In early February numerous free and open source developers from around the world traveled to Brussels, Belgium, for arguably the largest event of its kind: FOSDEM. Among the thousands of hackers in attendance were a dozen or so Jenkins contributors. We have attended the event in the past, but this year we had a blizzard of activity spanning four days around the FOSDEM weekend. Figure 1. City Hall, photo by Kohsuke...

I do not think it is an exaggeration to say: 2016 was the best year yet for the Jenkins project. Since the first commit in 2006, the project has reached a number of significant milestones in its ten years but we have never experienced the breadth of major milestones in such a short amount of time. From Jenkins 2 and Blue Ocean to the Google Summer of Code and Jenkins World, I wanted to take...

The Jenkins security team has been made aware of a new attack vector for a remote code execution vulnerability in the Jenkins CLI, according to this advisory by Daniel Beck: We have received a report of a possible unauthenticated remote code execution vulnerability in Jenkins (all versions). We strongly advise anyone running a Jenkins instance on a public network disable the CLI for now. As this uses the same attack vector as SECURITY-218, you can reuse the...

This is a guest post by Jenkins World speaker R Tyler Croy, infrastructure maintainer for the Jenkins project. I don’t think I have ever met a tools, infrastructure, or operations team that did not have a ton of work to do. The Jenkins project’s infrastructure "team" is no different; too much work, not enough time. In lieu of hiring more people, which isn’t always an option, I have found heavy automation...

This is a guest post by R. Tyler Croy, who is a long-time contributor to Jenkins and the primary contact for Jenkins project infrastructure. He is also a Jenkins Evangelist at CloudBees, Inc. I have been heavily using Jenkins Pipeline for just about every Jenkins-related project I have contributed to over the past year. Whether I am building and publishing Docker containers, testing infrastructure code or publishing this very web site, I have been...

At previous Jenkins User Conferences we have hosted "Contributor Summits" to gather developers and power-users in one room to discuss specific areas of Jenkins, such as Scalability, Pipeline, etc. As part of this year’s Jenkins World we’re hosting another Contributor Summit, to discuss: Blue Ocean, Pipeline and Storage Pluggability. Contributors to these three areas of the Jenkins ecosystem will be in attendance to present details of their design, requirements, and tentative roadmaps. After...

This is a guest post by R. Tyler Croy, who is a long-time contributor to Jenkins and the primary contact for Jenkins project infrastructure. He is also a Jenkins Evangelist at CloudBees, Inc. I find the topic of "scaling Jenkins" to be incredibly interesting because, more often than not, scaling Jenkins isn’t just about scaling a single instance but rather scaling an organization and its continuous delivery processes. In many cases...

At this year’s Jenkins World, our events officer Alyssa has been working to organize various activities in the "Open Source Hub" on the expo floor. Both days of the conference (Sept. 14th and 15th), during the break for lunch, there will be 15 minute demos by many of the experts helping to staff the Open Source Hub. Demo Schedule Wednesday, September 14th Time Session Details Presenter 12:15 - 12:30 Blue Ocean in Action Showcase of Blue Ocean and...

Our events officer Alyssa has been working for the past several weeks to organize the "Open Source Hub" at Jenkins World 2016. The Hub is a location on the expo floor where contributors to the Jenkins project can hang out, share demos and help Jenkins users via the "Ask the Experts" program. Thus far we have a great list of experts who have volunteered to help staff the booth, which...

This is a guest post by R. Tyler Croy, who is a long-time contributor to Jenkins and the primary contact for Jenkins project infrastructure. He is also a Jenkins Evangelist at CloudBees, Inc. When the Ruby on Rails framework debuted it changed the industry in two noteworthy ways: it created a trend of opinionated web application frameworks (Django, Play, Grails) and it also strongly encouraged thousands of developers to embrace test-driven development along...
