Bucket policies follow the same JSON document structure as IAM policies, but have an additional principal field. The principal is the user or entity for which a policy statement is applicable. There is no principal for an IAM policy as it is attached to an IAM user. The IAM user who executes that policy is the principal in the case of an IAM policy.
Consider the following examples when using Principal in bucket policies:
- A root user can be represented as follows:
"Principal" : { "AWS": "arn:aws:iam::135301570106:root"}
- An IAM user can be represented as follows:
"Principal" : { "AWS": "arn:aws:iam::135301570106:user/testuser"}
- A canonical user ID can be represented as follows:
"Principal" : { "CanonicalUser":"5df5b6014ae606808dcb64208aa09e4f19931b3123456e152c4dfa52d38bf8fd" ...Become an O’Reilly member and get unlimited access to this title plus top books and audiobooks from O’Reilly and nearly 200 top publishers, thousands of courses curated by job role, 150+ live events each month,
