Comment 5 for bug 1869211

I'd also like to move to using K8S hosted Juju controllers for OpenStack Sunbeam.

This would significantly reduce the complexity of operations such as major or minor juju upgrades (which now require model migrations to a controller of the target version) - creating a new controller under K8S and then migrating models to it should be very repeatable/reliable and would avoid the use of another technology in sunbeam (LXD) to deal with multiple controller installations on the same set of machines in order to support upgrades.

Would love to see this feature bumped in priority :)
