Open Stack

Hi there, i am trying to get Octavia running on a Victoria deployment on 
CentOS 8. It was a bit rough getting to the point to launch an instance 
mainly due to the load-balancer management network and the lack of 
documentation 
(https://docs.openstack.org/octavia/victoria/install/install.html) to 
deploy this oN CentOS. I will try to fix this once I have my deployment 
up and running to help others on the way installing and configuring this :-)

At this point a LB can be launched by the tenant and the instance is 
spawned in the Octavia project and I can ping and SSH into the amphora 
instance from the Octavia node where the octavia-health-manager service 
is running using the IP within the same subnet of the amphoras 
(172.16.0.0/12).

Unfortunately I keep on getting these errors in the log file of the 
worker log (/var/log/octavia/worker.log):

2021-05-05 01:54:49.368 14521 WARNING

2021-05-05 01:54:54.374 14521 ERROR 
octavia.controller.worker.v1.tasks.amphora_driver_tasks [-] Amphora 
compute instance failed to become reachable. This either means the 
compute driver failed to fully boot the
instance inside the timeout interval or the instance is not reachable 
via the lb-mgmt-net.: 
octavia.amphorae.driver_exceptions.exceptions.TimeOutException: 
contacting the amphora timed out

obviously the instance is deleted then and the task fails from the 
tenant's perspective.

The main issue here is that there is no service running on port 9443 on 
the amphora instance. I am assuming that this is in fact the 
amphora-agent service that is running on the instance which should be 
listening on this port 9443 but the service does not seem to be up or 
not installed at all.

To create the image I have installed the CentOS package 
"openstack-octavia-diskimage-create" which provides the utility 
disk-image-create but from what I can conclude the amphora-agent is not 
being installed (thought this was done automatically by default :-( )

Can anyone let me know if the amphora-agent is what gets queried on port 
9443 ?

If the agent is not installed/injected by default when building the 
amphora image?

The command to inject the amphora-agent into the amphora image when 
using the disk-image-create command?

Thanks in advance for any assistance
