Learn how to use Jenkins X to automate your pipeline and achieve CI/CD.

DevOps for Developers

Jenkins X is a powerful tool for providing software developers continuous integration, automated testing, and continuous delivery, known as CI/CD, in Kubernetes.

It’s no secret that Kubernetes is extremely complex, and Jenkins X helps you by simplifying processes into concepts that can be adopted quickly and without spending months trying to figure out “the right way to do stuff.”

In this course, you’ll start by exploring the inner workings of Jenkins X and how to create a cluster using it. You’ll then learn how to combine Jenkins X with tools you’re already using. Throughout, you’ll see how this exciting new tool changes how you work with Kubernetes.

By the time you’re done, you will be confident managing CI/CD using Jenkins X in a Kubernetes cluster.

Jenkins X with Kubernetes

This was a very short chapter, *wasn't it?* There is not much more to learn about manual promotions. All we have to do is execute a single command.

Keep in mind that there are many other things we could do to improve deployment to production. We could add **HorizontalPodAutoscaler** that will scale the application depending on memory and CPU consumption or based on custom metrics. We could also add additional tests beyond those we added in the [Applying GitOps Principles](https://www.educative.io/courses/devops-toolkit-working-with-jenkins-x/getting-started-with-gitops) chapter. We won't work on any of the many improvements we could do since I assume that you already know how to enhance your Helm charts and how to write tests and add their execution to `jenkins-x.yaml`. What matters is that the process works and it is up to you to change and enhance it to suit your specific needs.

We'll conclude that we explored the whole lifecycle of an application and that our latest release is running in production.
# How to free up the resources?
Now you need to decide whether to continue using the cluster or to destroy it. If you choose to destroy it or to uninstall Jenkins X, you'll find the instructions at the bottom of the Gist you chose at the beginning of this chapter.

If you destroyed the cluster or you uninstalled Jenkins X, please remove the repositories and the local files we created. You can use the commands that follow for that.

> ⚠️ Please replace `[...]` with your GitHub user before executing the commands that follow.



This lesson concludes the discussion regarding this chapter and gives instructions to free up the used resources.
