Project Description

grog aims to implements a namespaced, distributed map kept alive by an arbitrary number of nodes over a local network.
It uses TCP and UDP multicast.

For a detailed specification see grog's github repository

grog can be implemented in any programming language.
It deals with networking problems in a distributed cluster.

  • Possibly useful when developing a distributed application.
  • Not designed to be used in production.
  • Not meant to be efficient in space.
  • Immediate usage.
  • Zero network configuration.
  • No data definition.
  • Arbitrary complex type for values.
  • json as unique value's format.
  • Small operation set to access and manipulate the map:
    • get, to get the value of a key from a map
    • set, to add or update the value of a key in a map
    • del, to remove a key, value pair from a map
  • Integrable in programs where an implementation for that language exists.

Goal for this Hackweek

Play with Go programming language.
Try to provide a minimum viable deamon and CLI written in Go.

    ddflare: (Dynamic)DNS management via Cloudflare API in Kubernetes by fgiudici

    Description

    ddflare is a project started a couple of weeks ago to provide DDNS management using v4 Cloudflare APIs: Cloudflare offers management via APIs and access tokens, so it is possible to register a domain and implement a DynDNS client without any other external service but their API.

    Since ddflare allows to set any IP to any domain name, one could manage multiple A and ALIAS domain records. Wouldn't be cool to allow full DNS control from the project and integrate it with your Kubernetes cluster?

    Goals

    Main goals are:

    1. add containerized image for ddflare
    2. extend ddflare to be able to add and remove DNS records (and not just update existing ones)
    3. add documentation, covering also a sample pod deployment for Kubernetes
    4. write a ddflare Kubernetes operator to enable domain management via Kubernetes resources (using kubebuilder)

    Available tasks and improvements tracked on ddflare github.

    Cluster API Add-on Provider for Kubewarden by csalas

    Description

    Can we integrate Kubewarden with Cluster API provisioning?

    Cluster API is a Kubernetes project focused on providing declarative APIs and tooling to simplify provisioning, upgrading, and operating multiple Kubernetes clusters. TLDR; CAPI let's you define Kubernetes clusters in plain YAML, and CAPI providers (infrastructure, control plane/bootstrap, etc.) manage provisioning and configuration for you.

    What if we could create an add-on provider that automatically installs Kubewarden and deploys Policy Servers to CAPI clusters?

    Goals

    • As a user I'd like to set a cluster (or list of clusters) and have the provider install Kubewarden for me.
    • As a user I'd like to set what policies must be enforced for a cluster (or list of clusters).

    Jenny Static Site Generator by adam.pickering

    Description

    For my personal site I have been using hugo. It works, but I am not satisfied: every time I want to make a change (which is infrequently) I have to read through the documentation again to understand how hugo works. I don't find the documentation easy to use, and the structure of the repository that hugo requires is unintuitive/more complex than what I need. So, I have decided to write my own simple static site generator in Go. It is named Jenny, after my wife.

    Goals

    • Pages can be written in markdown (which is automatically converted to HTML), but other file types are also allowed
    • Easy to understand and use
      • Intuitive, simple design
      • Clear documentation
      • Hot reloading
      • Binaries provided for download
    • Future maintenance is easy
      • Automated releases

    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

    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

    Add a machine-readable output to dmidecode by jdelvare

    Description

    There have been repeated requests for a machine-friendly dmidecode output over the last decade. During Hack Week 19, 5 years ago, I prepared the code to support alternative output formats, but didn't have the time to go further. Last year, Jiri Hnidek from Red Hat Linux posted a proof-of-concept implementation to add JSON output support. This is a fairly large pull request which needs to be carefully reviewed and tested.

    Goals

    Review Jiri's work and provide constructive feedback. Merge the code if acceptable. Evaluate the costs and benefits of using a library such as json-c.
