## Getting Started

These instructions will get you a copy of the role for your ansible playbook. Once launched, it will install a [Prometheus MySQL Exporter](https://github.com/prometheus/mysqld_exporter) server in a Debian system.

*Note:* Beginning with the 3.0 version, the default behaviour is the service sending logs to systemd's journal instead to a log file. You can change it modifying the necessary ansible vars (see defaults/main.yml)
### Prerequisities

Ansible >= 2.9.0 version installed.
Inventory destination should be a Debian environment.

For testing purposes, [Molecule](https://molecule.readthedocs.io/) with Docker as driver and [Goss](http://goss.rocks) as verifier

### Installing

Create or add to your roles dependency file (e.g requirements.yml) from GitHub:

```
- src: http://github.com/idealista/prometheus_mysqld_exporter_role.git
scm: git
version: 3.4.0
name: prometheus_mysqld_exporter
```

or using [Ansible Galaxy](https://galaxy.ansible.com/idealista/prometheus_mysqld_exporter_role/) as origin if you prefer:

```
- src: idealista.prometheus_mysqld_exporter_role
```

Install the role with ansible-galaxy command:

```
ansible-galaxy install -p roles -r requirements.yml -f
```

Use in a playbook:

```
- hosts: someserver
roles:
- { role: prometheus_mysqld_exporter }
```

## Usage

Look to the [defaults](defaults/main.yml) properties file to see the possible configuration properties.

## Testing

### Installing dependencies

```sh
$ pipenv sync
$ pipenv run molecule test
```

For more information read the [pipenv docs](https://docs.pipenv.org/).

### Running test

```
$ pipenv run molecule test
```

See molecule/molecule.yml to check possible testing platforms.
