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 KMS keys


A key building block of any secrets management solution is the ability to encrypt your credentials using encryption keys, which ensures the privacy and confidentiality of your credentials. The AWS Key Management Service (KMS) is a managed service that allows you to create and control encryption keys, and provides a simple, low-cost solution that takes away many of the operational challenges of managing your encryption keys. Key features of KMS include centralized key management, compliance with a number of industry standards, built-in auditing and integration with other AWS services.

When building a secrets management solution that uses AWS Secrets Manager, you should create, at a minimum, at least one KMS key in your local AWS account and region that is used to encrypt your secrets. AWS does provide a default KMS key that you can use with AWS Secrets Manager, so this is not a strict requirement, however, in general, you should be comfortable with creating your own KMS keys...
