How to authenticate AWS EBS (Beanstalk) on ECS (Container Storage)? AccessDeniedException

Question

I'm new to using AWS EBS and ECS, so please forgive me if I ask a question which might be obvious for others. To the issue:

I've configured EBS and ECS in the same AWS cloud region. I've pushed my container and can see the image in ECS. The EBS environment has been built using a Dockerrun.aws.json pointing to the ECS. During the build of the EBS I get the following error:

2020/11/02 20:50:25.858567 [INFO] authenticate with ECR if the image is in an ECR repo
2020/11/02 20:50:25.858582 [INFO] Running command /bin/sh -c aws ecr get-login --no-include-email --registry-ids 731178912345 --region eu-west-1
2020/11/02 20:50:28.355911 [ERROR] An error occurred during execution of command [app-deploy] - [Docker Specific Build Application]. Stop running the command. Error: failed to authenticate with ECR for registry 731178912XXX in eu-west-1: Command /bin/sh -c aws ecr get-login --no-include-email --registry-ids 731178912XXX --region eu-west-1 failed with error exit status 255. Stderr:
An error occurred (AccessDeniedException) when calling the GetAuthorizationToken operation: User: arn:aws:sts::731178912XXX:assumed-role/aws-elasticbeanstalk-ec2-role/i-0bff9b5324348ea71 is not authorized to perform: ecr:GetAuthorizationToken on resource: *

I read somewhere that the identify is automatically passed in to process the authentication. I couldn't find any indication on what to do to resolve the issue. Maybe someone could help me out?

After adding the permission as discussed I get these:

Your aws-elasticbeanstalk-ec2-role instance role does not have permissions to execute ecr:GetAuthorizationToken.

You can address this, by adding an inline policy to the aws-elasticbeanstalk-ec2-role role:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": "ecr:GetAuthorizationToken",
            "Resource": "*"
        }
    ]
}

Please note that more permissions may be needed after this one. You can add them in the same way.
