[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

    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.

    Resources

    Cluster API Provider for Harvester by rcase

    Project Description

    The Cluster API "infrastructure provider" for Harvester, also named CAPHV, makes it possible to use Harvester with Cluster API. This enables people and organisations to create Kubernetes clusters running on VMs created by Harvester using a declarative spec.

    The project has been bootstrapped in HackWeek 23, and its code is available here.

    Work done in HackWeek 2023

    • Have a early working version of the provider available on Rancher Sandbox : *DONE *
    • Demonstrated the created cluster can be imported using Rancher Turtles: DONE
    • Stretch goal - demonstrate using the new provider with CAPRKE2: DONE and the templates are available on the repo

    Goals for HackWeek 2024

    • Add support for ClusterClass
    • Add e2e testing
    • Add more Unit Tests
    • Improve Status Conditions to reflect current state of Infrastructure
    • Improve CI (some bugs for release creation)
    • Testing with newer Harvester version (v1.3.X and v1.4.X)
    • Due to the length and complexity of the templates, maybe package some of them as Helm Charts.
    • Other improvement suggestions are welcome!

    DONE in HackWeek 24:

    Thanks to @isim and Dominic Giebert for their contributions!

    Harvester Optimization by jyu

    Description

    There are many areas for optimization in Harvester, including build time, testing structure, clear guidelines for beginners, etc.

    For example, I found that out Harvester documentation lacks a validation which checks our links is broken or not. It's annoying to check every links by eyes. Another one is testing time, Harvester doesn't utilize the parallel concept to run test cases.

    So, I'll focus on documentation improvement and speeding up the testing time in this project.

    Goals

    • Parallel testing (ongoing PR https://github.com/harvester/harvester/pull/6223)
    • Documentation link checker
    • A guidelines for beginners of developers (if time permits)

    Extending KubeVirtBMC's capability by adding Redfish support by zchang

    Description

    In Hack Week 23, we delivered a project called KubeBMC (renamed to KubeVirtBMC now), which brings the good old-fashioned IPMI ways to manage virtual machines running on KubeVirt-powered clusters. This opens the possibility of integrating existing bare-metal provisioning solutions like Tinkerbell with virtualized environments. We even received an inquiry about transferring the project to the KubeVirt organization. So, a proposal was filed, which was accepted by the KubeVirt community, and the project was renamed after that. We have many tasks on our to-do list. Some of them are administrative tasks; some are feature-related. One of the most requested features is Redfish support.

    Goals

    Extend the capability of KubeVirtBMC by adding Redfish support. Currently, the virtbmc component only exposes IPMI endpoints. We need to implement another simulator to expose Redfish endpoints, as we did with the IPMI module. We aim at a basic set of functionalities:

    • Power management
    • Boot device selection
    • Virtual media mount (this one is not so basic add-emoji )

    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.


    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)

    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

    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).

    Dartboard TUI by IValentin

    Description

    Our scalability and performance testing swiss-army knife tool Dartboard is a major WIP so why not add more scope creep? Dartboard is a cli tool which enables users to:

    • Define a "Dart" config file as YAML which defines the various components to be created/setup when Dartboard runs its commands
    • Spin up infrastructure utilizing opentofu/terraform providers
    • Setup K3s or RKE2 clusters on the newly created infrastructure
    • Deploy Rancher (with or without downstream cluster), rancher-monitoring (Grafana + Prometheus)
    • Create resources in-bulk within the newly created Rancher cluster (ConfigMaps, Secrets, Users, Roles, etc.)
    • Run various performance and scalability tests via k6
    • Export/Import various tracked metrics (WIP)

    Given all these features (and the features to come), it can be difficult to onboard and transfer knowledge of the tool. With a TUI, Dartboard's usage complexity can be greatly reduced!

    Goals

    • Create a TUI for Dartboard's "subcommands"
    • Gain more familiarity with Dartboard and create a more user-friendly interface to enable others to use it
    • Stretch Create a TUI workflow for generating a Dart file

    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.


    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.

    suse-rancher-supportconfig by eminguez

    Description

    Update: Live at https://github.com/e-minguez/suse-rancher-supportconfig I finally didn't used golang but used gum instead add-emoji

    SUSE's supportconfig support tool collects data from the SUSE Operating system. Rancher's rancher2_logs_collector.sh support tool does the same for RKE2/K3s.

    Wouldn't be nice to have a way to run both and collect all data for SUSE based RKE2/K3s clusters? Wouldn't be even better with a fancy TUI tool like bubbletea?

    Ideally the output should be an html page where you can see the logs/data directly from the browser.

    Goals

    • Familiarize myself with both supportconfig and rancher2_logs_collector.sh tools
    • Refresh my golang knowledge
    • Have something that works at the end of the hackweek ("works" may vary add-emoji )
    • Be better in naming things

    file-organizer: A CLI Tool for Efficient File Management by okhatavkar

    Description

    Create a Go-based CLI tool that helps organize files in a specified folder by sorting them into subdirectories based on defined criteria, such as file type or creation date. Users will pass a folder path as an argument, and the tool will process and organize the files within it.

    Goals

    • Develop Go skills by building a practical command-line application.
    • Learn to manage and manipulate files and directories in Go using standard libraries.
    • Create a tool that simplifies file management, making it easier to organize and maintain directories.

    Resources

    • Go Standard Libraries: Utilize os, filepath, and time for file operations.
    • CLI Development: Use flag for basic argument parsing or consider cobra for enhanced functionality.
    • Go Learning Material: Go by Example and The Go Programming Language Documentation.

    Features

    • File Type Sorting: Automatically move files into subdirectories based on their extensions (e.g., documents, images, videos).
    • Date-Based Organization: Add an option to organize files by creation date into year/month folders.
    • User-Friendly CLI: Build intuitive commands and clear outputs for ease of use. This version maintains the core idea of organizing files efficiently while focusing on Go development and practical file management.

    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

    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


    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

    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.
