So far, we have mostly been looking at running a Docker container from a single Docker image, simplifying the Docker model to imagine a world where every application only required a single service, and thus a single Docker image, to run. However, as you know, that is a pretty unrealistic model. Real-world applications are composed of multiple services, and those services are deployed using multiple Docker images. To run all of the necessary containers, and maintain them at the desired number of replicas, handling planned and unplanned downtimes, scaling requirements and all of the other service management needs is a really daunting and complex task. In the recent past, this scenario was handled using a tool called Docker Compose. Docker Compose (as you learned in Chapter 1, Setting up a Docker Development Environment) is an additional tool...

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.
