Continuous Delivery with Docker and Jenkins - Second Edition

By: Rafał Leszko

Overview of this book

Continuous Delivery with Docker and Jenkins, Second Edition will explain the advantages of combining Jenkins and Docker to improve the continuous integration and delivery process of an app development. It will start with setting up a Docker server and configuring Jenkins on it. It will then provide steps to build applications on Docker files and integrate them with Jenkins using continuous delivery processes such as continuous integration, automated acceptance testing, and configuration management. Moving on, you will learn how to ensure quick application deployment with Docker containers along with scaling Jenkins using Kubernetes. Next, you will get to know how to deploy applications using Docker images and testing them with Jenkins. Towards the end, the book will touch base with missing parts of the CD pipeline, which are the environments and infrastructure, application versioning, and nonfunctional testing. By the end of the book, you will be enhancing the DevOps workflow by integrating the functionalities of Docker and Jenkins.

Introducing configuration management


Configuration management is the process of controlling configuration changes in a way such that the system maintains integrity over time. Even though the term did not originate in the IT industry, currently, it is broadly used to refer to the software and the hardware. In this context, it concerns the following aspects:

  • Application configuration: This involves software properties that decide how the system works, which are usually expressed in the form of flags or properties files passed to the application; for example, the database address, the maximum chunk size for file processing, or the logging level. They can be applied during different development phases: build, package, deploy, or run.
  • Infrastructure configuration: This involves server infrastructure and environment configuration, which takes care of the deployment process. It defines what dependencies should be installed on each server and specifies the way applications are orchestrated (which...
