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.

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 a 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 a 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 and service dependencies in files (stored in...
