Jenkins is a platform for creating a Continuous Integration/Continuous Delivery (CI/CD) environment. It is written in Java and provides support for various version control tools such as Git, running Bash scripts and Windows batch files, building Ant and Apache Maven-based projects, and more. Jenkins helps build, test, and continually deploy software. It is an open-source system and one of the leading automation servers. Jenkins requires scripting some automation steps, but it provides a fast and robust way to systematize the software development lifecycle. The program runs web containers and plugins, such as Apache Tomcat, and helps manage lifecycle and access rights requests. Over 1700 plugins for Jenkins enrich the software integration, automation, and delivery processes and provide a customizable environment. Jenkins is used for the whole software delivery pipeline, including deployment.
