Sample usage of the Elasticsearch Node.js client with ECK

This is a temporary/test repository which might be deleted at any time.

Prerequisites

• A running ECK instance.
• An Elasticsearch cluster deployed with ECK using the sample manifest.

If the cluster is not named elasticsearch-sample or does not live in the default namespace, update the service URL in the sample and the deployment manifest accordingly.

Running the example

• Deploy the sample Pod using the deployment manifest:

kubectl apply -f https://raw.githubusercontent.com/barkbay/eck-elasticsearch-js/master/deployment.yaml

• Run a shell inside the Pod

kubectl exec -ti $(kubectl get pods --selector=app=node --output=jsonpath={.items..metadata.name}) /bin/bash

• Run the sample

root@node-deployment-5dbb6744c6-ngsnk:/usr/src/app# nodejs es.js

If everything is fine you should see something along those lines:

[ { _index: 'game-of-thrones',
    _type: '_doc',
    _id: 'EofsJXUB6sJu3ltUJkuA',
    _score: 0.90487003,
    _source: { character: 'Ned Stark', quote: 'Winter is coming.' } },
  { _index: 'game-of-thrones',
...
  { _index: 'game-of-thrones',
    _type: '_doc',
    _id: 'fETsJXUBDDKFUvQOmb46',
    _score: 0.90487003,
    _source: { character: 'Ned Stark', quote: 'Winter is coming.' } } ]

Note that the client is configured to use client autodiscovery (sniffOnStart: true) by default.
