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.

Happy new year Openstack users and devs!

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:

https://bugs.launchpad.net/charm-octavia/+bug/1897418
By default, Octavia charm uses ipv6 for its lb-mgmt-subnet.[1] It would be nice to have the option to choose an ipv4 network from the start instead of deleting the ipv6 network and recreating the ipv4 subnet. Implementation - possible configuration option parameter when deploying. [1] https://opendev.org/openstack/charm-octavia/src/branch/master/src/lib/charm/openstack/api_crud.py#L560

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:

https://docs.openstack.org/octavia/latest/install/install-ubuntu.html#install-and-configure-components
Install and configure for Ubuntu¶. This section describes how to install and configure the Load-balancer service for Ubuntu 18.04 (LTS).

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?

Thanks
