OpenStack Chef Cookbook - network



This cookbook installs the OpenStack Network service Neutron as part of a Chef reference deployment of OpenStack. The OpenStack chef-repo contains documentation for using this cookbook in the context of a full OpenStack deployment. Neutron is currently installed from packages.


OpenStack Network's design is modular, with plugins available that handle L2 and L3 networking for various hardware vendors and standards.


  • Chef 16 or higher
  • Chef Workstation 21.10.640 for testing (also includes Berkshelf for cookbook dependency resolution)


  • ubuntu
  • redhat
  • centos


The following cookbooks are dependencies:

  • 'openstackclient'
  • 'openstack-common', '>= 20.0.0'
  • 'openstack-identity', '>= 20.0.0'


Please see the extensive inline documentation in attributes/*.rb for descriptions of all the settable attributes for this cookbook.

Note that all attributes are in the default['openstack'] "namespace"

The usage of attributes to generate the neutron.conf is described in the openstack-common cookbook.



  • Example bridge recipe used in kitchen tests


  • Migrates the neutron database


  • Configures common pieces needed for all neutron services and create the neutron.conf


  • Installs the DHCP agent

The configuration for neutron-dhcp-agent is generated from the attributes in using the same template as for the neutron.conf



  • Registers the OpenStack Network API endpoint and service user with Keystone


  • Installs the L3 agent

The configuration for neutron-l3-agent is generated from the attributes in using the same template as for the neutron.conf



  • Installs the metadata agent

The configuration for neutron-metadata-agent is generated from the attributes in using the same template as for the neutron.conf



  • Installs the metering agent

The configuration for neutron-metadata-agent is generated from the attributes in using the same template as for the neutron.conf



  • Configure the ml2_core_plugin


  • Configure the ml2 linuxbridge plugin


  • Configure the ml2 openvswitch plugin


  • Installs openvswitch


  • Installs the openvswitch agent


  • Generates all the needed plugin configurations directly from the attributes in:

The final configuration file is generated exactly like all OpenStack service configuration files (e.g. neutron.conf), but the attribute mentioned above allows you additionally to define the file name and patch with:

# this will also generate the path recursively if not already existent
# this defines the filename for the plugin config (e.g. ml2_conf.ini)

In the examples above, the variable myplugin can be used to generate multiple plugin configurations with different configs and filenames. Please refer to the recipe openstack-network::ml2_openvswitch for an full example on the usage of this attributes.


  • Installs the openstack-network API server (currently aka neutron-server)
