Description
Elixir / Erlang use their own solutions to create clusters that work together. Kubernetes provide its own orchestration. Due to the nature of the BEAM, it looks a very promising technology for applications that run in Kubernetes and requite to be always on, specifically if they are created as web pages using Phoenix.
Goals
- Investigate and provide solutions that work in Phoenix LiveView using Kubernetes resources, so a multi-pod application can be used
- Provide an end to end example that creates and deploy a container from source code.

Learn how to integrate Elixir and Phoenix Liveview with LLMs by ninopaparo
Description
Learn how to integrate Elixir and Phoenix Liveview with LLMs by building an application that can provide answers to user queries based on a corpus of custom-trained data.
Goals
Develop an Elixir application via the Phoenix framework that:
- Employs Retrieval Augmented Generation (RAG) techniques
- Supports the integration and utilization of various Large Language Models (LLMs).
- Is designed with extensibility and adaptability in mind to accommodate future enhancements and modifications.

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 )

Learn enough Golang and hack on CoreDNS by jkuzilek
Description
I'm implementing a split-horizon DNS for my home Kubernetes cluster to be able to access my internal (and external) services over the local network through public domains. I managed to make a PoC with the k8s_gateway plugin for CoreDNS. However, I soon found out it responds with IPs for all Gateways assigned to HTTPRoutes, publishing public IPs as well as the internal Loadbalancer ones.
To remedy this issue, a simple filtering mechanism has to be implemented.
Goals
- Learn an acceptable amount of Golang
- Implement GatewayClass (and IngressClass) filtering for k8s_gateway
- Deploy on homelab cluster
- Profit?

EDIT: Feature mostly complete. An unfinished PR lies here. Successfully tested working on homelab cluster.
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.

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
kubectl clone: Seamlessly Clone Kubernetes Resources Across Multiple Rancher Clusters and Projects by dpunia
Description
kubectl clone is a kubectl plugin that empowers users to clone Kubernetes resources across multiple clusters and projects managed by Rancher. It simplifies the process of duplicating resources from one cluster to another or within different namespaces and projects, with optional on-the-fly modifications. This tool enhances multi-cluster resource management, making it invaluable for environments where Rancher orchestrates numerous Kubernetes clusters.
Goals
- Seamless Multi-Cluster Cloning
- Clone Kubernetes resources across clusters/projects with one command.
- Simplifies management, reduces operational effort.
Resources
Rancher & Kubernetes Docs
- Rancher API, Cluster Management, Kubernetes client libraries.
Development Tools
- Kubectl plugin docs, Go programming resources.
Building and Installing the Plugin
- Set Environment Variables: Export the Rancher URL and API token:
export RANCHER_URL="https://rancher.example.com"
export RANCHER_TOKEN="token-xxxxx:xxxxxxxxxxxxxxxxxxxx"
- Build the Plugin: Compile the Go program:
go build -o kubectl-clone ./pkg/
- Install the Plugin:
Move the executable to a directory in your
PATH
:
mv kubectl-clone /usr/local/bin/
Ensure the file is executable:
chmod +x /usr/local/bin/kubectl-clone
- Verify the Plugin Installation: Test the plugin by running:
kubectl clone --help
You should see the usage information for the kubectl-clone
plugin.
Usage Examples
- Clone a Deployment from One Cluster to Another:
kubectl clone --source-cluster c-abc123 --type deployment --name nginx-deployment --target-cluster c-def456 --new-name nginx-deployment-clone
- Clone a Service into Another Namespace and Modify Labels:
