Altocumulus

IMPORTANT This is a proof of concept, it might not even work for your deployment. I'm planning on refactoring this to use the Neutron agent framework as well as Neutron RPC.

Integrate your Cumulus Linux switch with OpenStack Neutron

Manages VLAN bridges on the switch and L2 connectivity between (compute) hosts and the VLAN bridges. Uses LLDP to perform auto-discovery of hosts and the switchports they are connected to.

Uses the same conventions as the Linux Bridge agent so that DHCP/L3 agents can theoretically be hosted on the switch.

Usage

There are two components involved in this project:

• ML2 mechanism driver (runs on hosts with Neutron server)
• HTTP API server (runs on switches)

Installation

ML2 mechanism driver

1. Install the driver and its dependencies with the following

   pip install git+git://github.com/ianunruh/altocumulus.git
   pip install requests

2. Add cumulus to the mechanism_drivers field in /etc/neutron/neutron.conf

3. Configure /etc/neutron/plugins/ml2/ml2_cumulus.ini

HTTP API server

1. Install the API server

   pip install git+git://github.com/ianunruh/altocumulus.git

2. Place the included Upstart script in /etc/init and run start altocumulus-api

To-do

• Authentication
• Pluggable discovery strategies
• Integration with oslo.rootwrap for unprivileged operation
• Working upstart script
