Overview

The inifile module lets Puppet manage settings stored in INI-style configuration files.

Module Description

Many applications use INI-style configuration files to store their settings. This module supplies two custom resource types to let you manage those settings through Puppet.

Setup

Beginning with inifile

To manage a single setting in an INI file, add the ini_setting type to a class:

ini_setting { "sample setting":
  ensure  => present,
  path    => '/tmp/foo.ini',
  section => 'bar',
  setting => 'baz',
  value   => 'quux',
}

Usage

The inifile module is used to:

  • Support comments starting with either '#' or ';'.
  • Support either whitespace or no whitespace around '='.
  • Add any missing sections to the INI file.

It does not manipulate your file any more than it needs to. In most cases, it doesn't affect the original whitespace, comments, or ordering. See the common usages below for examples.

Manage multiple values in a setting

Use the ini_subsetting type:

ini_subsetting {'sample subsetting':
  ensure            => present,
  section           => '',
  key_val_separator => '=',
  path              => '/etc/default/pe-puppetdb',
  setting           => 'JAVA_ARGS',
  subsetting        => '-Xmx',
  value             => '512m',
}

Results in managing this -Xmx subsetting:

JAVA_ARGS="-Xmx512m -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/var/log/pe-puppetdb/puppetdb-oom.hprof"

Use a non-standard section header

ini_setting { 'default minage':
  ensure         => present,
  path           => '/etc/security/users',
  section        => 'default',
  setting        => 'minage',
  value          => '1',
  section_prefix => '',
  section_suffix => ':',
}

Results in:

default:
   minage = 1

Use a non-standard indent character

To use a non-standard indent character or string for added settings, set the indent_char and the indent_width parameters. The indent_width parameter controls how many indent_char appear in the indent.

ini_setting { 'procedure cache size':
  ensure         => present,
  path           => '/var/lib/ase/config/ASE-16_0/SYBASE.cfg',
  section        => 'SQL Server Administration',
  setting        => 'procedure cache size',
  value          => '15000',
  indent_char    => "\t",
  indent_width   => 2,
}

Results in:

[SQL Server Administration]
        procedure cache size = 15000

Implement child providers

You might want to create child providers that inherit the ini_setting provider for one of the following reasons:

  • To make a custom resource to manage an application that stores its settings in INI files, without recreating the code to manage the files themselves.
  • To purge all unmanaged settings from a managed INI file.

To implement child providers, first specify a custom type. Have it implement a namevar called name and a property called value:

#my_module/lib/puppet/type/glance_api_config.rb
Puppet::Type.newtype(:glance_api_config) do
  ensurable
  newparam(:name, :namevar => true) do
    desc 'Section/setting name to manage from glance-api.conf'
    # namevar should be of the form section/setting
    newvalues(/\S+\/\S+/)
  end
  newproperty(:value) do
    desc 'The value of the setting to define'
    munge do |v|
      v.to_s.strip
    end
  end
end

Your type also needs a provider that uses the ini_setting provider as its parent:

# my_module/lib/puppet/provider/glance_api_config/ini_setting.rb
Puppet::Type.type(:glance_api_config).provide(
  :ini_setting,
  # set ini_setting as the parent provider
  :parent => Puppet::Type.type(:ini_setting).provider(:ruby)
) do
  # implement section as the first part of the namevar
  def section
    resource[:name].split('/', 2).first
  end
  def setting
    # implement setting as the second part of the namevar
    resource[:name].split('/', 2).last
  end
  # hard code the file path (this allows purging)
  def self.file_path
    '/etc/glance/glance-api.conf'
  end
end

Now you can manage the settings in the /etc/glance/glance-api.conf file as individual resources:

glance_api_config { 'HEADER/important_config':
  value => 'secret_value',
}

If you've implemented self.file_path, you can have Puppet purge the file of the all lines that aren't implemented as Puppet resources:

resources { 'glance_api_config':
  purge => true,
}

Manage multiple ini_settings

To manage multiple ini_settings, use the inifile::create_ini_settings function.

$defaults = { 'path' => '/tmp/foo.ini' }
$example = { 'section1' => { 'setting1' => 'value1' } }
inifile::create_ini_settings($example, $defaults)

Results in:

ini_setting { '[section1] setting1':
  ensure  => present,
  section => 'section1',
  setting => 'setting1',
  value   => 'value1',
  path    => '/tmp/foo.ini',
}

To include special parameters, use the following code:

$defaults = { 'path' => '/tmp/foo.ini' }
$example = {
  'section1' => {
    'setting1'  => 'value1',
    'settings2' => {
      'ensure' => 'absent'
    }
  }
}
inifile::create_ini_settings($example, $defaults)

Results in:

ini_setting { '[section1] setting1':
  ensure  => present,
  section => 'section1',
  setting => 'setting1',
  value   => 'value1',
  path    => '/tmp/foo.ini',
}
ini_setting { '[section1] setting2':
  ensure  => absent,
  section => 'section1',
  setting => 'setting2',
  path    => '/tmp/foo.ini',
}

Manage multiple ini_settings with Hiera

For the profile example:

class profile::example (
  Hash $settings,
) {
  $defaults = { 'path' => '/tmp/foo.ini' }
  inifile::create_ini_settings($settings, $defaults)
}

Provide this in your Hiera data:

profile::example::settings:
  section1:
    setting1: value1
    setting2: value2
    setting3:
      ensure: absent

Results in:

ini_setting { '[section1] setting1':
  ensure  => present,
  section => 'section1',
  setting => 'setting1',
  value   => 'value1',
  path    => '/tmp/foo.ini',
}
ini_setting { '[section1] setting2':
  ensure  => present,
  section => 'section1',
  setting => 'setting2',
  value   => 'value2',
  path    => '/tmp/foo.ini',
}
ini_setting { '[section1] setting3':
  ensure  => absent,
  section => 'section1',
  setting => 'setting3',
  path    => '/tmp/foo.ini',
}

create_ini_settings

When using inifile::create_ini_settings it’s worth noting that namespace tags will not be applied to the resource. If you need these namespace tags we advise using the standard ini_setting resource.

Development

We are experimenting with a new tool for running acceptance tests. It's name is puppet_litmus this replaces beaker as the test runner. To run the acceptance tests follow the instructions here.

Puppet Labs modules on the Puppet Forge are open projects, and community contributions are essential for keeping them great. We can't access the huge number of platforms and myriad of hardware, software, and deployment configurations that Puppet is intended to serve.

We want to keep it as easy as possible to contribute changes so that our modules work in your environment. There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things.

For more information, see our module contribution guide.
