Overview

The neutron 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 flexibly configure and manage the network service for OpenStack.

Module Description

The neutron module is an attempt to make Puppet capable of managing the entirety of neutron. This includes manifests to provision such things as keystone endpoints, RPC configurations specific to neutron, database connections, and network driver plugins. Types are shipped as part of the neutron module to assist in manipulation of the OpenStack configuration files.

This module is tested in combination with other modules needed to build and leverage an entire OpenStack installation.

Setup

What the neutron module affects:

  • Neutron, the network service for OpenStack.

Installing neutron

puppet module install openstack/neutron

Beginning with neutron

To utilize the neutron module's functionality you will need to declare multiple resources. The following example displays the setting up of an Open vSwitch neutron installation. This is not an exhaustive list of all the components needed. We recommend that you consult and understand the core openstack documentation to assist you in understanding the available deployment options.

# enable the neutron service
class { '::neutron':
  enabled               => true,
  bind_host             => '127.0.0.1',
  default_transport_url => 'rabbit://neutron:passw0rd@localhost:5672/neutron',
  debug                 => false,
}

class { 'neutron::server':
  database_connection => 'mysql+pymysql://neutron:neutron_sql_secret@127.0.0.1/neutron?charset=utf8',
}

class { 'neutron::keystone::authtoken':
  password => 'keystone_neutron_secret',
}

# ml2 plugin with vxlan as ml2 driver and ovs as mechanism driver
class { 'neutron::plugins::ml2':
  type_drivers         => ['vxlan'],
  tenant_network_types => ['vxlan'],
  vxlan_group          => '239.1.1.1',
  mechanism_drivers    => ['openvswitch'],
  vni_ranges           => ['1:300']
}

Other neutron network drivers include:

  • dhcp,
  • metadata,
  • and l3.

Nova will also need to be configured to connect to the neutron service. Setting up the nova::network::neutron class sets the network_api_class parameter in nova to use neutron instead of nova-network.

class { 'nova::network::neutron':
  neutron_password  => 'neutron_admin_secret',
}

The examples directory also provides a quick tutorial on how to use this module.

Implementation

neutron

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

Types

neutron_config

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

neutron_config { 'DEFAULT/core_plugin' :
  value => ml2,
}

This will write core_plugin=ml2 in the [DEFAULT] section.

name

Section/setting name to manage from neutron.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

This module supports the following neutron plugins:

  • Open vSwitch with ML2
  • linuxbridge with ML2
  • Arista with ML2
  • cisco-neutron with and without ML2
  • NVP
  • PLUMgrid

The following platforms are supported:

  • Ubuntu 12.04 (Precise)
  • Debian (Wheezy)
  • RHEL 6
  • Fedora 18

Beaker-Rspec

This module has beaker-rspec tests

To run:

bundle install
bundle exec rspec spec/acceptance

Development

The puppet-openstack modules follow the OpenStack development model. Developer documentation for the entire puppet-openstack project is at:
