+# aws-nuke for Weathertop
+
+AWS Nuke is an open source tool created by [ekristen](https://github.com/ekristen/aws-nuke).
+
+It searches for deleteable resources in the provided AWS account and deletes those which are not considered "Default" or "AWS-Managed", taking your account back to Day 1 with few exceptions.
+
+
+## ⚠ Important
+This is a very destructive tool! It should not be deployed without fully understanding the impact it will have on your AWS accounts.
+Please use caution and configure this tool to delete unused resources only in your lower test/sandbox environment accounts.
+
+## Overview
+
+The code in this repository helps you set up the following architecture:
+
+![infrastructure-overview](architecture-overview.png)
+
+## Feature Outline
+
+1. **Scheduled Trigger**: Amazon EventBridge invokes AWS Step Functions daily.
+2. **Regional Scalability**: Runs AWS CodeBuild projects per region.
+4. **Custom Config**: Pulls resource filters and region targets in [nuke_generic_config.yaml](nuke_generic_config.yaml).
+
+## Prerequisites
+
+1. **AWS-Nuke Binary**: Open-source library from [ekristen](https://github.com/ekristen/aws-nuke) staged in S3.  
+2. **AWS Account Alias**: Must exist in the IAM Dashboard for the target  account.
+8. **Network Connectivity**: Ensure VPC allows downloads from GitHub or stage the binary in S3/artifactory for restricted environments.
+
+## Setup and Installation
+
+* Clone the [repo](https://github.com/ekristen/aws-nuke).
+* Determine the `id` of the account to be deployed for nuking.
+* Narrow [filters](nuke_generic_config.yaml) for the resources/accounts you wish to nuke.
+* Deploy the stack using the below command. You can run it in any desired region.
+```sh
+cdk bootstrap && cdk deploy
+```
+
+Note a successful stack creation, e.g.: 
+
+```bash
+ ✅  NukeCleanser
+
+✨  Deployment time: 172.66s
+
+Outputs:
+NukeCleanser.NukeS3BucketValue = nuke-account-cleanser-config-616362312345-us-east-1-c043b470
+Stack ARN:
+arn:aws:cloudformation:us-east-1:123456788985:stack/NukeCleanser/cfhdkiott-acec-11ef-ba2e-4555c1356d07
+```
+
+Next, run `python upload_job_files.py` to upload two files in this directory: `nuke_config_update.py` and `nuke_generic_config.yaml`.
+
+## When it runs
+* The tool is currently configured to run at a schedule as desired typically off hours 3:00a EST. It can be easily configured with a rate() or cron() expression by editing the cfn template file
+
+* The workflow also sends out a detailed report to an SNS topic with an active email subscription on what resources were deleted after the job is successful for each region which simplifies traversing and parsing the complex logs spit out by the aws-nuke binary. 
+
+* If the workflow is successful, the stack will send out
+  - One email for each of the regions where nuke CodeBuild job was invoked with details of the build execution , the list of resources which was deleted along with the log file path. 
+  - The StepFunctions workflow also sends out another email when the whole Map state process completes successfully. Sample email template given below.

+
+```sh
+# Get the current Unix timestamp

+
+# Get the timestamp from 5 minutes ago
+FIVE_MINUTES_AGO=$(($(date +%s) - 300))000
