Since SUSE Manager doesn't scale out and stacking it into another pyramid of susemanagers won't help here, the real architectural changes needs to be done to achieve true scale-out of this product. This hackweek project is about how to Turn SUSE Manager into a cluster.
Areas to be tackled:
- Distributed FS for storage
- Distributed messaging bus
- Distributed KV for metadata
- Control Node prototype (this component turns a SUSE Manager into a stateless-ish event-driven node, where SUSE Manager in a future is deployed into a container -> Kubernetes)
- Cluster Director prototype (this component orchestrates the entire cluster via events)
- API Gateway, providing 100% compatible API across all SUSE Manager nodes (this is done, demoed at SUMA Winter Summit 2020)
- Slightly modified SUSE Manager peripherals (reposync, DB etc).
- Client daemon, which is used to bind a single registered system to a cluster node according to Cluster Director service (on shrink, grow, rebalance and disaster recovery events).
The idea is to solve a set of core problems how to turn technologically outdated Uyuni Server / SUMA into a modern cloud-native cluster node, so with after a reasonable time this could be turned into a real product for SUSE Manager.
Progress
Day One (Monday, 10 Feb)
Storm seems over. Realised this website doesn't allow editing comments :astonished:.
Got working initial Cluster Daemon that runs REST API and talks to the distributed KV database.
Got working Client Daemon for every Client System. So far it can:
- Pool the Client System to the cluster for staging
- Talk to Cluster Director (CD) and get the status
- Switch/reconfigure Salt Minion according to the CD's directives
Got initial tool (Python) that calls Cluster API. So far it is too simple to describe. 
Got initial Cluster Director with OpenAPI spec (Swagger) running.

The day is over. Did many refactorings, found that Gin doesn't do form parsing from the body on DELETE method but solved it, not yet haven't finished Zones management (which is damn easy now, but argghh still!).
Day Two (Tuesday, 11 Feb)
Turned mgr-clbd-admin into a repo subproject of the Cluster Director daemon. There should be a set of common Jinja-based formatters for those common return types, but that's "bells-n-whistles" I will take care later. Right now a raw JSON dump is good 'nuff.
Update (15:20): Group photo taken, many refactorings, Zones management done. Time to write Node Controller.

