Last week we hosted our first ever Online JAM with the debut topic of: Jenkins 2.0. Alyssa, our Events officer, and I pulled together a series of sessions focusing on some of the most notable aspects of Jenkins 2 with: A Jenkins 2.0 keynote from project founder Kohsuke Kawaguchi An overview of "Pipeline as Code" from Patrick Wolf A deep-dive into Pipeline and related plugins like Multibranch, etc from Jesse Glick and Kishore Bhatia An overview of...

Over the past 10 years, Jenkins has really grown to a de-facto standard tool that millions of people use to handle automation in software development and beyond. It is quite remarkable for a project that originally started as a hobby project under a different name. I’m very proud. Around this time last year, we’ve celebrated 10 years, 1000 plugins, and 100K installations. That was a good time to retrospect, and we...

Last week, the infrastructure team identified the potential compromise of a key infrastructure machine. This compromise could have taken advantage of, what could be categorized as, an attempt to target contributors with elevated access. Unfortunately, when facing the uncertainty of a potential compromise, the safest option is to treat it as if it were an actual incident, and react accordingly. The machine in question had access to binaries published...

Those of you who routinely apply all plugin updates may already have noticed that the version numbers of the plugins in the Pipeline suite have switched to a 2.x scheme. Besides aligning better with the upcoming Jenkins 2.0 core release, the plugins are now being released with independent lifecycles. “Pipeline 1.15” (the last in the 1.x line) included simultaneous releases of a dozen or so...

In this post I will show how you can make your own DSL extensions and distribute them as a plugin, using Pipeline Script. A quick refresher Pipeline has a well kept secret: the ability to add your own DSL elements. Pipeline is itself a DSL, but you can extend it. There are 2 main reasons I can think you may want to do this: You want to reduce boilerplate by...

This is a cross-post of an article authored by Viktor Farcic on the CloudBees blog. Viktor is also the author of The DevOps 2.0 Toolkit, which explores Jenkins, the Pipeline plugin, and the ecosystem around it in much more detail. Over the years, Jenkins has become the undisputed ruler among continuous integration (CI), delivery and deployment (CD) tools. It, in a way, defined the CI/CD processes we use today. As a result of...

This is a cross-post of an article authored by Pipeline plugin maintainer Jesse Glick on the CloudBees blog. For those of you not checking their Updates tab obsessively, Pipeline 1.14 [up to 2.1 now] was released a couple of weeks ago and I wanted to highlight the major feature in this release: JENKINS-32727, or replay. Some folks writing "Jenkinsfiles" in the field had grumbled that it was awkward to develop the script incrementally, especially...

This is a guest post by Alyssa Tong. Alyssa works for CloudBees, helping to organize Jenkins community events around the world.

This event will bring together Jenkins experts, continuous delivery thought leaders and the ecosystem offering complementary technologies for Jenkins. Join us September 13-15, 2016 in Santa Clara, California to learn and explore, network...
