Simple "hello world" demo using EC2 Container Service

Overview

Demo for Hello World in EC2 Container Service blog post. The blog post describes how to run the demo on ECS. The ecs-hello-world container is on DockerHub for easy deployment to ECS. It uses Ruby 2.1.5 as its Docker Base Image.

Demo

The demo consists of 2 Rake tasks. The client takes in a message and posts a JSON message to a SQS queue.

rake hello:client['hello world!']

Sent: fbe73a51-0684-49de-9195-020c03704c9b

{
  "container": "909fbdc5351e",
  "payload": "hello world!",
  "timestamp": "2015-03-31T09:14:24+02:00"
}

The server polls the queue for messages and outputs them to stdout.

rake hello:server
