# ansible-elasticsearch
|
|
|
|
Ansible playbook / roles / tasks for Elasticsearch. Currently it will work on Debian and RedHat based linux systems.
|
|
|
|
## Usage
|
|
|
|
Create your ansible playbook with your own tasks, and include the role elasticsearch.
|
|
You will have to have this repository accessible within the context of playbook, e.g.
|
|
|
|
e.g.
|
|
|
|
```
|
|
cd /my/repos/
|
|
git clone git@github.com:elastic/ansible-elasticsearch.git
|
|
cd /my/ansible/playbook
|
|
mkdir -p roles
|
|
ln -s /my/repos/ansible-elasticsearch ./roles/elasticsearch
|
|
```
|
|
|
|
Then create your playbook yaml adding the role elasticsearch and overriding any variables you wish. It can be as simple as this to take all the defaults:
|
|
|
|
|
|
```
|
|
---
|
|
hosts: my_host
|
|
roles:
|
|
- elasticsearch
|
|
tasks:
|
|
- .... your tasks ...
|
|
```
|
|
|
|
or more complex..
|
|
|
|
|
|
```
|
|
---
|
|
hosts: my_host
|
|
roles:
|
|
- elasticsearch
|
|
vars:
|
|
java_packages:
|
|
- "oracle-java7-installer"
|
|
es_major_version: 1.4
|
|
es_version: 1.4.4
|
|
es_start_service: false
|
|
es_plugins_reinstall: false
|
|
es_plugins:
|
|
- plugin: elasticsearch-cloud-aws
|
|
version: 2.5.0
|
|
- plugin: marvel
|
|
version: latest
|
|
- plugin: license
|
|
version: latest
|
|
- plugin: shield
|
|
version: latest
|
|
- plugin: elasticsearch-support-diagnostics
|
|
version: latest
|
|
tasks:
|
|
- .... your tasks ...
|
|
```
|
|
|
|
Make sure your hosts are defined in your ```hosts``` file with the appropriate ```ansible_ssh_host```, ```ansible_ssh_user``` and ```ansible_ssh_private_key_file``` values.
|
|
|
|
Then run it:
|
|
|
|
```
|
|
ansible-playbook -i hosts ./your-playbook.yml
|
|
```
|
|
|
|
## Configuration
|
|
You can add the role without any customisation and it will by default install Java and Elasticsearch, without any plugins.
