Docker on Amazon Web Services

By: Justin Menga

Overview of this book

Over the last few years, Docker has been the gold standard for building and distributing container applications. Amazon Web Services (AWS) is a leader in public cloud computing, and was the first to offer a managed container platform in the form of the Elastic Container Service (ECS). Docker on Amazon Web Services starts with the basics of containers, Docker, and AWS, before teaching you how to install Docker on your local machine and establish access to your AWS account. You'll then dig deeper into the ECS, a native container management platform provided by AWS that simplifies management and operation of your Docker clusters and applications for no additional cost. Once you have got to grips with the basics, you'll solve key operational challenges, including secrets management and auto-scaling your infrastructure and applications. You'll explore alternative strategies for deploying and running your Docker applications on AWS, including Fargate and ECS Service Discovery, Elastic Beanstalk, Docker Swarm and Elastic Kubernetes Service (EKS). In addition to this, there will be a strong focus on adopting an Infrastructure as Code (IaC) approach using AWS CloudFormation. By the end of this book, you'll not only understand how to run Docker on AWS, but also be able to build real-world, secure, and scalable container platforms in the cloud.

Docker Swarm introduction


Docker Swarm is a native integrated feature of the Docker Engine, providing cluster management and container orchestration features that allow you to run Docker containers at scale in production. Every Docker Engine running version 1.13 or greater includes the ability to operate in swarm mode, which provides the following features:

  • Cluster management: All nodes operating in swarm mode include native cluster features that allow you to quickly establish clusters that you can deploy your applications to.
  • Multi-host networking: Docker supports overlay networking that allows you to create virtual networks over which all containers attached to the network can communicate privately. This networking layer is completely independent of the physical networking topology that connects your Docker Engines, meaning you typically don't have to worry about traditional networking constraints such as IP addressing and network segmentation—Docker takes care of all of this for you.
  • Service...
