PLUMgrid Fuel Plugin

The PLUMgrid plugin for Fuel provides the capability to use PLUMgrid ONS as the entire network backend for Mirantis OpenStack. This installs the PLUMgrid core neutron plugin in collaboration with PLUMgrid Director, Edge and Gateway components to provide a virtual network infrastructure for the Cloud.

Problem description

PLUMgrid is a core neutron networking plugin that has been a part of OpenStack neutron since Grizzly. It offers a Network Virtualization Platform that uses direct communication with the Hypervisor layer to provide all the networking functionality requested through Neutron APIs. The PLUMgrid Neutron Plugin implements Neutron v2 APIs and helps configure L2/L3 virtual networks created through the PLUMgrid Platform. It also implements External Networks and Port Binding Extensions.

APIs supported by the PLUMgrid plugin:
  • Networks
  • Subnets
  • Ports
  • External Networks
  • Routers
  • Security Groups
  • Quotas
  • Port Binding
  • Provider Networks

Proposed changes

Implement a Fuel plugin that deploys PLUMgrid as the core neutron plugin and configure Mirantis OpenStack to use PLUMgrid as the networking backend.

The plugin deployment will also include deploying PLUMgrid Zone components which reside on the controller and compute nodes to interact with the cluster. A new role will also be created to deploy PLUMgrid Gateway nodes. These Gateway nodes reside outside of the OpenStack cluster and are deployed over standard Ubuntu servers.

Alternatives

None.

Upgrade impact

Upgrading the Fuel PLUMgrid plugin will be possible through the standard fuel cli. Also upgrading the PLUMgrid ONS version will be possible through re-running post_deployment tasks after pointing to a repository with newer PLUMgrid packages.

Security impact

None.

Notifications impact

None.

End user impact

End users will be able to leverage the enhanced scale and operational capabilities provided by the PLUMgrid plugin when choosing to install this plugin. Further details can be found in the References section below.

Performance impact

Same as End user impact.

Deployment impact

The PLUMgrid plugin tasks all run in post_deployment stage.

Developer impact

None.

Documentation impact

Documentation describing how to configure the Fuel UI PLUMgrid plugin parameters to install PLUMgrid, will be provided with the plugin. This will be deployer documentation.