[*]Write few nanostate scenarios to complete Node staging:[*]Reset/prepare PostgreSQL database[*]Prepare/mount distributed File System
NodeController is about to execute nanostates. It is like "nano-ansible" in the pocket, a fusion of Salt and Ansible ideas into a small package, which is not intended to be as broad CMS as those two. Essentially, it just runs a series of commands over SSH to a specific release of supported Cluster Node (AKA SUSE Manager) and does some rudimentary "things" on it, once it was installed and setup. These are like getting machine-id, backing up some configuration files, making standard operations with the database, start/stop/restart some services etc: all what can be done just via plain command line and mostly used for informational purposes.
This alone removes any kind of need of internal configuration management system to just stage a Cluster Node and add it to the swarm.
Day Three (Wednesday, 12 Feb)
An Unwanted Accident... (almost)
While working on a Cluster Node code for staging and playing with SSH sessions and channels, I just accidentally "rewrote" Salt, combining both best practices of Salt and Ansible. Of course, it is far-far-far-far away from what Salt can do today.
Or... is it? Let's see.
So the main plan was to manage cluster nodes and their components and nothing else. For that nobody needs a full-blown configuration management infrastructure, right? And so it happens that Cluster since has a Cluster Director (that supposed to scale-out on its own), but it is essentially just like that woulld be a Salt Master. And, consequently, since it is hooked up to an abstract Message Bus (you write an adapter connector for Kafka if you need many millions, but so far I am sure NATS will do for millions of #susemanagers), it talks to a Node Controllers on each #susemanager node, which is... right, an analogy to a Salt Minion. And here you go: bi-directional pub/sub that can perform something when a particular message arrives.
Security? Everything is happening over TLS anyway. But then another layer is based on pure OpenSSL: whatever Cluster Director needs to pass secretly to a specific Cluster Node, it sends to a channel, where every message is also encrypted on its own. Each Cluster Node is subscribed to a TWO channels:
- General public
- Private (by key fingerprint)
Cluster Director sends everything plain text to a public channel, but secret communication is running over private channel, encrypted with the public key of the recepient. Complexity of returners, pillars etc is no longer needed in this way.
It didn't took me long to craft a simple architecture to foresee even embedding Lua or Starlight into a state system. In fact, it would be even better than Salt, because one wouldn't have if/else imperative clutter in the declarative state (!). How a state looks like? Currently so (again, it is a hackweek of one solo "cowboy", not even pre-alpha):
id: some-test
description: This is a test state
state:
gather-machine-summary:
- shell:
- get-id: "cat /etc/machine-id"
- uptime: "uptime"
- hostname: "hostname"
The shell is a module I just wrote. It takes series of the commands and runs it, returning me something like this:
{
"get-id": "12e43783e54f25bb3f505cfeeff94045",
"upteime": "13:54:07 up 18:59, 1 user, load average: 0,10, 0,18, 0,17",
"hostname": "rabbit"
}
It also happens that all the above can be ran locally or remotely. Or one-to-many remotely over SSH.
But... Wait a sec. Only $SHELL? Can it do a bit more than this? Wait-wait. So if I can run arbitrary stuff already (which Ansible and Salt are anyway), then what stops me to call pure Ansible binary modules, and just access all that pile of crazy modules they've got already working? Nothing! Just scp them there and stockpile on the client. In fact, just install the entire Ansible and run it there as is. It is as same as Saltsible works, after all.
Basically, I ended up with a message-driven cluster architecture that happens to be compatible with Ansible modules. Kind of. Not yet completely, but to bring that to 100% compatibility is no brainer, just need few more extra days to get done. Which not my goal and priority at the moment anyway.
So and then imagine if having Lua or Starlight (Python dialect) embedded, you could do the above another way:
import:
- ssh_functions
id: some-test
description: This is a test state
state:
gather-machine-summary:
- shell:
- {get_id()}
- {get_uptime()}
- {get_hostname()}
These would be a functions somewhere in a file ssh_functions.lua. The same functions could do also this:
import:
- ssh_functions
id: some-test
description: This is a test state
state:
create-user:
- shell:
- {add_user(uid=get_salt_pillar("uid"))}
Well, you've got the idea. Anyway, I will focus on unchecked boxes above from yesterday and will finish this working at least anything. And thus won't extrapolate this up to eleven. At least not at the moment.
Update (17:40) Nanostates are happily running passed on scenarios on remote machines Sort of declarative orchestration. Not yet asynchronous. Few minutes left, maybe I will implement local runner?.. 
Update (somewhere evening) Refactored runners and implemented SSH runner as well as local runner. Nah, but the possibility of running Ansible modules FOR FREE is still bugging me! Instead of reimplementing PostgreSQL start/stop and prepare/mount distributed file system in a shell command line, how much time it will take to hook the whole Ansible modular system and use it from the nanostates? It is a Hackweek, after all! 
Day Four (Thursday, 13 Feb)
What one can do in basically four days, having almost nothing? A lot! 
So far, my leftovers from yesterday:
TODO:
[x]Integrate Ansible[x]Runs binary modules[x]Runs Python modules
[ ]Write few nanostate scenarios to complete Node staging:[ ]Reset/prepare PostgreSQL database[ ]Prepare/mount distributed File System
[ ]Cluster Node staging[ ]Integrate staging part together with the Node Controller
[ ]Node Controller (initial)[x]Configuration file[x]PostgreSQL event emitter[x]Events are emitted from an arbitrary SUSE Manager to the Cluster bus via Node Controller (simple-n-stupid PoC ATM)[ ]Commands from Cluster Directory received and mapped to the emitter facility (write one for XML-RPC APIs)
