List,

I want to install Openstack Xena version on a DELL ( R650 2 CPU and 40 cores . 2.4 TB) server machine. Operating System preference is Debian 10. I want to deploy this for production use with Ceph OSDs.

There are four methods described in the URL : Confused which to select.

https://docs.openstack.org/xena/deploy/

1. Using Charms deployment i think this mainly targets ubuntu not debian 2. Deploy openstack using Ansible in Docker containers 3. Openstack - Ansible Deployment guide. for both of the above i would suggest looking at kolla-ansible or openstack ansible (OSA) my personal prefernce between the two is kolla but both are production ready deploymnets with good upgrade support and fast release cadnace following a new upstream release. both support debian as far as im aware too. 4. Triple O deployment guide if you want to use debian triplo is not an option

there is aly the option of the debian openstack installer. zingo can tell you more about that. i have not personlly used it but i hear good things about it i belive its based on puppet which is not really my preference im much more partial to ansible based installers but if debian 10 is what you are targeting its proably a good option to consider. https://lists.openstack.org/pipermail/openstack-discuss/2022-August/029910.h... there was an anounchment about deabin lts/10 exteding there lts supprot for rocky recently so its well maintianed long term. kolla is still my preference but that is more as a developer and home user for its simplicity and feature set. OSA or the Debian installer might suite you bettter depending on your usecase. in general i would recommend using an existing installer for openstack vs creating your own or using the puppet/ansible moduels to build your own. long term if you use an excisting installer you will benifit form the maintaince and skill set of the comunity that maintain it.

Which method do I have to follow a full fledged production deployment ?

why ?

Going ahead with Ansible and Docker is a best option or not ?

most installers provide fully ha production ready deployments. i would recomend mangain ceph externally via cephadm regardless of how you deploy openstack. that is what kolla does i think its a solid option for many usecases if you dont like docker or down want contaienrs you dont have to use them to deploy openstack

Your kind guidance requested..

Thanks in advance, Krish

ps:-

Once Completed this installation I have to extend this as a High available(HA) Multi Node cloud. (multi node production cloud with 3 Controllers, 6 compute Nodes and 3 Storage nodes with Ceph OSD pools) . Request to consider this future scalability requirement while answering my query.
