Jenkins is an open-source automation server that helps developers build, test and deploy their software projects. It is a popular tool for continuous integration and continuous delivery (CI/CD) pipeline. Jenkins allows developers to automate the building, testing, and deployment of their code, making the software development process more efficient and streamlined. It is widely used by software development teams of all sizes to automate the software development process and improve collaboration among team members. With Jenkins, developers can easily build, test and deploy their code, track bugs, and manage the entire software development lifecycle. In this guide, we will be covering the process of setting up a Jenkins server on an Ubuntu machine.
