Types

type TunnelController

type TunnelController struct {
	client.Client
	record.EventRecorder
	tunnel.Driver
	utils.NetLink
	utils.IPTablesHandler
	DefaultIface string
	// contains filtered or unexported fields
}

TunnelController reconciles a TunnelEndpoint object

func NewTunnelController

func NewTunnelController(mgr ctrl.Manager, wgc wireguard.Client, nl wireguard.Netlinker) (*TunnelController, error)

Instantiates and initializes the tunnel controller

func (*TunnelController) EnsureIPTablesRulesPerCluster

func (tc *TunnelController) EnsureIPTablesRulesPerCluster(tep *netv1alpha1.TunnelEndpoint) error

func (*TunnelController) Reconcile

func (tc *TunnelController) Reconcile(req ctrl.Request) (ctrl.Result, error)

func (*TunnelController) RemoveAllTunnels

func (tc *TunnelController) RemoveAllTunnels()

used to remove all the tunnel interfaces when the controller is closed it does not return an error, but just logs them, cause we can not recover from them at exit time

func (*TunnelController) SetUpIPTablesHandler

func (tc *TunnelController) SetUpIPTablesHandler() error

func (*TunnelController) SetUpRouteManager

func (tc *TunnelController) SetUpRouteManager(recorder record.EventRecorder)

func (*TunnelController) SetUpTunnelDrivers

func (tc *TunnelController) SetUpTunnelDrivers() error

for each registered tunnel implementation it creates and initializes the driver

func (*TunnelController) SetupSignalHandlerForTunnelOperator

func (tc *TunnelController) SetupSignalHandlerForTunnelOperator() (stopCh <-chan struct{})

SetupSignalHandlerForRouteOperator registers for SIGTERM, SIGINT, SIGKILL. A stop channel is returned which is closed on one of these signals.

func (*TunnelController) SetupWithManager

func (tc *TunnelController) SetupWithManager(mgr ctrl.Manager) error

func (*TunnelController) StartPodWatcher

func (tc *TunnelController) StartPodWatcher()

func (*TunnelController) StartServiceWatcher

func (tc *TunnelController) StartServiceWatcher()

func (*TunnelController) WatchConfiguration

func (tc *TunnelController) WatchConfiguration(config *rest.Config, gv *schema.GroupVersion)
