Products that do what Nix Snapshotter – Native understanding of Nix packages for containerd does
Hello! This is Edgar and Robbie and we built nix-snapshotter. nix-snapshotter brings native understanding of Nix packages to containerd. We built this because Nix is a great fit for making efficient containers. They don't need an OS because Nix captures all dependencies exactly. However, the current process of creating Nix images is subpar because one needs to transform Nix packages into a format that container runtimes understand. Using nix-snapshotter, instead of downloading image layers, packages come directly from the Nix store. Packages can be fetched from a binary cache or built on the…

Hi HN, I've been building Nucleus, a lightweight Linux container runtime focused on two workloads: ephemeral AI-agent sandboxes and declarative NixOS services. It's a single Rust binary, no daemon. It is not a Docker replacement and not a strict subset of Docker either. I dropped the entire image-and-distribution half (no Dockerfile, no layers, no registry, no pull/push, no persistent storage layer) in exchange for going deeper on isolation and reproducibility. The rootfs is either a directory copied into tmpfs (agent mode) or a Nix-built closure mounted read-only (production mode). If…

Hi there! I am Edgar and I wanted to share with you “globset”, a Nix library to help specify what sources to include when building a Nix package using familiar glob patterns like “*/*.go”. Nix is package manager and meta build system, in that you glue together compilers and other build systems in repeatable sandboxes like “docker build”. When specifying the source inputs to a Nix package, you typically end up with irrelevant files that when changed causes a rebuild unnecessarily. “globset” provides a concise and simple way of specifying what sources should be included. It is built on…

A fast, rootless sandbox and virtual resource runtime for any workload, including untrusted and AI-generated code. Daemonless: a real, kernel-enforced container in ~3.5 ms from an OCI image, out of one static binary - getkern/kern

ohai! I've released Lightwhale 3, which is possibly the easiest way to self-host Docker containers. It's a free, immutable Linux system purpose-built to live-boot straight into a working Docker Engine, thereby shortcutting the need for installation, configuration, and maintenance. Its simple design makes it easy to learn, and its low memory footprint should make it especially attractive during these times of RAMageddon. If this has piqued your interest, do check it out, along with its easy-to-follow Getting Started guide. In any event, have a nice day! =)

How puffnfresh, my coworker, made a single command to download, assemble, and boot the VM image is arguably as cool as the port itself!

I've been working on getting NixBSD (Nix package manager + FreeBSD) to boot alongside NixOS on a shared ZFS pool. The result is a <2GB disk image you can try in QEMU or virt-manager. What works: - GRUB chainloads FreeBSD's bootloader - Both systems share a ZFS pool - Everything is defined in a single Nix flake - Fully reproducible builds (some dependencies are now cached on Cachix) Planned: - Support native compilation of NixBSD (currently cross-compiled on Linux) - Many shortcuts were taken to get this working, needs lots of cleanup - Add a semi-automated installer like nixos-wizard Try it:…

Try DGX Spark playbooks using Nix on DGX OS, or install NixOS on your DGX Spark for the full Nix experience. The repository provides USB images and a NixOS module with settings for DGX Spark systems. This works on the NVIDIA DGX Spark itself and also on the Asus Ascent GX10. See my 5 minute lightning talk from Planet Nix for an intro: https://youtu.be/AvK_gi_snJE?si=MPKv3iiuS9B5elIE

Nixite generates a bash script to automatically install all your Linux software unattendedly. Nixite prevents prompts and picks the best installation method. Nixite supports Ubuntu-based systems and Arch-based systems. Nixite installs a nixite-updater script to update all package managers and software at once.

Hi! compose2nix is a CLI tool that automatically converts your Docker Compose project into a NixOS configuration[1]. * Why does this even exist? Well, NixOS is a Linux distro that is configured using Nix (the language). However, Compose adds a configuration layer on top that is opaque to Nix, which means you lose out on some of the "magic" of NixOS. compose2nix solves this by "lifting" Compose functionality into native Nix/NixOS constructs, which results in a more native integration with NixOS. In addition, this tool unlocks two primary use-cases: 1. You can run existing non-trivial…

The Darwin kernel (XNU) has been open source since 1999. But "open source" and "you can actually build and boot it" are very different things. XNU depends on proprietary tooling, kexts, and a bunch of open source projects published without a build system. Darnix builds the whole thing with Nix. The kernel, the filesystem, the boot image, all the way to a running QEMU instance. We patched XNU to run on QEMU without kexts, ported HFS+ from a kernel extension into the kernel itself, fixed GRUB's Mach-O loader, and wired it all together as a flake. The build is fully sandboxed. No root, no…

Hi HN! I've posted this a few weeks back without much HN traction - today we've added a free community tier, so anyone can try it out. TL;DR: We’ve launched StableBuild, a new tool to easily freeze and pin Docker images, operating system packages, Python packages, and arbitrary build dependencies; in 5 lines of code: https://stablebuild.com . As the CTO at an ML startup w/ 75 people (https://edgeimpulse.com/) I’ve grown incredibly frustrated with non-deterministic builds. Last year basically every week one of our containers (we have 40+ unique ones in prod)…
