You can set the access control list (ACL) when you create a bucket, or modify the ACL for a created bucket. Only bucket owners can set or modify the ACL for buckets.
The following table describes the three types of ACLs for buckets.
| ACL | Description | Description |
|---|---|---|
| public-read-write | Public read/write | Anyone (including anonymous users) can read and write the objects in the bucket.
Warning All Internet users can access the objects in the bucket and write data to the bucket.
This may cause unexpected access to the data in your bucket, and cause an increase
in your fees. If a user uploads prohibited data or information, it may affect your
legitimate interests and rights. Therefore, we recommend that you do not set your
bucket ACL to Public Read/Write except in special cases.
|
| public-read | Public read | Only the bucket owner can perform write operations on the objects in the bucket. Other
users (including anonymous users) can perform only read operations on the objects
in the bucket.
Warning All Internet users can access the objects in the bucket. This configuration may cause
unwanted access to the data in your bucket, and cause an increase in your fees. Therefore,
we recommend that you exercise caution when you set your bucket ACL to Public Read.
|
| private | Private | Only the bucket owner can perform read and write operations on the objects in the bucket. Other users have no access to the objects in the bucket. |
