Continuous Delivery with Docker and Jenkins

By: Rafał Leszko

Overview of this book

The combination of Docker and Jenkins improves your Continuous Delivery pipeline using fewer resources. It also helps you scale up your builds, automate tasks and speed up Jenkins performance with the benefits of Docker containerization. This book will explain the advantages of combining Jenkins and Docker to improve the continuous integration and delivery process of 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 Docker Swarm. Next, you will get to know how to deploy applications using Docker images and testing them with Jenkins. By the end of the book, you will be enhancing the DevOps workflow by integrating the functionalities of Docker and Jenkins.

Exercises

You've learned a lot about how to configure the Continuous Integration process. Since practice makes man perfect, we recommend doing the following exercises:

  1. Create a Python program that multiplies two numbers passed as the command-line parameters. Add unit tests and publish the project on GitHub:
  1. Build the Continuous Integration pipeline for the Python calculator project:
    • Use Jenkinsfile for specifying the pipeline
    • Configure the trigger so that the pipeline runs automatically in case of any commit to the repository
    • The pipeline doesn't need the Compile step since Python is an interpretable language
    • Run the pipeline and observe the results
    • Try to commit the code that breaks each stage...
