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

1. Find and track the issue with google/nftables
2. Revisit and polish the Go or Python code (prefer Go, but possibly depends on implementing missing functionality), primarily the server component
3. Finish functionality to interact with nftables sets (retrieving and updating elements), which are of interest for the originating issue
4. Align test suite
5. 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

• Started new https://github.com/tacerus/nftables-http-api.
• First Go nftables issue was related to set elements needing to be added with different start and end addresses - coincidentally, this was recently discovered by someone else, who added a useful helper function for this: https://github.com/google/nftables/pull/342.
• Further improvements submitted: https://github.com/google/nftables/pull/347.

Side results

Upon starting to unify the structure and implementing more functionality, missing JSON output support was noticed for some subcommands in libnftables. Submitted patches here as well:

Contribute to terraform-provider-libvirt by pinvernizzi

Description

The SUSE Manager (SUMA) teams' main tool for infrastructure automation, Sumaform, largely relies on terraform-provider-libvirt. That provider is also widely used by other teams, both inside and outside SUSE.

It would be good to help the maintainers of this project and give back to the community around it, after all the amazing work that has been already done.

If you're interested in any of infrastructure automation, Terraform, virtualization, tooling development, Go (...) it is also a good chance to learn a bit about them all by putting your hands on an interesting, real-use-case and complex project.

Goals

• Get more familiar with Terraform provider development and libvirt bindings in Go
• Solve some issues and/or implement some features
• Get in touch with the community around the project

Resources

• CONTRIBUTING readme
• Go libvirt library in use by the project
• Terraform plugin development

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

go-git: unlocking SHA256-based repository cloning ahead of git v3 by pgomes

Description

The go-git library implements the git internals in pure Go, so that any Go application can handle not only Git repositories, but also lower-level primitives (e.g. packfiles, idxfiles, etc) without needing to shell out to the git binary.

The focus for this Hackweek is to fast track key improvements for the project ahead of the upstream release of Git V3, which may take place at some point next year.

Goals

• Add support for cloning SHA256 repositories.
• Decrease memory churn for very large repositories (e.g. Linux Kernel repository).
• Cut the first alpha version for go-git/v6.

Stretch goals

• Review and update the official documentation.
• Optimise use of go-git in Fleet.
• Create RFC/example for go-git plugins to improve extensibility.
• Investigate performance bottlenecks for Blame and Status.

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

Sim racing track database by avicenzi

Description

Do you wonder which tracks are available in each sim racing game? Wonder no more.

Goals

Create a simple website that includes details about sim racing games.

The website should be static and built with Alpine.JS and TailwindCSS. Data should be consumed from JSON, easily done with Alpine.JS.

The main goal is to gather track information, because tracks vary by game. Older games might have older layouts, and newer games might have up-to-date layouts. Some games include historical layouts, some are laser scanned. Many tracks are available as DLCs.

Initially include official tracks from:

• ACC
• iRacing
• PC2
• LMU
• Raceroom
• Rennsport

These games have a short list of tracks and DLCs.

Resources

The hardest part is collecting information about tracks in each game. Active games usually have information on their website or even on Steam. Older games might be on Fandom or a Wiki. Real track information can be extracted from Wikipedia or the track website.

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
• Go code improvement

What you might learn

Harvester CLI might be interesting to you if you want to learn more about:

• GitHub Actions
• Harvester as a SUSE Product
• Go programming language
• Kubernetes API
• Kubevirt API objects (Manipulating VMs and VM Configuration in Kubernetes using Kubevirt)
