Hi Michael
Thanks for your response. It is useful to know that DNS isn't causing my problems.
I have a few more things I need to try, hopefully I'll get through it today then if I still have issues I will use the charms tag for my next post. ________________________________ From: Michael Johnson johnsomor@gmail.com Sent: 11 January 2021 23:43 To: Daniel Macdonald D.R.MacDonald@salford.ac.uk Cc: openstack-discuss@lists.openstack.org openstack-discuss@lists.openstack.org; Adekunbi Adewojo A.A.Adewojo@edu.salford.ac.uk Subject: Re: [octavia] problems configuring octavia
Hi Daniel,
It might be helpful to use the [charms] in the subject as I think everything you mentioned here is related to the Ubuntu/juju/charms deployment tooling and not the Octavia project. I don't have any experience with doing a deployment with charms, so I can't be of much help there.
That said, Octavia does not rely on DNS for any of its operations. This includes the lb-mgmt-net and for the load balancing elements. So, the lack of access to BIND for Octavia is not a problem.

I have been trying on and off for several months to get octavia working but I have yet to have it successfully create a loadbalancer. I have deployed OS bionic-train using the Charms telemetry bundle with the octavia overlay. Openstack is working for creating regular instances but I get various errors when trying to create a loadbalancer.
The first issue I feel I should mention is that I am using bind running on our MAAS controller as a DNS server. juju doesn't work if I enable IPv6 under bind yet the octavia charm defaults to using IPv6 for its management network so I have tried creating a IPv4 management network but I'm still having problems. For more details on that please see the comments of this bug report:

Another notable issue I have is that after installing the charms telemetry bundle I have 2 projects call services. How do I know which is the correct one to use for Octavia?
Is this following document going to be the best guide for me to follow to complete the final steps required to get Octavia (under Train) working:

I'm hoping someone has already written an easy to follow guide to using Octavia with an IPv4 management network using the Charms bundle to do most of the installation work?
