tl;dw - individual containers isolated in HVMs with traditional container tooling.

I have been living under a rock and had not heard of this project before. it does seem to give a reasonable alternative to the manual VM[container] two-step for some workloads.

an older, but more complete intro lives at Kata Containers An introduction and overview [you tube]

Is this useful for a homelab with a current setup of 1 physical host -> proxmox -> alpine VM -> docker?

Docker is managed by portainer that pulls docker compose files from a git repo. Around 30 containers total in 10 or so stacks.

This idea looks really interesting but it seems to be mostly for kubernetes deployments
