Uyuni/SUSE Manager containerization project
Deploy Uyuni as an app from the Rancher marketplace - or install via Helm on any Kubernetes cluster, on any OS, or any Public Cloud.
The dream
Allow Uyuni to be installable as "app": a Helm chart containerized application which can run on any K8s cluster, ideally from the Rancher Marketplace.
It is a long road to get there, and this HackWeek project is to get started.
Project coordination is on the Wiki project page
Looking for hackers with the skills:

In case we wanted to build the containers in OBS, which would be my suggestion, there is some examples here of development containers we built so far, for example one that includes the database:

What does this mean? "we will need a solution about commandline tools. Would it be possible to create a UI around them like Rancher does?"
Do you mean in order to avoid connecting to the container to run those CLI tools in there?
One alternative would be to build such a UI but you still have the problem this still gives you access to the "internals" of Uyuni. Ideally, we want to use the CLI tools remotely (connecting to Uyuni, Salt, database or whatever, always via single ingress endpoint), or even to replace them with proper WebUI, API, etc calls.

Yes, the point is that there is no way to "connect to a container", unless the container runs
sshdwhich is not the norm. One can spin up a container with just one commandline tool inside (example) but that might be cumbersome or not possible depending on the tool.In principle, one wants any commandline tool's functionality to be equivalently exposed via a Web UI, which is of course a good long-term goal.
In the meantime, a stopgap solution could be to offer some commandline tools inside a text area in the Web UI. That won't be a proper shell (say,
bash), but something tailored to the app such as ourspacecmd. Rancher does something similar withkubectl.Note that I am not even convinced this is the best solution for this case here, it's just something that could be viable to speed things up.

I see your point. Makes sense. Maybe Ricardo's uyuni-cli can help here, otherwise there's a ton of tools to enable via WebUI.
Another alternative would be to make all the CLI tools work remotely. Some of them already do.
Another important case: logs. How to view them? Add them to the WebUI? Some tool to show logs remotely? Another thing to add to uyuni-cli?

Another way to offer CLI tools is to build a container that gets run as a sidecar and can be turned on or off depending on context. Then if you wanted to give easy access, you could also package code-server in that tools container to give a nice IDE/terminal access in the browser.
Eventually, K8s will offer ephemeral containers (alpha currently) and this would be even easier and more secure.
(sorry if this gets duplicated, I apparently wasn't logged in while commenting the first attempt)

over 4 years ago by moio | Reply
In a K8S environment, you expect the framework itself to take care of logs. It's similar to
systemd- you just dump them all to stdout and then the framework handles it for you.Of course we might end up with fatter-than-ideal containers which contain multiple servers, and then we will need to expose logs in another way. The starting point will be a mounted directory inside of the container, then we can assess how big of a problem we actually have.
In any case: it's a problem bleeping both under my radar and MC's!

I played with Rancher in my own hack week project, and I came up with that exact same idea, just to realize that you guys have already been working on it.
After this hack week, how far do you think you are away from a working helm-installable Uyuni server demo? Another hack week? Or is this a major undertaking?

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

Testing and adding GNU/Linux distributions on Uyuni by juliogonzalezgil
Join the Gitter channel! https://gitter.im/uyuni-project/hackweek
Uyuni is a configuration and infrastructure management tool that saves you time and headaches when you have to manage and update tens, hundreds or even thousands of machines. It also manages configuration, can run audits, build image containers, monitor and much more!
Currently there are a few distributions that are completely untested on Uyuni or SUSE Manager (AFAIK) or just not tested since a long time, and could be interesting knowing how hard would be working with them and, if possible, fix whatever is broken.
For newcomers, the easiest distributions are those based on DEB or RPM packages. Distributions with other package formats are doable, but will require adapting the Python and Java code to be able to sync and analyze such packages (and if salt does not support those packages, it will need changes as well). So if you want a distribution with other packages, make sure you are comfortable handling such changes.
No developer experience? No worries! We had non-developers contributors in the past, and we are ready to help as long as you are willing to learn. If you don't want to code at all, you can also help us preparing the documentation after someone else has the initial code ready, or you could also help with testing :-)
The idea is testing Salt and Salt-ssh clients, but NOT traditional clients, which are deprecated.
To consider that a distribution has basic support, we should cover at least (points 3-6 are to be tested for both salt minions and salt ssh minions):
- Reposync (this will require using spacewalk-common-channels and adding channels to the .ini file)
- Onboarding (salt minion from UI, salt minion from bootstrap scritp, and salt-ssh minion) (this will probably require adding OS to the bootstrap repository creator)
- Package management (install, remove, update...)
- Patching
- Applying any basic salt state (including a formula)
- Salt remote commands
- Bonus point: Java part for product identification, and monitoring enablement
- Bonus point: sumaform enablement (https://github.com/uyuni-project/sumaform)
- Bonus point: Documentation (https://github.com/uyuni-project/uyuni-docs)
- Bonus point: testsuite enablement (https://github.com/uyuni-project/uyuni/tree/master/testsuite)
If something is breaking: we can try to fix it, but the main idea is research how supported it is right now. Beyond that it's up to each project member how much to hack :-)
- If you don't have knowledge about some of the steps: ask the team
- If you still don't know what to do: switch to another distribution and keep testing.
This card is for EVERYONE, not just developers. Seriously! We had people from other teams helping that were not developers, and added support for Debian and new SUSE Linux Enterprise and openSUSE Leap versions :-)

