In order to be able to take an action after all the packages of the module have been installed/updated or all the services have been started/restarted, we set a 'nova-package' and 'nova-service' tag for each package and service of this module. At the moment, there is a generic openstack tag that is not specific enough if one wants to take action upon a single module change. Use case : If an action needs to be taken after all the packages have been installed or updated : Package <| tag == 'nova-package' |> -> X Change-Id: I6a28ed68ba3b0cbdd14cc224e2cf0c253786064a

Overview
The nova 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 its self is used to flexibly configure and manage the compute service for Openstack.
Module Description
The nova module is a thorough attempt to make Puppet capable of managing the entirety of nova. This includes manifests to provision such things as keystone endpoints, RPC configurations specific to nova, and database connections. Types are shipped as part of the nova module to assist in manipulation of configuration files.
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 nova module affects:
- nova, the compute service for Openstack.
Installing nova
example% puppet module install openstack/nova
Beginning with nova
To utilize the nova 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 you consult and understand the openstack module and the core openstack documentation.
class { 'nova':
database_connection => 'mysql://nova:a_big_secret@127.0.0.1/nova?charset=utf8',
rabbit_userid => 'nova',
rabbit_password => 'an_even_bigger_secret',
image_service => 'nova.image.glance.GlanceImageService',
glance_api_servers => 'localhost:9292',
verbose => false,
rabbit_host => '127.0.0.1',
}
class { 'nova::compute':
enabled => true,
vnc_enabled => true,
}
class { 'nova::compute::libvirt':
migration_support => true,
}
Implementation
nova
nova is a combination of Puppet manifest and ruby code to delivery configuration and extra functionality through types and providers.
Limitations
- Supports libvirt, xenserver and vmware compute drivers.
- Tested on EL and Debian derivatives.
Development
Developer documentation for the entire puppet-openstack project.
Beaker-Rspec
This module has beaker-rspec tests
To run the tests on the default vagrant node:
bundle install
bundle exec rspec spec/acceptance
