Hi everyone 👋, I’m Daniele, the Google Summer of Code 2026 contributor who worked this summer on creating the AI Chatbot to Guide User Workflow plugin. The extended period of my project is coming to an end, and I want to share a bit about this brand-new plugin and my journey through GSoC. Index About the Project Second part of GSoC My contributions The plugin’s future Acknowledgements More about me About the Project The plugin integrates an agent-powered chatbot directly into the Jenkins interface. This tool is invaluable for both beginners who need guidance navigating the software and experts who want to quickly troubleshoot a failed build. The agent can perform a...

Your Jenkins setup represents a decade of institutional knowledge: countless custom pipelines, shared libraries, and specialized build agents. Yet when platform engineering enters the conversation, most IDP demos ignore this investment entirely. This article is for platform engineers and DevOps leads who run Jenkins at scale and are evaluating an internal developer platform. It lays out a different path: add one stage to your pipeline, and keep everything else exactly where it is – along with a clear model of the CI/platform boundary, a Jenkinsfile stage you can copy directly, and an honest account of what the trade costs. The most common misconception about...

Welcome back to the Plugin of the Month series, where we highlight useful and impactful tools from the Jenkins ecosystem. This September, we’re featuring a plugin that rethinks where your build artifacts actually live: the ORAS Artifact Manager Plugin. What is the ORAS Artifact Manager Plugin? By default, Jenkins stores archived artifacts and stashes on the controller’s local disk (or on whatever storage backend an artifact manager plugin provides). The ORAS Artifact Manager Plugin takes a different approach: it stores them in any OCI-compliant registry, using ORAS (OCI Registry As Storage). OCI registries were originally built to distribute container images, but the OCI ecosystem has...

Introduction Hi, my name is Mark. I am a Jenkins administrator, and I want to share some of my daily experiences using and maintaining Jenkins. I hope you enjoy it. Environment and setup We have two Jenkins servers, production and quality. Both run on a commercially supported Linux distribution, normally on the latest LTS version, with around 200 plugins installed. Production runs more than 6,000 builds every day and supports more than 1,000 users and 200 agents running Windows and Linux. On this note, most of the agents are maintained by the departments themselves. We offer guidance and also (limited) support. In addition to the Jenkins servers, we provide every...

Hello everyone, This blog showcases the work done on the Plugin Modernizer Stats Visualization project during Google Summer of Code 2026. For a detailed description of the project, please refer to the project page. Table of Contents About the Project Phase 1 Phase 2 Challenges and Learnings Next Steps Acknowledgements Useful Links About the Project The Plugin Modernizer Tool automates the modernization of Jenkins plugins using OpenRewrite recipes, creating pull requests with the results. As part of GSoC 2025, a metadata repository was established that stores raw modernization metadata in JSON/CSV format. My GSoC 2026 project, Plugin Modernizer Stats Visualization, builds a static visualization site that consumes this metadata, consolidates it into a...

Jenkins core stopped supporting Windows Server 2019 container images in Jenkins 2.569 and Jenkins 2.568.1. It is now time to drop Windows Server 2019 container images for the inbound agent container images and the SSH agent container images. Effective August 21, 2026, the Jenkins project will no longer deliver container images based on Windows Server 2019. We will continue to deliver container images based on newer versions of Windows Server, like Windows Server 2022 and Windows Server 2025. For users running Windows Server 2019 for their agents, the alternatives are: Upgrade to Windows Server 2022 or Windows Server 2025 Build their own agent image for Windows...

Welcome back to the Plugin of the Month series, where we highlight useful and impactful tools from the Jenkins ecosystem. August is here, bringing high temperatures and long, bright days. While we can’t turn down the sun outside, we can certainly give your eyes a break inside. When you spend hours looking at build logs, pipeline statuses, and administrative panels, a bright white screen can quickly turn into a source of glare and heat. This August, we are beating the summer heat with a cool, comfortable upgrade: the Dark Theme Plugin. What is the Dark Theme Plugin? The Dark Theme Plugin provides a sleek, modern dark...
