With Jenkins being a server-based application, you need a web server, like Apache Tomcat, to make the application operable. By integrating a large number of testing and deployment technologies, Jenkins lets you deliver your software products continuously. It is capable of combining the various phases of the development life cycle, such as build, test, package, deploy, analysis, and many others. A pipeline is a set of steps the Jenkins server will execute to complete the CI/CD process’s necessary tasks.
But that meant testing one’s changes in isolation, without everyone else’s daily commits. There was no firm guarantee that the nightly build would survive the latest commit. Jenkins is a CI/CD tool, open-source, compatible with various plugins, and makes life easy when software delivery has to be https://www.globalcloudteam.com/ done on an agile basis. Continuous Integration is the most important part of DevOps that is used to integrate various DevOps stages. Jenkins is the most famous Continuous Integration tool, I know you are curious to know the reason behind the popularity of Jenkins, and if Jenkins is easy to learn.
Step 2: Creating a Pipeline
You can hover to any stage and have a look at the logs of that particular stage. As shown in the Console Output, the test scenario was executed successfully where the Chrome WebDriver was instantiated and required actions were performed on the webpage under test. As shown below, the configuration of tools (i.e. JDK and Maven) was successful. The TestNG test framework is used for performing Selenium test automation. For a quick recap on TestNG, you can refer to this guide for creating TestNG Project In Eclipse.
CI/CD servers, including Jenkins, allow your team to set up the tests that you need to run. CI is run on a shared server that increases visibility, so all the engineers on a project are aware of changes in the base code day in and day out. In addition, you can configure the server to alert developers when they submit failing code so that they can fix any errors they introduce. Automation, including CI/CD and test automation, is one of the key practices that allow DevOps teams to deliver “faster, better, cheaper” technology solutions.
How To Configure Jenkins?
In this section of What is Jenkins blog, we demonstrate the usage of the Declarative Jenkins pipeline for Maven project. The Jenkins Pipeline executes on a node block that is usually a part of the Scripted Pipeline syntax. Scripted Pipeline is a more traditional way of writing a Jenkins Pipeline as code. The Web UI of Jenkins is normally definition of Jenkins used for writing the Scripted Pipeline in a Jenkinsfile. Earlier in this ‘what is Jenkins’ blog section titled Master- Agent Architecture in Jenkins, we had a look at the architecture of Jenkins. Here, we will demonstrate the creation of Jenkins Agents (or Nodes) on Windows 10 to further understand how does Jenkins work.
These features make Jenkins a must-have tool for organizations seeking to implement DevOps practices and enhance their software delivery processes. Originally developed by Kohsuke for continuous integration (CI), today Jenkins orchestrates the entire software delivery pipeline – called continuous delivery. For some organizations automation extends even further, to continuous deployment. Continuous delivery (CD), coupled with a DevOps culture, dramatically accelerates the delivery of software.
What Is Jenkins?
A timeout step determines when Jenkins should exit an unsuccessfully retried step. For these reasons, many teams are transitioning away from Jenkins and adopting newer solutions that are more supportive of a containerized, microservices-oriented DevOps environment. You can use multiple Jenkins Agents to balance build load, improve performance, and create a secure environment independent of the Controller.
It also enables you to release your software continuously by interacting with various testing and deployment methods. This wikiHow teaches you how to install the Jenkins automation server on your computer. Jenkins is an open-source, Java-based automation server that allows you to automate your software development process with continuous integration. While writing and checking in code as a developer, you can use Jenkins to easily automate the non-human functionalities like build, test, deploy, package, and integrate.

Additionally, Jenkins integrates with several security-related plugins to further enhance its security capabilities. Teams that adopt Codefresh deploy more often, with greater confidence, and are able to resolve issues in production much more quickly. This is because we unlock the full potential of Argo to create a single cohesive software supply chain. For users of traditional CI/CD tooling, the fresh approach to software delivery is dramatically easier to adopt, more scalable, and much easier to manage with the unique hybrid model. The Delivery pipeline model also allows the creation of a single reusable pipeline that lets DevOps teams build once and use everywhere.
With its robust features, Jenkins enables seamless integration, continuous delivery, and efficient testing. Its extensive plugin ecosystem and strong community support make it an essential tool for achieving automation goals effectively. At 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.
Project (Formerly Job)
In the context of Jenkins, a pipeline refers to a collection of jobs (or events) connected in a specific order. It is a collection of plugins that allow the creation and integration of Continuous Delivery pipelines in Jenkins. Next, the contents of Jenkins are saved locally in a Jenkinsfile as plain text.
- Upon the successful completion of each step, the pipeline will continue to the next one.
- The Google Play Publisher plugin lets you send builds to an alpha channel in Google Play for release or further testing on actual devices.
- So when you incorporate Jenkins into your suite of development tools, you will find it easier to develop applications that leverage the microservices architecture.
- Courses may also cover other aspects of the deployment process, including working with serverless architecture, setting up Kubernetes, and building Python functions.
- The Pipeline also provides a set of tools that are useful for modeling simple as well as complex delivery pipelines ‘as code’ through ‘Pipeline Domain-Specific Language (DSL)’ syntax.
- Kawaguchi wrote at the time that nothing of significance would change for users.
Jenkins is a highly extensible product whose functionality can be extended
through the installation of plugins. If you want to extend the functionality of Jenkins by developing your own
Jenkins plugins, please refer to the Extend Jenkins
(developer documentation). Welcome to the Jenkins user documentation – for people wanting to use

It’s free software, and you can easily extend its functionality by writing your own Java plugins. Jenkins pipelines are a versatile and powerful way to define and automate software delivery processes. They allow for the creation of continuous integration and continuous delivery (CI/CD) pipelines, enabling teams to efficiently build, test, and deploy applications. The main purpose of Jenkins is to automate the continuous integration and delivery processes in software development. It allows for the seamless building, testing, and deployment of applications, ensuring faster and more efficient development cycles. Jenkins is the most widely adopted solution for continuous delivery, thanks to its extensibility and a vibrant, active community.
