Jenkins as a deployment pipeline Technology Radar

The Android emulator plugin allows you to build and test on as many emulated devices as you care to define. The Google Play Publisher plugin lets you send builds to an alpha channel in Google Play for release or further testing on actual devices. The declarative pipeline can express most of what you need to define pipelines, and is much easier to learn than the scripted pipeline syntax, which is a Groovy-based DSL. The scripted pipeline is in fact a full-blown programming environment. 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 web page to unlock the installation.

  • The solution’s source code is predominantly Java, with some Groovy, Ruby, and Antlr files available.
  • Some steps can be used alongside other steps to make it easier to address issues such as retrying steps or timing out.
  • It sounds like a perfect way to develop software, but this process has many problems.
  • 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.
  • One may accomplish this by encapsulating the script in a Jenkins task.
  • As an extensible automation server, Jenkins can be used as a simple
    CI server or turned into the continuous delivery hub for any project.

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. In March 2019 the Linux Foundation, along with CloudBees, Google, and a number of other companies, launched a new open source software foundation called the Continuous Delivery Foundation (CDF). Jenkins contributors decided that their project should join this new foundation. Kawaguchi wrote at the time that nothing of significance would change for users.

Kohsuke open sourced it, creating the Jenkins project, and soon Jenkins usage had spread around the world. 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.

Jenkins builds and tests our software projects, which continuously making it easier for developers to integrate changes to the project, and making it easier for users to obtain a fresh build. Instead, developers need to keep their eyes out only on the smaller fragment of code they committed. This accelerates development and helps in rolling out more application releases faster. The next significant advantage is that Jenkins handles all the heavy-duty labor that must be undertaken in parallel when a build is made.

Once it senses a commit from any developer, the process mentioned above is repeated. Continuous Integration is a development practice in which the developers are required to commit changes to the source code in a shared repository several times a day or more frequently. Pipelines automate testing and reporting on isolated changes in a larger code base in real time and facilitates the integration of disparate branches of the code into a main branch. This definition only describes the upstream open source project. Jenkins is a powerful application that allows continuous integration and continuous delivery of projects, regardless of the platform you are working on.

Remember that Jenkins does not support federation between servers, which may cause performance problems. Next, the contents of Jenkins are saved locally in a Jenkinsfile as plain text. The Jenkinsfile has a curly bracket syntax that resembles JSON. Pipeline steps are enclosed in curly brackets and specified as commands with arguments.


This makes it a promising tool for both new and experienced DevOps professionals. Jenkins is an open-source automation platform that enables a digital application’s continuous development and deployment. It is written in Java and has plugins that cater to various facets and characteristics of continuous integration. It can help enterprises accelerate their software or app development initiatives significantly.

The Test Score Rating examines how students at this school performed on standardized tests compared with other schools in the state. The Test Rating was created using 2022 Florida End Of Course Test (EOC) data from Florida Department of Education, and using 2022 Florida Standards Assessment data from Florida Department of Education. It is obvious from the above stated problems that not only the software delivery process became slow but the quality of software also went down. Let us imagine, that there are around 10 developers who are working on a shared repository. Some developer completes their task in 25 days while others take 30 days to complete.

Best Practices for Jenkins Pipeline

It helps automate the parts of software development related to building, testing, and deploying, facilitating continuous integration and continuous delivery. It is a server-based system that runs in servlet containers such as Apache Tomcat. Jenkins is an open-source automation tool written in Java with plugins built for continuous integration.

With Jenkins, organizations can accelerate the software development process by automating it. Jenkins manages and controls software delivery processes throughout the entire lifecycle, including build, document, test, package, stage, deployment, static code analysis and much more. Jenkins is a Java-based open-source automation platform with plugins designed for continuous integration. It is used to continually create and test software projects, making it easier for developers and DevOps engineers to integrate changes to the project and for consumers to get a new build. It also enables you to release your software continuously by interacting with various testing and deployment methods.

Jenkins automation

Plugins use their own set of Java Annotations and design patterns that define how the plugin is instantiated, extension points, the function of the plugin and the UI representation in the Jenkins Web UI. Plugin development also makes use of Maven deployment to Jenkins. They help extend Jenkins capabilities and integrated Jenkins with other software. Plugins can be downloaded from the online Jenkins Plugin repository and loaded using the Jenkins Web UI or CLI. Currently, the Jenkins community claims over 1500 plugins available for a wide range of uses.

It is a server-based application and requires a web server like Apache Tomcat. The reason Jenkins software became so popular is that of its monitoring of repeated tasks which arise during the development of a project. For example, if your team is developing a project, Jenkins will continuously test your project builds and show you the errors in early stages of your development. With Jenkins, organizations can accelerate the software development process through automation. Jenkins integrates development life-cycle processes of all kinds, including build, document, test, package, stage, deploy, static analysis, and much more.

Advantages of using Jenkins

With the help of Dashboard, we can configure the jobs/projects but the build takes place in Nodes/Slave. By default one node (slave) is configured and running in Jenkins server. We can add more nodes using IP address, user name and password using the ssh, jnlp or webstart methods. Jenkins is an open source automation tool written in Java programming language that allows continuous integration.
