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...

I would like to introduce Custom WAR Packager - a new tool for Jenkins administrators and developers. This tool allows packaging custom Jenkins distributions as WAR files, Docker images and Jenkinsfile Runner bundles. This tool allows packaging Jenkins, plugins, and configurations in a ready-to-fly distribution. Custom WAR packager is a part of the Ephemeral Jenkins master toolchain which we presented in our A Cloud Native Jenkins blogpost. This toolchain is already used...

More and more today, continuous delivery (CD) pipelines are making use of containers. In many implementations, the primary workflow/orchestration tool for CD pipelines is Jenkins. And the primary container orchestration tool is Docker. Together these two applications provide a powerful, yet simple to understand and use, model for leveraging containers in your CD pipeline. When creating a pipeline script in Jenkins, there are multiple ways to incorporate Docker...

This is a guest post by Liam Newman, Technical Evangelist at CloudBees. There are less than three weeks left until Jenkins World 2017. Like last year, I’ll be at the "Ask the Experts" booth to answer questions about all things Jenkins. In preparation, I’ve started a continuing series of quick tutorial videos that answer some of the most common questions I’ve seen asked in the community forums. These are by no means...

With the ongoing migration to Azure, I would like to share my thoughts regarding one of the biggest challenges we have faced thus far: orchestrating container infrastructure. Many of the Jenkins project’s applications are run as Docker containers, making Kubernetes a logical choice as far as running our containers, but it presents its own set of challenges. For example, what would the workflow from development to production look like? Before going deeper...

This is a guest post by Brian Dawson at CloudBees, where he works as a DevOps Evangelist responsible for developing and sharing continuous delivery and DevOps best practices. He also serves as the CloudBees Product Marketing Manager for Jenkins. Last fall CloudBees asked attendees at the Jenkins User Conference – US West (JUC), and other in the Jenkins community to take a survey. Almost 250 people did – and...

Over 2,000 members of the Docker community attended Docker Hack Day events around the world. One of the forty-two Docker Hacks has some familiar names attached... Nicolas De Loof and Yoann Dubreuil from Docker Rennes, who are also active in our community, waved the Jenkins flag in this event and produced Jenkins docker slaves plugin. This plugin lets you run builds inside containers, and in that...

Nicolas De Loof will host an office hour next Wednesday 11 AM PDT on integrating Kubernetes with Jenkins. Kubernetes is an open-source project by Google that provides a platform for managing Docker containers as a cluster. During this session, Nicolas will introduce Kubernetes, explain how it can benefit Jenkins and demonstrate the Kubernetes Plugin. Then he will discuss the design of the Kubernetes plugin and plans...

(This is a guest post from Michael Neale) Recently at the Docker Conference (DockerCon) the Docker Hub was announced. The hub (which includes their image building and storage service) also provides some "official" images (sometimes they call them repositories - they are really just sets of images). So after talking with all sorts of people we decided to create an official Jenkins image - which is hosted...
