Deploying Docker Containers in Amazon ECS using Fargate
Posted : October 11th, 2018

AWS Fargate lets you run containers without managing servers or clusters. This article is a guide to deploying a simple “Hello World!” Docker Container in Amazon ECS using Fargate. The container we’ll use is available here, built using this Dockerfile. We’ll create the following ECS Objects:

  • Container Definition specifies the Docker Image to use for the container, along with its port mappings, environment, network settings, resource limits, etc.
  • Task Definition is a blueprint for your application, & specifies which containers are included in your task, how they interact with each other & what resources they use. You can also specify data volumes for your containers to use.
  • Service lets you run & maintain a specified number (the “desired count”) of simultaneous instances of a task definition in a cluster.
  • Cluster is a regional grouping of one or more container instances on which you can run task requests.

We start at the ECS Console at Click Create Cluster:

Select the Fargate template & click Next:

Enter Cluster Name, select Create VPC & click Create:
