Project Description

Go (or Golang) is an open-source programming language designed to build fast, reliable, and efficient software at scale. It is the language used to create Kubernetes, K3s, Rancher, and countless cloud-native applications. Let's learn Go by writing an application during the hack week!

Goal for this Hackweek

Understand the syntax and grammars of Go
Learn the advanced features of Go
Get familiar with Go’s standard libraries/packages
Write an application following this tutorial

Resources

There are tons of tutorials and articles on the internet, but not all of them are of high quality or up-to-date. If you know any article/book/tutorial that is good for a beginner, please do not hesitate to share them in the comments.

Here are some resources I will use to learn Go:

Q2Boot - A handy QEMU VM launcher by amanzini

Description

Q2Boot (Qemu Quick Boot) is a command-line tool that wraps QEMU to provide a streamlined experience for launching virtual machines. It automatically configures common settings like KVM acceleration, virtio drivers, and networking while allowing customization through both configuration files and command-line options.

The project originally was a personal utility in D, now recently rewritten in idiomatic Go. It lives at repository https://github.com/ilmanzo/q2boot

Goals

Improve the project, testing with different scenarios , address issues and propose new features. It will benefit of some basic integration testing by providing small sample disk images.

Updates

Dec 1, 2025 : refactor command line options, added structured logging. Released v0.0.2

Create a Cloud-Native policy engine with notifying capabilities to optimize resource usage by gbazzotti

Description

The goal of this project is to begin the initial phase of development of an all-in-one Cloud-Native Policy Engine that notifies resource owners when their resources infringe predetermined policies. This was inspired by a current issue in the CES-SRE Team where other solutions seemed to not exactly correspond to the needs of the specific workloads running on the Public Cloud Team space.

The initial architecture can be checked out on the Repository listed under Resources.

Among the features that will differ this project from other monitoring/notification systems:

Pre-defined sensible policies written at the software-level, avoiding a learning curve by requiring users to write their own policies
All-in-one functionality: logging, mailing and all other actions are not required to install any additional plugins/packages
Easy account management, being able to parse all required configuration by a single JSON file
Eliminate integrations by not requiring metrics to go through a data-agreggator

Goals

Create a minimal working prototype following the workflow specified on the documentation
Provide instructions on installation/usage
Work on email notifying capabilities

Updatecli Autodiscovery supporting WASM plugins by olblak

Description

Updatecli is a Golang Update policy engine that allow to write Update policies in YAML manifest. Updatecli already has a plugin ecosystem for common update strategies such as automating Dockerfile or Kubernetes manifest from Git repositories.

This is what we call autodiscovery where Updatecli generate manifest and apply them dynamically based on some context.

Obviously, the Updatecli project doesn't accept plugins specific to an organization.

I saw project using different languages such as python, C#, or JS to generate those manifest.

It would be great to be able to share and reuse those specific plugins

During the HackWeek, I'll hang on the Updatecli matrix channel

https://matrix.to/#/#Updatecli_community:gitter.im

Goals

Implement autodiscovery plugins using WASM. I am planning to experiment with https://github.com/extism/extism

To build a simple WASM autodiscovery plugin and run it from Updatecli

terraform-provider-feilong by e_bischoff

Project Description

People need to test operating systems and applications on s390 platform.

Installation from scratch solutions include:

just deploy and provision manually (with the help of ftpboot script, if you are at SUSE)
use s3270 terminal emulation (used by openQA people?)
use LXC from IBM to start CP commands and analyze the results
use zPXE to do some PXE-alike booting (used by the orthos team?)
use tessia to install from scratch using autoyast
use libvirt for s390 to do some nested virtualization on some already deployed z/VM system
directly install a Linux kernel on a LPAR and use kvm + libvirt from there

Deployment from image solutions include:

use ICIC web interface (openstack in disguise, contributed by IBM)
use ICIC from the openstack terraform provider (used by Rancher QA)
use zvm_ansible to control SMAPI
connect directly to SMAPI low-level socket interface

IBM Cloud Infrastructure Center (ICIC) harnesses the Feilong API, but you can use Feilong without installing ICIC, provided you set up a "z/VM cloud connector" into one of your VMs following this schema.

What about writing a terraform Feilong provider, just like we have the terraform libvirt provider? That would allow to transparently call Feilong from your main.tf files to deploy and destroy resources on your system/z.

Goal for Hackweek 23

My final goal is to be able to easily deploy and provision VMs automatically on a z/VM system, in a way that people might enjoy even outside of SUSE.

My technical preference is to write a terraform provider plugin, as it is the approach that involves the least software components for our deployments, while remaining clean, and compatible with our existing development infrastructure.

Goals for Hackweek 24

Feilong provider works and is used internally by SUSE Manager team. Let's push it forward!

Let's add support for fiberchannel disks and multipath.

