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

In this chapter, we have covered a lot of new aspects of the CD pipeline. To help you understand these concepts, we recommend that you complete the following exercises:

  1. Add a performance test that tests the hello world service:
    1. The hello world service can be taken from the previous chapter.
    2. Create a performance-test.sh script that makes 100 calls and checks whether the average request-response time is less than 1 second.
    3. You can use Cucumber or the curl command for the script.
  2. Create a Jenkins pipeline that builds the hello world web service as a versioned Docker image and performs performance tests:
    1. Create a Docker build (and Docker push) stage that builds the Docker image with the hello world service and adds a timestamp as a version tag.
    2. Use the Kubernetes deployment from the previous chapters to deploy the application.
    3. Add the Deploy to staging stage, which deploys the image to...
