In many cases, people want to start containers on a system where the administrator is not happy about granting privileges to users or installing any new software. For example, when I was a researcher and wanted to run Python 3 on a computing cluster it was not possible to get the administrator to install Docker or Python 3.

In recent Linux kernels, it has been possible to create containers without any privileges. All that's missing is a container runtime that allows you to do this. LXC is close but falls short (it requires certain privileged processes and PAM modules for everything to work).

The current state of the work is available here. All of the basics work properly, but there's lots of unresolved things left to deal with (as well as lots of cleanup to be done). In addition, certain tools don't work as expected in a rootless container (such as anything that tries to use the unix privilege model). So, I've started work on a tool to fix that issue as well.

I also would like to write some blog posts about all of this work.

    ADS-B receiver with MicroOS by epaolantonio

    I would like to put one of my spare Raspberry Pis to good use, and what better way to see what flies above my head at any time? add-emoji

    There are various ready-to-use distros already set-up to provide feeder data to platforms like Flightradar24, ADS-B Exchange, FlightAware etc... The goal here would be to do it using MicroOS as a base and containerized decoding of ADS-B data (via tools like dump1090) and web frontend (tar1090).

    Goals

    • Create a working receiver using MicroOS as a base, and containers based on Tumbleweed
    • Make it easy to install
    • Optimize for maximum laziness (i.e. it should take care of itself with minimum intervention)

    Resources

    • 1x Small Board Computer capable of running MicroOS
    • 1x RTL2832U DVB-T dongle
    • 1x MicroSD card
    • https://github.com/antirez/dump1090
    • https://github.com/flightaware/dump1090 (dump1090 fork by FlightAware)
    • https://github.com/wiedehopf/tar1090

    Project status (2024-11-22)

    So I'd say that I'm pretty satisfied with how it turned out. I've packaged readsb (as a replacement for dump1090), tar1090, tar1090-db and mlat-client (not used yet).

    Current status:

    • Able to set-up a working receiver using combustion+ignition (web app based on Fuel Ignition)
    • Able to feed to various feeds using the Beast protocol (Airplanes.live, ADSB.fi, ADSB.lol, ADSBExchange.com, Flyitalyadsb.com, Planespotters.net)
    • Able to feed to Flightradar24 (initial-setup available but NOT tested! I've only tested using a key I already had)
    • Local web interface (tar1090) to easily visualize the results
    • Cockpit pre-configured to ease maintenance

    What's missing:

    • MLAT (Multilateration) support. I've packaged mlat-client already, but I have to wire it up
    • FlightAware support

    Improve Development Environment on Uyuni by mbussolotto

    Description

    Currently create a dev environment on Uyuni might be complicated. The steps are:

    • add the correct repo
    • download packages
    • configure your IDE (checkstyle, format rules, sonarlint....)
    • setup debug environment
    • ...

    The current doc can be improved: some information are hard to be find out, some others are completely missing.

    Dev Container might solve this situation.

    Goals

    Uyuni development in no time:

    • using VSCode:
      • setting.json should contains all settings (for all languages in Uyuni, with all checkstyle rules etc...)
      • dev container should contains all dependencies
      • setup debug environment
    • implement a GitHub Workspace solution
    • re-write documentation

    Lots of pieces are already implemented: we need to connect them in a consistent solution.

    SUSE AI Meets the Game Board by moio

    Use tabletopgames.ai’s open source TAG and PyTAG frameworks to apply Statistical Forward Planning and Deep Reinforcement Learning to two board games of our own design. On an all-green, all-open source, all-AWS stack!
    A chameleon playing chess in a train car, as a metaphor of SUSE AI applied to games


    AI + Board Games

    Board games have long been fertile ground for AI innovation, pushing the boundaries of capabilities such as strategy, adaptability, and real-time decision-making - from Deep Blue's chess mastery to AlphaZero’s domination of Go. Games aren’t just fun: they’re complex, dynamic problems that often mirror real-world challenges, making them interesting from an engineering perspective.

    As avid board gamers, aspiring board game designers, and engineers with careers in open source infrastructure, we’re excited to dive into the latest AI techniques first-hand.

    Our goal is to develop an all-open-source, all-green AWS-based stack powered by some serious hardware to drive our board game experiments forward!


