    Introducing "Bottles": A Proof of Concept for Multi-Version CRD Management in Kubernetes by aruiz

    Description

    As we delve deeper into the complexities of managing multiple CRD versions within a single Kubernetes cluster, I want to introduce "Bottles" - a proof of concept that aims to address these challenges.

    Bottles propose a novel approach to isolating and deploying different CRD versions in a self-contained environment. This would allow for greater flexibility and efficiency in managing diverse workloads.

    Goals

    • Evaluate Feasibility: determine if this approach is technically viable, as well as identifying possible obstacles and limitations.
    • Reuse existing technology: leverage existing products whenever possible, e.g. build on top of Kubewarden as admission controller.
    • Focus on Rancher's use case: the ultimate goal is to be able to use this approach to solve Rancher users' needs.

    Resources

    Core concepts:

    • ConfigMaps: Bottles could be defined and configured using ConfigMaps.
    • Admission Controller: An admission controller will detect "bootled" CRDs being installed and replace the resource name used to store them.
    • Aggregated API Server: By analyzing the author of a request, the aggregated API server will determine the correct bottle and route the request accordingly, making it transparent for the user.

    Integrate Backstage with Rancher Manager by nwmacd

    Description

    Backstage (backstage.io) is an open-source, CNCF project that allows you to create your own developer portal. There are many plugins for Backstage.

    This could be a great compliment to Rancher Manager.

    Goals

    Learn and experiment with Backstage and look at how this could be integrated with Rancher Manager. Goal is to have some kind of integration completed in this Hack week.

    Progress

    Screen shot of home page at the end of Hackweek:

    Home

    Day One

    • Got Backstage running locally, understanding configuration with HTTPs.
    • Got Backstage embedded in an IFRAME inside of Rancher
    • Added content into the software catalog (see: https://backstage.io/docs/features/techdocs/getting-started/)
    • Understood more about the entity model

    Day Two

    • Connected Backstage to the Rancher local cluster and configured the Kubernetes plugin.
    • Created Rancher theme to make the light theme more consistent with Rancher

    Home

    Days Three and Day Four

    • Created two backend plugins for Backstage:

      1. Catalog Entity Provider - this imports users from Rancher into Backstage
      2. Auth Provider - uses the proxied sign-in pattern to check the Rancher session cookie, to user that to authenticate the user with Rancher and then log them into Backstage by connecting this to the imported User entity from the catalog entity provider plugin.
    • With this in place, you can single-sign-on between Rancher and Backstage when it is deployed within Rancher. Note this is only when running locally for development at present

    Home

    Home

    Day Five

    • Start to build out a production deployment for all of the above
    • Made some progress, but hit issues with the authentication and proxying when running proxied within Rancher, which needs further investigation


    Small healthcheck tool for Longhorn by mbrookhuis

    Project Description

    We have often problems (e.g. pods not starting) that are related to PVCs not running, cluster (nodes) not all up or deployments not running or completely running. This all prevents administration activities. Having something that can regular be run to validate the status of the cluster would be helpful, and not as of today do a lot of manual tasks.

    As addition (read enough time), we could add changing reservation, adding new disks, etc. --> This didn't made it. But the scripts can easily be adopted.

    This tool would decrease troubleshooting time, giving admins rights to the rancher GUI and could be used in automation.

    Goal for this Hackweek

    At the end we should have a small python tool that is doing a (very) basic health check on nodes, deployments and PVCs. First attempt was to make it in golang, but that was taking to much time.

    Overview

    This tool will run a simple healthcheck on a kubernetes cluster. It will perform the following actions:

    • node check: This will check all nodes, and display the status and the k3s version. If the status of the nodes is not "Ready" (this should be only reported), the cluster will be reported as having problems

    • deployment check: This check will list all deployments, and display the number of expected replicas and the used replica. If there are unused replicas this will be displayed. The cluster will be reported as having problems.

    • pvc check: This check will list of all pvc's, and display the status and the robustness. If the robustness is not "Healthy", the cluster will be reported as having problems.

    If there is a problem registered in the checks, there will be a warning that the cluster is not healthy and the program will exit with 1.

    The script has 1 mandatory parameter and that is the kubeconf of the cluster or of a node off the cluster.

    The code is writen for Python 3.11, but will also work on 3.6 (the default with SLES15.x). There is a venv present that will contain all needed packages. Also, the script can be run on the cluster itself or any other linux server.

    Installation

    To install this project, perform the following steps:

    • Create the directory /opt/k8s-check

    mkdir /opt/k8s-check

    • Copy all the file to this directory and make the following changes:

    chmod +x k8s-check.py


    Harvester Packer Plugin by mrohrich

    Description

    Hashicorp Packer is an automation tool that allows automatic customized VM image builds - assuming the user has a virtualization tool at their disposal. To make use of Harvester as such a virtualization tool a plugin for Packer needs to be written. With this plugin users could make use of their Harvester cluster to build customized VM images, something they likely want to do if they have a Harvester cluster.

    Goals

    Write a Packer plugin bridging the gap between Harvester and Packer. Users should be able to create customized VM images using Packer and Harvester with no need to utilize another virtualization platform.

    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).

FamilyTrip Planner not only simplifies the travel planning process but also offers a comprehensive, personalized experience for families.

    Goals

    This project aims to: - Create a user-friendly platform that assists families in planning complete trips, from flight and accommodation options to recommended family-friendly activities. - Provide intelligent, personalized travel itineraries using artificial intelligence to enhance travel enjoyment and minimize time and cost. - Serve as an educational project for exploring Go programming and artificial intelligence, with the goal of building proficiency in both.

    Resources

    To develop FamilyTrip Planner, the project will leverage: - APIs such as Skyscanner, Google Places, and TripAdvisor to source real-time information on flights, accommodations, and activities. - Go programming language to manage data integration, API connections, and backend development. - Basic machine learning libraries to implement AI-driven itinerary suggestions tailored to family needs and preferences.


    WebUI for your data by avicenzi

    A single place to view every bit of data you have.

    Problem

    You have too much data and you are a data hoarder.

    • Family photos and videos.
    • Lots of eBooks, TV Shows, Movies, and else.
    • Boxes full of papers (taxes, invoices, IDs, certificates, exams, and else).
    • Bank account statements (multiple currencies, countries, and people).

    Maybe you have some data on S3, some on your NAS, and some on your local PC.

    • How do you get it all together?
    • How do you link a bank transaction to a product invoice?
    • How to tag any object type and create a collection out of it (mix videos, photos, PDFs, transactions)?
    • How to store this? file/folder structure does not work, everything is linked together

    Project Description

    The idea is a place where you can throw all your data, photos, videos, documents, binaries, and else.

    Create photo albums, document collections, add tags across multiple file-formats, link content, and else.

    The UI should be easy to use, where the data is not important for now (could be all S3 or local drive).

    Similar proposals

    The closest I found so far is https://perkeep.org/, but this is not what I'm looking for.

    Goal for this Hackweek

    Create a web UI, in Svelte ideally, perhaps React.

    It should be able to show photos and videos at least.

    Resources

    None so far, this is just an idea.


    A CLI for Harvester by mohamed.belgaied

    [comment]: # Harvester does not officially come with a CLI tool, the user is supposed to interact with Harvester mostly through the UI [comment]: # Though it is theoretically possible to use kubectl to interact with Harvester, the manipulation of Kubevirt YAML objects is absolutely not user friendly. [comment]: # 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
