Overview

Package configexport is the registrar's cross-cluster config EXPORT controller (proposal 026 EM1c). Leader-elected (one author per cluster), it watches the GAMMA config (HTTPRoute/GRPCRoute) + MCS ServiceExports and writes the projected config of each EXPORTED route-target Service into the shared registry (registry.ConfigExporter), for peer clusters to import. It uses the SAME common/gammaproject projector the agent uses for local routing, so exported config and local config never drift.

Types

type Controller

type Controller struct {
	client.Client
	// Exporter is the registry's cross-cluster config write capability. Required.
	Exporter registry.ConfigExporter
	// MeshDomain resolves backends to data-plane cluster names.
	MeshDomain string
	// Cluster is this cluster's name (the export origin; used to scope cleanup).
	Cluster string
	Log     *slog.Logger
	// contains filtered or unexported fields
}

Controller projects exported services' GAMMA config and writes it to the registry.

func (*Controller) Reconcile

func (c *Controller) Reconcile(ctx context.Context, _ reconcile.Request) (reconcile.Result, error)

Reconcile (level-based) projects every exported route-target Service's GAMMA config and reconciles it into the registry: SetConfig changed/new projections, UnsetConfig the ones this cluster previously exported but no longer has.

func (*Controller) SetupWithManager

func (c *Controller) SetupWithManager(mgr ctrl.Manager) error

SetupWithManager registers the controller. It watches HTTPRoutes/GRPCRoutes (the config), ServiceExports (which services propagate), and ReferenceGrants (backend resolution); the optional HTTPFilter watch is gated on the CRD being present.
