Functions

func NewBaseGatewayController

func NewBaseGatewayController(ctx context.Context, cfg GatewayConfig) error

func Start

func Start(ctx context.Context, cfg StartConfig) error

Start runs the controllers responsible for processing the K8s Gateway API objects It is intended to be run in a goroutine as the function will block until the supplied context is cancelled
