What is Jenkins? Why Use Continuous Integration CI Tool?

I am pretty sure you all have used Nokia phones at some point in your life. In a software product development project at Nokia, there was a process called Nightly builds. Nightly builds can be thought of as a predecessor to Continuous Integration. It means that every night an automated system pulls the code added to the shared repository throughout the day and builds that code. The idea is quite similar to Continuous Integration, but since the code that was built at night was quite large, locating and fixing of bugs was a real pain.

In the context of Jenkins, a pipeline refers to a collection of jobs connected in a specific order. It is a collection of plugins that allow the creation and integration of Continuous Delivery pipelines in Jenkins. If all of the tests developed for a feature or release branch are green, Jenkins or another CI system may automatically publish code to staging or production.

Extending Jenkins with Plugins

Hudson became popular at Sun, and spread to other companies as open source. Travis CI branch build flow and pull request build flow with GitHubDirect connectivity with GitHub. Travis CI works seamlessly with popular version control systems, GitHub in particular.

Most serious software projects include an additional code base that is not explicitly responsible for the business product and features. This secondary code base is a test suite and acts as a set of assertions that assures the primary code base is working correctly without bugs. During development, these tests are run by developers to validate that new code has not caused what is jenkins any regression on existing features. These test cases can also be run by extraneous tools to automate this validation process. CI service products will automatically run the test cases for a project on user-specified events. Generally, when a developer pushes code using the version control system an event will trigger the full test suite to run automatically.

Enterprise services

One may parameterize Jenkins tasks to allow for customization or user input. Adding stages to a pipeline, upgrading the server with new features, and tracking plugin updates require an administrator to restart and manage the server manually. The feedback system helps the dev team quickly address the issues instead of debugging numerous commits.

It offers the most needed automation to accelerate the development process. Jenkins is an open source continuous integration/continuous delivery and deployment (CI/CD) automation software DevOps tool written in the Java programming language. It is used to implement CI/CD workflows, called pipelines. 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.


This functionality used to be a part of the core, but as of Jenkins 1.431, it was split off into separate plugins. On February 1, 2011, Oracle said that they intended to continue development of Hudson, and considered Jenkins a fork rather than a rename. Jenkins and Hudson therefore continued as two independent projects, each claiming the other was the fork.

While you can use the web UI to create scripts, the current best practice is to create a pipeline script, named Jenkinsfile, and check it into your repository. The screenshot below shows the configuration web form for a multibranch pipeline. It is a server-based application and requires a web server like Apache Tomcat.

CircleCI: an easy and useful CI tool for early-stage projects

The Jenkins server can access the Controller environment, which distributes the workload across different Jenkins Agents. DevOps is an ever-evolving ecosystem in the development industry, and the CI/CD tools in this domain are highly critical. CI/CD practices effectively handle the misalignment between developers and the operational team.

  • Although Jenkins requires scripting some automation steps, the program provides a fast and robust way to systematize the software development lifecycle.
  • The tools that automate code changes in software projects.
  • In the world of DevOps, professionals frequently work with pipelines.
  • It automatically installs, configures, and upgrades these tools to integrate them into your CI/CD process.
  • The need for Jenkins becomes especially acute when deploying to a microservices architecture.

In this blog, we will learn to create CI CD Pipeline using Jenkins. In general, CI tools increase engineering teams’ capacity to build high-quality software by yielding developers code views, integration tests, and other useful tooling. Having a CI process is not only beneficial for software developers, but for their managers as well. Both parties can gather valuable feedback and gain insights much faster. As you push code more often, you have more data available which you can analyze to check if the product is heading into the right direction. CI/CD tools can be hosted either on your server (on-premise) or on the side of a cloud provider.

Execute Jenkins as a Java binary

Focuses on the distributed architecture of Jenkins and also explains how to create a build in Jenkins. If the build fails, then the concerned team will be notified. It is built with Java and hence, it is portable to all the major platforms. IDGOnce you have picked your initial set of plugins, click the Install button and Jenkins will add them. Once installed, Jenkins allows you to either accept the default plugin list or choose your own plugins.
