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.

Defining the functional testing stage

For the functional testing stage, the first step is to install the application under test. To avoid the potential problems of installing the same release twice, we'll use helm upgrade instead of install.

As you already know, Helm only acknowledges that the resources are created, not that all the Pods are running. To mitigate that, we'll wait for rollout status before proceeding with tests.

Once the application is rolled out, we'll run the functional tests. Please note that, in this case, we will run only one set of tests. In the "real" world scenario, there would probably be others like, for example, performance tests or front-end tests for different browsers.

When running multiple sets of different tests, consider using parallel construct. More information can be found in the Parallelism and Distributed Builds with...
