Description

Introduction

Jenkins X is an open-source, cloud-native CI/CD solution designed specifically for Kubernetes. It automates the process of continuous integration and continuous delivery, allowing teams to build, test, and deploy applications quickly and efficiently in Kubernetes environments. By leveraging Kubernetes, Jenkins X simplifies the process of managing pipelines, scaling applications, and automating deployments. With built-in support for GitOps and the use of Kubernetes-native resources, Jenkins X enables teams to implement modern DevOps practices with minimal configuration.

Prerequisites

• Basic understanding of Continuous Integration and Continuous Delivery (CI/CD) concepts.
• Familiarity with Kubernetes, Docker, and containerized applications.
• Basic knowledge of Git and GitOps.
• Familiarity with Jenkins, GitHub/GitLab, and cloud-native development.
• Access to a Kubernetes cluster or a managed Kubernetes service (e.g., Google Kubernetes Engine, Azure Kubernetes Service).
• Jenkins X CLI and kubectl installed and configured.
