hi
@Atish Dubey - we can wait for some feedback from the community as others may have better information, but short term: here is an older archived guide from our Fleet documentation
https://fleetdm.com/guides/deploy-fleet-on-kubernetes
this guide is no longer maintained so i can't guarantee that they are the exact steps needed to get things working as our best practice / recommended deployment path is on AWS or Render, but we do have several customers who have deployed on kubernetes in the past.
