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.

ECS architecture


ECS is an AWS-managed service that provides you with core building blocks to construct how you want to deploy and operate container applications in AWS.

Note

Prior to December 2017, the Elastic Container Service was known as the EC2 Container Service.

ECS allows you to:

  • Build and publish your Docker images in private repositories
  • Create definitions that describe the container images, configuration, and resources required to run your applications
  • Launch and run your containers using your own EC2 infrastructure or using an AWS-managed infrastructure
  • Manage and monitor your containers
  • Orchestrate rolling deployments of new versions or revisions of your container applications

To provide these capabilities, ECS includes a number of components illustrated in the following diagram and described in the following table:
