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.

Deployment overview


The goal of the next two chapters is to establish the supporting infrastructure and resources to deploy Docker applications using AWS. In the spirit of the best practice of defining your infrastructure as code, you will be defining a CloudFormation template that will include all AWS resources required to support your Docker applications running in ECS. As you progress through each chapter, you will build on this template, slowly but surely adding more and more resources until you have a complete solution for deploying your Docker applications in AWS using ECS.

With this in mind, the focus of this chapter is to learn how to build ECS clusters using CloudFormation, and as you have already learned in previous chapters, an ECS cluster is a collection of ECS container instances that you can target when you run an ECS service or ECS task.

ECS clusters themselves are very simple constructs - they simply define a collection of ECS container instances and a cluster name. How these...
