2017-07-19 20:24:49 -0500 asked a question Deploy from undercloud or controller?

Hello, I have a Redhat Openstack 7 setup with 3 controllers and 20 computes.

I want to know the absolutely correct way to deploy a stack, whether from first logging in the undercloud and then sourcing the overcloud, or login to the controller then source the overcloud and deploy the stack from there?

What are the drawbacks of deploying a stack either way?

If deploying the stack from the controller will it use all the resources as it would when sourcing the overcloud from the undercloud?

Can problems or issues arise later from deploying one way or the other?

Thanks for the help..
