AWS ECS Container Autoscale Lambda function: Create a CloudWatch CPU metric for high and low alarms. Create SNS topics to trigger from each alarm. Subscribe the lambda function to the SNS topics. Let magic happen.
console.log('Loading event');
//Import AWS-SDK
var AWS = require('aws-sdk');
//Fetch the assigned cpu requirements for a task definition
var fetchRequiredCPU = function(taskDefinitionData)
{
var cpu = taskDefinitionData.taskDefinition.containerDefinitions[0].cpu;
return cpu;
};