OK, well... Ansible would be certainly a right next step to look at, but ATM I'd rather save time and focus on emitting messages from the PostreSQL database, which is deep inside SUSE Manager's guts. So toss-in few basic shell commands for Node staging and that's it.
Update (12:00) SCNR...
Took this official Ansible module. Then wrote a nanostate snippet:
- ansible.helloworld:
name: "Cluster"
Result:
{
"Module": "ansible.helloworld",
"Errcode": 0,
"Errmsg": "",
"Response": [
{
"Host": "localhost",
"Response": {
"ansible.helloworld": {
"Stdout": "",
"Stderr": "",
"Errmsg": "",
"Errcode": 0,
"Json": {
"changed": false,
"failed": false,
"msg": "Hello, Cluster!"
}
}
}
}
]
}
Of course, this inherited Ansible's main illness: dont_run_this_twice.yaml. Calling nanostates nanostates is too loud at the moment: they won't check the state, but just fire whatever in them "into the woods". But the goal of the project nor to write another Configuration Management, n̶e̶i̶t̶h̶e̶r̶ ̶s̶c̶a̶l̶e̶-̶o̶u̶t̶ ̶A̶n̶s̶i̶b̶l̶e̶ (oops, that just happened unplanned), neither to fix Ansible imperative behaviour and build around it declarative runners (which is not really a problem, BTW).
Oh well. Fun. Now messaging bus story: Postgres, here I come!
Update (somewhere evening) PostgreSQL happily spitting out every changes to its tables through whatever way in Uyuni Server. The XML-RPC APIs are very slow, on the other hand. I was exploring ways how to implement plugins in Go, so then I don't have to bundle everything into one binary. The gRPC way is the only reliable and nicely decouple-able. The "native" Go plugins are an interesting tech preview, working nice (as long as the same $GOPATH and the same compiler is used) but sadly they seems still quite far away from production status. Plugins supposed to be written by different vendors, which is not the case right now seems to be supported.
I am right now solving problems how the Node Controller will reconcile network transaction across the entire cluster, making 100% sure all-or-none nodes has been updated. As always, there are several ways of doing it, but I have to find out which one suits best.
The Last Day of The Hackweek (Friday, 14 Feb)
At least it isn't Friday 13. Starting from touch main.go, so far what I've got per these days:
Someone Did It
But I chose it and put it together. I chose that, because I can also support it and bugfix it.
- Running equivalent to
etcd, which scales out way better thanetcd. Check out TiKV. If you know Rust, you will have lots of fun. - Running MySQL compatibility layer on top of it. Performance is about 10x times slower than MySQL's InnoDB, but in this case performance isn't an issue at all. Important that this thing scales out infinitely, just a bit of space hungry. Check out TiDB
- Running distributed storage and mountable filesystem. If SES guys will one day support "SUSE Manager on Ceph nodes", it will be just fantastic. Until then — other solutions. Check out SeaweedFS and IPFS. The IPFS is running Tumbleweed repo at SUSE.
- Running message bus that supposed to scale out same as Apache Kafka does. The reason not to use Apache Kafka is very trivial: its infrastructure is much harder to maintain. But this is not a reason and so hard infrastructure maintenance on its own does not rules Kafka out! You want it? No problemo: — just add another adapter to Apache Kafka and replace with currently used NATS. In fact, NATS perfectly co-exists with Kafka in some infrastructures. Check out NATS
I Did It
- Running Client System Daemon (i.e. "runs on registered client system") which main basic role to ask Cluster what node to use, automatically reconfigure Salt Minion and other configuration and then re-point client system to a new Cluster Node (AKA Uyuni Server), if that is needed. It also recovers client system back to the cluster, once Cluster Node puffed in smokes.
- "one to many and many to one" API Gateway, which allows
spacecmdand similar tools to "just work" across multiple nodes. Granted, it wasn't written during this Hackweek and is 99.999% compatible (I was too lazy to get back and implement overloaded XML-RPC signatures for REST, as well I am returningnilinstead of an empty dictionary — probably a bug, but... meh... later). This thing also runs Swagger UI for OpenAPI specs against all XML-RPC API for SUSE Manager. - Very basic Cluster Director that can manage zones in and add cluster nodes. It as well runs OpenAPI/Swagger UI. Very basic, because it has no features yet. But doesn't mean it doesn't have more-less solid architecture.
- Library that runs Ansible in Salt fashion (via bi-directional pub/sub, which rules out returners/pillars as unnecessary). I am going to use that internally instead of both Salt and Ansible on their own. Again, it is simpler to call Ansible module reusing existing scaled out infrastructure, rather then run-and-take-care-of yet another components. And I don't have to maintain Ansible: it is perfectly tested anyway.
- Library that resembles SaltSSH by running Ansible modules (both Python and binary). I am considering I've done it, because I could (doesn't mean I should).
- Very unfinished Initial Node Controller Daemon, which listens to Uyuni Server events and emits messages to the bus for further operations.
Phew. Not bad as for basically four days, I'd say! All that stuff I wrote in Go. I'd say it does make sense to use that language, if you don't want to write Java or Python.
What are my nearest plans?
- Finish the "loop" and have all components running, talking to each other, client nodes are transfered seamlessly.
- Achieve network transaction on updating Cluster Nodes.
- Write some Ansible modules, likely in plain old C and Rust, add their caching on the client so it will perform well, add seamless module updates. Generic Ansible doesn't hurt, but I don't need it for Cluster needs.
- Modular/pluggable system in Go, so this whole project can be adaptable to other products, not just SUSE Manager.
Presentation Slides
I've put an outline together all that into my Google Drive. Enjoy.
...and stay tuned

