|
Install and Configure OpenStack Load Balancing as a Service (Octavia).
This example is based on the environment like follows.
------------+---------------------------+---------------------------+------------

eth0|10.0.0.30 eth0|10.0.0.50 eth0|10.0.0.51
+-----------+-----------+ +-----------+-----------+ +-----------+-----------+
| [ Control Node ] | | [ Network 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 | | iSCSI Target | | OVN-Controller |
| | | Octavia Services | | |

| [1] | Create a LoadBalancer Image and add it to Glance. It's OK to work on any node. (example below is on Control Node) |
