I'm actually using OpenStack-Ansible to deploy a little public cloud. For now
it runs on Queens / Ubuntu 16.04.
I've read that Rocky will be the only release supported on both Ubuntu 16.04
and Ubuntu 18.04 with OpenStack-Ansible.
Stein being out soon (with OpenStack-Ansible), the question of Host OS upgrade
from Ubuntu 16.04 to ubuntu 18.04 is a big thing of this year.
I've not found any documentation about that upgrade path (Rocky->Stein, host
I had some answers on IRC that OpenStack Ansible does not support a mixed
environnement (adding compute nodes on Ubuntu 18.04 while the rest is on
Ubuntu 16.04 for example).
Did I miss something in the actual doc or in some blogs ?
I'm sure some users already faced this with transition fro Ubuntu 14.04 to
Ubuntu 16.04. There's certainly some material to start some documentation and
add it to https://docs.openstack.org/openstack-ansible/stein/admin/upgrades/
I know that there's less contributors now, I'll see if I can help.
