## Overview

This module manages InfluxDB installation.

[![Build Status](https://travis-ci.org/n1tr0g/golja-influxdb.png)](https://travis-ci.org/n1tr0g/golja-influxdb) [![Puppet Forge](http://img.shields.io/puppetforge/v/golja/influxdb.svg)](https://forge.puppetlabs.com/golja/influxdb)

## Module Description

The InfluxDB module manages both the installation and configuration of InfluxDB.
I am planning to extend it to allow management of InfluxDB resources,
such as databases, users, and privileges.

## Deprecation Warning

Notes for version 5.0.0+:

This module was a refactor of the 4.x version to handle influxdb >= 1.x.
Due to the changes in influxdb 1.x, this module should now support
future change more easily due to thew way the configuration files are
now managed.

Highlights
==========

* The module layout out has changed significantly from previous versions.
* A new fact was added `influxdb_version`.
* The influxdb.conf.erb file was refactored.
* Added and fixed a lot of rspec puppet tests.
* Fixed all the beaker tests, they work now.
* This module now supports influxdb >= 1.x < 2.x
* Major change to the original class parameters now hashes vs individual items.

Notes for version 4.0.0+:

influxdb 1.0.0 contains [breaking changes](https://github.com/influxdata/influxdb/blob/master/CHANGELOG.md#v100-2016-09-08)
which require changing the `data_logging_enabled` config attribute to `trace_logging_enabled`.
The other configuration changes are managed by the `influxdb.conf.erb` template already.

Notes for versions older than 3.1.1:

This release is a major refactoring of the module which means that the API
changed in backwards incompatible ways. If your project depends on the old API
and you need to use influxdb prior to 0.10.X, please pin your module
dependencies to 0.1.2 (0.8.X) or 2.2.2 (0.9.X) version to ensure your environments
don't break.

*NOTE*: Until influxdb 1.0.0 is releases the API of this module may change,
however I will try my best to avoid it.

## Installation

`puppet module install golja/influxdb`

## Setup

### What InfluxDB affects

*   InfluxDB packages
*   InfluxDB configuration files
*   InfluxDB service

### Beginning with InfluxDB

If you just want a server installed with the default options you can
run include `'::influxdb'`.

## Usage

All interaction for the server is done via `influxdb::server`.

```puppet
class {'influxdb':}
```

```puppet

# These are defaults, but demonstrates how you can change sections of data
$global_config => {
  'bind-address'       => ':8088',
  'reporting-disabled' => false,
}

class {'influxdb':

  manage_service => true,
  version        => '1.2.0',
}
```

## Limitations

This module has been tested on:

*   Ubuntu 12.04
*   Ubuntu 14.04
*   CentOS 6/7

## Development

In order to better facilitate beaker testing, the Gemfile was modified to
support environment variables.  You must set this enviroment variable
before running `bundle exec *`.  The Gemfile will automatically set this
for you but you can also override it.
```
export BEAKER_VERSION=3.10.0 # assumes ruby >= 2.2.5
```

Please see CONTRIBUTING.md

### Todo

*   Add native types for managing users and databases
*   Add more rspec tests
*   Add beaker/rspec tests
