How to use the @hapi/glue.compose function in @hapi/glue

before(async () => {
        server = await Glue.compose(serverConfig.manifest, options);

        const res = await server.inject({
            url: `/`,
            method: 'get'
        });
        const header = res.headers['set-cookie'];

        // ref: https://github.com/hapijs/crumb/blob/master/test/index.js#L134
        cookie = header[0].match(/crumb=([^\x00-\x20\"\,\;\\\x7F]*)/);
    });

exports.deployment = async (start) => {

    const manifest = Manifest.get('/', process.env);
    const server = await Glue.compose(manifest, { relativeTo: __dirname });

    await server.initialize();

    // $lab:coverage:off$
    if (!start) {
        return server;
    }

    await server.start();

    console.log(`Server started at ${server.info.uri}`);

    return server;

};

exports.start = async function(plugins) {
    ConfigValidation.validate(Config);

    // create a new hapi server
    const server = await Glue.compose(
        internals.buildManifest(plugins),
        {
            relativeTo: internals.pluginsPath
        }
    );

    Hoek.assert(server.settings.app, 'server settings should not be empty');

    // get the server name
    const connection = server.settings.app.name;
    Hoek.assert(connection, 'server requires a name setting');

    // create a new exiting manager for all the hapi servers
    internals.manager = Exiting.createManager(server);
    await internals.manager.start();

const startServer = async function () {
    try {
        const server = await Glue.compose(serverConfig.manifest, options);
        await server.start();
