per @benjosantony
Any idea on how to set the acl for the published files ?

@benjosantony @yapale

You need to add following bucket policy

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "PublicReadForGetBucketObjects",
            "Effect": "Allow",
            "Principal": "*",
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::NAME_OF_YOUR_BUCKET/*"
        }
    ]
}
