1) Is there any existing example of deployment documents (site, global?

There is some documentation here : https://treasuremap.readthedocs.io/en/latest/deployment.html#building-site-documents and https://pegleg.readthedocs.io/en/latest/artifacts.html but a concrete example would really help people outside of ATT to get started and understand it.

I see that there are Jenkins pipelines downloading some files here : https://github.com/att-comdev/cicd/blob/master/integration/genesis-full/Jenkinsfile

I have a 7 nodes cluster that I deployed using the default values here : https://github.com/openstack/openstack-helm/tree/master/tools/deployment/armada and I'm really happy with Airship but I would like to go further :)

2) Also, how to add another node in an existing cluster after genesis and openstack deployed on it?

Best,

James
