Overview

The heat module is part of OpenStack, an effort by the OpenStack infrastructure team to provice continuous integration testing and code review for OpenStack and OpenStack community projects as part of the core software. The module itself is used to flexibly configure and manage the orchestration service for OpenStack.

Module Description

The heat module is an attempt to make Puppet capable of managing the entirety of heat.

Setup

What the heat module affects

• Heat, the orchestration service for OpenStack

Installing heat

puppet module install openstack/heat

Beginning with heat

To utilize the heat module's functionality you will need to declare multiple resources. The following is a modified excerpt from the openstack module. This is not an exhaustive list of all the components needed. We recommend that you consult and understand the openstack module and the core openstack documentation to assist you in understanding the available deployment options.

# enable heat resources
class { '::heat':
  rabbit_userid       => 'heat',
  rabbit_password     => 'an_even_bigger_secret',
  rabbit_host         => '127.0.0.1',
  database_connection => 'mysql://heat:a_big_secret@127.0.0.1/heat?charset=utf8',
  identity_uri        => 'http://127.0.0.1:35357/',
  keystone_password   => 'a_big_secret',
}

class { '::heat::api': }

class { '::heat::engine':
  auth_encryption_key => '1234567890AZERTYUIOPMLKJHGFDSQ12',
}

class { '::heat::api_cloudwatch': }

class { '::heat::api_cfn': }

Implementation

puppet-heat

heat is a combination of Puppet manifests and Ruby code to deliver configuration and extra functionality through types and providers.

Types

heat_config

The heat_config provider is a children of the ini_setting provider. It allows one to write an entry in the /etc/heat/heat.conf file.

heat_config { 'DEFAULT/enable_stack_adopt' :
  value => True,
}

This will write enable_stack_adopt=True in the [DEFAULT] section.

name

Section/setting name to manage from heat.conf

value

The value of the setting to be defined.

secret

Whether to hide the value from Puppet logs. Defaults to false.

ensure_absent_val

If value is equal to ensure_absent_val then the resource will behave as if ensure => absent was specified. Defaults to <SERVICE DEFAULT>

Limitations

None

Beaker-Rspec

This module has beaker-rspec tests

To run:

bundle install
bundle exec rspec spec/acceptance
