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 8. Deploying Applications Using ECS

In the previous chapter, you learned how to configure and deploy ECS clusters in AWS using EC2 Auto Scaling groups, and the goal of this chapter is to deploy ECS applications to your newly built ECS cluster using CloudFormation.

You will first get started learning how to define and deploy the various supporting resources that are typically required for ECS applications in a production-grade environment. These resources include creating an application database to store data for your application, deploying application load balancers to service and load balance requests to your application, and configuring other resources, such as IAM roles and security groups, that control access to and from your application.

With these supporting resources in place, you will proceed to create ECS task definitions that define the run-time configuration of your containers and then configure ECS services that deploy your ECS task definitions to your ECS clusters, and...
