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.

// 1) Lets start with the simplest query that you can run in
//    the head plugin for ElasticSearch located at the url:
//    http://localhost:9200/_plugin/head/
{
  "query": {
    "match_all": {}

}

// 2) Before jumping into forming queries with the ES Query DSL

Pitfalls

The REST adapter for strong-remoting sets up its own error handler! So you cannot accomplish this for REST API related calls by replacing:

1. app.use(loopback.errorHandler()); in server/server.js
2. or, loopback#errorHandler in middleware.json

So don't waste your time there.
