Deploying Octavia

To deploy Octavia as part of an Openstack deployment just add the --octavia overlay. Once deployed there are a few actions that must be taken to configure Octavia before it can be used.

NOTE: if you are using OVN as your neutron networking solution, you will need to perform the steps detailed in the ovn documentation before continuing

Post-deployment configuration

The following will download the Amphora image from (stsstack) Swift that corresponds to the deployed release of Openstack and upload it to your Glance.

The following will configure Octavia’s TLS certificate and lb-mgmt network.

Using Octavia

1. Create an instance and security group rules

   source novarc
   ./tools/sec_groups.sh &>2 &
   ./tools/instance_launch.sh 1 jammy
   

2. Give it a floating IP and ensure it can be pinged (once booted)

   ./tools/float_all.sh
   ping __FIP__
   

3. Install Apache

   ssh __FIP__ -- 'sudo apt update; sudo apt install apache2 -y'
   

4. Now create a load balancer adding the VM just created to the LB pool

   tools/create_octavia_lb.sh __VM_UUID__
   

5. Now check that your load balancer is up and load balancing to port 80 in the VM

   lb_vip=$(openstack loadbalancer show lb1 -c vip_address -f value)
   lb_fip=$(openstack floating ip list --fixed-ip-address ${lb_vip} -f value -c floating_ip_address)
   nc -vz ${lb_fip} 80
