Rally in kubernetes with docker image

Hi Elastic Team,

I would like to perform benchmark Testing for Elasticsearch, I have few questions regarding this:

  1. Can we use rally as a Kubernetes Deployment.
  2. rally/docker at master · elastic/rally · GitHub - I found Docker file here, From this can I build an image and when I use it as a kubernetes deployment will it work?
  3. Is rally linced/ open-source.
  4. When all the above conditions satisfy, still am I going to face any issues.
    Answer will be really appreciated and helpful.

Thanks in advance.

Can Anyone have any idea on this???
