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.

Exercises


In this chapter, we have covered a lot of new aspects for the Continuous Delivery pipeline; to better understand the concept, we recommend you complete the following exercises:

  1. Add a performance test, which 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 test:
    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 that deploys the image into the remote machine
    4. Add the Performance testing stage that executes performance-test.sh
    5. Run the pipeline...
