Open Stack

You should probably try openstack-operators mailing list next time, as
openstack-dev is more developer oriented. But anyway:

According to latest OpenStack User Survey [1] most popular tools are
either Puppet or Ansible. There are OpenStack projects maintaining
manifests or playbooks for both of them (and more).

There are efforts to standardize OpenStack between deployments, so
convenient ways of injecting your own code are currently being
deprecated and removed. See nova hooks for example [2].

Then you may want to look at Kolla project [3], as it deploys OpenStack
in Docker containers and provides automated procedure allowing upgrade
between releases with minimal downtime.
