Jenkins Tutorial

Jenkins is a powerful application that enables continuous integration and continuous delivery of projects on any platform. It is a free, open-source application of DevOps tools that can handle any type of build or continuous integration.  Jenkins can be integrated with a variety of testing and deployment technologies. 

In this Jenkins Tutorial blog, we will show you how to use the Jenkins DevOps tool to continuously build and test your software projects. 

Before we proceed with Jenkins Tutorial, the key takeaways from the previous blog are:

  • Jenkins is used to integrate all DevOps stages with the help of plugins.
  • Commonly used Jenkins plugins are Git, Amazon EC2, Maven 2 project, HTML publisher etc.
  • Jenkins has well over 1000 plugins and 147,000 active installations along with over 1 million users around the world.
  • With Continuous Integration every change made in the source code is built. It performs other functions as well, that depends on the tool used for Continuous Integration.
  • Nokia shifted from Nightly build to Continuous Integration.
  • Process before Continuous Integration had many flaws. As a result, not only the software delivery was slow but the quality of software was also not up to the mark. Developers also had a tough time in locating and fixing bugs.
  • Continuous Integration with Jenkins overcame these shortcomings by continuously triggering a build and test for every change made in the source code.

What is Jenkins?

Jenkins is an open-source automation server widely used for building, deploying, and automating any project for continuous integration and continuous delivery. It helps automate parts of the software development process, making it more efficient and reducing manual intervention. Jenkins is an amazing tool to build a CI/CD pipeline because of its flexibility, extensibility, and strong community support. Jenkins plays a crucial role in the DevOps toolchain by automating key processes and providing a flexible and extensible platform for developing, testing, and releasing software. 

History of Jenkins

The history of Jenkins dates back to the mid-2000s. The Jenkins project was started in 2004 by Kohsuke Kawaguchi, a software developer who began working on a project called Hudson while he worked for Sun Microsystems. Kohsuke created Hudson as a way to perform continuous integration. The goal was to create an extensible open-source continuous integration (CI) server that could automate the building and testing of software projects. Hudson gained popularity in the developer community due to its ease of use and extensibility. In 2011, a dispute arose within the Hudson community over the control and governance of the project. So, the Hudson community decided to fork the project. They created a new project named Jenkins, which retained the core features of Hudson but allowed for a more open and community-driven development model. And soon, Jenkins usage spread around the world. Today, Jenkins manages the entire software delivery pipeline.

Jenkins Tutorial: Why Jenkins?

Continuous integration is possible with Jenkins, a software program DevOps tool. 

A server where the central build will occur will have Jenkins installed on it. An extremely basic workflow for Jenkins is shown in the flowchart below.

Jenkins flowchart

It’s not uncommon to see Hudson mentioned in conjunction with the Jenkins DevOps tool. 

Developed by Sun Microsystems, which was later purchased by Oracle, Hudson is a very well-known open-source Java-based continuous integration tool. 

As a result of a fork in the Hudson source code following Oracle’s acquisition of Sun, Jenkins was developed.

What is Continuous Integration?

According to the development practice known as continuous integration, developers must periodically integrate new code into a shared repository. 

This idea was developed to solve the issue of discovering issues in the build lifecycle after they had already occurred. 

The developers must conduct frequent builds in order to use continuous integration. 

It is standard procedure to launch a build whenever a code commit takes place.

System Requirements

JDKJDK 1.5 or above
Memory2 GB RAM (recommended)
Disk Space No minimal standard exists. Note that enough disc space must be available for build storage because all builds will be stored on the Jenkins machines.
Operating System VersionJenkins can be installed on Windows, Ubuntu/Debian, Red Hat/Fedora/CentOS, Mac OS X, openSUSE, FReeBSD, OpenBSD, Gentoo.
Java ContainerThe WAR file can be run in any container that supports Servlet 2.4/JSP 2.0 or later.(An example is Tomcat 5).


Now is the correct time to understand Jenkins architecture.

