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.

Configuring an ECS service for Fargate


Now that you have defined an ECS task definition for Fargate, you can create an ECS service that will reference your ECS task definition and deploy one or more instances (ECS tasks) for your service. 

As you might expect, when configuring ECS services to support Fargate, there are some key considerations that you need to be aware of:

  • Launch type: You must specify Fargate as the launch type for any ECS service that you want to run using Fargate.
  • Platform version: AWS maintains different versions of the Fargate runtime or platform, which will evolve over time, and may at some point introduce breaking changes for your ECS services. You can optionally target a specific platform version for your ECS service, or simply omit configuring this property, to use the latest platform version available.
  • Network configuration: Because Fargate requires the use of awsvpc networking mode, your ECS services must define a network configuration that defines the subnets your...
