Problem

How can a nodejs process running inside a docker container, get that container's id?

Solution

the hostname seems to be the short container id in Docker v1.12

It works and this idea was found in this SO post.

var kue = require('kue')

var queue = kue.createQueue({
  redis: process.env.REDIS_URL
});

var JOB_NAME = 'crawl';

queue.process(JOB_NAME, function(job, ctx, done){
  console.log((new Date()).toLocaleString(), 'inside queue.process("'+JOB_NAME+'") for job id:', job.id);

  doSomething(job.data, ctx, done);
  //exit(); // Scenario C: don't like it because shutdown can happen before the job finishes,

1. Install a 3rd party utility to help with wrapping the socket library:

bower install angular-socket-io`

1. Update index.html to provide a websocket implementation like socket.io and the wrapper utility:

<script src="//cdn.socket.io/socket.io-1.1.0.js"></script>
<script src="bower_components/angular-socket-io/socket.min.js"></script>

var express = require('express'),
    app = express(),
    server = require('http').Server(app),
    io = require('socket.io')(server),
    bodyParser = require('body-parser');

// After scaling up, multiple servers can only work with sockets connected to them.
// The socket.io-redis package can solve this by making redis the datastore instead of memory.