Save pytorch models in OCI registries by jguilhermevanz
Description
A prerequisite for running applications in a cloud environment is the presence of a container registry. Another common scenario is users performing machine learning workloads in such environments. However, these types of workloads require dedicated infrastructure to run properly. We can leverage these two facts to help users save resources by storing their machine learning models in OCI registries, similar to how we handle some WebAssembly modules. This approach will save users the resources typically required for a machine learning model repository for the applications they need to run.
Goals
Allow PyTorch users to save and load machine learning models in OCI registries.

Mortgage Plan Analyzer by RMestre
https://github.com/rjpmestre/mortgage-plan-analyzer
Project Description
Many people face challenges when trying to renegotiate their mortgages with different banks. They receive offers from multiple lenders and struggle to compare them effectively. Each proposal may have slightly different terms and data presentation, making it hard to make informed decisions. Additionally, understanding the impact of various taxes and variables can be complex. The Mortgage Plan Analyzer project aims to address these issues.
Project Overview:
The Mortgage Plan Analyzer is a web-based tool built using PHP, Laravel, Livewire, and AdminLTE/bootstrap. It provides a user-friendly platform for individuals to input basic specifications about their mortgage, adjust taxes and variables, and obtain short-term projections for each proposal. Users can also compare multiple mortgage offers side by side, enabling them to make informed decisions about their mortgage renegotiation.
Why Start This Project:
I found myself in this position and most tools I found around are either for marketing/selling purposes or not flexible enough. As i was starting getting lost in a jungle of spreadsheets i thought I could just create a tool to help me and others that may be experiencing the same struggles to provide clarity and transparency in the decision-making process.
Hackweek 25 ideas (to refine still :) )

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.

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.

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.

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.

suse-rancher-supportconfig by eminguez
Description
Update: Live at https://github.com/e-minguez/suse-rancher-supportconfig
I finally didn't used golang but used gum instead
SUSE's supportconfig support tool collects data from the SUSE Operating system. Rancher's rancher2_logs_collector.sh support tool does the same for RKE2/K3s.
Wouldn't be nice to have a way to run both and collect all data for SUSE based RKE2/K3s clusters? Wouldn't be even better with a fancy TUI tool like bubbletea?
Ideally the output should be an html page where you can see the logs/data directly from the browser.
Goals
- Familiarize myself with both
supportconfigandrancher2_logs_collector.shtools - Refresh my golang knowledge
- Have something that works at the end of the hackweek ("works" may vary )
- Be better in naming things

- 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
Goals for HackWeek 2024
- Add support for ClusterClass
- Add e2e testing
- Add more Unit Tests
- Improve Status Conditions to reflect current state of Infrastructure
- Improve CI (some bugs for release creation)
- Testing with newer Harvester version (v1.3.X and v1.4.X)
- Due to the length and complexity of the templates, maybe package some of them as Helm Charts.
- Other improvement suggestions are welcome!
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
Thanks to @isim and Dominic Giebert for their contributions!

Looking for help from anyone interested in Cluster API (CAPI) or who wants to learn more about Harvester.
This will be an infrastructure provider for Cluster API. Some background reading for the CAPI aspect:
- Cluster infrastructure provider contract
- Machine infrastructure provider contract
- Provider implementers guide
SMB3 Server written entirely in Rust by dmulder
Description
Given the number of bugs frequently discovered in the Samba code caused by memory issues, it makes sense to re-write the smbd service purely in Rust code. Meanwhile, it would be wise to abandon backwards compatibility here with insecure protocol versions, and simply implement the SMB3 spec.
Goals
Get a simple server up and running and get it merged into upstream Samba (which now has Rust build support).

Grapesss: a physical Shamir's Secret Sharing application [ESP32-C3 + Mobile] by ecandino
Description
A couple of years ago I created StegoSecretS, a small cli used to encrypt and split a secret into multiple keys, using the Shamir's Secret Sharing algorithm.
The idea is to re-implement the project using physical devices. One device alone will be useless, but when close together they can be used to decrypt the secret.
On a practical side the user encrypts the secret with a mobile application. The same application is used to split the secret, and load the partial keys into different micro-controllers. Another user will be able to decrypt the secret only having at least N devices close together (using the application).
I'm planning to use a couple of ESP32-C3 I bought, and build a very simple Android mobile application.
Goals
- Learn about Rust and micro-controllers (ESP32-C3)
- Learn about mobile applications (Android and Kotlin)

Kanidm: A safe and modern IDM system by firstyear
Kanidm is an IDM system written in Rust for modern systems authentication. The github repo has a detailed "getting started" on the readme.
In addition Kanidm has spawn a number of adjacent projects in the Rust ecosystem such as LDAP, Kerberos, Webauthn, and cryptography libraries.
In this hack week, we'll be working on Quokca, a certificate authority that supports PKCS11/TPM storage of keys, issuance of PIV certificates, and ACME without the feature gatekeeping implemented by other CA's like smallstep.
For anyone who wants to participate in Kanidm, we have documentation and developer guides which can help.
I'm happy to help and share more, so please get in touch!
Better diff'ing experience by MSirringhaus
Description
For diff-ing directories, I usually like to use meld, but it struggles a lot with large trees. Experiment with writing a TUI meld-clone for diffing directories and files
Goals
Get first prototype going of a TUI that can show
- diffs of text-files
- diffs of directories.
Stretch goals
- Themes
- Filters (no whitespace, etc.)
- Live config changes (Show/hide line numbers, etc.)
