The Kubernetes plugin for Jenkins

One way we can use Kubernetes for our CI/CD pipeline is to run our Jenkins build slaves in a containerized environment. Luckily, there is already a plugin, written by Carlos Sanchez, that allows you to run Jenkins slaves in Kubernetes' pods.

Prerequisites

You'll need a Jenkins server handy for this next example. If you don't have one you can use, there is a Docker image available at https://hub.docker.com/_/jenkins/.
