Running vFW without OpenStack



I'm a beginner to ONAP and I want to set up a minimal example of a VNF. From reading through the wiki and past threads, it seems like I should set up vFW (or vFWCL?).
I am looking through this tutorial ( to try to get vFW working. But, the
.env files seem to have a field called cloudEnv, which it says should be set to rackspace or openstack.

I think my OOM isn't working either. I was able to run the deploy command but only dev-cassandra came up.
Is there a tutorial for deploying OOM and then deploying VNFs without using OpenStack (in containers instead)?

Thank you,