Jenkins Tutorial: Jenkins Architecture

Let us revise the standalone Jenkins architecture that I have explained to you in the previous blog, below diagram depicts the same.

Jenkins Standalone Architecture - What is Jenkins - Edureka

This single Jenkins server was not enough to meet certain requirements like:

  • Sometimes you might need several different environments to test your builds. This cannot be done by a single Jenkins server.
  • If larger and heavier projects get built on a regular basis then a single Jenkins server cannot simply handle the entire load.

To address the above stated needs, Jenkins distributed architecture was introduced.

Jenkins Distributed Architecture

Jenkins uses a Master-Slave architecture to manage distributed builds. In this architecture, Master and Slave communicate through TCP/IP protocol.

Jenkins Master

Your main Jenkins server is the Master. The Master’s job is to handle:

  • Scheduling build jobs.
  • Dispatching builds to the slaves for the actual execution.
  • Monitor the slaves (possibly taking them online and offline as required).
  • Recording and presenting the build results.
  • A Master instance of Jenkins can also execute build jobs directly.

Jenkins Slave

A Slave is a Java executable that runs on a remote machine. The following are the characteristics of Jenkins Slaves:

  • It hears requests from the Jenkins Master instance.
  • Slaves can run on a variety of operating systems.
  • The job of a Slave is to do as they are told to, which involves executing build jobs dispatched by the Master.
  • You can configure a project to always run on a particular Slave machine or a particular type of Slave machine, or simply let Jenkins pick the next available Slave.

The diagram below is self-explanatory. It consists of a Jenkins Master which is managing three Jenkins Slave.

Jenkins Distributed Architecture - Jenkins Tutorial - Edureka

Now let us look at an example in which Jenkins is used for testing in different environments like: Ubuntu, MAC, Windows etc.

The diagram below represents the same:

Distributed Testing - Jenkins Tutorial - Edureka

The following functions are performed in the above image:

  • Jenkins checks the Git repository at periodic intervals for any changes made in the source code.
  • Each builds requires a different testing environment which is not possible for a single Jenkins server. In order to perform testing in different environments Jenkins uses various Slaves as shown in the diagram.
  • Jenkins Master requests these Slaves to perform testing and to generate test reports.

Jenkins DevOps Tool – Configuration

You may have noticed a few instances in the earlier exercises where we had to configure Jenkins options. The different configuration options in Jenkins are displayed in the following.

By selecting “Manage Jenkins” from the left-hand menu, one can access Jenkins’ various configuration tools.

manage jenkins The following screen will then appear for you:

manage jenkins window

Then select Configure System. Some of the settings for Jenkins configuration that can be used are covered below.

configure system page

A crucial component of configuration is the configure system page. Generic Jenkins settings, global environment variables, and the majority of installed plugins are configured on this page. This screen represents several sections, each of which corresponds to a different configuration area.

Jenkins DevOps Tool – Home Directory

Jenkins needs a certain amount of disc space to run builds and store archives. This location can be verified from Jenkins’ configuration screen. This location will initially be saved in your user profile location and is set by default to /.jenkins. In a suitable setting, you should change this location to a suitable place to keep all pertinent builds and archives. There are several ways one can accomplish this.

Before launching the servlet container, set the “JENKINS HOME” environment variable to the new home directory.

  • The servlet container’s “JENKINS HOME” system property should be set.
  • Set the new directory as the “JENKINS HOME” environment variable for JNDI.
  • The first method of setting the “JENKINS HOME” environment variable will be used in the example that follows.

First, make a new Jenkins folder in E: Apps. Copy everything from the current /.Jenkins directory to this new directory.

The base directory location where Java is installed on your computer should be the value for the JENKINS HOME environment variable. For instance,

WindowsSet Environmental variable JENKINS_HOME to you’re the location you desire. As an example you can set it to E:AppsJenkins
Linuxexport JENKINS_HOME =/usr/local/Jenkins or the location you desire.

Click Manage Jenkins in the left-hand menu of the Jenkins dashboard. Then, from the right side, select “Configure System.”