    Project Goals

    1. Set Up the Stack:

      • Install and configure the TAG and PyTAG frameworks on SUSE Linux Enterprise Base Container Images.
      • Integrate with the SUSE AI stack for GPU-accelerated training on AWS.
      • Validate a sample GPU-accelerated PyTAG workload on SUSE AI.
      • Ensure the setup is entirely repeatable with Terraform and configuration scripts, documenting results along the way.
    2. Design and Implement AI Agents:

      • Develop AI agents for the two board games, incorporating Statistical Forward Planning and Deep Reinforcement Learning techniques.
      • Fine-tune model parameters to optimize game-playing performance.
      • Document the advantages and limitations of each technique.
    3. Test, Analyze, and Refine:

      • Conduct AI vs. AI and AI vs. human matches to evaluate agent strategies and performance.
      • Record insights, document learning outcomes, and refine models based on real-world gameplay.

    Technical Stack

    • Frameworks: TAG and PyTAG for AI agent development
    • Platform: SUSE AI
    • Tools: AWS for high-performance GPU acceleration

    Why This Project Matters

    This project not only deepens our understanding of AI techniques by doing but also showcases the power and flexibility of SUSE’s open-source infrastructure for supporting high-level AI projects. By building on an all-open-source stack, we aim to create a pathway for other developers and AI enthusiasts to explore, experiment, and deploy their own innovative projects within the open-source space.


    Our Motivation

    We believe hands-on experimentation is the best teacher.

    Combining our engineering backgrounds with our passion for board games, we’ll explore AI in a way that’s both challenging and creatively rewarding. Our ultimate goal? To hack an AI agent that’s as strategic and adaptable as a real human opponent (if not better!) — and to leverage it to design even better games... for humans to play!


    ClusterOps - Easily install and manage your personal kubernetes cluster by andreabenini

    Description

    ClusterOps is a Kubernetes installer and operator designed to streamline the initial configuration and ongoing maintenance of kubernetes clusters. The focus of this project is primarily on personal or local installations. However, the goal is to expand its use to encompass all installations of Kubernetes for local development purposes.
    It simplifies cluster management by automating tasks and providing just one user-friendly YAML-based configuration config.yml.

    Overview

    • Simplified Configuration: Define your desired cluster state in a simple YAML file, and ClusterOps will handle the rest.
    • Automated Setup: Automates initial cluster configuration, including network settings, storage provisioning, special requirements (for example GPUs) and essential components installation.
    • Ongoing Maintenance: Performs routine maintenance tasks such as upgrades, security updates, and resource monitoring.
    • Extensibility: Easily extend functionality with custom plugins and configurations.
    • Self-Healing: Detects and recovers from common cluster issues, ensuring stability, idempotence and reliability. Same operation can be performed multiple times without changing the result.
    • Discreet: It works only on what it knows, if you are manually configuring parts of your kubernetes and this configuration does not interfere with it you can happily continue to work on several parts and use this tool only for what is needed.

    Features

    • distribution and engine independence. Install your favorite kubernetes engine with your package manager, execute one script and you'll have a complete working environment at your disposal.
    • Basic config approach. One single config.yml file with configuration requirements (add/remove features): human readable, plain and simple. All fancy configs managed automatically (ingress, balancers, services, proxy, ...).
    • Local Builtin ContainerHub. The default installation provides a fully configured ContainerHub available locally along with the kubernetes installation. This configuration allows the user to build, upload and deploy custom container images as they were provided from external sources. Internet public sources are still available but local development can be kept in this localhost server. Builtin ClusterOps operator will be fetched from this ContainerHub registry too.
    • Kubernetes official dashboard installed as a plugin, others planned too (k9s for example).
    • Kubevirt plugin installed and properly configured. Unleash the power of classic virtualization (KVM+QEMU) on top of Kubernetes and manage your entire system from there, libvirtd and virsh libs are required.
    • One operator to rule them all. The installation script configures your machine automatically during installation and adds one kubernetes operator to manage your local cluster. From there the operator takes care of the cluster on your behalf.
    • Clean installation and removal. Just test it, when you are done just use the same program to uninstall everything without leaving configs (or pods) behind.

    Planned features (Wishlist / TODOs)

    • Containerized Data Importer (CDI). Persistent storage management add-on for Kubernetes to provide a declarative way of building and importing Virtual Machine Disks on PVCs for


    Migrate from Docker to Podman by tjyrinki_suse

    Description

    I'd like to continue my former work on containerization of several domains on a single server by changing from Docker containers to Podman containers. That will need an OS upgrade as well as Podman is not available in that old server version.

    Goals

    • Update OS.
    • Migrate from Docker to Podman.
    • Keep everything functional, including the existing "meanwhile done" additional Docker container that is actually being used already.
    • Keep everything at least as secure as currently. One of the reasons of having the containers is to isolate risks related to services open to public Internet.
    • Try to enable the Podman use in production.
    • At minimum, learn about all of these topics.
    • Optionally, improve Ansible side of things as well...
