Rancher Support Matrix CLI Helper

A tool to bring the Rancher Support Matrix info into your CLI.

> Update: This project was not completed during hackweek 22, however will still continue development as possible and our team is excited to continue the efforts next year! We did make significant progress on both: a) producing a JSON static API scheme and b) a system to store the Rancher release version support information.

Project Description

The goal of this tool (for V1) is quite simply to pull up the Support Matrix info based on user input.

Project Components

CLI Tool - GoLang

This is the meat and potatoes of the Hackweek project. The other parts are important, but are all a means to this end.

The goal is to build it in Go so as to provide a native binary for each platform. This also keeps things close to K8s and Rancher, as opposed to Rust or other popular CLI languages.

Support Matrix Structured Data/API

This component is the data backing the CLI tool - it will be provided as a blob of structured data hosted on GH pages.

In a strict sense this (mostly) static data will function as if it were an API - however it is not interactive at all. It will simply be a statically rendered blob of data hosted online. So only pure GET requests rather than all the HTTP verbs like a true API. The final Scheme of this "API" has not been decided yet - however it will be informed by the needs of the CLI tool.

Matrix Refresh Tool

This component will be used to keep the publish Support Matrix Structured Data fresh and in sync.

Currently the data is not published in a way that is structured. This means we need to either: a) manually massage the data into the right formats, or b) create a system to sync that information. This tool is currently the furthest developed part of the project - having a mostly working proof of concept completed.

It is unlikely that this tool will be published in the open. It merely exists as an "internal" tool to facilitate publishing the data in a structured way. Similarly, this tool is least likely to need collaboration for Hackweek as the other components are the real goal.

Inspiration

As a Premium Support Engineer focused on Rancher we often need to review the support matrix. This is critical to ensure the Rancher instance is properly configured within the expected versions. While doing this via the webpage is fine, as tech staff we often spend a lot of time in CLIs. To that end bringing this essential tool even closer to our "main workflows" is a no brainer.

Mentioned above, the initial goal of hack week is simply to provide the information via CLI report. While more could potentially be achieved within Hackweek, this conservative goal was selected to allow enough time to organize the data at hand. The project will be in much better footing when this data is organized and refresh methods established.

Down the road it can be expanded to provide more functionality. E.g. Validation mode - enter all the versions in use and it will highlight potential issues, Upgrade Path - input current versions and desired Rancher version.

Goal for this Hackweek

  • Establish a structured data source for Support Matrix,
  • Publish (to GitHub pages) the structured data version of Support Matrix,
  • Create a (golang) CLI tool to provide Support matrix info.

      Just wanted to give a brief update on the progress as it's mid-week already.

      Ian and Myself have been working together on the design for the "structured data" version of the matrix. Our hope is that we will be able to land on a good format to export that as and publish a few versions worth of the data. Then start working on the golang CLI client that is the "real end goal".

      Even though these parts I've been working on are just "bootstrap" work to get the CLI project started it's been great learning. I've updated the project info a bit to reflect some changes. I also published a mermaidjs diagram of the DB design being used for the CLI import tool here - https://gist.github.com/mallardduck/6bc19ed05029132370b8dda6b603f99e.

      Here is an example of the API we created for the "index":

      ○ → curl http://rancher-support-matrix-full.test/ |jq { "about": "This is a static API that contains the Support information for Rancher releases!", "base_url": "http://rancher-support-matrix-full.test", "routes": { "api.rancherRelease": "api/release/{rancherRelease}.json", "api.rancherRelease.rkeK8sRuntimes": "api/release/{rancherRelease}/RkeK8sRuntimes.json", "api.rancherRelease.rkeK8sRuntimePair": "api/release/{rancherRelease}/RkeK8sRuntimePair.json", "api.rancherRelease.rkeDistroVersionDockerPair": "api/release/{rancherRelease}/RkeDistroVersionDockerPair.json", "api.rancherRelease.hostedRuntimes": "api/release/{rancherRelease}/HostedRuntimeVersions.json" }, "rancherReleases": [ { "data": { "version": "2.6.3" }, "links": { "self": "http://rancher-support-matrix-full.test/api/release/2.6.3.json" } } ] }

    Rancher microfrontend extensions by ftorchia

    Description

    Rancher UI Extensions allow users, developers, partners, and customers to extend and enhance the Rancher UI. Extensions are Helm charts that can only be installed once into a cluster. The charts contain a UI built package that is downloaded and linked to the Host UI at runtime; this means that the extension pkg needs to be implemented using the same technology and have the same APIs as Rancher UI.

