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.

Chapter 4, Introduction to ECS


  1. ECS cluster, ECS task definition, and ECS service.
  2. True.
  3. YAML.
  4. False – when using static port mappings, you can only have one instance of a given static port mapping per ECS container instance (assuming a single network interface).
  5. False – the ECS CLI is recommended for sandbox/test environments only.
  6. You would create an ECS task.
  7. False – ECS task definitions are immutable and a given revision of a task definition cannot be modified.  You can, however, create a new revision of a given ECS task definition that is based off the previous revision but includes changes.
  8. False – you need to run curl localhost:51678/v1/metadata.
