		cancel()
	}()

	r := http.NewServeMux()
	r.HandleFunc("/status", func(writer http.ResponseWriter, request *http.Request) {

	})

	server := &http.Server{
		Addr:    ":8888",
		Handler: r}

	group, groupCtx := errgroup.WithContext(ctx)
    // groupCtx will expire when ctx expires or one of the jobs returns an error
	group.Go(libHTTP.MakeServerRunner(
		groupCtx,
		log.Logger.With().Str("http_server", "internal API").Logger(),
		server))
	group.Go(func() error {

		return nil
	})

	if err := group.Wait(); err != nil {
		log.Error().Err(err).Msg("one of job has been failed")
	}
