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?
Resources
- https://github.com/ori-edge/k8s_gateway/issues/36
- https://github.com/coredns/coredns/issues/2465#issuecomment-593910983
EDIT: Feature mostly complete. An unfinished PR lies here. Successfully tested working on homelab cluster.

Multi-pod, autoscalable Elixir application in Kubernetes using K8s resources by socon
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.

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.
Rancher/k8s Trouble-Maker by tonyhansen

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

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

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.
Resources
None so far, this is just an idea.

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.
