[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
.
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

Is the project ongoing? I might be interested!
I've done something similar a couple of years ago, but more wide services capable https://github.com/Wabri/Imp I had something also for redmine that I was working on, but the laptop where I was working on was of the company I left before suse and sadly I totally forgot to push that feature branch.

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)

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 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:
- Add more Unit Tests
- Improve Status Conditions for some phases
- Add cloud provider config generation
- Testing with Harvester v1.3.2
- Template improvements
- Issues creation
Thanks to @isim and Dominic Giebert for their contributions!

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:
- add containerized image for ddflare
- extend ddflare to be able to add and remove DNS records (and not just update existing ones)
- add documentation, covering also a sample pod deployment for Kubernetes
- write a ddflare Kubernetes operator to enable domain management via Kubernetes resources (using kubebuilder)
Available tasks and improvements tracked on ddflare github.

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

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

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
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:
- Add more Unit Tests
- Improve Status Conditions for some phases
- Add cloud provider config generation
- Testing with Harvester v1.3.2
- Template improvements
- Issues creation
Thanks to @isim and Dominic Giebert for their contributions!
Resources
Looking for help from anyone interested in Cluster API (CAPI) or who wants to learn more about Harvester.
This will be an infrastructure provider for Cluster API. Some background reading for the CAPI aspect:

CVE portal for SUSE Rancher products by gmacedo
Description
Currently it's a bit difficult for users to quickly see the list of CVEs affecting images in Rancher, RKE2, Harvester and Longhorn releases. Users need to individually look for each CVE in the SUSE CVE database page - https://www.suse.com/security/cve/ . This is not optimal, because those CVE pages are a bit hard to read and contain data for all SLE and BCI products too, making it difficult to easily see only the CVEs affecting the latest release of Rancher, for example. We understand that certain costumers are only looking for CVE data for Rancher and not SLE or BCI.
Goals
The objective is to create a simple to read and navigate page that contains only CVE data related to Rancher, RKE2, Harvester and Longhorn, where it's easy to search by a CVE ID, an image name or a release version. The page should also provide the raw data as an exportable CSV file.
It must be an MVP with the minimal amount of effort/time invested, but still providing great value to our users and saving the wasted time that the Rancher Security team needs to spend by manually sharing such data. It might not be long lived, as it can be replaced in 2-3 years with a better SUSE wide solution.
Resources
- The page must be simple and easy to read.
- The UI/UX must be as straightforward as possible with minimal visual noise.
- The content must be created automatically from the raw data that we already have internally.
- It must be updated automatically on a daily basis and on ad-hoc runs (when needed).
- The CVE status must be aligned with VEX.
- The raw data must be exportable as CSV file.
- Ideally it will be written in Go or pure Shell script with basic HTML and no external dependencies in CSS or JS.
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:
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
Days Three and Day Four
Created two backend plugins for Backstage:
- Catalog Entity Provider - this imports users from Rancher into Backstage
- 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
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
