Module 7 of Path: DevOps for Developers
Jenkins X with Kubernetes
Module Overview
Jenkins X is a powerful tool for providing software developers continuous integration, automated testing, and continuous delivery, known as CI/CD, in Kubernetes. It’s no secret that Kubernetes is extremely complex, and Jenkins X helps you by simplifying processes into concepts that can be adopted quickly and without spending months trying to figure out “the right way to do stuff.” In this course, you’ll start by exploring the inner workings of Jenkins X and how to create a cluster using it. You’ll then learn how to combine Jenkins X with tools you’re already using. Throughout, you’ll see how this exciting new tool changes how you work with Kubernetes. By the time you’re done, you will be confident managing CI/CD using Jenkins X in a Kubernetes cluster.
