doc: Update LBaaS v2 setup for Liberty
- Updated LBaaS v2 setup to use Octavia. - Removed the old cirros image URL, the default should be sufficient. - Fixed nova boot commands based on Liberty DevStack. - Added sleeps to LBaaS v2 commands since most commands can take a few seconds to complete. - Added wait to load balancer creation since it can take a few minutes to complete. - Wrapped long lines in the descriptions.

Configure Load-Balancer in Kilo
|
||||
Configure Load-Balancer Version 2
|
||||
=================================
|
||||
|
||||
The Kilo release of OpenStack will support Version 2 of the neutron load balancer. Until now, using OpenStack `LBaaS V2 <http://docs.openstack.org/api/openstack-network/2.0/content/lbaas_ext.html>`_ has required a good understanding of neutron and LBaaS architecture and several manual steps.
|
||||
Starting in the OpenStack Liberty release, the
|
||||
`neutron LBaaS v2 API <http://developer.openstack.org/api-ref-networking-v2-ext.html>`_
|
||||
is now stable while the LBaaS v1 API has been deprecated. The LBaaS v2 reference
|
||||
driver is based on Octavia.
|
||||

||||

||||
Phase 1: Create DevStack + 2 nova instances

|
||||
First, set up a vm of your choice with at least 8 GB RAM and 16 GB disk space, make sure it is updated. Install git and any other developer tools you find useful.
