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 production tests

The process for running production tests is the same as functional testing we executed earlier. The difference is in the tests we execute, not how we do it.

The goal of production tests is not to validate all the units of our application. Unit tests did that. It is not going to validate anything on the functional level. Functional tests did that. Instead, they are very light tests with a simple goal of validating whether the newly deployed application is correctly integrated with the rest of the system. Can we connect to the database? Can we access the application from outside the cluster (as our users will)? Those are a few of the questions we're concerned with when running this last round of tests.

The tests are written in Go, and we still have the golang container running. All we have to do it to go through the similar steps as before.
