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.

In this chapter, you implemented a Docker workflow that tests, builds, and packages your application into a Docker image that is ready to publish and deploy to production. You learned how you can build your application in two stages using Docker multi-stage builds—the test stage uses a development environment complete with development libraries and source compilation tools that allows you to build and test your application and its dependencies in precompiled packages, while the release stage takes those built packages and installs them into a production-ready operating environment, free of development libraries and other tools, significantly reducing the attack surface of your application.

You learned how you to use Docker Compose to help simplify the various commands and actions you need to perform during the test and release stages, creating a docker-compose.yml file with a number of services, each defined in a declarative, easy-to-understand format. You learned how to replicate...
