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.

Ansible with Docker and Kubernetes

As you may have noticed, Ansible and Docker (along with Kubernetes) address similar software deployment issues:

  • Environmental configuration: Both Ansible and Docker provide a way to configure the environment; however, they use different means. While Ansible uses scripts (encapsulated inside the Ansible modules), Docker encapsulates the whole environment inside a container.
  • Dependencies: Ansible provides a way to deploy different services on the same or different hosts and lets them be deployed together. Kubernetes has similar functionality, which allows for running multiple containers at the same time.
  • Scalability: Ansible helps to scale the services providing the inventory and host groups. Kubernetes has similar functionality to automatically increase or decrease the number of running containers.
  • Automation with configuration files: Docker, Kubernetes, and Ansible store the whole environmental configuration...
