (proxier *Proxier) Sync()

Sync is called to synchronize the proxier state to hns as soon as possible.

func (*Proxier) SyncLoop 

func (proxier *Proxier) SyncLoop()

SyncLoop runs periodic work. This is expected to run as a goroutine or as the main loop of the app. It does not return.

type StackCompatTester 

type StackCompatTester interface {
	DualStackCompatible(networkName string) bool
}

StackCompatTester tests whether the required kernel and network are dualstack capable

type WindowsKernelCompatTester 

type WindowsKernelCompatTester struct{}

func (WindowsKernelCompatTester) IsCompatible
