Again, pardon my ignorance when it comes to Kubernetes. Why would I use something like k0s instead of just regular old Docker? I suspect PCIe passthrough will have similar challenges on both k0s and Docker, whereas on Proxmox it’s been relatively painless.
This might be better suited for a different community, in which case I’ll make a post where appropriate. I’m not familiar with some of the Kubernetes terminology - batteries, pod/manifest (is this similar to stacks/docker compose?), NodePort?
