Open Stack

instead installs components on demand using virtual environments and optionally LXC.

If this is the case, I would rather choose the Docker solution, because I think Docker might be simpler, and a virtualization environment like LXC might be troublesome to configure or manage, because I don't know it.

Yes, this is technology from Canonical and currently it runs reliably only on Ubuntu but one could obviously port it to other systems if they needed.

Kolla (Greek for "glue") deploys using Docker container images (the deployment is done using Kolla Ansible). OpenStack Ansible does not use this approach and instead installs components on demand using virtual environments and (I think still? someone correct me if I'm
wrong) optionally LXC.
Both projects use Ansible but everything else (e.g., the approach to configuration, deployment, upgrades) differs greatly between the two of them.
