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 EC2 Key Pair


A key setup task that is required if you are going to running any EC2 instances in your AWS account is to establish one or more EC2 key pairs, which for Linux EC2 instances, can be used to define an SSH key pair that grants SSH access to your EC2 instances.

When you create an EC2 key pair, an SSH public/private key pair will be automatically generated, with the SSH public key being stored as a named EC2 key pair in AWS, and the corresponding SSH private key downloaded to your local client.  If you subsequently create any EC2 instances and reference a named EC2 key pair at instance creation, you will be able to automatically use the associated SSH private key to access your EC2 instances.

Note

SSH access to Linux EC2 instances requires you to use the SSH private key associated with the configured EC2 key pair for the instance, and also requires appropriate network configuration and security groups to permit access to the EC2 instance SSH port from wherever your SSH client...
