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.

Running functional tests

Which steps do we need to execute in the functional testing phase? We need to deploy the new release of the application. Without it, there would be nothing to test. All the static tests were already executed when we built the image, so everything we do from now on will need a live application.

Deploying the application is not enough, we'll have to validate that at least it rolled out successfully. Otherwise, we'll have to abort the process.

We'll have to be cautious how we deploy the new release. Since we'll run it in the same cluster as production, we need to be careful that one does not affect the other. We already have a Namespace that provides some level of isolation. However, we'll have to be attentive not to use the same path or domain in Ingress as the one used for production. The two need to be accessible separately from...
