How do I enable my environment under Elastic Beanstalk to talk to S3 so that it can get the authentication info and then pull my Docker image from a private repository in a multicontainer environment?
I found the name of the IAM role in my environment's instance config ("aws-elasticbeanstalk-ec2-role"), went to IAM, opened the "AWSElasticBeanstalkWebTier" policy in order to extend it for S3 access to the ARN for my bucket, but these policies are "AWS Managed" and read-only. I tried merely attaching an existing S3 policy (e.g. AmazonS3ReadOnlyAccess, defined by AWS) to my instance-profile role, but the deployment failed and the logs still complain about not being able to access the private repository:

Does the config look correct?
