Connection handler for Amazon ES

Makes elasticsearch-js compatible with Amazon ES. It uses the aws-sdk to make signed requests to an Amazon ES endpoint.

Installation

# Install the connector, elasticsearch client and aws-sdk
npm install --save http-aws-es aws-sdk elasticsearch

Usage

// create an elasticsearch client for your Amazon ES
let es = require('elasticsearch').Client({
  hosts: [ 'https://amazon-es-host.us-east-1.es.amazonaws.com' ],
  connectionClass: require('http-aws-es')
});

Region + Credentials

The connector uses aws-sdk's default behaviour to obtain region + credentials from your environment. If you would like to set these manually, you can set them on aws-sdk:

let AWS = require('aws-sdk');
AWS.config.update({
  credentials: new AWS.Credentials(accessKeyId, secretAccessKey),
  region: 'us-east-1'
});

Options

let options = {
  hosts: [], // array of amazon es hosts (required)
  connectionClass: require('http-aws-es'), // use this connector (required)
  awsConfig: new AWS.Config({ region }), // set an aws config e.g. for multiple clients to different regions
  httpOptions: {} // set httpOptions on aws-sdk's request. default to aws-sdk's config.httpOptions
};
let es = require('elasticsearch').Client(options);

Test

npm test
# test against a real endpoint
AWS_PROFILE=your-profile npm run integration-test -- --endpoint https://amazon-es-host.us-east-1.es.amazonaws.com --region us-east-1
