  Contributing to Jenkins, CDF and Google Summer of Code

  

  YouTubeSpeaker Deck

  Jenkins is a very diverse project with many opportunities to contribute and many technology stacks. Some examples: Java, JavaScript, Golang, Groovy, Docker, Kubernetes. And it is not only about code. We are also continuously looking for non-code contributions: documentation, testing, design, and spreading the word. We always welcome experienced and newcomer contributors to join the community.

  This presentations is an introduction to contributing to Jenkins, from code and testing to documentation and community outreach. The presentation also covers Google Summer of Code and other opportunities for newcomers to get involved.

  Presented by Oleg Nenashev, Mark Waite, Shivay Lamba, and other community members.

  Guerilla Developer Relations. How to start DevRel and turn around the culture in a legacy enterprise company?

  

  Speaker Deck

  Many developers care about the end-user experience, especially when those end users are fellow developers. But do their companies really care? Despite the product-led growth buzz, not everyone has a DevRel strategy beyond slides. “Top-to-bottom sales for the win,” “Let’s work with VPs,” they say. Can a single contributor turn around the culture and introduce developer relations in a big company? Maybe! Can they burn out in the process? Well, let's talk...

  We'll talk about setting up developer relations and an open communications culture in a rigid enterprise environment. How to get started without any resources? How to find allies and avoid making foes? What could possibly go right (sic!)? And how to actually make a difference and prove it? What is InnerSource, and how is it even related to this talk?

  Mentorship programs for students in open source. Industry/Academia Partnerships

  

  Speaker Deck

  Mentorship and outreach programs are often considered side projects in both academia and the industry. Although they are a nice way to spend time and have some fun, one may say they rarely add new long-term contributors to a company project or a community, and that they are not always beneficial to students, especially on the Master and PhD level. Is this true?

  Let's talk about organizing mentorship programs in partnership between open source projects and universities. How such contributions help to grow your current community and contributors. How to involve students and higher education orgs into wider community efforts? And what can they get from it? Let's talk about various program types: from wide outreach programs like GSoC, individual mentorship programs or wide-reach programs like Hacktoberfest that can be leveraged by researchers. I will share some examples from my open source projects and Swiss universities, for example GSoC in the Free and Open Source Silicon foundation together with ETH Zurich.

  Mentorship programs. Growing new team and community leaders

  

  SessionizeYouTubeSpeaker Deck

  Mentorship and outreach programs are often considered as side projects. Although they are a nice way to spend time and have fun, one may say they rarely add new long-term contributors to your company project or community. Is it true? Is it even the main goal? Or is it about team bonding and growing new maintainers and community leaders?

  Let’s discuss how to organize mentorship programs that help grow your current community and contributors. How do we involve a contributor in broader community efforts? How do we help them grow and take on new roles? Let’s discuss various program types, including wide outreach programs such as GSoC or Hacktoberfest, newcomer assistance, focused maintainer mentoring programs, and individual leadership training like shadow officers.

  The talk is based on my experience in the Jenkins, FOSSi, the Continuous Delivery Foundation and other communities. I organized or helped to organize several mentorship and outreach programs: contributor/maintainer onboarding, GSoC/GSoD, Outreachy, CommunityBridge, various hackathons, and board member training.

  Open roadmaps for your open communities. Not a success story, but you may have one

  

  SessionizeYouTubeSpeaker Deck #1Speaker Deck #2

  As open source projects and communities grow, it becomes difficult to understand what’s going on inside. A public and up-to-date roadmap can encourage new contributors to join the project and guide the efforts of existing contributors, and also give confidence to adopters about the direction and sustainability of the projects. Is it easy to create a public roadmap? Probably. Is it easy to maintain it? Not exactly. Did we fail with it? Yes.

  Oleg will share the experiences of public roadmaps in the projects he has contributed to: Jenkins, WireMock, Keptn, CDF, etc. He'll share the reasons and principles that have guided creation of open roadmaps, the challenges encountered, the techniques and technologies that could be used in your projects. We’ll talk about maintaining roadmaps, mistakes we made there and how we addressed them.

  In particular, Oleg will describe building a roadmap with help of GitHub Projects and modern features offered by the GitHub ecosystem. That could be the easiest way for new projects and communities, and can be also useful for established projects.

  The Ignite version is a short introduction with several tips about building an effective public roadmap for your project.

