Question

How to set policy of space

I tried to use s3cmd to set policy of a space. The policy file is like:

{
    "Statement": [
        {
            "Sid": "Allow get requests referred by localhost",
            "Effect": "Allow",
            "Principal": {
                "AWS": "*"
            },
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::my-bucket/policy/*",
            "Condition": {
                "StringLike": {
                    "aws:Referer": [
                        "http://localhost:8080/*"

                    ]
                }
            }
        }
    ]
}

and then run

s3cmd setpolicy policy s3://my-bucket

The command run without error, but when get the info:

s3cmd info s3://my-bucket

It showed there is no policy on this space:

s3://my-bucket/ (bucket):
   Location:  sgp1
   Payer:     BucketOwner
   Expiration Rule: none
   Policy:    none
  ...

And I still can not access the private file at localhost.

Does space support setpolicy or I done something wrong?

Here is my bucket policy.json create from AWS S3 and It work with DO Spaces. Don’t forget to change to your bucketname and your domain.

{
    "Version": "2017-10-17",
    "Id": "http referer policy example",
    "Statement": [
        {
            "Sid": "Allow get requests originating from www.yourdomain.com and subdomain.yourdomain.com.",
            "Effect": "Allow",
            "Principal": "*",
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::yourbucketname/*",
            "Condition": {
                "StringLike": {
                    "aws:Referer": [
                        "https://www.yourdomain.com/*",
                        "https://subdomain.yourdomain.com/*"
                    ]
                }
            }
        }
    ]
}

                    ]
                }

Try to create policy.json instead policy and run s3cmd setpolicy policy.json s3://my-bucket If still don’t work recheck the policy.json path is correct.

It’s work for me.
