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.

Executing continuous integration inside containers

The first stage in our continuous deployment pipeline will contain quite a few steps. We'll need to check out the code, to run unit tests and any other static analysis, to build a Docker image, and to push it to the registry. If we define CI as a set of automated steps followed with manual operations and validations, we can say that the steps we are about to execute can be qualified as CI.

The only thing we truly need to make all those steps work is Docker client with the access to Docker server. One of the containers of the cd Pod already contains it. If you take another look at the definition, you'll see that we are mounting Docker socket so that the Docker client inside the container can issue commands to Docker server running on the host. Otherwise, we would be running Docker-in-Docker, and that is not a very good...