Goals for Hackweek 25

Help Create A Chat Control Resistant Turnkey Chatmail/Deltachat Relay Stack - Rootless Podman Compose, OpenSUSE BCI, Hardened, & SELinux by 3nd5h1771fy

Description

The Mission: Decentralized & Sovereign Messaging

FYI: If you have never heard of "Chatmail", you can visit their site here, but simply put it can be thought of as the underlying protocol/platform decentralized messengers like DeltaChat use for their communications. Do not confuse it with the honeypot looking non-opensource paid for prodect with better seo that directs you to chatmailsecure(dot)com

In an era of increasing centralized surveillance by unaccountable bad actors (aka BigTech), "Chat Control," and the erosion of digital privacy, the need for sovereign communication infrastructure is critical. Chatmail is a pioneering initiative that bridges the gap between classic email and modern instant messaging, offering metadata-minimized, end-to-end encrypted (E2EE) communication that is interoperable and open.

However, unless you are a seasoned sysadmin, the current recommended deployment method of a Chatmail relay is rigid, fragile, difficult to properly secure, and effectively takes over the entire host the "relay" is deployed on.

Why This Matters

A simple, host agnostic, reproducible deployment lowers the entry cost for anyone wanting to run a privacy‑preserving, decentralized messaging relay. In an era of perpetually resurrected chat‑control legislation threats, EU digital‑sovereignty drives, and many dangers of using big‑tech messaging platforms (Apple iMessage, WhatsApp, FB Messenger, Instagram, SMS, Google Messages, etc...) for any type of communication, providing an easy‑to‑use alternative empowers:

Censorship resistance - No single entity controls the relay; operators can spin up new nodes quickly.
Surveillance mitigation - End‑to‑end OpenPGP encryption ensures relay operators never see plaintext.
Digital sovereignty - Communities can host their own infrastructure under local jurisdiction, aligning with national data‑policy goals.

By turning the Chatmail relay into a plug‑and‑play container stack, we enable broader adoption, foster a resilient messaging fabric, and give developers, activists, and hobbyists a concrete tool to defend privacy online.

Goals

As I indicated earlier, this project aims to drastically simplify the deployment of Chatmail relay. By converting this architecture into a portable, containerized stack using Podman and OpenSUSE base container images, we can allow anyone to deploy their own censorship-resistant, privacy-preserving communications node in minutes.

Our goal for Hack Week: package every component into containers built on openSUSE/MicroOS base images, initially orchestrated with a single container-compose.yml (podman-compose compatible). The stack will:

Run on any host that supports Podman (including optimizations and enhancements for SELinux‑enabled systems).
Allow network decoupling by refactoring configurations to move from file-system constrained Unix sockets to internal TCP networking, allowing containers achieve stricter isolation.
Utilize Enhanced Security with SELinux by using purpose built utilities such as udica we can quickly generate custom SELinux policies for the container stack, ensuring strict confinement superior to standard/typical Docker deployments.
Allow the use of bind or remote mounted volumes for shared data (/var/vmail, DKIM keys, TLS certs, etc.).
Replace the local DNS server requirement with a remote DNS‑provider API for DKIM/TXT record publishing.

By delivering a turnkey, host agnostic, reproducible deployment, we lower the barrier for individuals and small communities to launch their own chatmail relays, fostering a decentralized, censorship‑resistant messaging ecosystem that can serve DeltaChat users and/or future services adopting this protocol

A CLI for Harvester by mohamed.belgaied

Harvester does not officially come with a CLI tool, the user is supposed to interact with Harvester mostly through the UI. Though it is theoretically possible to use kubectl to interact with Harvester, the manipulation of Kubevirt YAML objects is absolutely not user friendly. Inspired by tools like multipass from Canonical to easily and rapidly create one of multiple VMs, I began the development of Harvester CLI. Currently, it works but Harvester CLI needs some love to be up-to-date with Harvester v1.0.2 and needs some bug fixes and improvements as well.

Project Description

Harvester CLI is a command line interface tool written in Go, designed to simplify interfacing with a Harvester cluster as a user. It is especially useful for testing purposes as you can easily and rapidly create VMs in Harvester by providing a simple command such as: harvester vm create my-vm --count 5 to create 5 VMs named my-vm-01 to my-vm-05.

Harvester CLI is functional but needs a number of improvements: up-to-date functionality with Harvester v1.0.2 (some minor issues right now), modifying the default behaviour to create an opensuse VM instead of an ubuntu VM, solve some bugs, etc.

Github Repo for Harvester CLI: https://github.com/belgaied2/harvester-cli

Done in previous Hackweeks

Create a Github actions pipeline to automatically integrate Harvester CLI to Homebrew repositories: DONE
Automatically package Harvester CLI for OpenSUSE / Redhat RPMs or DEBs: DONE

Goal for this Hackweek

The goal for this Hackweek is to bring Harvester CLI up-to-speed with latest Harvester versions (v1.3.X and v1.4.X), and improve the code quality as well as implement some simple features and bug fixes.

Some nice additions might be: * Improve handling of namespaced objects * Add features, such as network management or Load Balancer creation ? * Add more unit tests and, why not, e2e tests * Improve CI * Improve the overall code quality * Test the program and create issues for it

Issue list is here: https://github.com/belgaied2/harvester-cli/issues

Resources

The project is written in Go, and using client-go the Kubernetes Go Client libraries to communicate with the Harvester API (which is Kubernetes in fact). Welcome contributions are:

Testing it and creating issues
Documentation

HTTP API for nftables by crameleon

Background

The idea originated in https://progress.opensuse.org/issues/164060 and is about building RESTful API which translates authorized HTTP requests to operations in nftables, possibly utilizing libnftables-json(5).

