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

While UIs are nice to look at, I am a firm believer that nothing beats the command line concerning speed and repeatability. Fortunately, we can retrieve almost any information related to Jenkins X through `jx` executable.
## Retrieving activities
We can, for example, get the last activities (builds) of those jobs.

We can see that there were activities with each of the three jobs. We had one deployment to the production environment (`environment-jx-rocks-production`), and two deployments to staging (`environment-jx-rocks-staging`). The first build (activity) is always performed when a job is created. Initially, environments only contain a few applications necessary for their correct operation. The reason for the second build of the staging environment lies in the creation of the *jx-go* project. One of the steps in its pipeline is in charge of promoting a successful build to the staging environment automatically. When we explore jenkins-x.yml in more detail, you'll get a better understanding of the process, including promotions.

The last activity is of the *jx-go* pipeline. So far, we did not push any change to the repository, so we have only one build that was run when the job itself was generated through the quickstart process.


### Applying filters on activities
Listing the most recent activities is very useful since we have only a few pipelines, but when their number grows, we’ll need to be more specific. For example, we might want to retrieve only the activities related to the *jx-go* pipeline.



While UIs are nice to look at, I am a firm believer that nothing beats the command line concerning speed and repeatability. Fortunately, we can retrieve almost any information related to Jenkins X through `jx` executable.

This lesson explores how we can retrieve information concerning Jenkins X through the command line and the initial GitHub release created by Jenkins X.
