Deploying Neutron LBaaS With Devstack

Install devstack with neutron and neutron lbaas
- Following the instructions on this link should suffice. It will enable the v1 lbaas API
- http://roaet.com/my-method-to-installuse-devstack
Pull down gerrit change requests with useable code
- LoggingNoopDriver
  - https://review.openstack.org/#/c/105610/
- Agentless Haproxy Driver
  - https://review.openstack.org/#/c/108174/
Change the neutron config
- /etc/neutron/neutron.conf
  - Under the [DEFAULT] section there is an options called service_plugins. It is a comma-delimited list. Add the following to it:
    - If service_plugins option already exists add to the end of the line:
      - ,neutron.services.loadbalancer.plugin.LoadBalancerPluginv2
    - If service_plugins option does not exist add this line:
      - service_plugins = neutron.services.loadbalancer.plugin.LoadBalancerPluginv2
  - Under the [service_providers] section (usually at the bottom) there are options called service_provider, there can be many service_provider entries. Add the following
    - To use the LoggingNoopDriver:
      - service_provider=LOADBALANCERV2:LoggingNoop:neutron.services.loadbalancer.drivers.logging_noop.driver.LoggingNoopLoadBalancerDriver:default
    - To use the Agentless Haproxy Driver:
      - service_provider=LOADBALANCERV2:Haproxy:neutron.services.loadbalancer.drivers.haproxy.nonagent_namespace_driver.HaproxyNSDriver:default
Re-install the neutron code and restart the neutron-server process. This is most easily done by going into the devstack screen, switching to neutron server (^A-6), hitting ^C, up arrow, enter. Alternately:
- I use this bash script:

#!/bin/bash

if [ `ps aux | grep neutron-server | wc -l` -gt 1 ]; then
    kill -9 `ps aux | grep '[n]eutron-server' -m1 | awk '{print $2}'`
fi
