description Jenkins Kubernetes Plugin Overview

The Jenkins Kubernetes Plugin facilitates continuous integration and delivery workflows for applications deployed within Kubernetes environments. It integrates directly into existing Jenkins pipelines, automating processes such as image building, testing, and deployment to dynamic clusters. This plugin is valuable for DevOps teams and developers managing containerized applications on platforms like Google Kubernetes Engine or Amazon Elastic Kubernetes Service.

help Jenkins Kubernetes Plugin FAQ

What does the Jenkins Kubernetes plugin actually do?

The plugin integrates Jenkins with a Kubernetes cluster by dynamically provisioning ephemeral Jenkins agent pods to run CI/CD pipeline tasks. Instead of using static build servers, it spins up a new, isolated container for each build to ensure a clean environment.

Do I need a persistent agent when using the Jenkins Kubernetes plugin?

No, the main advantage of this plugin is that it eliminates the need for a persistent, always-on Jenkins agent node. It automatically scales the number of active agents up or down based on the current workload of your Jenkins CI/CD pipelines.

Can I define custom container images for my Jenkins Kubernetes agents?

Yes, you can specify a custom Docker container image for the Jenkins agent directly within your Jenkinsfile or pod template configuration. This allows you to use different environments, such as a Python image for one stage and a Node.js image for the next.

How does the Jenkins Kubernetes plugin handle workspace volumes?

Since agents are ephemeral, the plugin typically uses ephemeral storage by default, but it fully supports mounting persistent volumes or host paths. You can configure volume mounts in the pod template so that data persists or is shared between pipeline stages as needed.
