How to install a Jenkins instance with Helm

Kubernetes is a popular platform for hosting Docker containers, offering features such as advanced orchestration, networking, security, and volume management. Helm, a tool for Kubernetes, provides package management functionality, and its charts can be used to deploy applications like Jenkins. The text explains how to deploy Jenkins on Kubernetes using Helm, detailing the necessary prerequisites, including a Kubernetes cluster and Helm client. It covers deploying a Jenkins instance with default settings, exposing Jenkins through a public IP, installing additional plugins, configuring Jenkins through Jenkins Configuration as Code (JCasC), and backing up Jenkins volumes. The text also outlines creating dynamic Jenkins agents within the cluster, which are deployed and destroyed as tasks are scheduled and completed. This setup allows for scalable and responsive build environments, leveraging Kubernetes' capabilities for elastic workloads.
