source for learning

Jenkins has become a must-have in today’s world of Agile and DevOps for both Java programmers and DevOps experts. Using Jenkins, Continuous Integration (CI) and Continuous Deployment (CD) pipelines can be built, decreasing software development and delivery risk.

It means that the development and deployment process will be simple. As soon as a change is made to a source control system like Git, Jenkins can begin creating artifacts and running unit tests, resulting in faster feedback. As a disruptive force in software development and operations, it ranks high on the fascinating technologies of the last decade. 

Several top-rated Jenkins training providers provide courses coupled with Jenkins Certification to help you work smarter with Jenkins, whether you’re interested in learning Jenkins pipeline scripts or integrating CI with Jenkins into your DevOps strategy. Let’s find out which free resources are excellent for beginners to learn Jenkins.

What is Jenkins? Why do we need it?

Jenkins is a Java-based open-source automation platform with Continuous Integration plugins. Jenkins ‘ primary goal is to help developers incorporate changes into the project and assist users in getting a fresh build. Additionally, it allows you to keep delivering your product by interacting with a wide range of testing and deployment platforms.

Jenkins can help organizations speed up the software development process. For example, Jenkins may build, document, test, package (stage), stage (deploy), and perform static analysis.

You can achieve continuous Integration with the aid of plugins in Jenkins. Plugins allow for the Integration of various DevOps stages. When integrating a specific tool, you must first install the plugins for that tool. For instance, there’s Git, Maven 2, Amazon EC2, and HTML publisher.

Advantages of using Jenkins

Jenkins is run by a community that is quite welcoming. Public meetings are held once a month to solicit feedback from the general public on the development of the Jenkins project.

About 280 issues have been resolved, and the project releases a stable version every three months. As technology advances, Jenkins adapts to it. The plugins database of Jenkins now has roughly 320 published plugins. Jenkins is even more powerful and feature-rich than it already is with plugins.

Additionally, the cloud-based design of the Jenkins tool allows you to run Jenkins on cloud-based platforms. Jenkins’ popularity can be attributed to the fact that it was developed by and for developers.

Disadvantages of using Jenkins

  • Even though Jenkins is a vital tool, it has its limitations.
  • Its UI is outdated and unintuitive compared to current trends in user interface design.
  • Many developers enjoy using Jenkins, but it isn’t easy to maintain because it operates on a server and requires some knowledge of server administration to keep track of its activities.
  • The difficulty of installing and configuring Jenkins is one of the reasons why many people do not use it.
  • It is prevalent for continuous integrations to fail because of a few minor configuration changes.
