Updated over 4 years ago. 3 hacker ♥️. 1 follower.

Project Description

I want for long time to get my hands dirty with go and webassembly. we have (openqa-mon)[https://github.com/grisu48/openqa-mon] which is a monitoring tool for OpenQA. The aiming is to learn a bit more about those tools and convert the project in webassembly

Goal for this Hackweek

  • Make openqa-mon a webapp

During the process i believe i can also:

  • identify future features
  • Make documentation
  • write some tests for openqa-mon(??)

      So the results were not the expected but i guess i learned a few things during this. briefly, the implementation of openqa-mon uses syscall library. this alone was enough to block the idea as it will require significant changes to get accomplished. Particularly, the dependency on Tui.go should be altered or removed. The submodule syscall/js provides some access to the WebAssembly host environment when using the js/wasm architecture. The attempt to use this ended with massive changes either to tui.go or/and openqa-mon.go. With those changes in place and a bit of javascript, an openqa-mon in webassembly project is possible. While thinking how to solve the problem above i found the "browsix"[0]. Another webassmbly app to run console on the browser written in Go. I thought to try out this and call the openqa-mon as utility of the browsix shell. this also failed due to some packages' dependencies during the build.

      What actually i had accomplished during this hackweek was - to find and fix a bug on openqa-mon. - Add a single test for the fix - Learn some things about webassembly and go, and refresh some javascript - Create the additional files to launch the openqa-mon.wasm (server.go and openqa-mon_web.wasm)

    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

    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.

    asciicast

    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)

    Play with the userfaultfd(2) system call and download on demand using HTTP Range Requests with Golang by rbranco

    Description

    The userfaultfd(2) is a cool system call to handle page faults in user-space. This should allow me to list the contents of an ISO or similar archive without downloading the whole thing. The userfaultfd(2) part can also be done in theory with the PROT_NONE mprotect + SIGSEGV trick, for complete Unix portability, though reportedly being slower.

    Goals

    1. Create my own library for userfaultfd(2) in Golang.
    2. Create my own library for HTTP Range Requests.
    3. Complete portability with Unix.
    4. Benchmarks.
    5. Contribute some tests to LTP.

    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

    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.

    Kudos aka openSUSE Recognition Platform by lkocman

    Description

    Relevant blog post at news-o-o

    I started the Kudos application shortly after Leap 16.0 to create a simple, friendly way to recognize people for their work and contributions to openSUSE. There’s so much more to our community than just submitting requests in OBS or gitea we have translations (not only in Weblate), wiki edits, forum and social media moderation, infrastructure maintenance, booth participation, talks, manual testing, openQA test suites, and more!

    Goals

    • Kudos under github.com/openSUSE/kudos with build previews aka netlify

    • Have a kudos.opensuse.org instance running in production

    • Build an easy-to-contribute recognition platform for the openSUSE community a place where everyone can send and receive appreciation for their work, across all areas of contribution.

    • In the future, we could even explore reward options such as vouchers for t-shirts or other community swag, small tokens of appreciation to make recognition more tangible.
