AWS profiles
When setting up profiles for AWS locally, start with your own credentials as default, then add profile entries for the different environments. e.g.
# ~/.aws/config
[default]
aws_access_key_id=AKIAIOSFODNN7EXAMPLE
aws_secret_access_key=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
[profile staging]
role_arn = arn:aws:iam::0987654321:role/staging
source_profile = default
region = ap-southeast-2
output = json
[profile prod]
role_arn = arn:aws:iam::5678901234:role/prod
source_profile = default
region = ap-southeast-2
output = json
