Create a simple API in node and dockerize it

For the demo of microservices, we will create a simple node API. The technology or framework or language doesn’t really matter once we dockerize the api. I chose node simply because its lightweight and I can deploy with least compute.

API

We expose two APIs.

• API endpoint

/info

{
   "id":"34caea30-acbd-11e8-9861-138b18ec2ca2",  => Random id which uniquely identifies the runnaing instance. 
   "version":"1"  => Version of the api. 
}

• Health endpoint

/health

{
   "status":"OK"
}

Code

Checkout the code from github

Follow the instructions in the readme to build image and run containers.

To keep the memory footprint small, we chosse the base docker image FROM node:8-slim. Please see more information on this here

Push the image to Amazon Elastic Container Registry (ECR)
