Case Study on Jenkins

What is Jenkins?

Jenkins offers a simple way to set up a continuous integration or continuous delivery (CI/CD) environment for almost any combination of languages and source code repositories using pipelines, as well as automating 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.

How Jenkins works?

Jenkins is distributed as a WAR archive and as 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.
