Environment requirements
You will need the Openstack OpenStack Client and the Octavia plugin.

How to deploy a basic HTTP load balancer
...
with an associated floating-IP
We will walk you through the steps to create a setup where two instances running nginx servers are connected to an HTTP load balancer. The load balancer will use the round-robin algorithm to evenly distribute incoming HTTP traffic across the two servers. This configuration will help distribute incoming traffic across the two servers. In this use case, we will create a ...
Prerequisites
Before creating a load balancer, ensure that the following resources are
...
available in your tenant:
- 1 network.

- Desired security groups for the VMs.
- 2 instances
- At least 3 floating IP: two associated to the VMs and an additional one available for the load balancer and the other two associated to the VMs.
If you need to create these resources, you can follow our user guides.
Procedure

(Note: Wait until creation is completed. It will take a while and the next steps will return an error if the load balancer is not available.
