How to access S3 bucket(private) objects from application hosted in Elastic Beanstalk.

Hello.

We need to configure an IAM role on the EC2 where ElasticBeanstalk is launched.
By setting the IAM policy required to access S3 for this IAM role, it is possible to retrieve S3 files from EC2.

Another method is to use CloudFront to make S3 images publicly available.
