Over the years, Jenkins has become the unquestioned ruler among continuous integration (CI), delivery and deployment (CD) tools.
In today’s DevOps world, continuous delivery and deployment are critical to delivering high-quality software product faster than ever before. Jenkins is an open-source continuous integration server written in Java.
Jenkins offers a simple way to set up a continuous integration or continuous delivery environment for almost any combination of languages and source code repositories using pipelines.Jenkins also automate other routine development tasks. While Jenkins doesn’t eliminate the need to create scripts for individual steps, it does give you a faster and more robust way to integrate your entire chain of build, test, and deployment tools than you can easily build yourself.
Why Take This Course?
The goal of this course is to provide you with a working knowledge of Jenkins Continuous Integration(CI) tool. We’ll start with the basics, starting from installing Jenkins on different Operating Systems like Window, Mac and Linux.
This course has been designed and built by experts who will help break down Continuous Integration into small and easy to understand segments. We have created this tutorial as a guide to help newbies not only learn what is Jenkins CI, but also actually understand how to integrate Jenkins CI in their codes. We assume that you have no prior knowledge of Jenkins and Continuous Integration, but we do assume that you have an idea of how Ubuntu works, as well as basic virtualization concepts.
This Jenkins course uses a hands-on approach and is loaded with examples at every stage to help students actually understand and learn what is going on, rather than simply follow through with the videos and end up lost and confused later on. We also use an example project that the student will build along with the instructor.
The Jenkins course will cover important topics regarding CI and Jenkins such as what is Jenkins and continuous integration, a brief introduction to the Jenkins system, how to install Jenkins and integrate the CI, basic configuration of your Jenkins, and will also build a real-world example by creating and testing a Java application using Maven through Jenkins.
At the end of this Jenkins course, you will have learned exactly what is Jenkins CI, how it can help you and also how you can save yourself from hours of miserable code checking and debugging.
This course provides a robust foundation for implementing continuous inspection and integration at your company or studio. In order to keep the course short and to-the-point, several decisions were made in order to provide a complete path to continuous integration.
The Jenkins pipeline created in this course consists of the following:
Installing Jenkins CI server and configure it on Windows
Git and its source control system
Java as the main programming language of build projects
Maven as the build tool
This set of tools provides a comprehensive, end-to-end implementation continuous integration pipeline. Jenkins can be installed on many operating systems and supports a myriad of tools and technologies — which means, this Jenkins course provides tremendous value to those comfortable or interested in other operating systems and/or technologies.

What is Jenkins ?
Jenkins is the leading open-source automation server .
Jenkins is by far the most widely used tool for managing continuous integration builds and delivery pipelines. In case of building and testing software continuously Jenkins helps developers remarkably . Jenkins also increases the scale of automation that’s why in DevOps circles Jenkins is quickly gaining popularity.
Jenkins has around 1,400 plugins to support the automation of all kinds of development tasks. Those 1,400 plugins span five areas: platforms, UI, administration, source code management, and, most frequently, build management.
One of the key advantages of Jenkins is that it requires little maintenance and has built-in GUI tool for easy updates. Jenkins also provides customized solution as there are over 400 plugins to support building and testing virtually any project. Basically, Jenkins integrates development life-cycle processes of all kinds, including build, document, test, package, stage, deploy, static analysis and much more.
With Jenkins you can configure alerts in several ways, for example, you can receive email notification, pop-ups, etc. and actually automate it. By implementing the right configuration for you, you get almost immediate feedback. You will always know if the build broke. You will get to know what the reason for job fail was and you can also get to know how you can revert it back.
As a result of its leadership, many other products have tried to overthrow Jenkins from its position but failed. At the same time, new products emerged with a service approach. Some of them are Travis, CircleCI and Shippable. Be that as it may, none managed to get even close to Jenkins’ adoption. Today, depending on the source we use, Jenkins holds between 50-70% of the whole CI/CD tools market. The reason behind such a high percentage is the dedication Jenkins shows to open source principles set from the very beginning by Kohsuke Kawaguchi. Those same principles were the reason he forked Jenkins from Hudson. The community behind the project, as well as commercial entities behind enterprise versions, are continuously improving the way it works and adding new features and capabilities. They are redefining not only the way Jenkins behaves but also the CI/CD practices in a much broader sense.
Why we should use Jenkins ?
Jenkins is open source and it is user-friendly, easy to install and does not require additional installations or components.
Jenkins is free of cost.
Jenkins is sasily Configurable. Jenkins can be easily modified and extended. It deploys code instantly, generates test reports. Jenkins can be configured according to the requirements for continuous integrations and continuous delivery.
Jenkins is Platform Independent. Jenkins is available for all platforms and different operating systems, whether OS X, Windows or Linux.
Jenkins has Rich Plugin ecosystem. The extensive pool of plugins makes Jenkins flexible and allows building, deploying and automating across various platforms.
Jenkins has Easy support. Because it is open source and widely used, there is no shortage of support from large online communities of agile teams.
Jenkins Developers write the tests to detect the errors of their code as soon as possible. So the developers don’t waste time on large-scale error-ridden integrations.
In Jenkins issues are detected and resolved almost right away which keeps the software in a state where it can be released at any time safely.
In Jenkins most of the integration work is automated. Hence fewer integration issues. This saves both time and money over the lifespan of a project.
Jenkins and its integrated ecosystem provide the coordinating software infrastructure for agile development.
How Jenkins works ?
Jenkins is available as a Java 8 WAR archive and installer packages for the major operating systems, as a Homebrew package, as a Docker image, and as source code. The source code is mostly Java, with a few Groovy, Ruby, and Antlr files.
You can run the Jenkins WAR standalone or as a servlet in a Java application server such as Tomcat. In either case, it produces a web user interface and accepts calls to its REST API.
When you run Jenkins for the first time, it creates an administrative user with a long random password, which you can paste into its initial webpage to unlock the installation
Jenkins is a Continuous Integration server.
Basically Continuous Integration is the practice of running your tests on a non-developer machine automatically everytime someone pushes new code into the source repository.
Jenkins has the tremendous advantage of always knowing if all tests work and getting fast feedback. The fast feedback is important so you always know right after you broke the build what you did that failed and how to revert it.
If you only run your tests occasionally the problem is that a lot of code changes may have happened since the last time and it is rather hard to figure out which change introduced the problem. When it is run automatically on every push then it is always pretty obvious what and who introduced the problem.
Built on top of Continuous Integration are Continuous Deployment/Delivery where after a successful test run your instantly and automatically release the latest version of your codebase. Makes deployment a non-issue and helps you speed up your development.
