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: An RDS instance requires you to create a DB subnet group with at least two subnets.
  2. When configuring an Application Load Balancer, which component services frontend connections from end users?
  3. True/False: A target group can accept registrations from targets before the Application Load Balancer listener is created.
  4. When configuring security group rules permitting access between an application database and ECS container instances, you receive a CloudFormation error about circular dependencies. What type of resources can you use to overcome this issue?
  5. You configure an ECS task definition that includes two container definitions. One of the container definition performs a short provisioning task and then exits. You discover that ECS is continuously restarting ECS services based on this task definition. How can you resolve this issue?
  6. Which CloudFormation parameter can you configure to define explicit dependencies on other resources?
  7. True/False: CloudFormation custom resources...
