Jenkins

Jenkins Kubernetes setup As a team, we introduced Jenkins Kubernetes for every user a few months ago. Our goal was to make it easy to get started with Jenkins — no need for your own agent. We prepared guides on how to use it, which tools are already included in the image used by the pod (maintained by us). A few nodes are always ready, and autoscaling is active for more. The pod YAML is configured and maintained by us in the Jenkins cloud configuration. For higher security, we wrapped the Jenkins pods in a Docker-in-Docker environment, which leaves the user with full root permissions within the...

Hello everyone! I am Mallikarjun G D, and I have been a GSoC 2026 contributor for the project Continue: AI-Powered Chatbot for Quick Access to Jenkins Resources. Over the past few months, I have learnt a lot, not just about AI and Jenkins, but also about contributing to a large open-source project. So for my final GSoC blog, I wanted to share how the whole journey actually went. Before GSoC My journey with Jenkins started pretty randomly. I was learning Jenkins, got curious about its open-source codebase, and while exploring the GitHub organization, I stumbled across the resources-ai-chatbot-plugin. I found out it had started as a GSoC...

The following scenario is a case study. A Jenkins build fails in an integration test. The console contains a NoSuchMethodError, so the immediate task seems straightforward: find the incompatible dependency. Then someone points out that the last three builds failed too. Another developer asks whether the dependency change was already present in a successful build. The error is useful, but it has not yet established the investigation boundary. That boundary matters. A log describes what happened during one execution. Investigating a regression also requires knowing what worked before it, which changes arrived afterward, and whether later failures represent the same problem. The...

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...

We are excited to announce the Contributor Summit Virtual Event happening on September 11, 2026. The Contributor Summit is an opportunity for Jenkins contributors, users, and enthusiasts to come together, share knowledge, and collaborate on the future of Jenkins. Mark your calendars and join us for a day of insightful sessions, networking, and community building. Event Details The summit will be entirely online. Join us for all the sessions or just a few. Jenkins Contributor Summit 2026: The virtual hackathon We will be hosting a virtual hackathon on September 11, 2026, from 08:30 to 19:30 CEST. The event will be conducted online, allowing participants from around the world...

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...

Hey everyone! This post marks the end of my Google Summer of Code 2026 project, Jenkins email notifications using Outlook SMTP with OAuth. It’s been a great few months working across the email-ext, oauth-credentials, and entra-oauth plugins with my mentors Alex Earl and Kris Stern. If you want the first half of the story, my midterm update has it. Table of Contents About the Project Recap: Where Things Stood at Midterm Progress After Midterm What Still Needs Fixing All the PRs What I’ve Learned Acknowledgements Follow Along About the Project email-ext only supported username/password-based SMTP authentication, which doesn’t work for Google Workspace or Microsoft Entra environments that require OAuth 2.0.