Originally, I started developing such an interface in Go, utilizing https://github.com/google/nftables. The conversion of string networks to nftables set elements was problematic (unfortunately no record of details), and I started a second attempt in Python, which made interaction much simpler thanks to native nftables Python bindings.

Goals

Find and track the issue with google/nftables
Revisit and polish the Python code, primarily the server component
Finish functionality to interact with nftables sets (retrieving and updating elements), which are of interest for the originating issue
Align test suite
Packaging

Resources

https://git.netfilter.org/nftables/tree/py/src/nftables.py
https://git.com.de/Georg/nftables-http-api (to be moved to GitHub)
https://build.opensuse.org/package/show/home:crameleon:containers/pytest-nftables-container

Results

The original goals will probably not be met, but progress is made regardless. Upon starting to unify the structure and implementing more functionality, missing JSON output support was noticed for some subcommands in libnftables. I am submitting patches as needed: - https://lore.kernel.org/netfilter-devel/20251203131736.4036382-2-georg@syscid.com/T/#u

Add support for todo.sr.ht to git-bug by mcepl

Description

I am a big fan of distributed issue tracking and the best (and possibly) only credible such issue tracker is now git-bug. It has bridges to another centralized issue trackers, so user can download (and modify) issues on GitHub, GitLab, Launchpad, Jira). I am also a fan of SourceHut, which has its own issue tracker, so I would like it bridge the two. Alas, I don’t know much about Go programming language (which the git-bug is written) and absolutely nothing about GraphQL (which todo.sr.ht uses for communication). AI to the rescue. I would like to vibe code (and eventually debug and make functional) bridge to the SourceHut issue tracker.

Goals

Functional fix for https://github.com/git-bug/git-bug/issues/1024

Resources

anybody how actually understands how GraphQL and authentication on SourceHut (OAuth2) works

Create a go module to wrap happy-compta.fr by cbosdonnat

Description

https://happy-compta.fr is a tool for french work councils simple book keeping. While it does the job, it has no API to work with and it is tedious to enter loads of operations.

Goals

Write a go client module to be used as an API to programmatically manipulate the tool.

Writing an example tool to load data from a CSV file would be good too.

Kubernetes-Based ML Lifecycle Automation by lmiranda

Description

This project aims to build a complete end-to-end Machine Learning pipeline running entirely on Kubernetes, using Go, and containerized ML components.

The pipeline will automate the lifecycle of a machine learning model, including:

Data ingestion/collection
Model training as a Kubernetes Job
Model artifact storage in an S3-compatible registry (e.g. Minio)
A Go-based deployment controller that automatically deploys new model versions to Kubernetes using Rancher
A lightweight inference service that loads and serves the latest model
Monitoring of model performance and service health through Prometheus/Grafana

The outcome is a working prototype of an MLOps workflow that demonstrates how AI workloads can be trained, versioned, deployed, and monitored using the Kubernetes ecosystem.

Goals

By the end of Hack Week, the project should:

Produce a fully functional ML pipeline running on Kubernetes with:
- Data collection job
- Training job container
- Storage and versioning of trained models
- Automated deployment of new model versions
- Model inference API service
- Basic monitoring dashboards
Showcase a Go-based deployment automation component, which scans the model registry and automatically generates & applies Kubernetes manifests for new model versions.
Enable continuous improvement by making the system modular and extensible (e.g., additional models, metrics, autoscaling, or drift detection can be added later).
Prepare a short demo explaining the end-to-end process and how new models flow through the system.

Advent of Code: The Diaries by amanzini

Description

It was the Night Before Compile Time ...

Hackweek 25 (December 1-5) perfectly coincides with the first five days of Advent of Code 2025. This project will leverage this overlap to participate in the event in real-time.

To add a layer of challenge and exploration (in the true spirit of Hackweek), the puzzles will be solved using a non-mainstream, modern language like Ruby, D, Crystal, Gleam or Zig.

The primary project intent is not just simply to solve the puzzles, but to exercise result sharing and documentation. I'd create a public-facing repository documenting the process. This involves treating each day's puzzle as a mini-project: solving it, then documenting the solution with detailed write-ups, analysis of the language's performance and ergonomics, and visualizations.

toki pona programing language by dgarcia

Description

Toki Pona is a philosophical and artistic constructed language designed for its small vocabulary, simplicity, and ease of acquisition.

The idea is to bring the idea of simplicity to a new programing language using this language words and limitations to implement it.

The name for this programming language could be: "toki ilo" or "ilo pona". I will ask the community to get other ideas and also to get feedback about the initial design.

The idea is to start to implement something as a gcc frontend.

Goals

The language design should be really simple but completely functional:
- functions
- variables
- conditional
- loop
- data structures
The keywords should be from toki pona, and better if could be read as pseudo code in toki pona
It should be possible to "compile" code written in sitelen pona
