If you want a single-node deployment, I suggest Packstack. Devstack is not bad either, but its purpose is testing OpenStack code, whereas Packstack is marketed as a proof-of-concept tool. Devstack is harder to configure except very simple clouds, and I don't know if an existing Devstack cloud can be expanded to a multi-node cloud. Packstack allows adding compute nodes with ease.

Main limitation of Packstack: It requires Centos/Red Hat.

If you want to get your hands dirty, set up two nodes and use the installation tutorial. Much harder, but you learn more.

There are many other deployment tools, some of them are part of the OpenStack project. Kolla/Ansible installs all OpenStack services in Docker containers and has documentation for a single-node setup. OpenStack Ansible uses Linux Containers (LXC) and also has a single-node solution they call all-in-one (AIO).

Have you tried to install it? Any problems?

You can also try official repo https://github.com/openstack/openstack-ansible to install openstack via ansible playbooks as well.

I'm using, for my lab, the solution offered of Ubuntu via conjure-up, here the https://www.ubuntu.com/openstack/install (link). Then, dependent how you want to create your environment on a single node or in cluster node. I can suggest you this https://docs.openstack.org/project-deploy-guide/charm-deployment-guide/rocky/install-maas.html (link) with Maas and Juju.

you can also try using kolla-ansible for deploying an all-in-one environment. https://docs.openstack.org/kolla-ansi...

Without knowing cause and function of commands, parameters and packages in openstack installation you will not be able to play with your cloud structure.

if you want to learn how openstack functions and how it should be installed i really do suggest that you read manual installation guides carefully and try to implement them in order in if any error happened there, you can search here and find solution for most of your questions. its the hard way, but the best way to learn. if you want to just run openstack for other reasons than learning, its better to use something like juju or devstack or ask someone to deploy the stack for you.