  Bottom-up AI enablement while improving DevEx and collaboration

  Many developers care about collaboration, AI enablement, and developer productivity. But do their companies really care? Despite the endless DevOps and developer productivity slide decks, not everyone has a strategy beyond “let’s buy a ChatGPT subscription and call us AI-first” or a classic “let’s have another weekly meeting” from management. Can a single engineer actually introduce InnerSource and get nice things tools to teams in a big enterprise? Maybe!

  We’ll discuss setting up InnerSource and an open contribution culture inside rigid corporate structures that are not willing to change. We all try to change companies first, and in 2025-2026, the ongoing AI hype can be a great leverage - a universal justification to form internal guilds, secure funding, and get executive attention for collaboration and productivity initiatives.

  How to get started without a budget or official blessing? How to find allies and not burn too many bridges? What could possibly go right (sic!)? And how to show impact when everyone’s so obsessed with KPIs?

  d'AIrtagnan and Three Mocketeers for easy integration testing - all as one, and one as all

  Sessionize

  When you model (aka "mock") services during software development or integration testing, you need to mimic APIs, databases, and other data providers. You can't do this with just one tool; you need to combine several. You will also need zillions of configuration files and test samples for mocks... unless you leverage the power of Generative AI. Can we make it hallucinate productively without breaking the vibe of actual development?

  In this live session, I'll show you how to create test services, mock databases, and API providers using Testcontainers, Microcks, and DataFaker for a modern Android/Gradle project. After the introduction, we'll skip all the boring YAML configurations and go straight to leveraging AI and MCPs to generate proper data services and mocks with minimal effort from the developer's side.

  Gradle Build Tool for Agentic World, NOW!

  The way we build software is changing, and agents are rising! CI systems have already evolved from brittle shell-script runners to highly resilient, feature-rich services that support developers at every step, from a new branch in the IDE to deployment. The same happens with build tools. In five years, we won’t be running mvn clean package or gradle build. Instead, developers or AI agents will interact with build servers in dialog mode. So, bye-bye “software builds” and welcome “software transforms” powered by build servers?

  This talk introduces the great old Gradle Build Tool but re-packaged for the new world where developers don’t just write tasks—they collaborate with the build server directly, or let their agentic system do that. We’ll explore how Gradle’s existing capabilities—its Daemon Mode, advanced build and configuration caching, Tooling API, Build Server Protocol integrations, MCP servers & Co make it not just a Build Tool, but a Build Server suitable for iterative agentic development!

  You’ll see live examples of agentic workflows in action, including conversational build interactions from within IDEs like Visual Studio Code or IntelliJ IDEA, interactive dependency updates and toolchain management. Everything I present will be open source and ready for tinkering in your projects.

  Advanced Code Coverage with Jenkins and API Mocking

  

  SessionizeYouTubeSpeaker Deck

  In 2015-2018, I talked about how to use the Jenkins Pipeline and custom libraries to do advanced integration tests and analyze code coverage. Coverage plugins were rather weak, and one needed some scripts and hacks to make it work, and to DIY for distributed testing. In 2021 the situation has changed significantly thanks to the Coverage and Checks API plugins. Distributed integration testing also became easier thanks to better coverage collectors and integrations with API mocking tools. So, good time to be alive… and use Jenkins!

  We will talk about how modern Jenkins allows you to improve and analyze code coverage. We will talk about unit and integration testing with WireMock, the new Coverage Plugin, support for standard formats (Cobertura, JaCoCo, gcov, JUnit, etc.), parallelization for heavy integration tests and API mocking, and integration with GitHub Checks API. How can you analyze code coverage in Jenkins and when do you need to create your own libraries? And what’s the fuzz about Testcontainers and WireMock for integration testing?

  Fake it until you `make it`. API integration testing with Testcontainers and WireMock

  

  SessionizeYouTubeSpeaker Deck #1Speaker Deck #2

  Testcontainers has become one of the most popular tools for software integration testing. If you can put your system-under-test into a container, Docker compose cluster or a pod, this is what you're likely to use. If your target isn't ready, not containerizable or just too heavy for testing as is, you can always use mock testing frameworks, e.g. WireMock or MockServer in the JVM ecosystem. Can you combine both approaches? Sure!

  In this talk, we will classify integration testing and discuss application areas for WireMock and Testcontainers, and discuss which tool to choose for each use-case. And why not both? We will discuss putting WireMock into Testcontainers, and getting the best from their features thanks to the new WireMock modules for Testcontainers. Last but not least, we will see how to put WireMock in front of the Testcontainers or your real system to do deeper tests or even chaos engineering.

