You probably have not noticed this, but so far, all of the Docker workstation deployments, or nodes that we have used in our examples have been run in single-engine mode. What does that mean? Well, it tells us that the Docker installation is managed directly and as a standalone Docker environment. While this is effective, it is not very efficient and it does not scale well. Of course, Docker understands the limitations and has provided a powerful solution to this problem. It is called Docker swarm. Docker swarm is a way to link Docker nodes together, and manage those nodes and the dockerized applications that run on them efficiently and at scale. Simply stated, a Docker swarm is a group of Docker nodes connected and managed as a cluster or swarm. Docker swarm is built into the Docker engine, so no additional installation is required to use it. When a Docker...

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.
