+Configure Load-Balancer in Kilo |
|
| 1 |
+================================= |

+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. |

+Please note here that the "10.0.0.3" and "10.0.0.5" in the above commands are the IPs of the nodes (in my test run-thru, they were actually 10.2 and 10.4), and the address of the created LB will be reported as "vip_address" from the lbaas-loadbalancer-create, and a quick test of that LB is "curl that-lb-ip", which should alternate between showing the IPs of the two nodes. |
