How to configure your CLI

- Powershell will prompt you with 4 questions
a) AWS Access Key ID (Sign in as admin IAM role -> security crendentials tab -> Access Keys )
b) Secret Access key: you can only show this when you first create a key (but there is no limit on how many or when you can create these keys)
c) default region: us-east-1
d) default output format: json, jaml, text, table
- CLI will store this information in a program called “default”
- this is used anytime want to run an aws cli command that doesn’t specify which profile to use
- saved in folder out of home directory - > .aws
