Thanks for this nice tutorial @Soap2G.

I would structure a bit differently the tutorial. I would make a first "CERN infrastructure" section in where I would describe how to set up all the infrastructure (OpenStack, k8s, DBOD, LANDB etc...). And later on another section all the rest, that is general and common once you have a k8s cluster up and running.

I also find that this documentation is a k8s tutorial in the end, so maybe it will be nice to put it on the k8s-tutorial rucio repo.