    Goals

    We want to create a new type of Rancher extension, based on microfrontend pattern. The extension is served in a docker container in the k8s clusters and embedded in the host UI; this would guarantee us to be able to create extensions unrelated to the rancher UI architecture, in any technology.

    Non Goals

    We want to apply the microfrontend pattern to the product-level extensions; we don't want to apply it to cluster-level extensions.

    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

    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.

    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

    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.

    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

    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

    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.

    • 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.

    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

    • Kubernetes API

    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.

    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.

    None so far, this is just an idea.

    Mammuthus - The NFS-Ganesha inside Kubernetes controller by vcheng

    Description

    As the user-space NFS provider, the NFS-Ganesha is wieldy use with serval projects. e.g. Longhorn/Rook. We want to create the Kubernetes Controller to make configuring NFS-Ganesha easy. This controller will let users configure NFS-Ganesha through different backends like VFS/CephFS.

    Goals

    1. Create NFS-Ganesha Package on OBS: nfs-ganesha5, nfs-ganesha6
    2. Create NFS-Ganesha Container Image on OBS: Image
    3. Create a Kubernetes controller for NFS-Ganesha and support the VFS configuration on demand. Mammuthus

    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

    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.

    Goals

    • iSCSI Boot Option: Enable nodes to boot directly from iSCSI volumes
    • Mounting iSCSI Volumes within the Filesystem: Implement support for mounting iSCSI devices at various points within the filesystem

    Resources

    https://warewulf.org/

    Steps

    • add generic framework to handle remote ressource/filesystems to wwctl [ ]
    • add iSCSI handling to wwctl configure [ ]
    • add iSCSI to dracut files [ ]
    • test it [ ]

    terraform-provider-feilong by e_bischoff

    Project Description

    People need to test operating systems and applications on s390 platform.

    Installation from scratch solutions include:

    • just deploy and provision manually add-emoji (with the help of ftpboot script, if you are at SUSE)
    • use s3270 terminal emulation (used by openQA people?)
    • use LXC from IBM to start CP commands and analyze the results
    • use zPXE to do some PXE-alike booting (used by the orthos team?)
    • use tessia to install from scratch using autoyast
    • use libvirt for s390 to do some nested virtualization on some already deployed z/VM system
    • directly install a Linux kernel on a LPAR and use kvm + libvirt from there

    Deployment from image solutions include:

    • use ICIC web interface (openstack in disguise, contributed by IBM)
    • use ICIC from the openstack terraform provider (used by Rancher QA)
    • use zvm_ansible to control SMAPI
    • connect directly to SMAPI low-level socket interface

    IBM Cloud Infrastructure Center (ICIC) harnesses the Feilong API, but you can use Feilong without installing ICIC, provided you set up a "z/VM cloud connector" into one of your VMs following this schema.

    What about writing a terraform Feilong provider, just like we have the terraform libvirt provider? That would allow to transparently call Feilong from your main.tf files to deploy and destroy resources on your system/z.

    Other Feilong-based solutions include:

    • make libvirt Feilong-aware
    • simply call Feilong from shell scripts with curl
    • use zvmconnector client python library from Feilong
    • use zthin part of Feilong to directly command SMAPI.

    Goal for Hackweek 23

    My final goal is to be able to easily deploy and provision VMs automatically on a z/VM system, in a way that people might enjoy even outside of SUSE.

    My technical preference is to write a terraform provider plugin, as it is the approach that involves the least software components for our deployments, while remaining clean, and compatible with our existing development infrastructure.

    Goals for Hackweek 24

    Feilong provider works and is used internally by SUSE Manager team. Let's push it forward!

    Let's add support for fiberchannel disks and multipath.

    Goals for Hackweek 25

    • Finish support for fiberchannel disks and multipath
    • Fix problems with registration on hashicorp providers registry
