Planet Guix

How do you use Guix on HPC when your friendly HPC admins are uncooperative? This is the ultimate solution.

Today I’m excited to announce the launch of the new System Crafters Forum!

This post is about using Guix for the provisioning and management of cloud machines and services. Beyond the official documentation, there are various great tutorials around this topic already, like this one, this one, or this other one. I'm writing this up primarily as a note-to-self, and in case my specific approach can be of interest to anyone else.

Dealing with secrets in functional operating systems can range from pretty usable to complete hell. Nix has several answers to this problem, the more integrated of which appears to be sops-nix. After spending some months envying our neighbors grass, I figured it was time for Guix to have its own (attempt at an) answer to the secrets problem.

If you need to run Grafana on the Guix System this post is the right place. In this example we'll setup Grafana to read metrics from the same machine it's run upon, but you can adapt this to use a remote datasource.

This is the outline of a short session on Guix that I had the chance to organise at the 37th Chaos Communication Congress, or 37c3, in December 2023. It's not worth much, but I thought it was useful to have it here in case I want to reuse it or refer to it in the future.

Many applications are packaged in OCI/Docker images but not in Guix. A good subset of them is written either in NodeJS, Go, Rust or languages that, as a general approach, encourage applications to have huge dependency graphs.