  P.S: We will focus on the Java, Golang or Rust examples, but the same approaches can be used everywhere

If your target isn't ready, not containerizable or just too heavy for testing as is, you can always use API mocking like WireMock to mock your interfaces including REST API, gRPC, etc. But are these tools available to C/C++ developers? And the answer is YES!

  In September 2023 I created Testcontainers for C/C++. This is not a standalone Testcontainers engine, but a C-style shared library adapter for native languages like C/C++, and also D, Lua, Swift, etc. It is a MVP SDK that can be later extended for the languages. The project is based on Testcontainers for Go which is one of the most powerful Testcontainers implementations. And yes happy to chat about how it does [and doesn’t] work under the hood.

  The objective of this talk is to present the existing solution, find early adopters and get feedback from professional C/C++ developers who use modern C/C++. For me it has been 10 years since I used it professionally for Embedded and SCADA projects, so it would be awesome to get the community feedback on use-cases and priorities!

  Want a cup of Java? API and data mocking for Python projects

  

  SessionizeSpeaker Deck

  When working in embedded and observability domains, I’ve used Python scripting to retrieve and pre-process data from external sources, and one of the issues I’ve seen is the difficulty to reliably test data pipelines against external services: API limits and pay-per-use costs, service outages, etc, etc. So, can we model (aka “mock”) the services to reliably test our data ingestion pipelines?. Sure we can!

  In this talk I will show a few ways to build test services, databases and API providers with the help of Testcontainers and WireMock available on Python, thanks to container tech. Then, we will extend the approach by adding the generation of fake data with help of Faker libraries or Synthesized that can be used for both relational data and data sequences.

  Distributed and microservice architectures are all about APIs these days, whether you use gRPC, REST API, Websockets or any other interface. There are tools for integration testing that involve API providers, including mocking them based on OpenAPI specifications. There are even Kubernetes native tools like Microcks that are scalable and provide valuable features and observability out of the box. More classic tools, including my favorite WireMock, are available on Kubernetes too.

  If you’ve ever developed for JVM or .NET stacks, most likely you’ve heard about WireMock. It is a popular open-source tool and framework for API mock testing, with over 5 million downloads per month. It has implementations and adapters for many languages.

  In this talk, I will focus on using WireMock for testing Cloud Native applications in Kubernetes, including using it for common continuous delivery and deployment use-cases. We will see how to use WireMock as a standalone deployment, or as a part of Argo CD and Tekton pipelines. I’ll also show how these approaches can be integrated with WireMock Cloud for those who want to do distributed testing and chaos engineering.

  Speaker Deck

  How do Open Source and DevOps cultures impact Continuous Integration (and maybe not CD for once)? "Open source is eating the world". The same happens with the automation tools domain, including CI. There are many open source CI tools or open ecosystems on the market: Jenkins, Dagger, Argo projects, GitLab CI, Tekton, Dagger, GitHub Actions, etc., etc. There are many generations of these tools, with their architectures and use cases. We will talk about these tools and their evolution, from monolith services to cloud-native CI and Linux-way split to building blocks and interoperability.

  What changed since CI was introduced 20 years ago? How do Open Source, InnerSource, and DevOps impact the landscape? What's next for the tools: cloud-native environments, machine learning, etc.? And how do open source foundations and other collaborations participate in the evolution of open source tools and facilitate it?

  Jenkins is one of the leading open-source automation servers. It’s a framework, which can be adjusted to a particular area with help of its flexibility and plugin system. Many open-source hardware and embedded projects build their Continuous Integration and Delivery flows with Jenkins, because there is not so many tools in the area.

  In the talk I would like to cover common use-cases of Jenkins in hardware projects like integration with EDA tools and hardware peripherals like FPGAs and reporting of build, test and coverage reports. After that I’ll share one of two case studies about integration of Jenkins into hardware projects. If I achieve something presentable with the ongoing project by the conference, one of the case studies will be about FuseSoC integration with Jenkins.

  Cloud Friendly(?) Jenkins. How we failed to make Jenkins cloud native and what we learned

  

  SessionizeSpeaker Deck

  Key takeaway: Being Cloud Friendly is a must, Cloud Native is optional. Likely YAGNI in your projects

  Jenkins has been one of the most popular automation servers in the world. It is widely used for CI/CD purposes in cloud environments. You may have heard that Jenkins is not cloud native, and of course it is true. You may have heard that Jenkins controllers are a legacy monolith from the 2000s. That is not true, it is quite cloud friendly if used right. And yes we tried to make Jenkins cloud native, but it didn’t quite work. Why?

