Overview

The openstack_extras module is a part of OpenStack, an effort by the Openstack infrastructure team to provide continuous integration testing and code review for Openstack and Openstack community projects as part of the core software. The module itself is used to add useful utilities for composing and deploying OpenStack with the Openstack puppet modules.

Module Description

The openstack_extras module is intended to provide useful utilities to help with OpenStack deployments, including composition classes, HA utilities, monitoring functionality, and so on.

This module combines other modules in order to build and leverage an entire OpenStack software stack. This module replaces functionality from the deprecated stackforge/puppet-openstack module.

Setup

Installing openstack_extras

puppet module install openstack/openstack_extras

Beginning with openstack_extras

Instructions for beginning with openstack_extras will be added later.

Implementation

openstack_extras

openstack_extras is a combination of Puppet manifest and ruby code to delivery configuration and extra functionality through types and providers.

HA configuration for Openstack services

This module allows to configure Openstack services in HA. Please refer to the ha-guide for details. If you have a Corosync with Pacemaker cluster with several nodes joined, you may want to use an HA service provider which allows you to create the pacemaker resources for Openstack services and run them in HA mode. The example HA service configuration for keystone service:

openstack_extras::pacemaker::service { 'openstack-keystone' :
    ensure             => present,
    metadata           => {},
    ms_metadata        => {},
    operations         => {},
    parameters         => {},
    primitive_class    => 'systemd',
    primitive_provider => false,
    primitive_type     => 'openstack-keystone',
    use_handler        => false,
    clone              => true,
    require            => Package['openstack-keystone']
}

This example will create a pacemaker clone resource named p_openstack-keystone-clone and will start it with the help of systemd.

And this example will create a resource p_cinder-api-clone for Cinder API service with the given OCF script template from some cluster module:

  $metadata = {
    'resource-stickiness' => '1'
  }
  $operations = {
    'monitor'  => {
      'interval' => '20',
      'timeout'  => '30',
    },
    'start'    => {
      'timeout' => '60',
    },
    'stop'     => {
      'timeout' => '60',
    },
  }
  $ms_metadata = {
    'interleave' => true,
  }

  openstack_extras::pacemaker::service { 'cinder-api' :
    primitive_type      => 'cinder-api',
    metadata            => $metadata,
    ms_metadata         => $ms_metadata,
    operations          => $operations,
    clone               => true,
    ocf_script_template => 'cluster/cinder_api.ocf.erb',
  }
