Make it faster!
There are use cases that put the Kubernetes API under heavy load - using Rancher at scale can be one of them.
Also, there are use cases in which a connection to the Kubernetes API might not always be present, or with good bandwidth - using Rancher for edge use cases can be one of them.
This project aims to create a local cache serving data from the Kubernetes API - with good performance and displaying last-good-results on a flaky connection.
Goal for this Hackweek
Implement Proof-Of-Concept client-go components backed by SQLite.

Install Uyuni on Kubernetes in cloud-native way by cbosdonnat
Description
For now installing Uyuni on Kubernetes requires running mgradm
on a cluster node... which is not what users would do in the Kubernetes world. The idea is to implement an installation based only on helm charts and probably an operator.
Goals
Install Uyuni from Rancher UI.

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
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
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
)

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
.
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
- Go code improvement
What you might learn
Harvester CLI might be interesting to you if you want to learn more about:
- GitHub Actions
- Harvester as a SUSE Product
- Go programming language
- Kubernetes API

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
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
andrancher2_logs_collector.sh
tools - Refresh my golang knowledge
- Have something that works at the end of the hackweek ("works" may vary
)
- 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.
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

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.
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).
