Overview

The horizon module is a part of Stackforge, an effort by the Openstack infrastructure team to provide continuous integration testing and code review for Openstack and Openstack community projects not part of the core software. The module its self is used to flexibly configure and manage the dashboard service for Openstack.

Module Description

The horizon module is a thorough attempt to make Puppet capable of managing the entirety of horizon. Horizon is a fairly classic django application, which results in a fairly simply Puppet module.

This module is tested in combination with other modules needed to build and leverage an entire Openstack software stack. These modules can be found, all pulled together in the openstack module.

Setup

What the horizon module affects

• horizon, the dashboard service for Openstack.

Installing horizon

example% puppet module install puppetlabs/horizon

Beginning with horizon

To utilize the horizon module's functionality you will need to declare multiple resources but you'll find that doing so is much less complicated than the other OpenStack component modules. The following is a modified excerpt from the openstack module. We recommend you consult and understand the openstack module and the core openstack documentation.

Define a horizon dashboard

class { 'memcached':
  listen_ip => '127.0.0.1',
  tcp_port  => '11211',
  udp_port  => '11211',
}

class { '::horizon':
  cache_server_ip       => '127.0.0.1',
  cache_server_port     => '11211',
  secret_key            => '12345',
  swift                 => false,
  django_debug          => 'True',
  api_result_limit      => '2000',
}

Implementation

horizon

Horizon is a simple module using the combination of a package, template, and the file_line type. Most all the configuration lives inside the included local_settings template and the file_line type is for selectively inserting needed lines into configuration files that aren't explicitly managed by the horizon module.

Limitations

• Only supports Apache using mod_wsgi.

Development