  I have been involved in Jenkins architecture projects for more than ten years, including pluggable storage, multi-tenant Jenkins, cloud-native agents, breaking down the controller monolith, Kubernetes integrations, etc. Some of these efforts worked, some didn’t. But it was a great learning experience that can be used by developers and maintainers of other projects that consider re-platforming them to make cloud- and Kubernetes-native. I'll talk about the technical assumptions and mistakes we made in Jenkins, and how it worked. What to keep in mind when doing the re-platforming? And do you even need it?

  Common Pitfalls in Jenkins Security and How to Avoid Them

  

  YouTubeSpeaker Deck

  It is 2025, and Jenkins, an open source automation server with 20 years of history, still dominates the CI/CD market and remains a mission-critical part of the worldwide software supply chain. In 2025, it even won the "The most innovative DevOps open source project" award from DevOps Dozen, and got security grants from Alpha Omega. But Jenkins still has quite an old architecture, and one can consider it a remote execution engine which has access to project data… by design. So, how secure is your instance and supply chain when using Jenkins?

  When it comes to Jenkins instances with thousands of users, it is hard to retain status quo between security itself and its impact on user experience due to the restrictions and performance degradation. I will talk about Jenkins security model, best practices and common non-newbie configuration mistakes which we often see on production instances. In particular we will discuss Groovy scripting, controller-to-agent communications and resource isolation. We will also review a few supply chain attack cases that happened through Jenkins, and how one could prevent them.

  This presentation summarizes results of our project from the Jenkins World 2016 hackathon. The prototype implements reporting of build logs to Logstash/Elasticsearch instead of the system disk and their further visualization within the Jenkins Web UI.

  The approach allows to reduce network and IO load on Jenkins master and thus avoid performance bottlenecks on large-scale instances.

  Jenkins 2022 and Beyond

  

  YouTubeSpeaker Deck

  Is the Butler Still Young? Maybe not but it is still one of the most popular automation tools. Jenkins in 2022 is not Jenkins in 2012. It keeps evolving to address demands from its users and contributors: pipeline as code, configuration as code, better support for cloud environments, UX, etc. We are looking forward to the next major iteration in Jenkins evolution. So what’s next for it? I will focus on the current challenges for Jenkins. What does need to change in the project and the community to keep it relevant? We will talk about revitalizing the community and attracting new company contributors, consolidating user experiences, and reusing experiences of BlueOcean and Jenkins X? We will also talk about interoperability with other projects, making Tekton a first class citizen Pipeline engine, and making Jenkins available everywhere regardless of CI/CD system you actually use.

  Jenkins Remoting. Dealing with agent connectivity issues

  

  Speaker Deck

  Welcome to the Dark side of Jenkins...

  Almost all agent types in Jenkins use the Remoting library to communicate with the master, including JNLP and SSH agents. Although Jenkins’ ability to run tasks on multiple hosts is one of its success factors, agent connection stability is known to be a major pain point in large-scale installations. In this workshop, the talk is about remoting internals, how to diagnose issues, how to configure Jenkins and underlying infrastructure, and the future of this layer in Jenkins.

  Leap from Java 8 to Java 11 in Jenkins. Our *.war story

  

  Speaker Deck

  Jenkins, one of the leading open-source automation servers, has not been supporting Java 9 and above since its official release. Over the last year Jenkins contributors were working towards the support of Java 11 (Jenkins JEP-211). Jenkins has a huge and sometimes legacy Java/Groovy/native codebase, includes DSL engines, and depends on many upstream libraries and modules (including ones deleted from Java 11). It was a thorny way, but Java 11 support is almost ready to be released.

  In this talk I would like to share our experiences and talk about potential obstacles others may hit while implementing Java 11 support in their projects. What issues have we hit while implementing support of Java 11 in the core? Are modules and deprecations that tricky for a web application (spoiler: no)? How have we enabled building and testing with OpenJDK 11 in our Maven-based pipelines? And how have we retained Java 8 compatibility after all these changes?

  Managing Embedded System test infrastructures with Docker and Jenkins

  

  Speaker Deck

  Virtualization and Containerization are one of the hottest areas in the test automation of software systems.

