GetBucketPolicyStatus

get

Retrieves the policy status of a bucket, indicating whether the bucket is public.

IONOS Object Storage considers a bucket policy to be "public" if any statement in the policy is public. A statement is considered public if the Effect is Allow and the Principal has a wildcard -- unless there is an IpAddress:{aws:SourceIp} condition associated with the statement that restricts the requesting source IP to one or more specified IP addresses.

Permissions

You must be the contract owner or an administrator to perform this operation. If not, they can grant you permission to perform the s3:GetBucketPolicyStatus operation using Bucket Policy.

S3 API Compatibility

  • The x-amz-expected-bucket-owner header isn't supported.
