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.

Summary


In this chapter, you learned how to create an ECS cluster, complete with an EC2 Auto Scaling group and ECS container instances based on a custom Amazon machine image, using an infrastructure-as-code approach to define all resources using CloudFormation.

You learned how an ECS cluster is simply a logical grouping of ECS container instances, and is composed of EC2 Auto Scaling groups that manage a collection of EC2 instances. EC2 Auto Scaling groups can dynamically scale up and down, and you attached an EC2 Auto Scaling launch configuration to your Auto Scaling group, which provides a common collection of settings applied to each new EC2 instance that is added to the group.

CloudFormation provides powerful features for ensuring instances in your Auto Scaling groups are initialized correctly, and you learned how you to configure user data to invoke the CloudFormation helper scripts you installed in your custom machine image, which then download configurable initialization logic defined...
