I’ve previously bootstrapped a public cloud of a similar size using Foreman and Puppet.  However, that was over five years ago - if I was doing it again today I’d go with Kolla-Ansible.  Point taken regarding the documentation, but if you can make your way onto Freenode you’ll find the folks in #openstack-kolla a very helpful bunch.

As an simpler alternative to Triple-O, I’d also recommend you take a look at Kayobe: https://kayobe.readthedocs.io/en/latest/ or for a brief introduction: https://www.slideshare.net/MarkGoddard2/to-kayobe-or-not-to-kayobe

Again, if you’re on Freenode then give us a shout in #openstack-kayobe

Good luck!

Hi Melvin and Arkady,

Thank you for the replies.

I have been using TripleO on a small scale (10~20 nodes per
deployment) and it worked well. That said, I am not sure what capacity
it is designed for and whether it is still suitable to go beyond 2~300
nodes.

@Melvin: I attempted to try Kolla-Ansible and OpenStack-Ansible, but
failed to find documentations that provide coverages as detail as
TripleO's. Do you happen to know any resources or books on the
subjects for me to work on?

@Arkady: May I ask if you used a Spine/Leaf network topology (i.e.
using a fully meshed layer 3 network above ToR) to deploy the 3 racks?

Thank you to all!

Best regards,
Cody

We had done TripleO deployment with 3 racks several times and it worked fined.

Personally I have found openstack-ansible to be robust and very useful for a production environment. Not only the tool itself but also the help offered by those whose develop and use it. There is a bit of a learning curve however. At the end of the day I think the best solution is the one that works for you and if you have a chance you should try each one to see which is most suitable. I have not tried TripleO, Airship in a bottle did not work out the box, Kolla-Ansible is useful also but gave me fits troubleshooting, and OpenStack-Ansible I mentioned the learning curve. I do not deal with a lot of manual deploying these days but if I was spinning up a public cloud personally I would roll with OpenStack-Ansible

Hello stackers,

What deployment tools would be of your choice for deploying a public
IaaS with an initial size of 200~300 nodes? Would TripleO be suitable
for this cluster size?

Thank you very much. Wish you all a happy holiday season!

Best regards,
