Oliver Walsh a47853c485 Include nova::availability_zone in nova::api and nova::conductor
For some reason this was included in nova::compute and nova::scheduler
but never included in nova::api eventhough bug #1529065 specifically
calls out the fact that it is missing.

Looking at the code - nova-api definitely requires it.
E.g the server create request handler sets the target AZ to
CONF.default_schedule_zone if none
https://github.com/openstack/nova/blob/stable/queens/nova/api/openstack/compute/servers.py#L486

and the az request handler skips the internal_service_availabily_zone
when listing AZs
https://github.com/openstack/nova/blob/stable/queens/nova/api/openstack/compute/availability_zone.py#L38

nova-conductor also requires it as it calls
availability_zones.get_host_availability_zone which defaults to
CONF.default_availability_zone

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.

Setup

What the nova module affects:

  • Nova, the compute service for OpenStack.

Installing nova

puppet module install openstack/nova

Beginning with nova

To utilize the nova module's functionality you will need to declare multiple resources. This is not an exhaustive list of all the components needed, we recommend you consult and understand 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',
  glance_api_servers  => 'localhost:9292',
  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.

Types

nova_config

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

nova_config { 'DEFAULT/glance_api_servers' :
  value => 'http://localhost:9292',
}

This will write 'http://localhost:9292' in the [DEFAULT] section.

name

Section/setting name to manage from nova.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

  • 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
