Access Through Proxy

Having trouble connecting through a corporate proxy to a host. the http module in node by can connect through a proxy by specifying

{
    host: 'proxy.example.com',
    path: 'http://example.elasticsearch.com'
}

however specifying this in the elasticsearch hosts configurations don’t work as expected.

Maybe this code can help someone.

Add an env variable to reach your proxy HTTP_PROXY = http://127.0.0.1:5000/

const elasticsearch = require('elasticsearch');
const proxy = require('proxy-agent');

const client = new elasticsearch.Client({
  host: 'my.host.com',
  createNodeAgent: () => proxy(process.env.HTTP_PROXY)
});

client.search(query);

Au revoir 😚

@clakech Thanks very much, that worked for us too.

I had to code it slightly differently to cater for the PROXY env var being missing - in whichcase a direct connection is made:

'use strict';

const elastic = require('elasticsearch'),
      proxy = require('proxy-agent'),
      config = require('../../config/config.js');

let nodeAgent;

if(process.env.MY_ELASTIC_PROXY) {
  nodeAgent = () => proxy(process.env.MY_ELASTIC_PROXY);
}

const client = new elastic.Client({
  host:               config.elastic.host,
  log:                config.elastic.log,
  suggestCompression: config.elastic.compression,
  apiVersion:         config.elastic.apiVersion,
  createNodeAgent:    nodeAgent
});