  Such approaches simplify management of test environments, reduce costs and improve reproducibility of tests.

  Docker is one of the popular container platforms in the area.

  Are such approaches applicable to the Embedded Systems area?

  Container technologies have limitations, especially when it comes to tests involving hardware-in-the-loop (HWIL) in the loop or drivers.

  In test automation flows it is important to know Docker limitations to properly combine it with other approaches.

  This talk focuses on Docker usage specifics in simulation-based and HWIL test automation with Docker and automation servers like Jenkins.

  The talk includes overview of Docker advantages and disadvantages, and provides examples from real-world projects.

  Main takeaways from the talk are the recommendations when and how to use Docker in Embedded Systems testing.

  And how to migrate the automation flows to such new approaches.

  Under the hood of serverless Jenkins. Jenkinsfile Runner

  

  Speaker Deck

  There were significant changes in the Jenkins project over last year. It is still one of the most popular automation servers in the world, but it is not just a “server” anymore. In 2019 Jenkins is a universal automation engine, which actively evolves towards the new Cloud Native architecture and which can be used in any CI/CD flows. It can be used not only as a server, but also as a “serverless” single-shot execution. And it is not only about Jenkins X, but also about more classic usages.

  In my talk I will present Jenkinsfile Runner - an engine which allows running Jenkins Pipelines in a single-shot container. I will show how it is used in Jenkins X, GitHub Actions and other services. And, finally, I will show how to package your own Jenkinsfile Runner images and run it in any environments, CI systems and Cloud providers.

  FOSDEM 2024 - Jenkinsfile Runner Update

  

  Speaker Deck

  Jenkinsfile Runner update at the Jenkins Contributor Summit. TL;DR: No big updates, I am still on a break in the Jenkins project, and I have only some time to keep the lights on. I am looking for co-maintainers and tinkerers who are interested in working on the project but it still remains relevant.

  One thing to mention is that I no longer consider JFR relevant for integration testing of Jenkins Pipelines. At this stage, it can be totally replaced by the containerized Jenkins instances running inside Testcontainers, because it provides all features of the real Jenkins like classloading, even with an embedded K3s cluster if you need it for testing. Container suspension and caching address performance concerns for tests. Recently Steve Hill created a module for it.

  Well-functioning continuous integration, delivery, and deployment pipelines are important to the stability of cloud-native applications, including recovery when things go wrong. CI/CD observability is therefore an important complement to observability in production environments.

  This talk explores a modern Java stack using Quarkus, Java Flight Recorder, build tools, and delivery systems such as Dagger and Argo CD. It demonstrates OpenTelemetry, Prometheus, and Jaeger, with approaches that can also be applied to other OpenTelemetry collectors.

  Les objectifs de niveau de service (a.k.a Service Level Objectives - SLO) sont un élément clé des pratiques modernes d'ingénierie logicielle. Ils permettent de quantifier la qualité du service fourni aux utilisateurs finaux, et leur maintien devient donc important pour les approches DevOps modernes avec une livraison progressive. Dans cette démo, nous montrerons comment utiliser Keptn pour tirer parti de votre surveillance existante avec Prometheus afin que vous puissiez visualiser les SLO pour les principales parties prenantes et automatiser leur action.

  Qu'est-ce que Keptn? En un mot, il s'agit d'un plan de contrôle piloté par les événements pour l'orchestration des applications natives du cloud. Il permet de nombreux cas d'utilisation, y compris, mais sans s'y limiter, les opérations basées sur les SLO, l'observabilité, les alertes et la correction. C'est un projet sandbox au CNCF, et il a demandé le statut d'incubateur.

  Moonwalk the OpenAPI talk. Developer experience and OpenAPI 4

  Speaker Deck

  Swagger and OpenAPI revolutionized the API landscape and created a thriving ecosystem of developer tools, from IDEs to contract testing and no-code solutions. In our projects (WireMock, Jenkins, Testcontainers, and WireMock Cloud) we adopted OpenAPI to provide a great developer experience including automated generation of plugins, pipeline integrations, and the creation of Mock APIs directly from OpenAPI definitions. Not everything went well. OpenAPI excels at documentation but not so much for machine processing. We had to craft our own tooling, apply some AI magic to reverse engineer specifications, and build behavioral models. Most of it could have been prevented if OpenAPI v3 was more flexible and extensible.

