![]() Jenkins facilitates continuous integration and continuous delivery in software projects by automating parts related to build, test, and deployment. This makes it easy for developers to continuously work on the betterment of the product by integrating changes to the project. Jenkins automates the software builds in a continuous manner and lets the developers know about the errors at an early stage. A strong Jenkins community is one of the prime reasons for its popularity. Execute test scripts (using Windows terminal, Linux shell, etc.Īutomation testing using test frameworks such as Nose2, PyTest, Robot, Selenium, and more.Software build using build systems such as Gradle, Maven, and more.Some of the possible steps that can be performed using Jenkins are: Jenkins is not only extensible but also has a thriving plugin ecosystem.Achieve test results and perform post actions such as printing test reports, and more.Execute test scenarios against different input combinations for obtaining improved test coverage.Continuous Integration (CI) where the artifacts are automatically created and tested.This aids in identification of issues in the product at an early stage of development.Īt the time of what is Jenkins blog, it had close to 1500+ plugins contributed by the community. Plugins help in customizing the experience with Jenkins, along with providing support for accelerating activities related to building, deploying, and automating a project. In this section of What is Jenkins blog, We will loo at the history of Jenkins. Jenkins has an early mover advantage since it has been in development since 2011. Kohsuke Kawaguchi created Jenkins (then called ‘Hudson’) while working at Sun Microsystems. Hudson was created in the summer of 2004 and the first release was in February 2005.Īfter the acquisition of Sun Microsystems by Oracle, a proposal was approved by the Hudson community for creating the Jenkins project. In February 2011, Oracle intended that the development of Hudson should continue hence, Hudson was forked instead of renaming it to Jenkins. Though Hudson and Jenkins were being developed independently, Jenkins acquired significantly more projects & contributors than Hudson. Consequently, Hudson is no longer maintained by the community. Like other open-source projects, Jenkins also produces two release lines – LTS (Long-Term Support) and Weekly (regular) releases. Jenkins is very good with releases, as stable releases happen every four weeks.Īt the time of this ‘, what is Jenkins’ article, the latest version of Jenkins LTS was 2.235.2, and Jenkins Weekly was 2.249. Jenkins is more functionality-driven rather than UI-driven hence, there is a learning curve involved in getting to know what is Jenkins. Here are the powerful developer-centric features offered by Jenkins: 1. Jenkins is a self-contained Java program that is agnostic of the platform on which it is installed. ![]() It is available for almost all the popular operating systems such as Windows, different flavors of Unix, and Mac OS. It is available as a normal installer, as well as a. Once installed, it is easy to configure using its web interface. Open-SourceĪs it is open-source, it is free for use. There is a strong involvement of the community which makes it a powerful CI/CD tool. You can take support from the Jenkins community, whether it is for extensibility, support, documentation, or any other feature related to Jenkins. The backbone of Jenkins is the community and the community members have been instrumental in the development (and testing) of close to 1500+ plugins available in the Update Center. Jenkins is designed in such a manner that makes it relatively easy to distribute work across multiple machines and platforms for the accelerated build, testing, and deployment. This Jenkins Tutorial for beginners and professionals will help you learn how to use Jenkins, one of the most popular CI/CD tools used in DevOps. ![]() In this section of the What is Jenkins blog, we look at the internal functioning of Jenkins i.e. what happens once the developer commits changes to the repository and how CI/CD is realized in Jenkins. We also look at the Master-Agent architecture in Jenkins. Developers do the necessary modifications in the source code and commit the changes to the repository.These are the series of steps that outlines the interaction between different elements in Jenkins: Architecture Of Jenkinsīefore we dive into how does Jenkins works, we must understand the architecture of Jenkins.
