Project Description
Idea is to predefine a set of security policies for popular container applications just for example MySQL, Nginx etc..., with these predefined security policies, users can just download unpack it to use. No need to worry too much about detailed security settings/configurations for this application container. The policies could be any policies that Kubernetes supported and/or NeuVector supported.
Today, there are security policies being supported by Kubernetes like NetworkPolicy, there are extended policies like KubeWarden admission control policies, there are advanced security policy like NeuVector's L7 network policy, process & file policy etc... All these policies are providing functions to secure a Kubernetes environment. From end user point of view, it is good but not convenient enough to use unless users are security experts. So idea is, we could create many predefined security policies for many popular container applications, define these as a Kubernetes standard format like CRD extension just for example. Make these the building blocks coupled with the app images, so when users pull a container, a security policy can be imported at same time. The basic security settings (baseline) will be in place right away. If NeuVector was installed already then the enforcement is in place as well. Most of the users will have basic security in place by doing almost nothing. (of course, if it's necessary, users can still customize or fine tune the predefined templates.)
Security needs to be easy to use but still strong enough to protect, a lot of security postures/configurations/policies could be already defined when this application container image is created. These security manifest is different per apps but it is relatively stable per container as well. So, if we can create or generate security policy templates for popular application images, eventually make some of solid ones a built-in template, or even grow to be a hosted security policy hub. It could be a new critical way to secure Kubernetes world.
Goal for this Hackweek
Study this deeper, choose a few popular applications and make a prototype/demo to proof the concept.
Resources
Some of the policies might not be a good fit to be profiled as manifest. Here we will be focusing on relatively stable application security posture/configuration/runtime policies. Starting point could be look into these:

vex8s-controller: a kubernetes controller to automatically generate VEX documents of your running workloads by agreggi
Description
vex8s-controller is an add-on for SBOMscanner project.
Its purpose is to automatically generate VEX documents based on the workloads running in a kubernetes cluster. It integrates directly with SBOMscanner by monitoring VulnerabilityReports created for container images and producing corresponding VEX documents that reflect each workload’s SecurityContext.
Here's the workflow explained:
- sbomscanner scans for images in registry
- generates a
VulnerabilityReportwith the image CVEs - vex8s-controller triggers when a workload is scheduled on the cluster and generates a VEX document based on the workload
SecurityContextconfiguration - the VEX document is provided by vex8s-controller using a VEX Hub repository
- sbomscanner configure the VEXHub CRD to point to the internal vex8s-controller VEX Hub repository
Goals
The objective is to build a kubernetes controller that uses the vex8s mitigation rules engine to generate VEX documents and serve them through an internal VEX Hub repository within the cluster.
SBOMscanner can then be configured to consume VEX data directly from this in-cluster repository managed by vex8s-controller.

Looking at Rust if it could be an interesting programming language by jsmeix
Get some basic understanding of Rust security related features from a general point of view.
This Hack Week project is not to learn Rust to become a Rust programmer. This might happen later but it is not the goal of this Hack Week project.
The goal of this Hack Week project is to evaluate if Rust could be an interesting programming language.
An interesting programming language must make it easier to write code that is correct and stays correct when over time others maintain and enhance it than the opposite.

A CLI for Harvester by mohamed.belgaied
Harvester does not officially come with a CLI tool, the user is supposed to interact with Harvester mostly through the UI. Though it is theoretically possible to use kubectl to interact with Harvester, the manipulation of Kubevirt YAML objects is absolutely not user friendly. 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).

OpenPlatform Self-Service Portal by tmuntan1
Description
In SUSE IT, we developed an internal developer platform for our engineers using SUSE technologies such as RKE2, SUSE Virtualization, and Rancher. While it works well for our existing users, the onboarding process could be better.
To improve our customer experience, I would like to build a self-service portal to make it easy for people to accomplish common actions. To get started, I would have the portal create Jira SD tickets for our customers to have better information in our tickets, but eventually I want to add automation to reduce our workload.
Goals
- Build a frontend website (Angular) that helps customers create Jira SD tickets.
- Build a backend (Rust with Axum) for the backend, which would do all the hard work for the frontend.

Self-Scaling LLM Infrastructure Powered by Rancher by ademicev0
Self-Scaling LLM Infrastructure Powered by Rancher
Description
The Problem
Running LLMs can get expensive and complex pretty quickly.
Today there are typically two choices:
- Use cloud APIs like OpenAI or Anthropic. Easy to start with, but costs add up at scale.
- Self-host everything - set up Kubernetes, figure out GPU scheduling, handle scaling, manage model serving... it's a lot of work.
What if there was a middle ground?
Project Repository: github.com/alexander-demicev/llmserverless
What This Project Does
A key feature is hybrid deployment: requests can be routed based on complexity or privacy needs. Simple or low-sensitivity queries can use public APIs (like OpenAI), while complex or private requests are handled in-house on local infrastructure. This flexibility allows balancing cost, privacy, and performance - using cloud for routine tasks and on-premises resources for sensitive or demanding workloads.
A complete, self-scaling LLM infrastructure that:
- Scales to zero when idle (no idle costs)
- Scales up automatically when requests come in
- Adds more nodes when needed, removes them when demand drops
- Runs on any infrastructure - laptop, bare metal, or cloud
Think of it as "serverless for LLMs" - focus on building, the infrastructure handles itself.
How It Works
A combination of open source tools working together:
Flow:
- Users interact with OpenWebUI (chat interface)
- Requests go to LiteLLM Gateway
- LiteLLM routes requests to:
- Ollama (Knative) for local model inference (auto-scales pods)
- Or cloud APIs for fallback
- Cluster Autoscaler scales nodes up/down as needed
- Fleet keeps everything in sync via GitOps

The Agentic Rancher Experiment: Do Androids Dream of Electric Cattle? by moio
Rancher is a beast of a codebase. Let's investigate if the new 2025 generation of GitHub Autonomous Coding Agents and Copilot Workspaces can actually tame it. 
The Plan
Create a sandbox GitHub Organization, clone in key Rancher repositories, and let the AI loose to see if it can handle real-world enterprise OSS maintenance - or if it just hallucinates new breeds of Kubernetes resources!
Specifically, throw "Agentic Coders" some typical tasks in a complex, long-lived open-source project, such as:
❥ The Grunt Work: generate missing GoDocs, unit tests, and refactorings. Rebase PRs.
❥ The Complex Stuff: fix actual (historical) bugs and feature requests to see if they can traverse the complexity without (too much) human hand-holding.
❥ Hunting Down Gaps: find areas lacking in docs, areas of improvement in code, dependency bumps, and so on.
If time allows, also experiment with Model Context Protocol (MCP) to give agents context on our specific build pipelines and CI/CD logs.
Why?
We know AI can write "Hello World." and also moderately complex programs from a green field. But can it rebase a 3-month-old PR with conflicts in rancher/rancher? I want to find the breaking point of current AI agents to determine if and how they can help us to reduce our technical debt, work faster and better. At the same time, find out about pitfalls and shortcomings.
The Outputs
❥ A "State of the Agentic Union" for SUSE engineers, detailing what works, what explodes, and how much coffee we can drink while the robots do the rebasing.
❥ Honest, Daily Updates With All the Gory Details
