Overview

This module provides functions and facts that are out of scope for stdlib. Some of them are even intrinsically tied to stdlib.

Setup

 % puppet module install puppet-extlib

Usage

Since puppet/extlib version 3, all functions are provided under the extlib namespace. Non namespaced versions were removed in version 5.

All functions are documented in REFERENCE.md

Facts

All facts in this module are namespaced and begin extlib__. Facter 4 users can also find all facts under a single extlib toplevel structured fact.

extlib__puppet_config (or extlib['puppet_config'] when using facter 4)

A fact to expose puppet.conf settings. These are resolved on the agent, (unlike $settings::<setting_name> which is resolved on the puppet master).

The following sections/settings are included.

{
  main => {
    hostpubkey,
    hostprivkey,
    hostcert,
    localcacert,
    ssldir,
    vardir,
    server,
  },
  master => {
    localcacert,
    ssldir,
  }
}

Limitations

Some functions require puppetlabs-stdlib (>= 4.6.0) and all functions are only compatible with Puppet 4.7 and later.

Development

We highly welcome new contributions to this module, especially those that include documentation, and rspec tests ;) but will happily guide you through the process, so, yes, please submit that pull request!

Reference documentation is generated using puppet-strings. To regenerate it, please run the rake task as follows.

bundle exec rake reference

Functions

extlib::cache_data

Type: Ruby 4.x API

Retrieves data from a cache file, or creates it with supplied data if the file doesn't exist

Useful for having data that's randomly generated once on the master side (e.g. a password), but then stays the same on subsequent runs. Because it's stored on the master on disk, it doesn't work when you use mulitple Puppet masters that don't share their vardir.

Examples

Calling the function

$password = cache_data('mysql', 'mysql_password', 'this_is_my_password')

With a random password

$password = cache_data('mysql', 'mysql_password', random_password())

extlib::cache_data(String[1] $namespace, String[1] $name, Any $initial_data)

Retrieves data from a cache file, or creates it with supplied data if the file doesn't exist

Useful for having data that's randomly generated once on the master side (e.g. a password), but then stays the same on subsequent runs. Because it's stored on the master on disk, it doesn't work when you use mulitple Puppet masters that don't share their vardir.

Returns: Any The cached value when it exists. The initial data when no cache exists

Examples

Calling the function

$password = cache_data('mysql', 'mysql_password', 'this_is_my_password')

With a random password

$password = cache_data('mysql', 'mysql_password', random_password())

extlib::read_url

Type: Ruby 4.x API

Fetch a string from a URL (should only be used with 'small' remote files).

This function should only be used with trusted/internal sources. This is especially important if using it in conjunction with inline_template or inline_epp. The current implementation is also very basic. No thought has gone into timeouts, support for redirects, CA paths etc.

Examples

extlib::read_url(Stdlib::HTTPUrl $url)

Fetch a string from a URL (should only be used with 'small' remote files).

extlib::resources_deep_merge

Type: Ruby 4.x API

Deeply merge a "defaults" hash into a "resources" hash like the ones expected by create_resources().

Internally calls the puppetlabs-stdlib function deep_merge(). In case of duplicate keys the resources hash keys win over the defaults hash keys.

Example

$defaults_hash = {
  'one'   => '1',
  'two'   => '2',
  'three' => '3',
  'four'  => {
    'five'  => '5',
    'six'   => '6',
    'seven' => '7',
  }
}

$numbers_hash = {
  'german' => {
    'one'   => 'eins',
    'three' => 'drei',
    'four'  => {
      'six' => 'sechs',
    },
  },
  'french' => {
    'one' => 'un',
    'two' => 'deux',
    'four' => {
      'five'  => 'cinq',
      'seven' => 'sept',
    },
  }
}

$result_hash = resources_deep_merge($numbers_hash, $defaults_hash)

The $result_hash then looks like this:

$result_hash = {
  'german' => {
    'one'   => 'eins',
    'two'   => '2',
    'three' => 'drei',
    'four'  => {
      'five'  => '5',
      'six'   => 'sechs',
      'seven' => '7',
    }
  },
  'french' => {
    'one'   => 'un',
    'two'   => 'deux',
    'three' => '3',
    'four'  => {
      'five'  => 'cinq',
      'six'   => '6',
      'seven' => 'sept',
    }
  }
}

extlib::resources_deep_merge(Hash $resources, Hash $defaults)

Deeply merge a "defaults" hash into a "resources" hash like the ones expected by create_resources().

Internally calls the puppetlabs-stdlib function deep_merge(). In case of duplicate keys the resources hash keys win over the defaults hash keys.

Example

$defaults_hash = {
  'one'   => '1',
  'two'   => '2',
  'three' => '3',
  'four'  => {
    'five'  => '5',
    'six'   => '6',
    'seven' => '7',
  }
}

$numbers_hash = {
  'german' => {
    'one'   => 'eins',
    'three' => 'drei',
    'four'  => {
      'six' => 'sechs',
    },
  },
  'french' => {
    'one' => 'un',
    'two' => 'deux',
    'four' => {
      'five'  => 'cinq',
      'seven' => 'sept',
    },
  }
}

$result_hash = resources_deep_merge($numbers_hash, $defaults_hash)

The $result_hash then looks like this:

$result_hash = {
  'german' => {
    'one'   => 'eins',
    'two'   => '2',
    'three' => 'drei',
    'four'  => {
      'five'  => '5',
      'six'   => 'sechs',
      'seven' => '7',
    }
