The latest release of puppet-corosync does not yet support pcs 0.10.0, which is now available in CentOS 8/9 or Ubuntu Focal/Jammy. The unreleased change to adapt to pcs 0.10.0[1] made some breaking interface change and our current implementation has not yet fully adapt to it. Because we haven't see any bug report or request to resolve this situation, we can assume this implementation is not really used. Furthermore we don't really have to use pacemaker for most of OpenStack services, and we can use native resource agents such as systemd resource agent instead of injecting own scripts. Let's deprecate it so that we can remove it in a future release. Change-Id: If90e21e41da40171a766c4740ef93d9c05ecd1c7

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',
}
Limitations
- Limitations will be added as they are discovered.
