This talk will reflect on what GNU Guix has to offer to users and how it compares to other approaches-from CONDA and pip to Flatpak and Docker. Guix is not only a transactional package manager and declarative GNU/Linux distribution: it’s also an environment manager, a container provisioning tool, and more. We will describe these tools and our journey to 1.0, emphasizing key properties that set Guix apart:
reproducibility, transparency, and hackability.
When it comes to software deployment, we are getting used to a new distribution of roles among many actors: traditional distros take care
of core software pieces, “application bundles” à la Docker/Flatpak provide complex applications, Cabal, Gem, npm, pip, and friends take care of language-specific software, and Puppet/Ansible orchestrate the whole thing. Each of these tools has its justification, but the end result is a maze that’s hard to deal with.
In this talk I will present GNU Guix, a software deployment toolbox and its associated distro that feature transactional upgrades and rollbacks, declarative OS deployment inspired by Nix, and reproducible builds. I will show how Guix approaches a variety of use cases: “package management” à la apt-get, environment management à la VirtualEnv, Ansible-style declarative OS deployment, and container provisioning à la Docker.
Guix emphasizes programmability and one of its salient features is that it provides a unified Scheme programming environment to deal with with all the aspects of configuration, deployment, and system management-including service management by PID 1. I will illustrate how
this works out on standalone Guix systems, and show the benefits of the approach by discussing applications that take advantage of Guix as a library to support reproducible software deployment.
Last, I will reflect on the road that led to Guix 1.0 six months ago and present some of the challenges ahead.
