As you guys mentioned about both NixOs and k8s

Are you guys install k8s on top of NixOs.

I was thought when using nixOs we tend to go with Dockerless solution.

Currently no, but if we wanted k8s, that’s probably the way we’d go. I’ve done a similar setup in the past, and it’s a bit of an investment to set up, but down the line it absolutely pays of. Specially if you start to also roll your resource files through Nix, can be absurdly powerful!
