| [ Control Node ] | | [ Storage Node ] | | [ Compute Node ] |
| | | | | |
| MariaDB RabbitMQ | | Open vSwitch | | Libvirt |
| Memcached httpd | | Neutron Server | | Nova Compute |
| Keystone Glance | | OVN-Northd | | Open vSwitch |
| Nova API | | Cinder Volume | | OVN Metadata Agent |
| Cinder API | | Octavia Services | | OVN-Controller |

|
| [1] | Install Octavia services. For questions duruing the installation, it's OK with [No] to all. |
|
root@network:~# apt -y install octavia-api octavia-health-manager octavia-housekeeping octavia-worker python3-ovn-octavia-provider
|
| [2] | Create certificates that are used among LoadBalancer Instance and Octavia services. |
