🚨 Contribfest: Contribution Guide and Workshop: Help Us Improve the Prometheus Ecosystem!

Wednesday April 2, 2025 11:15 - 12:30 BST

Level 3 | ICC Capital Suite 17

Have you ever wondered how to introduce that quick fix you always wanted to do to Prometheus or Alertamanger server? What about proposing bigger changes to Prometheus like improving TSDB storage, API or Prometheus standards likePromQL, OpenMetrics or Remote Write?

It might be easier than you thought! In this workshop, we will, together, propose an example (or yours!) code change to Prometheus! The participants will learn and exercise:
How to find various code components in the Go codebases for Prometheus and auxiliary projects like Alertmanager, avalanche, etc.
Proposing the bigger changes through the Prometheus proposal process.
Testing and benchmarking Prometheus.
Documenting changes.
What it takes to become a maintainer one day!

Prerequisites for the active participation: Linux or Mac dev machine, git and Go 1.23 installed.

🚨 Contribfest: Extending Image Based Systems Using Systemd System Extensions

Wednesday April 2, 2025 14:30 - 15:45 BST

Level 3 | ICC Capital Suite 17

On general purpose image based systems such as Flatcar and Bootable Containers, users are encouraged to run all their applications using containers. To make updates safe and predictable, the system is mounted as read only and local modifications are discouraged.

While containers offer a lot of flexibility on Linux, there are still cases where installing binaries or running applications directly on the host operating system is preferred.

As a trade-off, Systemd's system extensions (sysexts) provide a mechanism to extend host's content while preserving the safety guarentees around updates. Some image based OS like Flatcar, Fedora CoreOS or Atomic Desktops are leveraging sysext images to provide container runtimes.

In this tutorial, Timothée and Mathieu will give you the fundamentals of sysexts to help you building, running and updating your very first sysext images. From simple sysext-images like Containerd to more complex ones: learn how to securely extend image based systems.

🚨 Contribfest: Expanding the Helm Ecosystem With Helm 4

Wednesday April 2, 2025 16:15 - 17:30 BST

Level 3 | ICC Capital Suite 17

Are you passionate about Helm and looking for ways to contribute? Join Helm maintainers at this ContribFest to help shape the future of the project and its ecosystem! This session focuses on three exciting initiatives:

**Exploring the Helm Ecosystem:** From Chart Testing to Chart Releaser, Chart Museum, docs, and traditional plugins, discover how these projects support end-user workflows and where your skills can fit in.

**Building a Triage Team:** Helm’s biggest bottleneck is issue and PR triage. Learn how to make an immediate impact here—contributors who excel and commit time can be nominated as Triage Maintainers.

**Diving into Helm 4:** Helm 4 is on the horizon, with a revamped architecture and an expanded plugin system. Explore how to contribute plugins, ideas, and code to shape this new era.

Whether new to Helm or experienced, this session is your chance to connect, learn, and make a difference. Let’s build Helm’s future together!

🚨 Contribfest: Kubernetes Observability Simplified: Build, Debug & Monitor With Inspektor Gadget

Thursday April 3, 2025 14:15 - 15:30 BST

Level 3 | ICC Capital Suite 17

Join us for an interactive session exploring Kubernetes observability and debugging with Inspektor Gadget! This powerful project combines eBPF tools and a systems inspection framework tailored for Kubernetes, containers, and Linux hosts.

The session kicks off with an introduction to Inspektor Gadget, followed by hands-on guidance to set up your development environment (we’ll do most of the heavy lifting for you ahead of time). Participants will learn about the concept of "gadgets" and create their own simple "Hello World" gadget. From there, you can explore various ways to contribute:

- Develop new gadgets for emerging use cases.
- Enhance existing gadgets with additional capabilities.
- Collaborate on brainstorming innovative features.

Whether you’re looking to use Inspektor Gadget for debugging or dive deeper into creating gadgets, this session has something for everyone.

🚨 Contribfest: Making SlimToolkit Extensible: Introducing WASM-based Plugins for XRAY Container Image Scanning

Thursday April 3, 2025 16:00 - 17:15 BST

Level 3 | ICC Capital Suite 17

The ability to contribute to the project has been limited by the need to understand the project code base. Introducing plugins in the project will make it possible for new contributors to extend the project without understanding the entire project.

The XRAY command in the project is used to scan container images to extract useful container insights. It's a great place to introduce plugins because there's always more to analyze. It will also make it easier to integrate with other CNCF projects to provide additional analysis capabilities and to provide valuable data for those projects.

There are different plugin designs with each own set of pros and cons. A WASM-based plugin system will make it possible to create plugins in different languages contributors are more familiar with and it won't be limited to people who know Go.

No low level SlimToolkit, container tech or WASM expertise is required. You only need basic Go and interest in learning WASM libraries (e.g, Wazero, Extism, waPC)

Friday April 4, 2025 11:00 - 12:15 BST

Level 3 | ICC Capital Suite 17

PipeCD is fast approaching the v1 milestone with significant performance improvements and support for unlimited platform deployment with the pluggable architecture in Piped. Users now have the flexibility to develop stages and plugins for application types specific to the platforms they are utilizing.

During this session, we will focus on reviewing the interface of Piped for the pluggable architecture and demonstrate how to create a simple plugin. Attendees can build a simple plugin that only includes the QuickSync stage for their application's platform use.

In addition, we have prepared many good-first-issues so that participants can get acquainted with the PipeCD project and understand how PipeCD is used to achieve progressive delivery quickly and effectively.
