This CloudBees presentation illustrates using Groovy rather than Java for the plugin itself: https://www. cloudbees. com/event/topic/groovy-way-write-jenkins-plugin this can be an more and more well known strategy as a result of energy and straightforwardness of Groovy. It additionally explains how one can exchange Jelly with Groovy—using an analogous language (Gradle is predicated on Groovy, so… it is all Groovy! ) in the course of the improvement procedure makes loads of feel. Jenkins and Docker Docker is an software that allows you to package deal an software besides all of its dependencies right into a unmarried unit (a Docker box) that may be model managed and deployed in a simple and standardized manner. The Docker domestic web page explains how Docker works and the way to put in and use it: https://www. docker. com/what-docker. Conceptually, Docker packing containers are just like light-weight digital machines, yet they've got a few primary architectural variations that cause them to extra light-weight and extra effective, as illustrated by means of the subsequent Docker and digital desktop comparability diagrams. the next determine exhibits a standard digital computer: the subsequent determine exhibits a Docker box: Docker bins will be released and controlled with each switch recorded. they're like hugely effective VMs controlled lower than a model regulate approach that gives services just like Git. also they are hugely configurable and supply versatile and scalable deployment strategies. as well as the auditing and simplicity of use, there's additionally a ensure that boxes can be (and behave) the exact same on any surroundings that's in a position to operating Docker. this may get rid of the various environmental discrepancies which are regularly linked to sleek software program improvement, removing the outdated good, it really works on my computer syndrome, and the delicate variances among (supposedly exact) environments that typically reason critical and hard-to-detect matters. Like Jenkins, Docker is intensely versatile, really robust, and hugely extendable. no longer unusually, they paintings super good jointly. there are numerous ways that you could mix and leverage the facility of Docker and Jenkins. those methods in general suggest utilizing both Docker in Jenkins or Jenkins in Docker. Docker in Jenkins utilizing the Docker plugin for Jenkins (https://wiki. jenkins-ci. org/display/JENKINS/Docker+Plugin), you could arrange Jenkins jobs that may practice a assured fresh construct each time in a clean and known-good Docker box. this is often performed by means of dynamically provisioning a brand new slave node for the task to run on (pulled from a version-controlled Docker Hub). The construct or assessments can then be run in this atmosphere, and the implications might be recorded and archived. the total atmosphere can then be deleted with the be sure that, when you ever desire to, combining that very Docker box with an identical model of the deployed code will recreate the exact same effects at any destiny date and on any atmosphere.
