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.

Questions


  1. True/False: The KMS service requires you to supply your own private key information.
  2. What feature of KMS allows you to specify a logical name for your key, rather than the UUID-based identifier of the key?
  3. You want to avoid manually configuring the ARN of a KMS key that you use in multiple CloudFormation stacks.  Assuming you defined the KMS key in a separate CloudFormation stack, what CloudFormation feature can you use to solve this problem?
  4. True/False: When you delete a secret from AWS Secrets Manager you can never recover the secret.
  5. Which tools would you typically use in an entrypoint script to retrieve a secret from AWS Secrets Manager and transform the key/value pairs in the secret to be suitable for exporting to the container environment?
  6. You receive an error in a container entrypoint script indicating you do not have sufficient permissions to access a secret.  You check the IAM role and confirm it has a single permission secretsmanager:GetSecretValue allowed for the secret....
