Unlike its cartoon namesake Jimmy Neutron, OpenStack Neutron has an extensible plugin mechanism that enables more network features through the Neutron API. By enabling the Load-Balancer-as-a-Service (LBaaS) agent plugin on our Network node, we are able to create and manage Load Balancers through Neutron API calls. There are drivers for many hardware vendors; the following example uses the HA Proxy reference driver for Open vSwitch.
To install Neutron LBaaS, we install the LBaaS agent on the
network node and configure Neutron on both the
controller nodes to pick up the service.
Ensure that you have a suitable server running the OpenStack network components. If you are using the accompanying Vagrant environment, as described in the Preface, we will use the same
network node for this recipe.
