This year marks the first time the Jenkins project is participating in Outreachy. Outreachy is a program similar to Google Summer of Code (GSoC) where interns work on open source projects for a paid stipend. The key difference is that Outreachy reaches out to underrepresented groups and those who face systemic bias or discrimination in the technology industry in their home country. Once I learned about this...

There are now three different Docker Hub repositories that are or have been used as the "official" Jenkins image. This article aims at providing a clarification about which one is the current official one (as of December 2018 :-)). The official one docker pull jenkins/jenkins i.e. https://hub.docker.com/r/jenkins/jenkins/ is the right repository to use. I also documented some time ago on my blog the recommended way to run Jenkins using...

This allows administrators to install today’s security fixes without having to upgrade to the new LTS line immediately. For an overview of what was fixed, see the...

The GSoC Mentor Summit is where mentors of all organizations participating in the GSoC program are invited each year to learn and network with mentors from other organization, and make GSoC a better program.

In a past blog post, Delivery Pipelines, with Jenkins 2, SonarQube, and Artifactory, we talked about pipelines which result in binaries for development versions, and in Delivery pipelines, with Jenkins 2: how to promote Java EE and Docker binaries toward production, we examined ways to consistently promote applications toward production. In this blog post, I continue on both by discussing more details on security related quality gates and bringing...

In my daily work I often have to create or modify Jenkinsfiles and more often than I would like, I make mistakes. It is a very tedious workflow when you make a change to your Jenkinsfile, create a commit, push the commit and wait for your Jenkins Server to tell you, that you have missed a bracket. The Command-line Pipeline Linter (https://jenkins.io/doc/book/pipeline/development/) does a great...
