Hi, I'm using [https://github.com/elastic/ansible-elasticsearch](https://github.com/elastic/ansible-elasticsearch) and cannot find the variables to set the listen address of the elasticsearch endpoints. By default, they are set to listen on 'localhost' which is a problem since I cannot create a cluster since the nodes don't communicate with each others.

Thanks a lot

Looking briefly, I don't see

```
network.host: "0"

```

With any value in the elasticserach.yml.j2 so it's taking a default. If you add the line above to the template, it should listen on "all interfaces". If you need only specific, you will have to create a variable or possibly "ansible\_default\_ipv4". Try ansible -m setup to see if a correct variable exists.
