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).
Resources
- Cluster API: https://cluster-api.sigs.k8s.io/
- Kubewarden: https://docs.kubewarden.io/

Rancher Cluster Lifecycle Visualizer by jferraz
Description
Rancher’s v2 provisioning system represents each downstream cluster with several Kubernetes custom resources across multiple API groups, such as clusters.provisioning.cattle.io and clusters.management.cattle.io. Understanding why a cluster is stuck in states like "Provisioning", "Updating", or "Unavailable" often requires jumping between these resources, reading conditions, and correlating them with agent connectivity and known failure modes.
This project will build a Cluster Lifecycle Visualizer: a small, read-only controller that runs in the Rancher management cluster and generates a single, human-friendly view per cluster. It will watch Rancher cluster CRDs, derive a simplified lifecycle phase, keep a history of phase transitions from installation time onward, and attach a short, actionable recommendation string that hints at what the operator should check or do next.
Goals
- Provide a compact lifecycle summary for each Rancher-managed cluster (e.g.
Provisioning,WaitingForClusterAgent,Active,Updating,Error) derived fromprovisioning.cattle.io/v1 Clusterandmanagement.cattle.io/v3 Clusterstatus and conditions. - Maintain a phase history for each cluster, allowing operators to see how its state evolved over time since the visualizer was installed.
- Attach a recommended action to the current phase using a small ruleset based on common Rancher failure modes (for example, cluster agent not connected, cluster still stabilizing after an upgrade, or generic error states), to improve the day-to-day debugging experience.
- Deliver an easy-to-install, read-only component (single YAML or small Helm chart) that Rancher users can deploy to their management cluster and inspect via
kubectl get/describe, without UI changes or direct access to downstream clusters. - Use idiomatic Go, wrangler, and Rancher APIs.
Resources
- Rancher Manager documentation on RKE2 and K3s cluster configuration and provisioning flows.
- Rancher API Go types for
provisioning.cattle.io/v1andmanagement.cattle.io/v3(from therancher/rancherrepository or published Go packages). - Existing Rancher architecture docs and internal notes about cluster provisioning, cluster agents, and node agents.
- A local Rancher management cluster (k3s or RKE2) with a few test downstream clusters to validate phase detection, history tracking, and recommendations.
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
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
DONE in 2025 (out of Hackweek)
- Support of ClusterClass
- Add to
clusterctlcommunity providers, you can add it directly withclusterctl - Testing on newer versions of Harvester v1.4.X and v1.5.X
- Support for
clusterctl generate cluster ... - Improve Status Conditions to reflect current state of Infrastructure
- Improve CI (some bugs for release creation)
Goals for HackWeek 2025
- FIRST and FOREMOST, any topic is important to you
- Add e2e testing
- Certify the provider for Rancher Turtles
- Add Machine pool labeling
- Add PCI-e passthrough capabilities.
- Other improvement suggestions are welcome!
Thanks to @isim and Dominic Giebert for their contributions!

Create a go module to wrap happy-compta.fr by cbosdonnat
Description
https://happy-compta.fr is a tool for french work councils simple book keeping. While it does the job, it has no API to work with and it is tedious to enter loads of operations.
Goals
Write a go client module to be used as an API to programmatically manipulate the tool.
Writing an example tool to load data from a CSV file would be good too.
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
Resources
- CONTRIBUTING readme
- Go libvirt library in use by the project
- Terraform plugin development
- "Good first issue" list

HTTP API for nftables by crameleon
Background
The idea originated in https://progress.opensuse.org/issues/164060 and is about building RESTful API which translates authorized HTTP requests to operations in nftables, possibly utilizing libnftables-json(5).
Originally, I started developing such an interface in Go, utilizing https://github.com/google/nftables. The conversion of string networks to nftables set elements was problematic (unfortunately no record of details), and I started a second attempt in Python, which made interaction much simpler thanks to native nftables Python bindings.
Goals
- Find and track the issue with google/nftables
- Revisit and polish the Go or Python code (prefer Go, but possibly depends on implementing missing functionality), primarily the server component
- Finish functionality to interact with nftables sets (retrieving and updating elements), which are of interest for the originating issue
- Align test suite
- Packaging
Resources
- https://git.netfilter.org/nftables/tree/py/src/nftables.py
- https://git.com.de/Georg/nftables-http-api (to be moved to GitHub)
- https://build.opensuse.org/package/show/home:crameleon:containers/pytest-nftables-container
Results
- Started new https://github.com/tacerus/nftables-http-api.
- First Go nftables issue was related to set elements needing to be added with different start and end addresses - coincidentally, this was recently discovered by someone else, who added a useful helper function for this: https://github.com/google/nftables/pull/342.
- Further improvements submitted: https://github.com/google/nftables/pull/347.
Side results
Upon starting to unify the structure and implementing more functionality, missing JSON output support was noticed for some subcommands in libnftables. Submitted patches here as well:
