GetBucketPolicy

Note

This action gets a bucket policy for an Amazon S3 on Outposts bucket. To get a policy for an S3 bucket, see GetBucketPolicy in the Amazon S3 API Reference.

Returns the policy of a specified Outposts bucket. For more information, see Using Amazon S3 on Outposts in the Amazon S3 User Guide.

If you are using an identity other than the root user of the AWS account that owns the bucket, the calling identity must have the GetBucketPolicy permissions on the specified bucket and belong to the bucket owner's account in order to use this action.

Only users from Outposts bucket owner account with the right permissions can perform actions on an Outposts bucket. If you don't have s3-outposts:GetBucketPolicy permissions or you're not using an identity that belongs to the bucket owner's account, Amazon S3 returns a 403 Access Denied error.

Important

As a security precaution, the root user of the AWS account that owns a bucket can always use this action, even if the policy explicitly denies the root user the ability to perform this action.

For more information about bucket policies, see Using Bucket Policies and User Policies.
