2020/06/16
 
Install and Configure OpenStack Load Balancing as a Service (Octavia).
This example is based on the environment like follows.
Configured Networking is VXLAN like here on this environment.

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

root@dlp ~(keystone)#
snap install octavia-diskimage-retrofit --beta --devmode

root@dlp ~(keystone)#
cd /var/snap/octavia-diskimage-retrofit/common/tmp

root@dlp tmp(keystone)#
wget https://cloud-images.ubuntu.com/minimal/releases/bionic/release/ubuntu-18.04-minimal-cloudimg-amd64.img

root@dlp tmp(keystone)#
octavia-diskimage-retrofit ubuntu-18.04-minimal-cloudimg-amd64.img ubuntu-amphora-haproxy-amd64.qcow2
# add to Glance

root@dlp ~(keystone)#
openstack image create "Amphora" --tag "Amphora" --file ubuntu-amphora-haproxy-amd64.qcow2 --disk-format qcow2 --container-format bare --private --project service
# add [flavor] for Amphora instance

root@dlp ~(keystone)#
openstack flavor create --id 100 --vcpus 1 --ram 1024 --disk 5 m1.octavia --private --project service
# add a security group for Amphora instance

root@dlp ~(keystone)#
openstack security group create lb-mgmt-sec-group --project service
# allow required ports for security group

root@dlp ~(keystone)#
openstack security group rule create --protocol icmp --ingress lb-mgmt-sec-group

root@dlp ~(keystone)#
openstack security group rule create --protocol tcp --dst-port 22:22 lb-mgmt-sec-group

root@dlp ~(keystone)#
openstack security group rule create --protocol tcp --dst-port 80:80 lb-mgmt-sec-group

root@dlp ~(keystone)#
openstack security group rule create --protocol tcp --dst-port 443:443 lb-mgmt-sec-group

root@dlp ~(keystone)#
openstack security group rule create --protocol tcp --dst-port 9443:9443 lb-mgmt-sec-group

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