How can I practice Jenkins

The most crucial aspect of DevOps that is utilized to integrate different DevOps stages is continuous integration. The most well-known Continuous Integration tool is Jenkins.

Jenkins, a free and open-source automation server is Jenkins, can be used by developers to automatically build, integrate, and test code as soon as it is committed to the source repository. This makes it possible for developers to deploy more quickly and find faults and defects sooner.

You will learn about what CI/CD is, what Jenkins is, why we should use Jenkins, how to create pipelines, how to use various plugins, Jenkins Training, and much more in this article, with demonstrations at each step to help you visualize the concepts. You will also get hands-on experience with these concepts to help you build a strong foundation in Jenkins.

What is Jenkins?

Jenkins is a Java-based open-source automation platform with plugins created for continuous integration needs. Jenkins is used to continuously build and test your software projects, making it simpler for developers to incorporate changes to the project and for users to get a new build. By interacting with a wide range of testing and deployment tools, it also enables you to release your software continuously.

Organizations can use Jenkins to automate and speed up the software development process. Jenkins combines all stages of the development lifecycle, including build, document, test, package, stage, deploy, static analysis, and many others.

Plugins assist Jenkins in achieving Continuous Integration. DevOps stages can be integrated thanks to these plugins.

Why Jenkins?

Being free, open-source, and modular, Jenkins is one of the best DevOps tools available and can be integrated with just about every other DevOps tool on the market. Developers can use it to automatically build, integrate, and test code as soon as it is committed to the source repository. This makes it possible for developers to deploy more quickly and find faults and defects earlier. It promotes better developer collaboration by using the most recent code, triggering a build as soon as it is uploaded to the shared repository by any developer, and notifying the developer if the build was successful or not. This prevents developers from wasting time searching for bugs. As a result, Jenkins may be set up on any platform that supports the Java programming language.

What is Continuous Integration?

One of the most crucial aspects of DevOps is continuous integration (CI). It is usually used to combine several DevOps stages. In other words, it’s a coding technique that basically makes it possible for the development team to incorporate minor code modifications and version control techniques relatively regularly.

Continuous integration is typically carried out by having all developers regularly contribute their code to a central repository. It is rather appropriate for a project that needs to be coded and developed using a variety of platforms and technologies. At this time, it is crucial to have a system like this in place to integrate and validate the parallel code modifications.

How is Jenkins used for Continuous Integration?

Jenkins collaborates with a wide range of deployment and testing tools, enabling quicker software delivery. Additionally, by automating processes, the development period is sped up. It needs a web server like Tomcat since it is largely a server-based application.

Jenkins became well-known for its ability to keep track of repetitive chores. Jenkins will continuously check and assess the code when a team is working on a project, returning any potential errors or failures early in the development stage.

How can I practice Jenkins?

The fundamentals of continuous integration with Jenkins training are easy to learn. CI/CD Pipelines with Jenkins certification and training courses on DevOps and Jenkins are specially designed for learning by novices. You will learn about continuous integration, Jenkins architecture, how to establish a Jenkins pipeline, and how to generate a build the CI/CD Pipelines with Jenkins course from Simplilearn. This course will train you in server automation, building pipelines and configuration tools, automated testing and code quality improvement, continuous integration, and distributed systems in Jenkins through highly intensive, hands-on practice assignments. This is the best resource to become an expert in Jenkins in the least amount of time.

How does Jenkins work?

  • The code is first committed to the source code repository by a developer.  In the meantime, Jenkins scans the repository for changes periodically.
  • The Jenkins server quickly discovers the modifications made to the source code repository following a commit. Jenkins will make those modifications and begin setting up a fresh build.
  • The concerned team will be informed if the build fails.
  • Jenkins server deploys the built-in test server if the build is successful.
  • Jenkins server creates feedback following testing and then tells the developers of the build and test results.
  • The entire process keeps repeating as it keeps checking the source code repository for modifications made to the source code.

Benefits of Jenkins

There are numerous advantages to adopting Jenkins, including

  • Jenkins is a tool that is pushed by the community; as a result, there is no corporate interference, it is open source, and anyone can use it without obtaining a license. This implies that a fairly sizable community regularly contributes to it as well. You can always count on someone to create a Jenkins plugin for any new fashionable tool that appears.
  • Another advantage is that you don’t have to pay anything to use it, so whatever you use it for won’t cost you a dime. For those who don’t want to incur additional subscription charges, such as start-ups, small businesses, and individuals, it becomes highly appealing.
  • Jenkins is a flexible and highly configurable tool. It supports an enormous number of plugins. especially when compared to its commercial rivals like Bamboo and Team city, which only offer a few plugins.
  • Any significant platform can run Jenkins without any compatibility problems. It is advantageous in unstable conditions because of this.

Conclusion

As this article on Jenkins draws to a close, recall all the key ideas associated with Jenkins, such as “What is Jenkins?” How do I learn Jenkins? To start learning and to keep the learning ongoing, it is advised to try installing updated plugins and uploading them to the community.

One of the most crucial parts of Jenkins that must be examined is the development of CI/CD pipelines. To gain a deeper working understanding of it, we must now create our own jobs/projects and schedule them using various parameters.