Flaky Tests AI Finder for Uyuni and MLM Test Suites by oscar-barrios
Description
Our current Grafana dashboards provide a great overview of test suite health, including a panel for "Top failed tests." However, identifying which of these failures are due to legitimate bugs versus intermittent "flaky tests" is a manual, time-consuming process. These flaky tests erode trust in our test suites and slow down development.
This project aims to build a simple but powerful Python script that automates flaky test detection. The script will directly query our Prometheus instance for the historical data of each failed test, using the jenkins_build_test_case_failure_age metric. It will then format this data and send it to the Gemini API with a carefully crafted prompt, asking it to identify which tests show a flaky pattern.
The final output will be a clean JSON list of the most probable flaky tests, which can then be used to populate a new "Top Flaky Tests" panel in our existing Grafana test suite dashboard.
Goals
By the end of Hack Week, we aim to have a single, working Python script that:
- Connects to Prometheus and executes a query to fetch detailed test failure history.
- Processes the raw data into a format suitable for the Gemini API.
- Successfully calls the Gemini API with the data and a clear prompt.
- Parses the AI's response to extract a simple list of flaky tests.
- Saves the list to a JSON file that can be displayed in Grafana.
- New panel in our Dashboard listing the Flaky tests

Uyuni read-only replica by cbosdonnat
Description
For now, there is no possible HA setup for Uyuni. The idea is to explore setting up a read-only shadow instance of an Uyuni and make it as useful as possible.
Possible things to look at:
- live sync of the database, probably using the WAL. Some of the tables may have to be skipped or some features disabled on the RO instance (taskomatic, PXT sessions…)
- Can we use a load balancer that routes read-only queries to either instance and the other to the RW one? For example, packages or PXE data can be served by both, the API GET requests too. The rest would be RW.
Goals
- Prepare a document explaining how to do it.
- PR with the needed code changes to support it
Move Uyuni Test Framework from Selenium to Playwright + AI by oscar-barrios
Description
This project aims to migrate the existing Uyuni Test Framework from Selenium to Playwright. The move will improve the stability, speed, and maintainability of our end-to-end tests by leveraging Playwright's modern features. We'll be rewriting the current Selenium code in Ruby to Playwright code in TypeScript, which includes updating the test framework runner, step definitions, and configurations. This is also necessary because we're moving from Cucumber Ruby to CucumberJS.
If you're still curious about the AI in the title, it was just a way to grab your attention. Thanks for your understanding.
Goals
- Migrate Core tests including Onboarding of clients
- Improve test reliabillity: Measure and confirm a significant reduction of flakynes.
- Implement a robust framework: Establish a well-structured and reusable Playwright test framework using the CucumberJS

Uyuni Health-check Grafana Troubleshooter by ygutierrez
Description
This project explores the feasibility of using the open-source Grafana LLM plugin to enhance the Uyuni Health-check tool with LLM capabilities. The idea is to integrate a chat-based "AI Troubleshooter" directly into existing dashboards, allowing users to ask natural-language questions about errors, anomalies, or performance issues.
Goals
- Investigate if and how the
grafana-llm-appplug-in can be used within the Uyuni Health-check tool. - Investigate if this plug-in can be used to query LLMs for troubleshooting scenarios.
- Evaluate support for local LLMs and external APIs through the plugin.
- Evaluate if and how the Uyuni MCP server could be integrated as another source of information.
