We would like to announce the availability of official Windows agent images for Docker. These images allow provisioning Jenkins agents with Windows OS on Docker and Kubernetes. New images All official Docker images for agents now provide nanoserver-1809 and windowsservercore-1809 tags which include Windows images and, at the moment, Java 8 (these are like the latest tag). We also provide tags with explicit Java selection, e.g. jdk8-windowsservercore-1809 or...

We would like to announce the renaming of the official Docker images for Jenkins agents. It does not have any immediate impact on Jenkins users, but they are expected to gradually upgrade their instances. This article provides information about the new official names, upgrade procedure, and the support policy for the old images. We will also talk about what’s next for the Docker packaging in Jenkins. New image...

In addition to WAR files and Docker images, the Jenkins project provides native installers for each weekly and LTS release.

At end of the first GSoC phase, I announced the first alpha release of the CLI tool and library that will help centralize plugin management and make plugin tooling easier. Phase 2 has mainly been focused on improving upon the initial CLI and library written in Coding Phase 1. In particular, we’ve been focusing on getting the tool ready to incorporate into the Jenkins Docker Image to replace the install-plugins.sh bash...

"Everybody is re-inventing the wheel, partially implementing the "details" of plugin management (signed metadata, artifacts checksums, plugins detached from core,…​). It becomes obvious Jenkins should provide adequate tooling for plugin installation outside a live Jenkins instance." JENKINS-53767 My Google Summer of Code project tries to solve this problem by creating a library that will unify plugin management logic across the different implementations of Jenkins and providing a CLI tool that...

Step 1 This is the default look and feel for a Windows...
