stack-status v0.0.3

Stack-Status

A NodeJS app for gathering data from ELB, EC2 and CloudWatch to aggregate them to show the status of a stack.

This is used for a specific cloud setup where custom tags are used in the naming of EC2 instances which are consistant.

Will be adding other API's for Redshift, ElasticSearch and other servcies soon.

Install

npm i stack-status --S

Config

const config = {
  region: '', // aws region
  secretAccessKey: '', // aws secretAccessKey
  accessKeyId: '', // aws accessKeyId
  name: '', // aws tag for instance name
  env: '', // aws tag for enviroment
};

Construct the class

const stack = new Stack(config);
