#!/bin/bash

#### USAGE
# ./clean_up_gcp_project.sh <PATH TO SERVICE ACCOUNT KEY>

#### HOW TO FIND FILE PATH TO SERVICE ACCOUNT KEY
# 1. Navigate "IAM & Admin" > "Service Accounts" for the GCP Project you want to delete.
# 2. Click on one and choose "Edit", then "+ Create Key" to create a "JSON" key. This will
# download the file containing the key to your workstation.
#    - There may be multiple service accounts for a single GCP Project. 
#    - The [default serviceaccount](https://cloud.google.com/iam/docs/service-accounts#default) 
#      has a large number of permissions and may be a good choice.
#     - Consider updating this document with instructions on how to identify a default service account.
# 3. Copy the path to the file.