You can now find the newly configured directory in the Home directory.

manage jenkins configure systems


This is the maximum number of jobs that can be executed simultaneously on the Jenkins machine. Depending on the circumstances, this can be altered. For better performance, it is sometimes advised to keep this number constant with the number of CPUs installed on the machines.

Environmental Factors:

Using this, you can add unique environment variables that apply to all jobs. These are key-value pairs that can be used wherever needed in Builds.

Jenkins URL:

The Jenkins URL defaults to pointing to localhost. Set this to the domain name if you have one set up for your computer; otherwise, localhost will be replaced with the IP address of the device. This will help in setting up slaves and sending out links using the email as you can directly access the Jenkins URL using the environment variable JENKINS URL which can be accessed as ${JENKINS URL}.

Email notification:  

You can set the SMTP settings for email sending in the Email Notification section. Jenkins needs to connect to the SMTP mail server and send emails to the recipient list, so this is necessary.

Jenkins DevOps Tool – Management

To manage Jenkins, select “Manage Jenkins” from the menu on the left.

By selecting “Manage Jenkins” from the left-hand menu, one can access Jenkins’ various configuration options.

jenkins devopps tool - management

You will then see the following screen:

manage jenkin windows for management

A few management options include the following:

Configure System:

Here, one can control the paths to the various build-related tools, including JDKs, Ant and Maven versions, security settings, email servers, and other system-level configuration information. the installation of plugins. After the plugins are installed, Jenkins will dynamically add the necessary configuration fields.

Reload Configuration from Disk:

All of Jenkins’ system and build job configuration information is kept in XML files that are kept in the Jenkins home directory. Additionally, the complete build history is kept here. You must add or remove the relevant build job directories from Jenkins’s builds directory if you are moving build jobs from one Jenkins instance to another or archiving old builds. You can reload the Jenkins system and build job configurations without taking Jenkins offline by using the “Reload Configuration from Disk” option.

Manage Plugin:

One can install a wide range of third-party plugins here, ranging from metrics reporting for code quality and code coverage to different Source code management tools like Git, Mercurial, or ClearCase. The Manage Plugins screen allows for the installation, updating, and removal of plugins.

manage plugins

System Information

All of the current Java system properties and system environment variables are listed on this screen. Here, one can see the exact Java Jenkins version, user, and other information that is running.

The name-value data that is presented in this section is shown in part in the screenshot that follows.

System Log:

Jenkins log files can be conveniently viewed in real-time on the System Log screen. Again, troubleshooting is the main purpose of this screen.


log recorders


jenkin logsLoad Statistics:

The length of the build queue and the number of concurrent builds are shown graphically on this page to give you an idea of how busy the Jenkins instance is and how long your builds will need to wait before being executed. These statistics can help determine whether additional build nodes or capacity is needed in terms of infrastructure..

load statistics Script Console:

You can execute Groovy scripts on the server using this screen. Since it necessitates a thorough understanding of the internal DevOps Jenkins architecture, it is helpful for advanced troubleshooting.  

Script consoleManage nodes:

DevOps Jenkins can manage distributed and parallel builds. You can specify how many builds you want on this screen. Jenkins runs concurrently and configures build nodes if you are using distributed builds. Jenkins can use a build node as an additional computer to carry out its builds.

manage nodes


Prepare for Shutdown:

The best time to avoid shutting down Jenkins or the server it is running on is when a build is in progress. The Prepare for Shutdown link, which stops any new builds from starting, can be used to properly terminate Jenkins. One will eventually be able to shut down Jenkins cleanly once all of the ongoing builds have been completed.

Step 8: If you go back to Jenkins home, you’ll see an overview of all projects and their information, including status.

Build Status - Jenkins Tutorial - Edureka

Status of the build is indicated in two ways, by a weather icon and by a colored ball. The weather icon is particularly helpful as it shows you a record of multiple builds in one image.

As you can see in the above image, the sun represents that all of my builds were successful. The color of the ball gives us the status of that particular build, in the above image the color of the ball is blue which means that this particular build was successful.

