Ihar Hrachyshka 089e60a68b Migrate to oslo.context 
That's just a matter of adding requirements.txt entry, fixing imports,
and dropping the corresponding oslo-incubator module from the tree.

While at it, made all imports to import the module into 'oslo_context' and
not just 'context', so that we don't override the module locally in
multiple methods that receive their context arguments with the same
name, making the library inaccessible from inside those methods.

Brocade Openstack Neutron Plugin

Openstack Brocade Neutron Plugin implements the Neutron v2.0 API.

This plugin is meant to orchestrate Brocade VCS switches running NOS, examples of these are:

  1. VDX 67xx series of switches
  2. VDX 87xx series of switches

Brocade Neutron plugin implements the Neutron v2.0 API. It uses NETCONF at the backend to configure the Brocade switch.

Directory Structure

Normally you will have your Openstack directory structure as follows:

     /opt/stack/nova/
     /opt/stack/horizon/
     ...
     /opt/stack/neutron/neutron/plugins/

Within this structure, Brocade plugin resides at:

     /opt/stack/neutron/neutron/plugins/brocade

Prerequsites

This plugin requires installation of the python netconf client (ncclient) library:

ncclient v0.3.1 - Python library for NETCONF clients available at http://github.com/brocade/ncclient

% git clone https://www.github.com/brocade/ncclient % cd ncclient; sudo python ./setup.py install

Configuration

  1. Specify to Neutron that you will be using the Brocade Plugin - this is done by setting the parameter core_plugin in Neutron:

     core_plugin = neutron.plugins.brocade.NeutronPlugin.BrocadePluginV2

  2. Physical switch configuration parameters and Brocade specific database configuration is specified in the configuration file specified in the brocade.ini files:

     % cat /etc/neutron/plugins/brocade/brocade.ini
 [SWITCH]
 username = admin
 password = password
 address  = <switch mgmt ip address>
 ostype   = NOS

 [database]
 connection = mysql://root:pass@localhost/brocade_neutron?charset=utf8

 (please see list of more configuration parameters in the brocade.ini file)

Running Setup.py

Running setup.py with appropriate permissions will copy the default configuration file to /etc/neutron/plugins/brocade/brocade.ini. This file MUST be edited to suit your setup/environment.

  % cd /opt/stack/neutron/neutron/plugins/brocade
  % python setup.py

Devstack

Please see special notes for devstack at: http://wiki.openstack.org/brocade-neutron-plugin

In order to use Brocade Neutron Plugin, add the following lines in localrc, if localrc file doe not exist create one:

ENABLED_SERVICES=g-api,g-reg,key,n-api,n-crt,n-obj,n-cpu,n-net,n-cond,cinder,c-sch,c-api,c-vol,n-sch,n-novnc,n-xvnc,n-cauth,horizon,rabbit,neutron,q-svc,q-agt Q_PLUGIN=brocade

As part of running devstack/stack.sh, the configuration files is copied as:

% cp /opt/stack/neutron/etc/neutron/plugins/brocade/brocade.ini /etc/neutron/plugins/brocade/brocade.ini

(hence it is important to make any changes to the configuration in: /opt/stack/neutron/etc/neutron/plugins/brocade/brocade.ini)
