Neat! Maybe out of place but is there something similar where a virtual machine is spun up rather than docker?

  That's actually something I've been discussing with a colleague - Nix is capable of building various other image types (netboot, qemu, etc.) and we could theoretically extend Nixery to provide such images in addition.

    (I know almost nothing about Nix, so take this question loosely) Do you know if there's an easy way to generate a Docker container from a Nix script? That could be a very nice alternative to a Dockerfile.
    • tazjin 7y ago
      Yes, you can do that using for example `buildLayeredImage`: { pkgs ? import <nixpkgs> {} }: with pkgs; dockerTools.buildLayeredImage { name = "curl-bash"; contents = [ curl bashInteractive coreutils ]; } Putting that in a file and calling `nix-build` on that file will give you a tarball that Docker will happily load using `docker load`. Doing this has a lot of advantages over Dockerfiles, see this blog post for some of the others: https://grahamc.com/blog/nix-and-layered-docker-images https://grahamc.com/blog/nix-and-layered-docker-images

        Fantastic, thanks!

  That can be made a runtime concern - if you use Kata Containers as a runtime for Docker, it'll use a VM instead of kernel namespaces.
