Docker Quick Start Guide

By: Earl Waud

Overview of this book

Docker is an open source software platform that helps you with creating, deploying, and running your applications using containers. This book is your ideal introduction to Docker and containerization. You will learn how to set up a Docker development environment on a Linux, Mac, or Windows workstation, and learn your way around all the commands to run and manage your Docker images and containers. You will explore the Dockerfile and learn how to build your own enterprise-grade Docker images. Then you will learn about Docker networks, Docker swarm, and Docker volumes, and how to use these features with Docker stacks in order to define, deploy, and maintain highly-scalable, fault-tolerant multi-container applications. Finally, you will learn how to leverage Docker with Jenkins to automate the building of Docker images and the deployment of Docker containers. By the end of this book, you will be well prepared when it comes to using Docker for your next project.

Using Docker containers for your Jenkins build nodes

To use Docker containers for the Jenkins build agents, you need to do a few things to your Jenkins configuration:

  • Build a new Docker image that can act as a Jenkins build agent, and is capable of building Docker images (of course)
  • Push the new image to a Docker registry
  • Turn off the default Jenkins build agents
  • Install the Docker plugin for Jenkins
  • Configure a new cloud to enable Dockerized build agents

Building the Docker image

Let's get started. The first thing we want to do is build our specialized Docker image that can be used for our Jenkins agents. To do this, we are going to use the skills we learned in Chapter 3, Creating Docker Images, to create Docker images...
