Configuring the Network Load Balancing Service (Optional)

The OpenStack Networking Service, Neutron, includes a Load Balancer as a Service (LBaaS). This service lets you configure a load balancer that runs outside of your instances and directs traffic to your instances. A common use case is when you want to use multiple instances to serve web pages and want to meet high performance or availability goals.

OpenStack-Ansible currently provides the OpenStack Neutron LBaaS service using HAProxy as the load balancer.

The following procedure describes how to modify the /etc/openstack_deploy/user_variables.yml file to enable LBaaS.

  1. Override the default list of Neutron plugins used in order to include neutron_lbaas.services.loadbalancer.plugin.LoadBalancerPlugin:

    neutron_plugin_base:
  - neutron.services.l3_router.l3_router_plugin.L3RouterPlugin
  - neutron.services.metering.metering_plugin.MeteringPlugin
  - neutron_lbaas.services.loadbalancer.plugin.LoadBalancerPlugin

  2. Execute the Neutron install playbook in order to update the configuration of the Neutron Agents:

    # cd /opt/openstack-ansible/playbooks
# openstack-ansible os-neutron-install.yml

  3. Execute the Horizon install playbook in order to update the Horizon configuration to show the LBaaS panels:

    # cd /opt/openstack-ansible/playbooks
# openstack-ansible os-horizon-install.yml

The LBaaS default configuration options may be changed through the conf override mechanism using the neutron_lbaas_agent_ini_overrides dict.
