##Overview

This module allow you to manage your confd templates and resources in Puppet. All configuration options are available and can be defined in Hiera

This module will install, configure and manage your resources and templates.

##Setup

Once you have this module installed you'll need a site module to store your templates and ssl certficates (if you're using them).

It should have the following structure:

site_confd
└── files
    ├── confd-0.5.0
    ├── confd-x.x.x
    ├── confd-latest -> confd-0.5.0
    ├── ssl
    │   ├── ssl.crt
    │   └── ssl.key
    └── templates
        ├── resource1.tmpl
        ├── resource2.tmpl
        └── ...

You'll need to download the confd binary of you choice and ensure it matches confd-$version, the default value for version is latest. This allows you to run multiple versions of confd should you wish, can you symlink the default to confd-latest.

You can also customise the name of site module by setting the confd::sitemodule param.

To setup confd with all defaults you can simply include the class

include confd

This will copy the confd binary and create all required the directory structure and sync your assets from the site module.

###The confd class

####Parameters

These params are available to the confd class:

#####version

Integer: defaults to latest

Description: This sets the confd binary to be installed from the site module

#####installdir

Absolute path: defaults to /usr/local/bin for Debian and /usr/bin for RedHat/Amazon

Description: This set where the confd binary will be stored

#####sitemodule

String: defaults to site_confd

Description: Specifies the name of the site module for templates, ssl certs and binaries

#####confdir

Absolute path: defaults to /etc/confd/

Description: Specifies where all the configuration for confd will live

Other Parameters

All other parameters are directly mapped to the configuration in confd.toml please see the documentation for full details.

###The confd resource define

####Parameters

Please see the confd documentation for the available parameters, they are mapped directly and have validation checks based on the types.

##Examples

###Install confd with etcd backend and define a resource

class { 'confd':
  nodes    => [ 'etcd-1:4001', 'etcd-2:4001' ],
  interval => 10
  prefix   => '/confd'
}

confd::resource { 'nginx_upstream_01':
  dest       => '/etc/nginx/conf.d/upstream_01.conf',
  src        => 'nginx_upstream.tmpl',
  keys       => [ '/nginx/upstream/01' ],
  group      => 'root',
  owner      => 'root',
  mode       => 0644,
  check_cmd  => '/usr/sbin/nginx -t',
  reload_cmd => '/usr/sbin/nginx -s reload'
}

The src value in the resource will be looking for a template in /etc/confd/templates/nginx_upstream.tmpl so this will need to exist in the sites module under files/templates/nginx_upstream.tmpl

###Hiera resource lookup

You can also define your resources in hiera under the variable confd::resources and these will automatically be created when the confd class is instantiated.

####Example JSON hiera:

"confd::resources": { 
  "nginx_upstream_01": {
    "dest": "/etc/nginx/conf.d/upstream_01.conf",
    "src": "nginx_upstream.tmpl",
    "keys": [ 
      "/nginx/upstream/01"
    ],
    "group": "root",
    "owner": "root",
    "mode": "0644",
    "check_cmd": "/usr/sbin/nginx -t",
    "reload_cmd": "/usr/sbin/nginx -s reload"
  },
  "nginx_upstream_02": {
    "dest": "/etc/nginx/conf.d/upstream_02.conf",
    "src": "nginx_upstream.tmpl",
    "keys": [ 
      "/nginx/upstream/02"
    ],
    "group": "root",
    "owner": "root",
    "mode": "0644",
    "check_cmd": "/usr/sbin/nginx -t",
    "reload_cmd": "/usr/sbin/nginx -s reload"
  }
}
