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.

Introduction to AWS CloudFormation


AWS CloudFormation is a managed AWS service that allows you to define AWS services and resources using infrastructure as code, and is an alternative to using the AWS console, CLI, or various SDKs for deploying your AWS infrastructure. Although there is bit of a learning curve to master CloudFormation, once you have the basics of using CloudFormation under your belt, it represents an extremely powerful approach to deploying your AWS infrastructure, particularly once you start deploying complex environments. 

When using CloudFormation, you define one or more resources in a CloudFormation template, which is a convenient mechanism to group related resources in a single place. When you deploy your template, CloudFormation will create a stack that comprises the physical resources defined in your template. CloudFormation will deploy each resource, automatically determining any dependencies between each resource, and optimise the deployment so that resources can...
