Allow customisation of the algorithm used to convert nix references graph (created from docker image contents) to docker layers. A collection of building blocks (python functions) is provided, which use can assembled into a processing pipeline by specifying a list of operations (and their initial arguments) via a nix list. Nix references graph if first converted into a python igraph.Graph object (with each vertex representing a nix path), which is then fed into the user defined pipeline. Each stage in the pipeline represents a function call, with initial arguments specified by the user in nix, and the last argument being the result of the previous stage in the pipeline (or the initial Graph object). Each step of the pipeline is expected to produce a data structure consisting of arbitrarily nested lists/dicts with Graph objects (representing docker layers) at it's leafs. The result of the last stage in the pipeline is recursively flattened (with each dict converted into list of values), until a flat list of Graphs remains. This is then output as a json array of arrays (each Graph converted into an array of paths). This functionality is made available via new `layeringPipeline` argument to the `streamLayeredImage`/`buildLayeredImage` functions. The default value of the argument has been chosen to to preserve current layering behaviour. Co-authored-by: Sandro <sandro.jaeckel@gmail.com> |

Nixpkgs is a collection of over 100,000 software packages that can be installed with the Nix package manager. It also implements NixOS, a purely-functional Linux distribution.

Other Project Repositories
The sources of all official Nix-related projects are in the NixOS organization on GitHub. Here are some of the main ones:
- Nix - the purely functional package manager
- NixOps - the tool to remotely deploy NixOS machines
- nixos-hardware - NixOS profiles to optimize settings for different hardware
- Nix RFCs - the formal process for making substantial changes to the community
- NixOS homepage - the NixOS.org website
- hydra - our continuous integration system
- NixOS Artwork - NixOS artwork
Continuous Integration and Distribution
Nixpkgs and NixOS are built and tested by our continuous integration system, Hydra.
- Continuous package builds for unstable/master
- Continuous package builds for the NixOS 24.05 release
- Tests for unstable/master
- Tests for the NixOS 24.05 release
Artifacts successfully built with Hydra are published to cache at https://cache.nixos.org/. When successful build and test criteria are met, the Nixpkgs expressions are distributed via Nix channels.
Contributing
Nixpkgs is among the most active projects on GitHub. While thousands of open issues and pull requests might seem a lot at first, it helps consider it in the context of the scope of the project. Nixpkgs describes how to build tens of thousands of pieces of software and implements a Linux distribution. The GitHub Insights page gives a sense of the project activity.
Community contributions are always welcome through GitHub Issues and Pull Requests.
For more information about contributing to the project, please visit the contributing page.
Donations
The infrastructure for NixOS and related projects is maintained by a nonprofit organization, the NixOS Foundation. To ensure the continuity and expansion of the NixOS infrastructure, we are looking for donations to our organization.
You can donate to the NixOS foundation through SEPA bank transfers or by using Open Collective:
