Hi guys, i'm hitting this over & over again.

 Elasticsearch ERROR: 2016-01-07T21:20:52Z
  Error: Request error, retrying -- connect ECONNREFUSED 127.0.0.1:9200

The situation is like this. I have a nodejs app running inside a docker container.
Inside this app, I've create the client like this

var client = new elasticsearch.Client({
        connectionClass: CustomESHTTPConnector,
        host: process.env.ELASTICSEARCH_HOST,
        deadTimeout: 100000,
        maxRetries: 6
    });

Where ELASTICSEARCH_HOST is the address of another VM inside the same network => 10.0.0.5 running ES, of course

If I curl 10.0.0.5:9200 inside the container, and inside the VM hosting that container, I get

{
  "name" : "app-node",
  "cluster_name" : "app-cluster",
  "version" : {
    "number" : "2.1.1",
    "build_hash" : "40e2c53a6b6c2972b3d13846e450e66f4375bd71",
    "build_timestamp" : "2015-12-15T13:05:55Z",
    "build_snapshot" : false,
    "lucene_version" : "5.3.1"
  },
  "tagline" : "You Know, for Search"
}

The app shoud reach the elasticsearch server. Any ideas why im getting this? Thanks in advance

Closing this.

The error was the process.env.ELASTICSEARCH_HOST not being set at the runtime for another reason. Thaks for your help @iquirino & @spalger !

Is this happening on the first request or only after some time?

spalger picture spalger on 8 Jan 2016

Yes, on the first request. When trying to create the index. On the elasticsearch logs I'cant see any connection. It seems like its not reaching the server at all

matiasdecarli picture matiasdecarli on 8 Jan 2016

Maybe elasticsearch isn't listening on 127.0.0.1? ECONNREFUSED is from the network stack, well outside the realm of the client unfortunately

spalger picture spalger on 8 Jan 2016

Right, I'm using the config network.host: 0.0.0.0 on ES (otherwise I can't reach ES from the outside of the VM).

Can this be the problem?

matiasdecarli picture matiasdecarli on 8 Jan 2016

Change network.host: 0.0.0.0 to network.host: "localhost"

Are you using NAT or Bridge?
If using NAT, dont forget to explicitly specify port redirection.

VMWare, Oracle VirtualBox ??

Thank you!

@iquirino I did that, but the problem is that curl 10.0.0.5:9200 from the outside of the VM gives me curl: (7) Failed to connect to 10.0.0.5 port 9200: Connection refused

Im using Azure

UPDATE: Im still having the exact same issue even when running network.host: "localhost"

@Cuong12 Please put your log output inside well-indented code-blocks so that's more readable, thank you.

@Cuong12 - Locate the 'elasticsearch.js' file on your system, then change the variable this.host = 'localhost' to this.host = '0.0.0.0'
