node-ansible have any default time out process.

[Git-Rajkumar]

I am working on to develop Node+ ansible Module, I need to build mysql docker image via ansible script. while i building image request calling multiple time, if request get second time browser goes to connection was reset.

Note: If second time request build image perfectly. First request only issue, at same time browser goes connection was reset.

What i did:

mysql.js:

  var express = require('express');
  var path = require('path');
  var favicon = require('serve-favicon');
  var logger = require('morgan');
  var bodyParser = require('body-parser');
  var app = express();
  var Ansible = require('node-ansible');
  var yaml = require('node-yaml');
  var timeout = require('infinite-timeout');
  // view engine setup
  app.set('views', path.join(__dirname, 'views'));
  app.set('view engine', 'ejs');
  app.use(bodyParser.json());
  app.use(bodyParser.urlencoded({extended: false}));
  app.use(express.static(path.join(__dirname, 'public')));

  //app.use('/', index.jade);
  app.get('/', function (req, res) {
      tmp = "";

      console.log(req.url);

      res.render('index', {title: ' Mysql Setup'})
  });

  var tmp = "";
  var postcount;
  app.post('/setup', function (req, res) {

      postcount = Object.keys(req.body).length
      console.log(postcount);

      console.log(req.url);

      for (var key in req.body) {

          console.log(req.body[key]);

          if (req.body[key] == "mysql") {


              console.log("within mysql");

              var playbook = new Ansible.Playbook().playbook("mysql");

              playbook.on('stdout', function (data) {
                  console.log(data.toString());
              });
              playbook.on('stderr', function (data) {
                  console.log(data.toString());
              });

              var command = playbook.inventory('inventories/Mysql/hosts').verbose('v');

              var promise = command.exec();
              
              promise.then(function (successResult) {
                  console.log("within mysql sucess");
                  tmp += "Build Mysql Image  Process";
                  tmp += successResult.output;
                  res.render('mysql_build_result', {data: tmp, title: 'Mysql Image Build Result'});

              }, function (error) {
                  tmp += error;
                  console.log("within mysql error");
                  res.render('mysql_build_result', {data: tmp, title: 'Mysql Image Build Result Error'});
              });

              return;
          }else
          {
              console.log("No Request are matched");
          }

      }
  });

  var server = app.listen(3030, function () {

      var host = server.address().address
      var port = server.address().port

      console.log("Example app listening at http://%s:%s", host, port);
  });

Ansible Script:

mysql.yml

    within mysql sucess

Suggest Me What Wrong in my code. Why command.exec(); function to recall new request and build new docker image.

Is there any default time out for first request, if there, how to reset this.

Note: My ansible script to take minimun 20 min to execute the process.
