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.

Using the ECS CLI


In this chapter, we have focused solely on using the AWS console to get started with ECS. Another tool that is written and maintained by AWS is called the ECS CLI, which allows you to create ECS clusters and deploy ECS tasks and services from the command line.

The ECS CLI is different from the AWS CLI in a variety of ways, but the main differences include:

  • The ECS CLI is focused on interacting with ECS and only supports interacting with other AWS services that provide supporting resources for ECS, such as the AWS CloudFormation and EC2 service.
  • ECS CLI operations are more coarse-grained than AWS CLI operations. For example, the ECS CLI will orchestrate creating an ECS cluster and all of its supporting resources, much like the behavior of the ECS cluster wizard you used earlier in this chapter, whereas the AWS CLI is focused on more fine-grained operations that perform a single specific task.
  • The ECS CLI is written in Golang, whereas the AWS CLI is written in Python. This does...
