Stepfunction EC2 SSM

This repo holds the stepfunction workflow for creating EC2 instance and execute remote powershell script for configuration of EC2 using Systems Manager (Run Command)

Description

There are scenarios where EC2 instances has to be created and need to be configured using Systems Manager powershell script. The script may take a long time depending upon the configuration and it may exceed lambda time limit of 15 mins.This solution provides a serverless approach using stepfunctions and lambda to create EC2 instance, execute the configurations from powershell script, wait for the script to complete by periodcally checking the runCommand status. The workflow also deletes the created EC2 instance irrespective of runCommand execution result.
