OpenStack Epoxy : Create LoadBalancer Image

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 +-----------+-----------+ +-----------+-----------+ +-----------+-----------+ | [ dlp.srv.world ] | | [ network.srv.world ] | | [ node01.srv.world ] | | (Control Node) | | (Network Node) | | (Compute Node) | | | | | | | | MariaDB RabbitMQ | | Open vSwitch | | Libvirt | | Memcached Nginx | | Neutron Server | | Nova Compute | | Keystone httpd | | OVN-Northd | | Open vSwitch | | Glance Nova API | | Nginx iSCSI Target | | OVN Metadata Agent | | Cinder API | | Cinder Volume | | 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)

[2]	Configure Octavia service to set instance ID or security group ID.
