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.

Automating the workflow

At this point, you have managed to successfully configure Docker Compose to build, test, and create a working local environment for the sample application, complete with MySQL database integration and acceptance tests.  You can now stand up this environment with a handful of commands, but even though using Docker Compose has significantly simplified the commands you need to run, it is still difficult to remember which commands to use and in which order. Ideally we want a single command to run the complete workflow, and this is where a tool such as GNU Make is very useful.

Make has been around a long time, and is still considered the build tool of choice for many C and C++ applications. Task automation is a key feature of Make, and the ability to define tasks or targets in a simple format that can be invoked with a single command has made Make a popular automation tool, particularly when dealing with Docker containers.

By convention make looks for a file, called Makefile...
