On December 15, the Toulouse JAM was co-hosted with the Toulouse JUG and Toulouse DevOps. Indeed it made sense since Jenkins is written in Java, makes use of Groovy code in many places (system groovy script, job dsl, workflow…​), and it also made sense to co-organize with the local DevOps community since Jenkins is also a great tool to enable Continuous Integration, Continuous Delivery and automation in general. There were 103 RSVPs, with 80 to 90 people in attendance. There were 3 talks planned for the evening: Job DSL Intro [fr], by Ghislain Mahieux Video recording Workflow plugin [fr], by Michaël Pailloncy (co-maintainer of the Build Trigger Badge plugin) Video recording Feedback on almost 10 years of CI and what’s upcoming [fr], demo with Jenkins build scaling with Docker Swarm, by Baptiste Mathus Video recording Photos can be found here

Thank you to Netflix for sponsoring the yummy burrito bar and offered up their brand new auditorium to host Jenkins Developers and Users Meetup group on Dec 16. We had 96 RSVPs which was impressive. Our speaker for the evening was Akshay Dayal, Software Engineer at Google. Akshay’s session was about Scaling Jenkins - how and why Google decided to scale their existing Jenkins cluster (OSS) to meet their security/availability and failover requirements and how heavy automation played an important role in this effort. The second talk was about how Google worked with Jenkins to read config data externally. Slides are listed below. The video will be posted on the meetup page) once it becomes available. Slides for the talks are linked below: Scaling Jenkins External Project Check out where Jenkins Area Meetups (JAMs) are located in the world.

Although December is a short month due to the holidays, there has been a good amount of local Jenkins activities that took place regardless of holiday obligations. Today and tomorrow I will be doing a series of posts to summarize December JAM World Tour. Special thanks to the JAM organizers and co-organizers who made it all happen in these cities: Lima, Peru St.Petersburg, Russia Toulouse, France Bay Area, CA On December 9 Lima JAM hosted their first Jenkins meetup in Lima, Peru. There were attendance from various roles of DevOps: Dev, QA, and Ops. There was also a good mixture of different levels of Jenkins users, some were new and just starting to use Jenkins while others had extensive Jenkins experience. The group has been invited by Docker and Ansible meetup organizers for a joint event in January to showcase technologies from Jenkins, Docker, and Ansible. Congrats to Lima JAM group. Slides from the meetup can be found here. Additional shared resources used in the Lima JAM can be found here. Check out where Jenkins Area Meetups (JAMs) are located in the world.

The first Jenkins meetup in Saint Petersburg, Russia took place on December 9th. The event has been organized with the help from Yandex and CloudBees. In total there were about 80 attendees at the meetup. In addition to meetup.com the event has been promoted by Yandex so we quickly reached capacity limit. There were 3 talks conducted, speakers from Yandex, ZeroTurnaround and CloudBees. We discussed the current open-source project state, ongoing activities in the community, Jenkins-powered CD case studies from ZeroTurnaround and Jenkins plugin development approaches.

A lot of people are using the Workflow plugin, but as with any scripting environment, users often have to start from scratch and learn the same lessons and shortcuts that other users have already learned. While there are blog posts from developers and users in various places, and some samples in the Workflow plugin documentation, more examples and tips and tricks are always, always useful. To help with that, we’ve created the workflow-examples repository on GitHub, as a place to store community-developed Workflow scripts that can help new users get started, show how to accomplish some non-trivial goals, and find tips and trick for taking your Workflow pipeline to the next level. The repository has four directories: docs/ - documentation, guides, and more. Including a Best Practices document. We’d love to see more contributions to that doc, as well as any new ones that would be helpful to Workflow users! workflow-examples/ - general Workflow examples, showing how to use a given plugin with Workflow, quirks of the Workflow DSL syntax, and more. global-library-examples/ - examples of how to write code for the Workflow global library. jenkinsfile-examples/ - Sample Jenkinsfiles or other Workflow scripts from SCM . During Hacksgiving some initial content was added, but not everything is covered yet, which is why I’m posting this - more is needed. We’d love to see your tips, examples, gotchas and more. If you’ve got Workflow scripts you’d like to contribute, please read the README and send a pull request. Thanks!

We released Jenkins updates today that include important security fixes: 1.641 and 1.625.3. For detailed information about the security content of these updates, see the security advisory. One of these fixes, SECURITY-95, results in possible problems in plugins such as Maven Plugin, Javadoc Plugin, and HTML Publisher Plugin, so make sure to read all about that in the documentation.
