Continuous Delivery with Docker and Jenkins, 3rd Edition - Third Edition

By: Rafał Leszko

Overview of this book

This updated third edition of Continuous Delivery with Docker and Jenkins will explain the advantages of combining Jenkins and Docker to improve the continuous integration and delivery process of app development. You’ll start by setting up a Docker server and configuring Jenkins on it. Next, you’ll discover steps for building applications and microservices on Dockerfiles and integrating them with Jenkins using continuous delivery processes such as continuous integration, automated acceptance testing, configuration management, and Infrastructure as Code. Moving ahead, you'll learn how to ensure quick application deployment with Docker containers, along with scaling Jenkins using Kubernetes. Later, you’ll explore how to deploy applications using Docker images and test them with Jenkins. Toward the concluding chapters, the book will focus on missing parts of the CD pipeline, such as the environments and infrastructure, application versioning, and non-functional testing. By the end of this continuous integration and continuous delivery book, you’ll have gained the skills you need to enhance the DevOps workflow by integrating the functionalities of Docker and Jenkins.

Exercises

We covered a lot of new material throughout this chapter, so to aid your understanding, I recommend doing the following exercises:

  1. Create a Ruby-based web service, book-library, to store books.

The acceptance criteria are delivered in the form of the following Cucumber feature:

Scenario: Store book in the library
  Given Book "The Lord of the Rings" by "J.R.R. Tolkien" with ISBN number "0395974682"
  When I store the book in library
  Then I am able to retrieve the book by the ISBN number

Proceed as follows:

  1. Write step definitions for the Cucumber test.
  2. Write the web service (the simplest way is to use the Sinatra framework (http://www.sinatrarb.com/), but you can also use Ruby on Rails).
  3. The book should have the following attributes: name, author, and International Standard Book Number (ISBN).
  4. The web service should have the following endpoints:
    • POST /books to add a book
    • GET...
