There is also https://nixery.dev/ which lets you get Docker images with arbitrary Nix packages - useful for quick hacking.

Kind of confusing. NixOS vs Nix the language...

You use Nix the language to build Docker images and avoid the NixOS CLI tools/runtime?

[k__]

Nix the package manager.

Nix the language.

NixOS the Linux built with Nix as it's default package manager that uses the Nix language.

[MuffinFlavored]

Nix the language can compile OCI (Open Container Initiative) format images that can be deployed/ran/executed via Docker or k8s?

Or is that Nix the package manager? Does Nix the package manager compile Nix the language images?

[piperswe]

[nixpkgs the package collection] (which is used by [Nix the package manager], and also contains the [Nix the programming language] expressions that define [NixOS the operating system]) has expressions for easily building OCI images: https://nixos.org/manual/nixpkgs/stable/#sec-pkgs-dockerTool...

[MuffinFlavored]

Do you have to be on NixOS to use the OCI images outputtable by nixpks/nix package manager or can you build OCI images using Nix from Mac/Windows/other non NixOS Linux?

No

Non NixOS Unix, not Windows yet, unless you use WSL or a VM

[piperswe]

They're just normal OCI images, so they can be run by any OCI-compatible container runtime. You can build images from any system running Nix, though you might encounter trouble on non-Linux systems because you may need to cross-compile the packages you use. The build process is exactly the same on any Linux distro (including NixOS and anything else) though.

woah - this is great, thanks
