Notes

• The addition of the s3:CreateBucket action against the arn:aws:s3:::elasticbeanstalk-REGION-ACCOUNT_ID resource is critical for the creation of new Elastic Beanstalk application instances - even if the bucket itself already exists.
• Policy has been designed to work with single container Docker environments - not multicontainer, which are ECS cluster environments under the hood and requires additional IAM action permissions.

Had so many iam errors: had to add "elasticloadbalancing:ModifyListener", "elasticloadbalancing:describe*" as well. Replaced the multiple s3 actions with "s3:*"
