is it possible to install sonata without openstack

[parmentelat]

hiya

I have a very general question, I hope this is an OK place to ask

we're looking for a solution that would allow to orchestrate several k8s-based clusters; there is no VM-based cluster in the landscape, and so I was curious to know if it's possible to use sonata in such a use case - given that the docs that I have seen suggest otherwise (that openstack is mandatory)

I am referring specifically to this quote that I found in https://sonata-nfv.github.io/quickguide

Setup
To setup SONATA you must install the three major components of SONATA and OpenStack in the order shown is the following bulleted list and as highlighted in the following diagram.

thanks in advance for your insights