  In this talk we will discuss using OpenAPI for service modeling, also known as "mocking" and its impact on developer experience. Then, we will discuss the current limitations of OpenAPI 3 and offer a glimpse into the anticipated enhancements in OpenAPI v4 "Moonwalk," which are to be released soon.

  Swagger and OpenAPI revolutionized the API landscape and created a thriving ecosystem of developer tools, from IDEs to contract testing and no-code solutions. In our projects (WireMock, Jenkins, Testcontainers and WireMock Cloud) we adopted OpenAPI to provide a great developer, and achieved great results. At the same time, the v3 version of specification has too many limitations, especially when it comes to behavior modeling: limited extensions framework, poor response flexibility limiting complex API options, and weak examples and self documentation capabilities. Good news is that OpenAPI v4 (Project Moonwalk) addresses many of those concerns and, hopefully, could address others before the release. Let’s, wearing our end user hats, discuss the v3 experiences and how we could address them in the upcoming major release!

  Cloud and Hybrid Developer Environments - how virtualization transforms your IDEs for embedded projects

  

  Speaker Deck

  Back in 2017 at QA&Test Bilbao, I explored how Docker and Jenkins pipelines could transform CI/CD for embedded projects. Fast forward to 2023, containerization has become the norm in embedded software QA. My recent talk focused on tools like Testcontainers and WireMock, now widely used for testing not just backend services but entire embedded systems—from SCADA to IoT—within virtualized environments powered by Kubernetes. These technologies now form the backbone of modern testing infrastructure in software, and now expand to edge and embedded systems to cover full-system virtualization and integration testing. Same happens on the developer machines.

  Embedded QA Engineers are entering a new era of development enabled by Cloud Development Environments (CDEs) like GitHub Codespaces or Devcontainers, where fully configured workspaces can run on laptops, Kubernetes clusters or public clouds. Containers and VMs, often managed with tools like KubeVirt and QEMU, and wrapped by frameworks like Testcontainers, enable scalable, hardware-aware test setups that support HIL testing, firmware validation, and system modeling. It might sound like a miracle, but it's actually possible with modern tech stacks!

  This talk demonstrates how to build such "hybrid developer environments" entirely with open source tools, combining C++/SystemVerilog development, embedded hardware access, and even AI-driven test automation – showing that the modern IDE for embedded QA is now distributed, intelligent, and platform-agnostic.

  Contributing to Open Hardware with FOSSi Foundation

  

  Speaker Deck

  TL;DR: You don't have to be a hardware engineer to help build the future of Open Hardware and EDA.

  Open Hardware is much more than designing chips and circuit boards, and you don't need to be a hardware engineer to contribute!

  In this talk, we explore the Open Source Hardware (OSHW) ecosystem, from digital hardware designs and RISC-V to development tools, automation, documentation, and community building. We introduce the FOSSi Foundation, LibreCores, and other initiatives that make open hardware accessible to contributors of all backgrounds.

  We'll also discuss how to discover projects, get involved in communities, and find opportunities through programs like Google Summer of Code. Whether you're a software developer, student, hardware enthusiast, or newcomer to open source, there is a place for you in the Open Hardware community!

  Key Takeaways

  • Anyone can contribute. Hardware engineering experience is not a prerequisite.
  • Open Hardware is more than hardware. Contributions include software development, CI/CD, simulation, documentation, design, and community outreach.
  • Start small. Find projects matching your interests, follow contributor guidelines, and ask communities for help.
  • Explore the ecosystem. FOSSi Foundation, LibreCores, OpenCores, and other communities provide opportunities to get involved.
  • Keep learning and have fun! Open Hardware offers valuable opportunities for learning, collaboration, and career development.

  OpenFeature - making feature flags a commodity

  

  YouTubeSpeaker Deck

  With the evolution of software delivery methods, feature flags became one of the ways to deliver features and get user feedback. Modern applications may have hundreds of feature flags describing customizations, preview features, and environment specifics. Feature flags are not just a single toggle anymore, their values are often determined at runtime depending on the instance, user context, and inputs from the control plane.

  In this session, we will talk about OpenFeature - a new collaboration by many feature flag vendors and end users. OpenFeature, a CNCF sandbox project, is an open standard for feature flag management, created to support a robust feature flag ecosystem using cloud native technologies and to make feature flags a commodity. OpenFeature provides a unified API and SDKs, and a developer-first, cloud-native implementation, with extensibility for open-source and commercial offerings.

  We will provide adoption examples from the open-source projects from the Java and Cloud Native ecosystems.
