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.

Creating an application database using RDS


The sample todobackend application includes a MySQL database that is used to persist todo items that are created through the application API. When you first set up and ran the sample application back in Chapter 1, you used a Docker container to provide the application database, however, in production-grade environments, it is generally considered best practice to run databases, and other services that provide persistent storage, on dedicated machines optimized specifically for database and data access operations. One such service in AWS is the relational database services (RDS), which provides dedicated managed instances optimized for providing popular relational database engines, including MySQL, Postgres, SQL Server, and Oracle. RDS is a very mature and robust service, and is very commonly used to support database requirements for both ECS and other applications that are run in AWS.

RDS instances can be configured using CloudFormation. To get started...
