But I also agree with the below sentiments that we need to properly document and enable folks to do more complex deployments after they've had their first success with the minimal deployment option One thing to consider in all of this is... what is the minimum deployment footprint? I think we have to assume virtual, since most folks won't have a lab with 6 nodes sitting around. A few options: a Undercloud on one VM, single overcloud controller on another VM, single compute node on another VM (using nested virt, or just plain emulation) b 2nd variation on the above would be to run the 3 node controller HA setup, which means 1 undercloud, 3 overcloud controllers + 1 compute The question is... what is the minimum amount of RAM that you can run an overcloud controller with? 4GB? Or can that be squeezed to 2 or 3GB just for playing around purposes? What is the minimum amount of RAM you need for the undercloud node? If 4GB per VM, then a) maybe can be done on a 16GB system, while b) needs 32GB

If we could squeeze controller and undercloud nodes into 3GB each, then it might be possible to run b) on a 16GB machine, opening up experimentation with RDO Manager in a real HA configuration to lots more people Perry _______________________________________________ Rdo-list mailing list Rdo-list(a)redhat.com https://www.redhat.com/mailman/listinfo/rdo-list To unsubscribe: rdo-list-unsubscribe(a)redhat.com
