This script loads aws cli profile configure as aws environment configuration
#! /bin/sh
# aws cli works with both: environment variables and values configured with `aws configure`.
# If our own script come to use env variables, like in case where we need to guess the url of a ECR reposiroty,

# This script does just that!