In this Jenkins Tutorial, I have just given an introductory example. In my next blog, I will show you how to pull and build code from the GitHub repository using Jenkins.

Jenkins DevOps Tool – Notification

Due to their accessibility and ease of use, emails have become a vital part of every organization.

There are many plugins on the market that enable you to customize every aspect of email notifications, including the one we’ll see in Jenkins right now.

Jenkins email notification is a Java-based plugin tool that automatically notifies users whenever new emails are received. The CI (Continuous Integration) code will benefit from it.

Step 1: Select Manage Jenkins -> Manage Plugins from the menu.

Jenkins - notification step 1


Step 2: Select Manage Jenkins -> Configure System to set up an SMTP server.

Step 5: press the Save button.Then click Build Now.

Following a successful build, the aforementioned procedures will guarantee that all necessary files are deployed to the container.

Jenkins – Server Maintenance

The following are some of the fundamental tasks you’ll perform, some of which are best practices for maintaining Jenkins servers.

Optional URLs: 

The relevant actions will be performed on the Jenkins instance when the commands listed below are appended to the URL of the Jenkins instance.

http://localhost:8080/jenkins/exit − shutdown jenkins

http://localhost:8080/jenkins/restart − restart jenkins

http://localhost:8080/jenkins/reload − to reload the configuration

Jenkins DevOps Tool – Home Backup

Jenkins stores all the data for the jobs, builds, etc. in a single location on your drive called Jenkins Home Directory.

By selecting Manage Jenkins -> Configure System, you can view the home directory’s location.

Jenkins home backup



Jenkins devops tools- home backups


Jenkins should be installed on the partition with the most available disc space. Always make sure Jenkins is configured on a drive with enough hard disc space because Jenkins will be taking source code for the various jobs defined and performing continuous builds. All builds on the Jenkins instance will start failing if your hard drive fills up.

Writing cron jobs or maintenance tasks that can perform cleanup procedures is another best practice for preventing the disc where Jenkins is installed from filling up.

Jenkins DevOps Tool – Continuous Deployment

Continuous delivery and deployment are well supported by Jenkins. The process of developing software and then deploying it will look like what is shown below.

contineous deployement

The main goal of continuous deployment is to fully automate the process described above. Jenkins offers a variety of plugins for each of these “Deploy to container” plugins, which was seen in earlier sections, is one of them.

Jenkins offers several plugins that are used to display the continuous deployment process graphically.

Let’s first create a different project in Jenkins to see how it functions and to simulate the QA stage to understand that:

Step 1: Click New Item on the Jenkins Dashboard.

  4. Extensive Plugin Ecosystem: Jenkins has a vast ecosystem of plugins that enable integration with a wide range of tools and technologies. This extensibility makes Jenkins adaptable to different development environments and workflows.
  5. Support for Multiple Platforms: Jenkins is platform-agnostic and supports building and deploying applications on various operating systems, making it versatile for different development environments.

Disadvantages of Using Jenkins

  1. Learning Curve: Jenkins has a steep learning curve, especially for beginners. Configuring complex build pipelines and mastering the tool’s features may require time and training.
  2. Maintenance Overhead: Managing and maintaining Jenkins instances, updating plugins, and ensuring compatibility with other tools can be time-consuming. Regular maintenance is necessary to keep Jenkins secure and up to date.
  3. Resource Intensive: Jenkins can be resource-intensive, especially for large projects with numerous builds and frequent updates. Users need to plan for adequate server resources, and scaling may be required as the development workload increases.
  4. Security Concerns: As an open-source tool, security concerns are crucial. Users must follow best practices for securing Jenkins instances, including proper authentication, authorization, and staying up-to-date with security patches.
  5. Limited Support for Containerized Environments: While Jenkins supports containerization, more modern tools like Jenkins X are specifically designed for cloud-native and containerized environments. Traditional Jenkins may require additional configurations for seamless integration in such setups.
