S3 bucket policy settings

Hi Gouda!

Organizing your scenario:

1. Your bucket should be publicly accessible through a URL.
2. Anyone can retrieve objects from the bucket.
3. Only IAM users can upload (put) objects into the bucket.

You can use the following bucket policy to implement this:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "PublicReadGetObject",
            "Effect": "Allow",
            "Principal": "*",
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::YOUR_BUCKET_NAME/*"
        },
        {
            "Sid": "IAMPutObject",
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::YOUR_AWS_ACCOUNT_ID:user/YOUR_IAM_USERNAME"
            },
            "Action": "s3:PutObject",
            "Resource": "arn:aws:s3:::YOUR_BUCKET_NAME/*"
        }
    ]
}

Make right replaces on policy.

Remember to attach the necessary S3 permissions to the IAM user's permissions policy to allow uploading objects.

I'll keep tracking your comments to see if you've found a resolution.
