I sorta got this working. This expects build to be at ./src/build, and ./src to be the imply-pivot git submodule. It works as nodejs ./app.sh, but for some reason not yet via service-runner. Still working on it.

pivot-app.js

"use strict";
var debugModule = require('debug');
var http = require('http');

function createPivotServer(config) {
    var debug = debugModule('pivot:www');
    config = config || {};

    // HACK!  build/server/config.js uses process.argv directly, so we can't
    // do much about that.
    process.argv = process.argv.slice(0,2);
    if (config.pivot_config_file) {
        process.argv = process.argv.concat([
            '--config',
            config.pivot_config_file
        ]);
    }
    if (config.druid_host) {
        process.argv = process.argv.concat([
            '--druid',
            config.druid_host
        ]);
    }
    if (config.port) {
        process.argv = process.argv.concat([
            '--port',
            config.port
        ]);
    }
    console.log('config', config);
    console.log('argv', process.argv);


    // require config, this will examine process.argv
    var pivotConfig = require('./src/build/server/config');
    console.log(pivotConfig);

    var app = require('./src/build/server/app');
    var server = http.createServer(app);
    server.on('error', function (error) {
        if (error.syscall !== 'listen') {
            throw error;
        }
        switch (error.code) {
            case 'EACCES':
                console.error("Port " + config_1.SERVER_SETTINGS.getPort() + " requires elevated privileges");
                process.exit(1);
                break;
            case 'EADDRINUSE':
                console.error("Port " + config_1.SERVER_SETTINGS.getPort() + " is already in use");
                process.exit(1);
                break;
            default:
                throw error;
        }
    });
    server.on('listening', function () {
        var address = server.address();
        console.log("Pivot is listening on address " + address.address + " port " + address.port);
        debug("Pivot is listening on address " + address.address + " port " + address.port);
    });
    app.set('port', config_1.SERVER_SETTINGS.getPort());
    server.listen(config_1.SERVER_SETTINGS.getPort(), config_1.SERVER_SETTINGS.getServerHost());

    return server;
}

// If this file is being run directly, just create the server with
// defaults and start listening.
if (require.main === module) {
    createPivotServer({
        druid_host: 'localhost:8082'
    });
}

module.exports = function(options) {
    // Pass in service config object from service runner config.yal
    return createPivotServer(options.config);
}
