Fuel Plugin for Juniper Contrail SDN integration

Contrail plugin for Fuel provides the functionality to add Сontrail SDN for Mirantis OpenStack as networking backend option.

It uses Fuel pluggable architecture. The plugin must be compatible with the version 6.1 of Mirantis OpenStack and Contrail 2.0.22. Only HA mode for OpenStack and Contrail controllers is supported. It will be allowed to deploy an only Contrail Controller (for test-bed environments) and add more controllers later (to enable true HA). Contrail Load-Balancing-as-a-Service feature available through OpenStack Neutron API can be enabled.

Problem description

Proposed change

Implement a Fuel plugin which will deploy Contrail SDN controllers and configure Mirantis OpenStack to use Contrail as Neutron plugin.

Alternatives

It also might be implemented as a part of Fuel core, but we decided to make it as a plugin for several reasons:

  • Any new additional functionality makes a project and testing more difficult, which is an additional risk for the FUEL release.

Data model impact

REST API impact

Upgrade impact

Fuel currently supports upgrading of Fuel Master node, so it is necessary to install a new version of plugin which supports new Fuel release.

Security impact

Notifications impact

Other end user impact

Contrail plugin uses Fuel pluggable architecture. After it is installed, the user can enable the plugin on the Setting tab of the Fuel web UI and customize plugins settings.

Performance Impact

Other deployer impact

Developer impact

Work Items

  • Create pre-dev environment and manually deploy Contrail software
  • Create Fuel plugin bundle, which contains deployments scripts, puppet modules and metadata
  • Implement puppet module with the following functions:
  • Contrail controllers deployment and initial configuration
  • Mirantis OpenStack controllers configuration
  • vRouter deployment on OpenStack compute nodes
  • Test Contrail plugin
  • Create Documentation

Dependencies

  • Fuel 6.1 and higher
  • Base-os node role
  • Node reboot task
  • Advanced networking in Fuel

Testing

  • Sanity checks including plugin build
  • Syntax check
  • Functional testing
  • Non-functional testing (Destructive and Negative)

Documentation Impact

  • Deployment Guide (how to prepare an env for installation, how to install the plugin, how to deploy OpenStack env with the plugin)
  • User Guide (which features the plugin provides, how to use them in the deployed OS env)
  • Test Plan
  • Test Report
