Amazon Fargate Quick Start Guide

By: Deepak Vohra

Overview of this book

Amazon Fargate is new launch type for the Amazon Elastic Container Service (ECS). ECS is an AWS service for Docker container orchestration. Docker is the de facto containerization framework and has revolutionized packaging and deployment of software. The introduction of Fargate has made the ECS platform serverless. The book takes you through how Amazon Fargate runs ECS services composed of tasks and Docker containers and exposes the containers to the user. Fargate has simplified the ECS platform. We will learn how Fargate creates an Elastic Network Interface (ENI) for each task and how auto scaling can be enabled for ECS tasks. You will also learn about using an IAM policy to download Docker images and send logs to CloudWatch. Finally, by the end of this book, you will have learned about how to use ECS CLI to create an ECS cluster and deploy tasks with Docker Compose.

Amazon ECS is a managed service for containerized applications based on Docker containers. Managed service implies that ECS manages all container orchestration aspects including launching a cluster of virtual machines (EC2 instances), creating and scheduling containers on the virtual machines, and scaling the cluster of VMs.

ProblemAmazon ECS runs Docker containers on virtual machines (EC2 instances). The EC2 launch type incurs an overhead of launching and managing a cluster of virtual machines (EC2 instances). As a primer on ECS, a task definition defines a group of containers (container definitions). A container definition defines a name, Docker image, port mappings, entry point, and command. Resources (CPU and memory) are defined at both the task and container level. A service definition defines a service and consists of a task definition, launch type, load balancers, network configuration, deployment configuration, and deployments. The ECS cluster with the EC2...
