Functions

func ForgeFirewallTargetLabels

func ForgeFirewallTargetLabels() map[string]string

ForgeFirewallTargetLabels returns the labels used by the firewallconfiguration controller to reconcile only resources related to network fabric.

func ForgeFirewallTargetLabelsSingleNode

func ForgeFirewallTargetLabelsSingleNode(nodeName string) map[string]string

ForgeFirewallTargetLabelsSingleNode returns the labels used by the firewallconfiguration controller to reconcile only resources related to network fabric on a specific node.

func ForgeRouteTargetLabels

func ForgeRouteTargetLabels() map[string]string

ForgeRouteTargetLabels returns the labels used by the routecontroller to reconcile only resources related to network fabric.

func InitFlags

func InitFlags(flagset *pflag.FlagSet, opts *Options)

InitFlags initializes the flags for the wireguard tunnel.

func MarkFlagsRequired

func MarkFlagsRequired(cmd *cobra.Command) error

MarkFlagsRequired marks the flags as required.

Types

type FlagName

type FlagName string

FlagName is the type for the name of the flags.

const (
	// FlagNodeNameName is the name of the node where the pod is scheduled.
	FlagNodeNameName FlagName = "nodename"

	// FlagNameMetricsAddress is the address for the metrics endpoint.
	FlagNameMetricsAddress FlagName = "metrics-address"
	// FlagNameProbeAddr is the address for the health probe endpoint.
	FlagNameProbeAddr FlagName = "health-probe-bind-address"

	// FlagEnableARP is the flag to enable ARP.
	FlagEnableARP FlagName = "enable-arp"
)

func (FlagName) String

func (fn FlagName) String() string

type InternalFabricReconciler

type InternalFabricReconciler struct {
	client.Client
	Scheme         *runtime.Scheme
	EventsRecorder record.EventRecorder
	Options        *Options
}

InternalFabricReconciler manage internalfabric.

func NewInternalFabricReconciler

func NewInternalFabricReconciler(cl client.Client, s *runtime.Scheme,
	er record.EventRecorder, opts *Options) (*InternalFabricReconciler, error)

NewInternalFabricReconciler returns a new InternalFabricReconciler.

func (*InternalFabricReconciler) Reconcile

func (r *InternalFabricReconciler) Reconcile(ctx context.Context, req ctrl.Request) (ctrl.Result, error)

Reconcile manage InternalFabrics.

func (*InternalFabricReconciler) SetupWithManager

func (r *InternalFabricReconciler) SetupWithManager(mgr ctrl.Manager) error

SetupWithManager register the InternalFabricReconciler to the manager.

type Options

type Options struct {
	NodeName string
	PodName  string

	MetricsAddress string
	ProbeAddr      string

	EnableARP bool
}

Options contains the options for the wireguard interface.

func NewOptions

func NewOptions() *Options

NewOptions returns a new Options struct.
