This is used to extract the AWS credentials with the sts assume-role command.
It will print the export command for the credentials.
Just copy & paste them in your terminal.
Use aws_extract_assume_role_creds.sh unset to unset the
environment envs. Also copy & paste that.
Example:
aws sts assume-role --role-arn arn:aws:iam::[ACCOUNT_ID]:role/[ROLE_NAME] --role-session-name [SESSION_NAME] | aws_extract_assume_role_creds.sh
