Use the right account to do this - avoid using same account as amazon.com
First, create your bucket, choose UE (Paris)
as a region. There is no property nor permission to define at this step.
We're using the same bucket for all environments, we'll use the environment name in the store_dir
(but only for non-production)
Then in AWS console, go to IAM
- create a user choosing "Programmatic access"
- in set permission, choose "attach existing policies directly"
