What Is Jenkins? Key Concepts, Architecture & Pros Cons

Continuous integration is one of the most important terms used in DevOps when it comes to integrating different DevOps stages. Jenkins is the most popular and widespread tool that DevOps teams use to create software projects by developing and testing them continuously. It offers hire jenkins developers the most needed automation to accelerate the development process. With a plethora of continuous integration tools available out there, Jenkins is among the top-ranked ones. Jenkins is an open-source automation tool developed in Java primarily for continuous integration.

It is evident from the above-stated problems that not only the software delivery process became slow but the quality of software also went down. So to overcome such chaos there was a dire need for a system to exist where developers can continuously trigger a build and test for every change made in the source code. Jenkins is the most mature CI tool available so let us see how Continuous Integration with Jenkins overcame the above shortcomings.

It’s a free, open-source solution, and you can customize your Jenkins distribution to your needs. Furthermore, the backbone of this tool is the Jenkins community. This incredible community supports the project and plays a significant role in its success.

  • This allows the development teams to detect the problems early.
  • So to overcome such chaos there was a dire need for a system to exist where developers can continuously trigger a build and test for every change made in the source code.
  • CI will be paused and therefore requires some developer’s team attention.

  • Hence, alias maven and jdk pointing to the respective Maven and JDK versions are added under the tools directive.
  • For example, a command prompt code may be converted into a GUI button click using Jenkins.

Focuses on the distributed architecture of Jenkins and also explains how to create a build in Jenkins.

Jenkins Pipelines

In 2004, Kohsuke Kawaguchi was a Java developer at Sun Microsystems. Kawaguchi was tired of breaking builds in his development work and wanted to find a way to know, before committing code to the repository, whether the code was going to work. So Kawaguchi built an automation server in and for Java to make that possible, called Hudson. Hudson became popular at Sun, and spread to other companies as open source. Jenkins offers a simple way to set up a continuous integration and continuous delivery environment for almost any combination of languages and source code repositories. The leading open source automation server, Jenkins provides hundreds of plugins to support building, deploying and automating any project.

Jenkins X combines Jenkins with open source tools like Helm, Docker, Nexus, and KSync. It automatically installs, configures, and upgrades these tools to integrate them into your CI/CD process. Groovy expertise requirements—Jenkins https://globalcloudteam.com/ has programmatic pipelines implemented in Groovy, a language that is currently not in wide use and can make scripts difficult to work with. Jenkins optionally deploys the changes to the production server if the code has no issues.

Jenkins can deploy the build to an environment where user acceptance testing can be done before it goes into production. Yes, Jenkins is the top open-source automation server with hundreds of plugins to build, deploy, and automate any development project. Continuous development refers to the process of automating the development and packaging of source code and deploying it to testing and production environments. Continuous deployment is the process of automating the deployment of the source code to its desired destination. Although Jenkins started as a continuous integration tool, the current use covers the whole software delivery pipeline, including deployment.

In the Authorization strategy, select ‘Matrix-based security’. Search for httpPort in the file and change from 8080 to a preferred port of choice (e.g. 9090 in our case). As we mentioned in step-2 above, you need to have admin rights to perform this change.

Benefits and Drawbacks of Jenkins

Meanwhile, the Jenkins server checks the repository at regular intervals for changes. As is the case with most software, there are pros and cons to Jenkins. One of the advantages of Jenkins is that it can be extended using plugins. This makes Jenkins adaptable to changes in IT environments.
