type Conntracker ¶

type Conntracker interface {
	// SetMax adjusts nf_conntrack_max.
	SetMax(max int) error
	// SetTCPEstablishedTimeout adjusts nf_conntrack_tcp_timeout_established.
	SetTCPEstablishedTimeout(seconds int) error
	// SetTCPCloseWaitTimeout nf_conntrack_tcp_timeout_close_wait.
	SetTCPCloseWaitTimeout(seconds int) error
}

Conntracker is an interface to the global sysctl. Descriptions of the various sysctl fields can be found here:

	ConfigFile string
	// CleanupAndExit, when true, makes the proxy server clean up iptables rules, then exit.
	CleanupAndExit bool
	// contains filtered or unexported fields
}

Options contains everything necessary to create and run a proxy server.

type ProxyServer ¶

type ProxyServer struct {
	Client                 clientset.Interface
	EventClient            v1core.EventsGetter
	IptInterface           utiliptables.Interface
	Proxier                proxy.ProxyProvider
	Broadcaster            record.EventBroadcaster
	Recorder               record.EventRecorder
	ConntrackConfiguration componentconfig.KubeProxyConntrackConfiguration
	Conntracker            Conntracker // if nil, ignored
	ProxyMode              string
	NodeRef                *clientv1.ObjectReference
	CleanupAndExit         bool
	HealthzBindAddress     string
	OOMScoreAdj            *int32
	ResourceContainer      string
	ConfigSyncPeriod       time.Duration
	ServiceEventHandler    proxyconfig.ServiceHandler
	// TODO: Migrate all handlers to ServiceHandler types and
	// get rid of this one.
	ServiceHandler        proxyconfig.ServiceConfigHandler
	EndpointsEventHandler proxyconfig.EndpointsHandler
}
