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, which allows you to run Jenkins slaves in Kubernetes' pods.
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/.
Running it from the Docker CLI is as simple as this:
docker run --name myjenkins -p 8080:8080 -v /var/jenkins_home jenkins
Log in to your Jenkins server, and from your home dashboard, click on Manage Jenkins. Then, select Manage Plugins from the list.
