The DevOps 2.4 Toolkit

By: Viktor Farcic

Overview of this book

Building on The DevOps 2.3 Toolkit: Kubernetes, Viktor Farcic brings his latest exploration of the Docker technology as he records his journey to continuously deploying applications with Jenkins into a Kubernetes cluster. The DevOps 2.4 Toolkit: Continuously Deploying Applications with Jenkins to a Kubernetes Cluster is the latest book in Viktor Farcic’s series that helps you build a full DevOps Toolkit. This book guides readers through the process of building, testing, and deploying applications through fully automated pipelines. Within this book, Viktor will cover a wide-range of emerging topics, including an exploration of continuous delivery and deployment in Kubernetes using Jenkins. It also shows readers how to perform continuous integration inside these clusters, and discusses the distribution of Kubernetes applications, as well as installing and setting up Jenkins. Work with Viktor and dive into the creation of self-adaptive and self-healing systems within Docker.

Did we do it?

We only partially succeeded in defining our continuous deployment stages. We did manage to execute all the necessary steps.

Once we confirmed that the application works as expected, we updated production with the new release. The new release was deployed through rolling updates but, since it was the first release, we did not see the effect of it. Finally, we run another round of tests to confirm that rolling updates were successful and that the new release is integrated with the rest of the system.

You might be wondering why I said that "we only partially succeeded." We executed the full pipeline. Didn't we?

One of the problems we're facing is that our...
