In this post I wanted to show how you can run Jenkins behind a firewall (which could be a corporate firewall, a NAT’ed network like you have at home) but still receive webhooks in real time from GitHub.com. You can generalise this to other services too - such as BitBucket or DockerHub, or anything really that emits webhooks, but the instructions will be for...

Google Summer of Code is as program where students are paid a stipend by Google to work on a free open source project like Jenkins, at full-time for four months (May to August).

The end of a year is a great time to step back from the daily grind to look at the big picture. Across the industry, the relentless march toward more automation still continues on. We are writing software faster than ever, but the demand for software seems to be going up even more, and I feel more and more businesses and executives are keenly aware...

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 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...

We just released security updates to Jenkins, versions 2.154 and LTS 2.150.1, that fix multiple security vulnerabilities. Since 2.150.1 is the first release in the new LTS line, we also released 2.138.4, a security update for the previous LTS line. 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...
