hosts: localhost
roles:

The above installs Elasticsearch 7.1.1 in a single node 'node1' on the hosts 'localhost'.
**Note**:
Elasticsearch default version is described in [`es_version`](defaults/main.yml#L2). You can override this variable in your playbook to install another version.
While we are testing this role only with one 7.x and one 6.x version (respectively [7.1.1](defaults/main.yml#L2) and [6.8.0](.kitchen.yml#L22) at the time of writing), this role should work with others version also in most cases.
This role also uses [Ansible tags](http://docs.ansible.com/ansible/playbooks_tags.html). Run your playbook with the `--list-tasks` flag for more information.
